Fabius

Create your own AI agents, give each one its own instructions, tools and documents, then chat with them anywhere — your assistant, your rules.

Fabius lets you create your own AI agents and put them to work.

DESIGN YOUR AGENTS Give each agent its own personality, instructions, model, and tools. A research assistant, a writing partner, a support bot — you decide what each one knows and what it is allowed to do.

BRING YOUR KNOWLEDGE Upload documents and images, and your agents use them to give grounded, specific answers.

CONNECT YOUR CHANNELS Link a Telegram bot and your agent answers there too.

PRIVATE BY DESIGN No ads, no analytics, no tracking. Your conversations belong to you, and you can delete your account — and everything with it — anytime, right from Settings.
