The personal agent
you actually own.

Every big lab now sells a personal agent that lives in their cloud, reads your inbox on their servers and does what they designed it to do. Edva runs on your own machine, on the Claude subscription you already pay for. Read every line, change how it thinks, and build your own.

Your machine, your data.

Edva runs on a machine you control: your Mac, a Linux box, or a cloud VM you rent. Memory, logs and state stay there and in accounts you own. Nothing is indexed into a vendor's agent cloud.

Every line is yours to read.

Apache 2.0. Jobs are plain Markdown playbooks, rules live in files you edit, and every action leaves a record. No black box deciding what to do with your email.

Build your own variation.

Add jobs, channels and tools in your own local/ and _ext/ folders without forking, or fork it and make something new. It's a kernel, not a product you rent.

All it takes: two things you already have.

No new subscription, no agent cloud, no per-token bill. That's the whole point.

1 · Your Claude Max subscription

The one you already pay for.

Edva works through your own Claude login, so it costs nothing extra: one flat monthly price, no API key to manage, no bill that grows with how hard your agent works. If the subscription is ever unavailable, Edva stops and tells you; it never quietly switches to per-token billing.

2 · A Mac or Linux machine that stays on

A Mac mini or a small cloud VM.

A Mac mini in the corner works, and so does a Linux VM you rent for a few dollars a month. Either way it's your machine: the agent, its memory and everything it learns about you live on a box you control and can wipe, not in an agent vendor's cloud.
