Frequently Asked Questions

Last Updated: November 20th, 2025.

General Overview

Answer: Hashchats (#chats) is a collaborative AI messaging platform designed to transform how people interact with artificial intelligence by making it a shared, social experience. Unlike traditional AI tools built for solo use, Hashchats integrates AI directly into group chats and leverages a crowdsourced hashtag system to simplify prompt engineering. This allows individuals and teams to access community-tested prompts, collaborate in real time, and get better results from AI together.

Answer: Whether working solo or in a group, Hashchats helps you get better results through multi-model AI integration, smart prompt suggestions, and a collaborative environment. With both public and private hashtags, you can discover or build prompts tailored to your needs.

Answer: Hashchats brings together private AI chats, direct messages, and group chats into one platform. You can interact with AI one-on-one, summon AI in group conversations by toggling @ai, and apply hashtags to instantly run optimized prompts. The platform automatically selects the best AI model and configurations behind the scenes based on your prompt and AI model tier.

Answer: No. Hashchats does not use your data to train any AI models. Hashchats also does not use any AI services or API providers that use user data for model training.

Answer: Yes, you can sign up with a free account and use Hashchats with our mobile app, available on both iOS and Android, as well as our web app.

Answer: Hashchats works on the web and is compatible with both desktop and mobile browsers.

It also has native mobile apps for iOS and Android. The iOS app works on most iPhones and iPads, and the Android app works on most Android smartphones and tablets.

Free Plan

Answer: Hashchats offers a free tier with limited AI usage so new users can explore the platform and try out its features. Free users can participate in group chats, view AI responses to pro users' requests, and use a limited amount of AI until they have used up their free credits. To unlock much higher AI limits with included credits and optional pay-per-use for heavy usage, you can upgrade to a Pro subscription.

Note that free users cannot upgrade to a subscription directly through the mobile apps. To purchase a Pro Plan, you must use the Hashchats Web App.

Answer: Yes, free users can continue using Hashchats after their credits are used up. You can still chat with friends and colleagues in DMs or group chats without limits, but you won't be able to summon AI yourself. However, you can still see AI responses when Pro users toggle @ai in group chats.

Answer: Unused free credits never expire. You can check your Account Management page to see your remaining balance anytime.

Answer: We have automatic systems in place to detect spam-like behavior i.e. cases where the same device or the same individual attempts to sign up multiple times. If flagged, accounts may not receive any free credits at signup. This process is automated and there are no exceptions. We do this to keep things fair for everyone and to grow responsibly.

Pro Plan

Answer: The Pro plan costs $20 a month, billed in USD, with a seamless transition to a pay-per-use plan for any usage beyond the included allocation.

Answer: The $20/month Pro subscription includes everything available to free users, plus $20 in AI usage credits each month to access AI-specific features. These features include private AI chats, group collaboration with the ability to summon AI whenever needed, and a real-time AI usage summary. This means you can generate Text, Images, Video, and Audio using AI, up to a total of $20 each month. After that, pay-per-use pricing applies for the rest of the billing period.

AI Usage Pricing Details & Breakdown

Text Price / 1K Tokens Tokens / $20 Best For
Advanced $0.010 2M Fast, powerful, and intelligent responses

Note: Our Text AI's Advanced tier can automatically select reasoning or search models when it determines that your prompt requires deeper thinking (e.g., complex inquiries) or searching the web for more up-to-date information. These include internal "thinking" or "reasoning" steps as well as webpage content as context, which are part of the token usage. You won't see these tokens generate, but they help make responses smarter and more accurate.

Images Price / Image Images / $20 Best For
Masterpiece $0.100 200 Stunning, top-quality, premium images

Note: Our Image AI's Masterpiece tier can automatically select different AI models for different purposes but is always priced the same per image.

Videos Price / Second Seconds / $20 Best For
Shorts $0.100 200 Amazing, high-quality, short clips

Note: Our Video AI's Shorts tier can automatically choose to generate a video of 5 or 10 seconds depending on your prompt. It always defaults to 5 seconds when unsure.

Audio Price / Second Seconds / $20 Best For
Music $0.010 2K Studio-quality vocals or instrumentals

Note: Our Audio AI's Music tier can automatically choose to generate a song between 10 seconds all the way to 5 minutes. For the time being, all AI-generated audio will count as 10 seconds when it comes to pricing (i.e. whether you generate a 5 minute song or 30 second song, you'll only be charged for 10 seconds of audio per song.). This is subject to change at anytime.

Answer: Once you exceed your $20 in included usage, you'll automatically transition to pay-per-use billing at the same rates. AI usage is tracked in real time and shown in your usage summary on the Account Management page. Any overages are automatically billed in your next billing cycle.

Answer: You can check your real-time usage summary anytime on the Account Management page. It provides a breakdown of your text, image, and video usage for the current billing period in real-time.

Answer: Tokens are units of text that Hashchats' AI processes, roughly equivalent to pieces of words. For English text, you can estimate:

  • 1 token ≈ 4 characters
  • 1 token ≈ ¾ words
  • 100 tokens ≈ 75 words
For example, 1-2 sentences are about 30 tokens, and a paragraph is around 100 tokens. Token counts vary by language (e.g., "Cómo estás" in Spanish is 5 tokens for 10 characters). To calculate the exact token usage for your prompts, use OpenAI's Interactive Tokenizer Tool, which shows how text is split into tokens. Note that tokenization may differ slightly depending on the AI model used.

Answer: Yes, you can cancel your Pro subscription plan anytime through one of the following options:

  • Billing Portal: Go to your Account Management page, select Manage Subscription, and cancel via Stripe.
  • Account Deletion: On your Account Management page, choose Delete Account to permanently remove all data and cancel your subscription.
Note: Deleting your account is irreversible and will result in the loss of all associated data.

Answer: We accept all major credit cards, Apple Pay, Google Pay, and Buy Now, Pay Later options (e.g., Affirm, AfterPay, Klarna) via secure Stripe payments.

Answer: We don't offer refunds for canceled subscriptions. If you're facing technical issues, reach out to [email protected], and we'll help resolve them.

Private Chats

Answer: Tap New Chat, select your preferred AI model and tier, toggle @ai, and type your message. You can invite people to convert the conversation into a 1-on-1 or group chat with people anytime.

Answer: From the AI tab, select the More button on a chat and choose Delete Chat. When you're inside a chat, you can also tap the chat name and select Delete Chat to delete it.

If you delete a chat, all messages and media within the chat will be deleted forever.

Chats with multiple people cannot be deleted but can be exited at any time. Deleting a private AI chat affects only you and exiting a multi-participant chat doesn't delete it for others.

Chats with People

Answer: To chat with someone who isn't already one of your contacts, open the chat you want to invite them to and tap the Add People button on the top-right corner. Here's how you can invite people to chat with you:

  • Copy Link: This generates a unique invitation link you can share through any online communication channel (such as existing messaging apps, social media or email). The link remains active for 23 hours before expiring automatically for security reasons. Anyone who opens it during that window can join the chat instantly.
  • Email Invite: Enter the email addresses you want, and Hashchats will send a personalized email containing the invitation link to each of the invited emails.
  • QR Code: Displays a scannable code that people nearby can use to join immediately. No link sharing or contact exchange required.

To start a chat with someone who is already a contact, tap the Add People button on the top-right corner first. Then choose someone from the list of your existing Hashchats contacts to add them directly. No invitation link is needed.

Once someone joins, Hashchats shows a notice in the chat, and the new member can view the full conversation history. You can generate new invite links anytime (expired links can't be reused). If someone has trouble joining, check that the link is still active, ensure they have the app installed, and verify that any email addresses were typed correctly.

Answer: Group chats support up to 100 participants. Any pro user (or free user with AI credits) in the group can toggle @ai to bring AI into the conversation, enabling real-time assistance for everyone. Free users can participate in the chat and view AI responses, but their ability to interact directly with the AI is limited. This makes collaboration with AI seamless in team settings.

Answer: Yes, but only if you are the chat creator (admin by default) or have been transferred the chat admin status. To remove a participant as a chat admin:
  1. Open the chat and tap the "More" menu.
  2. Tap the chat name OR select "Chat Participants".
  3. Tap the "More" option next to the person you want to remove.
  4. Select "Remove Participant".

Answer: Each chat can only have one admin. By default, the chat creator is the admin. To transfer admin status:
  1. Open the chat and tap the "More" menu.
  2. Tap the chat name OR select "Chat Participants".
  3. Tap the "More" option next to the person you want to make admin.
  4. Select "Transfer Admin".

Answer: Chats with multiple participants cannot be deleted, but you can leave them at any time. From the People tab, select the More button on a chat and choose Exit Chat. When you're inside a chat, you can also tap the chat name and select Exit Chat to leave it.

When you exit a chat, all other participants will remain, and the chat's message history will stay visible to them.

If you are the last remaining participant in a chat, exiting it will automatically delete the chat as well.

Chat Messages

Answer: To reply to a message on mobile, simply swipe the message from right to left. On the web, hover over the message for a moment, then click the reply icon to respond.

Answer: To forward a message on mobile, simply double-tap a message and then select the chat to forward it to. On the web, hover over the message for a moment, click the forward icon, and then select the chat to forward the message to.

Answer: You can only share media (photos, videos, audio, and files) on mobile by tapping the share icons. On the web, sharing outside of Hashchats is disabled by default but you can always download media.

Answer: To download a message's text on mobile, tap a message and then tap the download icon. On the web, hover over the message for a moment, then click the download icon. You can then download it as plain-text or markdown format.

To download media (photos, videos, audio, files) on the web or mobile, tap the download icon to download it.

Answer: On mobile, swipe the message from left to right to see a list of viewers (with reactions, if any). On the web, hover over the message and click the eye icon to view the list of viewers and reactions.

Answer: When @ai is off, you can attach files, images, videos and audio using the attachment icon. You can send GIFs using the GIF button, and share links by simply adding them to your message text.

When @ai is on:

  1. Text AI: Upload up to 8 files, images, videos, or audio, plus any links. All inputs will be used to generate text.
  2. Image AI: You can attach up to 8 images only. Other file types are ignored.
  3. Video AI: You can attach only 1 image. All other inputs are ignored for video generation.
  4. Audio AI: You cannot attach any files, images, videos, audio, or links.

Answer: Yes. Tap the record button to record a voice message and send it. Voice messages are automatically transcribed, and you can edit the transcription or attach images, videos, or files along with the voice message.

Answer: You can attach up to 8 attachments in any combination of images, videos, audio, or files. Each attachment can be up to 32MB. Images and videos may be optimized before storage. Large files can be reduced to fit under 32MB, but they will be rejected if the optimized version still exceeds the limit.

For message lengths, a maximum of 128K characters is allowed when @ai is off. For Text AI, the maximum message length is also 128K characters. For image, video, or audio generation, the maximum allowed message length is 8K characters.

Answer: If you send a text message, or a message that contains text while @ai is off, you can edit the text content for a short time after sending it. To edit, tap the more options button on the message and then tap Edit message.

You can edit the message text for up to 15 minutes after it was sent. Attachments (photos, videos, audio, or files) cannot be edited or replaced, and any push notifications that were already delivered to other participants will not be updated when you edit the message text.

If you send a text message, or a message containing text while @ai is on, it cannot be edited.

Answer: If you send a message while @ai is off, you can delete it at any time by tapping the more options button on the message and selecting Delete.

Deleting a message removes it from the chat, but any push notifications that were already delivered to other participants will not be removed.

Messages sent while @ai is on cannot be deleted.

Using AI in Chats

Answer: Yes. Hashchats supports all text, image, video, audio (songs) generation. Based on your prompt, the platform automatically selects the best model and AI configurations behind the scenes.

Answer: An AI-generated message is any response generated by Hashchats' AI—text, image, video, or audio—sent in either private chats or people chats.

Answer: When Text AI is used, Hashchats includes the last 20 messages with full content as context.

For image, video, and audio generation, message history is ignored; only the prompt (including hashtags) is used.

Answer: When you reply with @ai, Hashchats only uses the replied-to message as context. Hashchats prioritizes the replied-to message over the broader message history.

  • Text AI: Uses all media/text in the replied-to message.
  • Image AI: Edits images; uses text as prompt; ignores audio/video/links.
  • Video AI: Uses first image only or text as prompt; ignores others.
  • Audio AI: Ignores all content of the replied-to message.

Answer: Hashchats automatically selects the most advanced and suitable model for your task—whether text, search, image, video, or audio generation.

Answer: Besides tapping the toggle, keyboard shortcuts are available (web only):

Platform Shortcut Keys Function
MacOS Option + a
Option + 2
Option + @
Toggle @ai on/off
Windows/Linux ALT + a
ALT + 2
ALT + @
Toggle @ai on/off

You can also type @ai in the message field to activate it.

Answer: Yes. Hashchats can automatically detect what you're trying to create and switch modes accordingly. You can manually override this by selecting a model, which pauses auto-switching until the next session.

Hashtags & Prompt Engineering

Answer: Hashchats supports public and private hashtags. Public hashtags are shared prompts created by users and ranked through community voting. Private hashtags are visible only to you and are ideal for personal or project-specific tasks. Hashtags make prompting easier and more efficient.

Answer: From the Home page, tap New Hashtag. Choose a model, add your prompt and a short description, and then select if it's public or private. If you want the hashtag to stay active for the entire chat (e.g. having a chat with a famous person), so you or others don't have to keep searching for and selecting the hashtag, simply turn on the Is Conversational toggle. If Is Conversational is off, you'll also see an option to turn on Search Enabled for text-based hashtags that need real-time searches, like top 10 news updates. Once created, you can reuse your hashtag anytime to use the prompt without retyping it.

Answer: When you select the @ai toggle, the #tag button will appear, where you can search for hashtags. Trending hashtags are displayed first by default. You can use the search bar at the top to find specific hashtags based on keywords, topics, or categories.

Answer: Public hashtags are ranked based on how often they're used and how helpful the community finds the responses. Popular and effective hashtags naturally rise to the top through upvotes and frequent use.

Answer: Yes, while users only see a hashtag's description, you can report any hashtag that generates content violating our community guidelines—such as hate speech, discrimination, or explicit material. Reported hashtags are reviewed and removed if necessary.

Contacts Management

Answer: Your contact list shows people you've interacted with in DMs or groups in the past. Hashchats doesn't sync external contacts. Only a name and profile photo are shown. You can tap any contact to start a new chat with them, anytime.

Answer: Removing a contact deletes both users from each other's Contacts lists. To reconnect, a new invite must be sent and accepted. Once a contact is removed, you or the ex-contact cannot start a conversation with each other UNLESS you join via an invitation link.

Answer: Blocking and removing a contact will delete both you and your contact from each other's contact lists. You will also be removed from all chats where the removed contact is a participant.

To reconnect, a new invite must be sent and accepted. Once a contact is blocked & removed, you or the ex-contact cannot start a conversation with each other UNLESS either of you join a shared chat via an invitation link.

Account & Security

Answer: Hashchats is built with security and privacy at its core. We use secure authentication methods including Google, Apple, and email/password login, along with standard encryption and strict access controls. Your conversations are protected at every step, and group chats are invite-only to ensure that access is always intentional and secure.

Answer: Your data is securely stored, and private chats with AI can be deleted at any time through your AI chats tab. After deletion, your data is permanently removed unless required to be retained by law.

Answer: Go to your Account Management page and tap Delete Account. This action is permanent and will immediately remove all your data and log you out.

Answer: When you delete your Hashchats account, all personal information like your name, profile photo, and account data is permanently removed. However, any messages or media (like photos or videos) that you shared in direct messages or group chats will remain visible to recipients as part of their chat history. This helps preserve the conversation flow for others but your name and photo will be anonymized. If you'd like specific messages or files deleted, please remove them manually before deleting your account.

Support

Answer: Hashchats currently supports only English. The AI models that Hashchats uses are multilingual and can understand and respond back in most popular languages.

Answer: We're available 24/7 through our AI-powered customer support agent, which you can use to quickly ask any questions. If needed, you can also request live chat support with a human directly inside the customer support chat. Alternatively, you can email us at [email protected] for further assistance.
