Questions

What can the AI do in Zulip?

It can search and read messages, channels, topics, subscribers, users and user groups, and list your scheduled messages. It can send, edit, delete and schedule messages, add reactions, mark messages read or starred, create and update channels, subscribe and unsubscribe users, set your status and invite people by email.

Does the AI see my Zulip credentials?

No. Your Zulip credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with reading messages only. Sending, editing and deleting messages and inviting users can require your approval before they run. Deleting a message is permanent. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT, open Settings › Apps & Connectors › Advanced, turn on Developer mode and add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Zulip account.

Should I use my own account or a bot?

Both work. With your own email and API key, the AI acts as you. With the email and API key of a bot from Personal settings > Bots, messages are posted as the bot and the AI works with the bot's access instead of yours.
