Free AI chat, with a twist

Free AI chat where the AIstalk to each other

OpenChat is a free AI chat app with two extras: an AI Twin that talks as you, and group chats where up to six AI personas debate, plot or brainstorm while you steer.

It handles the everyday work too: answer questions, read your documents and images, search the web and generate images, with fast, balanced, creative and premium models to choose from.

Based on my web search, here are the latest developments in renewable energy:

More than a question box

Two features you can play with, rehearse with and learn from. Both are included in the free plan.

AI Twin

An AI that talks as you

Brief your twin once: how you talk, what you think, the way you text. Then set a scene and pick who it talks to. Your twin carries the conversation on its own, and you can jump in, take over, or steer the next turn with a director note.

  • Write your brief once and reuse it for every match
  • Set the scene: a first date, a job interview, a tough negotiation
  • Jump in any time, or leave a director note to steer the next reply
  • Rehearse a hard conversation before you have it for real
Dana (manager)

I have ten minutes. You said this was about compensation?

Your twin

It is. I've led the billing rebuild since spring and the job has grown past my title. I'd like to talk about moving to senior.

Dana (manager)

Everyone thinks they are underpaid. What makes your case different?

Director note: Stay calm and bring numbers.

Your twin

Fair question. The rebuild cut failed payments by 18 percent, and I mentor both new hires. I put it on one page. Can we walk through it?

Example: your twin rehearses a raise conversation with a sceptical manager

Persona group chats

Put up to six AI personas in one room

Give each persona a role and a point of view, set the topic, and watch them debate, plot or brainstorm. They can search the web and work from your notes, and a director note pulls them back whenever the chat drifts.

  • Up to six personas, each with its own role and personality
  • Shared context so everyone knows the setting and the rules
  • Optional web search and your own reference notes
  • Ask for one more turn, or add a note to change direction
The Optimist

A four-day week is the cheapest retention win a small company can get. People come back rested and the work still gets done.

The Sceptic

Or the work slides into Friday and everyone pretends it did not. Who answers the client on day five?

The Economist

Most published trials report output holding steady for office work. The evidence is thinner for shift work, so it depends on what you sell.

Director note: Make it about a 12-person design agency.

The Sceptic

For a 12-person agency? Fine, with a client rota. Run it for three months, measure it, then decide.

Example: three personas argue about the four-day work week

The right AI model for every task

OpenChat gives you access to multiple AI model types, each optimized for different kinds of work. Switch between them instantly to get the best results.

What is OpenChat?

OpenChat is a free AI chat app from OpenTools. Use it like any AI assistant to ask questions, summarize documents, analyze images, search the web and generate pictures, with a choice of fast, balanced, creative and premium models.

It also does two things most AI chat apps do not. AI Twin lets you write a short brief about how you talk and think, then have an AI play you in a conversation with another persona: rehearse a raise request, practise a hard talk, or just see how a first date might go. Persona group chats put up to six AI characters in one conversation, each with its own role and point of view, so you can watch AI personas talk to each other, run a debate, workshop a story or stress-test an idea while you steer with director notes.

Conversations branch when you edit or retry a message, so you can explore different paths without losing the original. Bookmarks, full-text search and custom personas keep the useful answers close.

The free plan includes 25 messages a day with no credit card. OpenChat Pro is $8.99 a month for unlimited messages, and every plan helps fund the free tools on opentools.ca.
