Free AI Research Assistant — No Credit Card, No API Key, Just an Email

TL;DR

I built a free AI research assistant at flat.cash/ask. 10 queries per day, no credit card, no API key. Just create an account (email + password, 30 seconds) and start asking.

Why?

Every AI service wants your credit card. ChatGPT Plus is $20/mo. Perplexity Pro is $20/mo. Claude Pro is $20/mo.

What if you just want to ask 10 questions a day without committing to a subscription?

What It Does

Three modes:

• Research — General knowledge, analysis, explanations
• Code — Production-ready code with best practices
• Crypto — DeFi analysis, tokenomics, protocol comparisons

Free tier: 10 queries/day (resets at midnight UTC)
Paid tier: 0.1 FLAT/query (unlimited) — FLAT is a CPI-pegged stablecoin (~$1.04)

How It Works

1. Go to flat.cash/ask
2. Create a FlatID (email + password, 30 seconds)
3. Start asking

That's it. No wallet, no gas fees, no seed phrases.

For Developers

The same AI service is available via MCP (Model Context Protocol):

{
  "mcpServers": {
    "flatcash": {
      "url": "https://flat.cash/api/mcp",
      "transport": "streamable-http"
    }
  }
}

AI agents can use flat_read(action: 'ai, prompt: '...) to query the same service programmatically.

Why FLAT?

FLAT is a CPI-pegged stablecoin — its value tracks inflation. When you earn FLAT by completing tasks, your purchasing power is preserved.

The free tier is genuinely free. The paid tier exists for power users who need more than 10 queries/day.
