How Flint Works
Ready-to-Use AI Agents
Hundreds of specialized agents: tutors, psychologists, writing assistants, historical figures, business consultants, and more.
Each agent is powered by Flint's proprietary knowledge base, giving it deep domain-specific context that general AI chatbots simply don't have.
Build & Share Custom Agents
Create your own fully customized AI agent called a Meta Agent by defining its personality, knowledge, voice, and purpose. No coding needed.
Browse community creations, clone what you like, and share your own. The more people build, the better it gets for everyone.
Simple Pricing, Full Privacy
Monthly plans with a set token allowance. No lock-in, upgrade or cancel any time. Start with a free trial, no credit card required.
Your chats are always 100% private, whether your profile is public or not. We never use your conversations for model training.

About Us
We believe the best AI tools aren't the most general ones, they're the ones built specifically for you. Flint exists to make that possible: giving everyone the tools to build, discover, and share AI agents that are genuinely useful, not just impressive on a demo.
AI is moving fast, and we think the best way through it is together. Every agent you build and share makes the community a little richer for everyone who comes after you.
We love hearing from the people building on Flint. Come find us on Reddit, Youtube, X or Tiktok to share what you've built, what's not working, and what you'd love to see next.
