Callis

An AI assistant that works around the clock and asks before anything important.

What it is

Callis is a personal assistant powered by AI. You connect your email, calendar and tools once, tell Calli what you want, and she plans it, reads what she needs, drafts the work and gets it done. Anything risky waits for your approval.

Why I built it

I wanted the kind of help a real assistant gives, without the setup. Most AI tools answer questions; I wanted one that finishes the job, runs all day on managed infrastructure, and stays in your control.

How it works

One thread, forever

Every request, plan, approval and result lives in one conversation, so Calli remembers context instead of starting over each time.

You stay in charge

Four trust levels (Trainee, Assistant, Partner, Executive) decide what Calli may do alone and what needs your OK. Approvals show up as cards you can approve, edit or decline.

Agents that do the homework

A planner breaks the request down, workers read documents and browse in sandboxed containers, and the results come back as finished drafts rather than suggestions.

Calli reflects real state

Her face is driven by what the system is actually doing: listening, thinking, researching, working, pleased, or waiting on you.

Production auth

argon2id passwords, short-lived access tokens with rotating refresh tokens and replay detection, and CSRF protection bound to the session.
