Chat-first, orb at the centre
The whole product is one conversation with a living orb that breathes with the work — idle, listening, thinking, speaking — so you always know what your agent is doing.
Kavvo v1 · Free & open source
An AI agent that learns the job, then does it.
Kavvo is a skill-first AI agent that lives in chat. Talk or type — it listens, thinks, browses, remembers, and quietly creates its own skills in the background so it gets better at your work every day. You bring the API keys; Kavvo brings the agent.
Free forever · Bring your own API key · Runs on your machine or your server
What Kavvo does
One agent, everything in reach
No plugin stores to browse, no prompt gymnastics. Kavvo is built around a single conversation — everything else happens around it.
Voice that actually converses
A real listen → think → speak flow. Start talking and Kavvo listens; it thinks in the open, then speaks back. Interrupt it mid-sentence and it stops and listens again.
A real browser in its hands
Kavvo drives a real-human browser — opening pages, reading them, filling forms, and attaching to your own browser session when a task needs your logins.
Memory with a constitution
Long-term memory keeps your projects, preferences and facts straight across sessions — guided by a constitution you write and can edit any time.
Automations that brief you
Morning briefings, weekly reviews, overnight delegations. Kavvo prepares the summary before you ask, and reports what it did while you were away.
A live activity stream
Every action — a page opened, a skill written, a memory saved — streams into a live feed beside the chat. Nothing happens off-screen or without a trace.
How it works
From key to conversation in three steps
1
Connect your key
Paste an API key from a model provider you already use. The key stays on your machine or server and talks to the provider directly — Kavvo never sits in the middle.
2
Pick a model — or Auto
Kavvo fetches the provider's real, current model list automatically. Choose the exact model you want, or leave it on Auto and let Kavvo route each job sensibly.
3
Just talk
Type or speak like you would to a sharp colleague. Kavvo plans, browses, remembers, and builds the skills it needs — then shows you everything it did.
Background skills
It writes its own skills. You never manage a menu.
Most AI tools hand you a store of add-ons to install and babysit. Kavvo works the other way: when a task needs a capability it doesn't have, it creates that skill itself, keeps it in the background, and reuses it next time. Your only job is the conversation.
- Skills are created automatically when a task calls for them
- They persist, improve, and combine across sessions
- No store, no installs, no settings maze — ever
You ask once"Every Monday, pull my sales numbers into a summary."

Privacy guardian
Your keys. Your memory. Your call.
Kavvo is bring-your-own-key by design: your provider keys stay on your machine or server, and your conversations go to the provider you chose — not to us. And when something should not be remembered, the privacy guardian can purge a whole topic from memory and hand you a receipt of exactly what was removed.
- Keys stored locally, used only to call your provider
- Purge any topic from memory — with a written receipt
- Secrets are scanned before anything is shared outward
- Open source: read every line that handles your data
Topic purged: "old address"
Provider key used locally · never uploaded
Outbound share scanned for secrets
Memory export ready whenever you want it
Pricing
Free software. Your keys, your costs.
Kavvo itself costs nothing. You pay only your model provider, directly, for the tokens you actually use — no markups, no seats, no tiers of features held hostage.

FAQ
Straight answers
Is Kavvo really free?
Yes. The Kavvo app is free and open source under the MIT License — download it, run it, read the code, change it. The only cost in the picture is your own model usage: because Kavvo is bring-your-own-key, your provider bills you directly for tokens, at their prices, with nothing added by us.
Which AI models can I use with it?
Any model from a provider whose API key you connect. When you add a key, Kavvo fetches that provider's real, current model list automatically — you pick the exact model you want for a chat, or choose Auto and let Kavvo decide per task. Switch models any time; your memory and skills carry over.
Where do my API keys and data live?
On the machine or server where you run Kavvo. Keys are used locally to call your provider directly — they are never sent to us, and there is no Kavvo account required to run the app. Memory also lives with your install, under your control, and can be exported or purged.
What exactly is a "skill"?
A skill is a capability Kavvo writes for itself when a task needs one — a repeatable way of doing something, saved and reused. Unlike plugin stores, skills are background machinery: Kavvo creates, tests and improves them on its own. You will see them mentioned in the activity stream, but you never install or manage them.
Can Kavvo forget something it remembered?
Yes — that is the privacy guardian's job. Tell Kavvo to purge a topic and it removes that material from its memory and gives you a receipt listing what was deleted, so "forgotten" is verifiable rather than a promise.
Do I need a server, or can I just try it?
Both. A public preview instance runs at the "Open Kavvo" link — open it, connect a key, and talk. For keeps, run Kavvo on your own computer with the Windows bundle, or on any small server you control. A managed hosted tier is planned for later.
