Persistent room rules with rule!
The new rule! command lets you set persistent rules for a room — standing instructions the AI follows in every reply, not just the next one. Under the hood it's backed by a new rule neuron type, so a rule becomes a first-class knowledge node in the room's brain alongside skills, knowledge, processes, and memory. Tell a room "always answer in bullet points" or "keep responses under 100 words" once, and it sticks.
Reply to any message
You can now reply to a specific message in private rooms. Tap reply, and the composer shows a banner quoting what you're responding to; the sent message carries a quoted header you can tap to scroll back to the original. The reply reference is saved with the message, so threads survive a refresh.
The part that makes it more than cosmetic: the quoted message is injected into the AI's context. When you reply to an earlier point and ask Cortez to expand on it, the AI knows exactly which message you mean instead of guessing from recency. The whole feature is gated to respect end-to-end encryption — in E2EE rooms the quoted snapshot is handled so it never weakens the room's encryption guarantees.
Markdown attachments
Building on file uploads, GroupGPT now accepts Markdown (.md / .markdown) files in the composer — joining the images, PDFs, and Word docs already supported. The file's text is extracted and read by the AI just like any other attachment, with the .md extension treated as authoritative so notes, READMEs, and docs come in as the structured text they already are.
Preview files and images without leaving the chat
Attachments are no longer just things you download to look at. Tap an image or a file and it opens in a full-screen preview viewer layered over the chat. Images get real inspection tools — pinch/scroll to zoom up to 6×, drag to pan — and when a message has several images you can swipe through them as a gallery. Markdown files render formatted in the same overlay, and anything you'd rather keep is one tap to download. It's the difference between "here's a file" and "here, take a look."
One-tap install
The service worker from the last release now has a front door. A PWA install button and a dismissible install banner let you add GroupGPT to your home screen or desktop in one tap — launching it in its own window, no browser chrome, like a native app. It's the payoff of the installability groundwork: GroupGPT stops being just a tab.
Also in these two days
- Invite via link got a smoother flow for getting people into a room.
- A bolder icon set with uniform toolbar spacing and a dedicated E2EE icon, plus a round of mobile polish.
Why it matters
Rules and replies both make conversations smarter in context: a room can now carry standing behavior, and a reply can point the AI at exactly the message you mean. Markdown attachments meet developers and writers where their content already lives. And the one-tap install closes the loop opened by the service worker — GroupGPT now installs and launches like the app it behaves as.
