About this app

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. WORK AS A TEAM Invite people to your workspace, give them a role, and choose who pays. 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.

What's new

Version 1.0.5 · Oct 17, 2026

WORKSPACES FOR YOUR TEAM Invite people to your workspace, choose their role, and decide who pays for it. DESCRIBE YOUR AGENT OUT LOUD Speak instead of typing in the agent builder. It now suggests the best match for the work you describe, starts from the tasks you asked for, and keeps your own words and rules in the agent it drafts. PAY YOUR WAY Use credits, or connect your own model key. Everything about paying is on one page. SMOOTHER CHAT Long conversations open where you left off and load older messages as you scroll. The keyboard no longer covers what you type. A NEW SIGN-IN Sign in with Apple, Google or email — with a one-time code if you prefer.
