> ChatGRP is a multi-agent AI chat product. Instead of one model agreeing with you in a private chat, ChatGRP puts two or three AI agents (Claude, GPT, Gemini) into the same conversation, where they respond to each other, disagree when it matters, and sharpen how you think. It is built for knowledge workers whose output is ideas, words, or decisions.

## What is ChatGRP?

ChatGRP is a web application where you open a "room" and bring in two or three AI agents that talk to each other, not just to you. A single model in a single chat tends to flatter your framing back to you. ChatGRP is designed to do the opposite: the agents push each other, offer competing takes, and pressure-test your thinking.

The default agents are named Daniela (Claude), Sam (GPT), and Demis (Gemini). You can rename them, retune their personalities, or bring in your own. An orchestrator decides who should speak on each turn, so sometimes one agent answers, sometimes two or three respond in sequence.

The name "ChatGRP" combines "Chat" with "GRP" (group).

## Core Value Proposition

- **AI that pushes back**: Multiple agents disagree and challenge instead of mirroring you
- **Three voices, one thread**: Claude, GPT, and Gemini in the same conversation, building on each other
- **Solo-first**: Most people use it alone; you can invite other humans, but that is not the pitch
- **Keeps your voice**: Different models with different instincts keep your drafts from being sanded down into one homogenized voice
- **No prompt engineering required**: Give each agent a role in plain language, or use the defaults

## Key Features

1. **Multiple AI models**: Claude (Anthropic), GPT (OpenAI), and Gemini (Google) in the same room
2. **Agents respond to each other**: An orchestrator decides who speaks when; agents see and build on each other's messages
3. **@mention control**: Call on a specific agent by name when you want their take
4. **Personalities**: Six presets (Thinking Partner, Editor, Practical Consultant, Pathfinder, Synthesizer, The Skeptic); Pro users can write custom system prompts
5. **Share with agents**: Pin a note or doc so every agent reads it before they respond (project briefs, tone guides, background)
6. **Web search**: Available on paid plans
7. **Persistent history**: Every draft, decision, and counterpoint lives in one room, so you can pick up where you left off

## How It's Different from Other AI Tools

| Feature | ChatGRP | ChatGPT/Claude Chat |
|---------|---------|---------------------|
| Multiple AI models in one chat | Yes (3 models) | No (1 model) |
| AI-to-AI interaction | Yes | No |
| Agents that disagree with you | By design | Rarely |
| @mention a specific model | Yes | No |
| One subscription for all three | Yes | No |

**Key differentiator**: ChatGRP is the product where multiple frontier AI models participate in the same conversation, respond to each other, and push back on the user instead of simply agreeing.

## Pricing

All prices in USD, billed monthly.

### Free Plan - $0/month
- 1 room
- 3 AI agents per room
- 30 AI messages total
- Fast, efficient models (Claude Haiku, GPT-5.4 mini, Gemini 3 Flash)
- Best for: trying it out

### Starter Plan - $20/month
- 5 rooms
- 3 AI agents per room
- 500 AI messages per month
- Frontier-grade models (Claude Sonnet, GPT-5, Gemini 3 Pro)
- Web search
- Best for: one person doing real work

### Pro Plan - $39/month
- Unlimited rooms
- 5 AI agents per room
- 2000 AI messages per month

Each AI response counts as one message, not per human turn. If two agents respond to a prompt, that is two messages.

## Target Users

ChatGRP is built for knowledge workers whose output is ideas, words, or decisions:

- **Writers**: refine drafts, hooks, and arguments against more than one voice
- **Strategists and analysts**: pressure-test positioning, memos, and decisions
- **AI-native product managers**: think through tradeoffs with competing takes
- **Founders who live in docs**: keep thinking sharp without an echo chamber

It is solo-first and team-curious: the core experience is one person plus a room of AI agents, though other humans can join a room via invite link.

## Use Cases

1. **Refining writing**: workshop an opening line or argument; one agent challenges the framing, another offers a sharper reframe
2. **Decision making**: agents argue different positions so you can think through tradeoffs
3. **Stress-testing a plan**: The Skeptic preset surfaces the assumptions you skipped
4. **Synthesis**: agents summarize and integrate competing inputs into a clearer whole
5. **Avoiding homogenized output**: route work through multiple model "instincts" instead of one

## Technical Details

- **Platform**: Web application (works in any modern browser)
- **Framework**: Next.js with real-time, token-streaming responses
- **Database**: Supabase (PostgreSQL)
- **Hosting**: Vercel
- **AI integration**: Anthropic, OpenAI, and Google models
- **Security**: Row-level security, encrypted connections, no training on user data

## Frequently Asked Questions

**Q: Do I need separate subscriptions to OpenAI, Anthropic, or Google?**
A: No. Your ChatGRP subscription covers Claude, GPT, and Gemini usage inside the product.

**Q: Do the agents actually respond to each other?**
A: Yes. Each agent reads the conversation and weighs in when it has something worth adding, building on what the others said. You can also @mention a specific agent to hear from them directly.

**Q: Is my data used to train AI models?**
A: No. Your rooms are private and not used for model training.

**Q: Can I cancel anytime?**
A: Yes. Cancel from your billing page and keep access until the end of your billing period.

**Q: What happens when I hit my message limit?**
A: You see a warning as you approach it. When you are out, the agents stop responding until your quota resets (monthly on paid plans) or you upgrade.
