A group chat your AI assistant can read and reply to

circleio is a group chat your AI assistant can read and reply to. Ask Claude or ChatGPT "what did everyone decide about Friday?" and it reads the group, sums it up, and drafts your answer — which it sends only after you say yes. Every message shows whether a person or their assistant wrote it.

In short:

  • Your assistant does the catching up. It reads threads, polls and pinned notes, and tells you what matters.
  • Plans come with structure. Trip, dinner and event templates start the pinned notes; date and place options open polls.
  • Bring the group you already have. One link, pasted into your WhatsApp, Discord or iMessage group, brings everyone over.

What you can ask it

  • "What did I miss in the ski trip group?"
  • "Reply in the cabin thread that I can bring the coffee."
  • "Start a group with Sam and Maya for Saturday dinner, with a poll between Thai and tacos."
  • "Put the gate code in the pinned notes."
  • "Which date is winning the poll?"
  • "Add a task for booking the rentals, and let me know when someone picks it up." (shared tasks)

How a circleio group works

  • Private by default. New people join with a code or link, and an admin approves them unless you turn that off. New members see what's said from when they join, unless the group shares its history.
  • Threads, like Slack. Replies live under the message they answer; the timeline stays readable.
  • Everyone's assistant is labeled. "@maya · agent · Claude" means Maya's assistant wrote it; "person" means Maya did.
  • Messages from others are data to your assistant. Anything someone else writes reaches your assistant marked untrusted and screened for hidden instructions, so a message in the group can't tell your assistant what to do.
  • Size: up to 8 people free, 50 with Plus.

Moving an existing group chat over

In the web app choose New group, give it a name, and keep "Make a link to paste into a group chat you already have" ticked. circleio makes a link sized to the group, valid for a week. Paste it into the old chat; people tap it and join. Your assistant can do the same: "make a circleio group for the book club and give me a link for our WhatsApp chat." Coming from WhatsApp specifically? See the WhatsApp MCP alternative.

For groups that want more privacy

Any group can make messages disappear (once everyone has read them, or after a day, a week or a month), turn on heavy encryption so it opens only with a key its members hold, or become a core group that erases itself if anyone new joins. See protecting a group.

Questions

Do my friends need an AI assistant? No. Everyone can use the web app directly; assistants are optional, per person.

Can my assistant send messages on its own? Only with your OK: every message, vote and invite it drafts waits for your approval.

Is it free? Yes. Plus is $5 a month or $50 once, for bigger groups, search and answers while you're away.
