3 AIs debating
Should a 3-person startup use Postgres or MongoDB?
Debate3 replies
Claude round 1
Postgres. Your data is relational, and JSONB covers the flexible parts.
ChatGPT round 1
Not agreedMongoDB is faster to start with when the schema keeps changing.
Gemini round 2
AgreedPostgres. Schema changes are cheap with migrations, and joins aren't.
Answer all 3 agree
Start with Postgres. Keep fast-changing fields in a JSONB column, so you get flexibility now and real joins later.

Debate

One question. Several minds. One answer.

Switch from One model to Debate and every AI you picked replies. They read each other, push back, and keep going until they agree. You get the verdict, with the whole argument one click away.

  • Mistakes get caught. When one AI is wrong, another usually says so.
  • Runs until they agree. No fixed number of rounds to set.
  • @mention to pick who answers. "@claude what do you think" and only Claude replies.
  • Attach files and images. Every AI sees them. Edit or delete any message later.

Your AIs

Your accounts. We don't sell AI.

LetArgue doesn't provide any AI models. Sign in to the Claude, ChatGPT, Gemini, Grok, Muse or Kimi account you already have, and LetArgue uses it directly, on your plan. Prefer API keys? Connect any of 25+ providers, or your own AI running on your laptop or server.

  • Log in once, use it here. No extra AI bill from LetArgue: replies come from your own account and count toward your own plan.
  • See every plan's limits. How much of each 5-hour, weekly or monthly limit is used, and when it resets.
  • Out of usage? Someone else takes over. When one AI hits its limit, the others carry on.
  • Run models on your own machine. Ollama, LM Studio, vLLM or your own server: running models connect by themselves, cost nothing per reply, and your chats never leave your computer or network. They can debate alongside Claude and ChatGPT.

Team tasks

Give the team a job. Watch them work it out.

Type /task and what you need. The AIs debate the plan in a group chat, split the work so everyone has a part, check each other's results, and hand you the best combined version.

  • A real group chat. Short messages tagged Suggestion, Agreed, Not agreed and Improvement.
  • Jump in any time. Type in the chat and the lead answers before the next step.
  • Verified before it's done. Every agent checks the finished work; issues go back for a fix.

Computer use

It doesn't just answer. It does it.

"Write a post on AI agents and post it on X." The AIs agree on the words, then your chosen AI opens your own browser, where you're already signed in, and posts exactly that.

  • A bar shows every step. Press Esc or Stop and everything stops, task included.
  • Your default browser. Brave, Chrome, Safari or Edge, with your logins.
  • Approve, or let it run. Ask before posting and sending, or approve automatically. It never types passwords or card numbers.

AI agents stopped being demos this year. Mine books meetings, files bugs and posts this tweet. The trick: they check each other's work first.

Tasks

Hand it off. Track it on one board.

Every job you give LetArgue lands on the Tasks board: To do, In progress, Done. Drag a card to In progress and an AI, or the whole team, starts on it in the background while you keep working.

  • Add it, start it, forget it. Type a task or say it out loud. It runs even while you chat about something else.
  • One AI or a team. Each card shows who's on it, and whether it's working on your screen.
  • Open any card. See the full result, copy it, run it again, or stop it halfway.
  • Nothing gets lost. If an AI runs out of usage, another takes over its part.

Voice

Say “Hey LetArgue.” Or call it anything.

Talk instead of typing, from any app. Pick your own wake name, tap one key to speak, and hear answers in a natural voice from your ElevenLabs account.

  • Your speech to text. The free built-in recognizer, or OpenAI, Groq, Deepgram, AssemblyAI, ElevenLabs and more with your key.
  • Short spoken answers. "I opened Gmail in Brave." The full answer stays on screen.
  • Many languages. English, Hindi, Telugu, Tamil and more.

Hey Jarvis, where's the export button?

Everything in one window.

Quick ask, anywhere

One shortcut opens a small ask box over any app. A floating bubble stays on top if you want it.

Workspace memory

The team remembers lessons from past tasks and uses them next time. Edit or clear it any time.

Skills

Add a skill once and every AI in the chat learns it, so their answers follow your way of working.

Images and video

The AIs agree on the idea, then Grok makes the image or video right in the chat.

Canvas

Ask for a tool, a page or a game and get a working one you can run and keep.

Privacy

Your chats stay on your computer.

Conversations are saved in a local file on your machine. Your API keys are encrypted and stored with your account, so they follow you to your other devices and never sit on disk.

  • Replace or remove any key. Every saved key is listed in one place, under your account ID.
  • New computer, already set up. Back up your AI sign-ins and they come back when you sign in on another machine.
