Why it's different

Every other AI forgets you.
JarvAI remembers and acts.

Chatbots start from zero every conversation and stop at giving you words. JarvAI keeps a permanent, private memory of your world, and can act on it through your own accounts. That's the whole game.

Persistent memory

A second brain that compounds.

Every note, project, person, decision and meeting gets written into a personal knowledge base that lives on your machine, and never resets between chats. JarvAI learns how you work and what you're building, so its answers stop being generic and start being yours. The longer you use it, the sharper it gets.

A private wiki of your life, built as you go
Pulls the right context automatically, with sources
Grows every day instead of forgetting every session

It's all local. Your brain is encrypted on your own disk. Never uploaded, never trained on, never ours.

The Vault & autonomy

It doesn't just answer. It does the work.

Save your logins and keys in JarvAI's encrypted Vault and it can actually operate your accounts: triage the inbox, build your schedule, run automations overnight, file the meeting notes. It reasons over your brain, uses your credentials, and takes real action. That's the difference between an assistant that talks and one that gets things done.

An encrypted Vault for your credentials, unlocked only for you
Runs real tasks through your own accounts, even unattended
Every sensitive move asks first; you stay in command

Credentials never leave your device's keychain, and nothing sensitive happens without your say-so.

What it does

One app that thinks with you
and gets things done.

The Brain

Your knowledge, alive.

Everything you capture (notes, projects, people, goals) becomes a living map that converges on you. Ask your brain anything and JarvAI answers from what it actually knows, with sources.

Living constellation of your work
Instant recall across everything
Grows sharper the more you use it

Chat that acts

A chief of staff, not a chatbot.

JarvAI reads your brain, uses your connectors, and takes real action: drafting the email, building the schedule, filing the note. Every sensitive move asks first, so you stay in command.

Automations & Daily Brief

It wakes up and does the work.

Describe a routine in plain English and JarvAI designs the automation for you. It runs on a schedule in the background, starting with a morning brief built from your calendar, inbox, and open threads.

Meetings

Never take meeting notes again.

Capture any call (Zoom, Teams, Meet) with no per-app setup. Audio is transcribed locally on your machine, then JarvAI writes the summary and action items straight into your brain.

How it works

Up and running in minutes.

No setup rabbit holes. Three steps and JarvAI knows your world.

01

Connect Claude

Sign in with your Claude account right inside the app: no terminal, no API keys, no extra bill. JarvAI runs on the subscription you already have.
02

Connect your world

One click links Gmail, Calendar and Tasks. JarvAI interviews you for a few minutes and writes your personal brain: who you are, what matters, what you’re working on.
03

Think & act

Chat with it, set it loose on automations, capture your meetings. JarvAI reasons over your brain and takes action through your accounts, asking before anything sensitive.

Make it yours

Four themes. One soul.

Re-skin the entire app in a click, from warm molten dark to cool electric blue to a bright paper daylight. The ember at the core stays, whichever mood you’re in.

The details

Built like a tool you’ll trust
with your whole life.

Every decision here favors your privacy, your control, and your time: the quiet things that make software feel expensive to use.

Private & local-first

Your brain is a folder of files on your own machine. Secrets are encrypted with your OS keystore. Nothing trains anyone else’s model.

Runs on your Claude

No second AI bill. JarvAI rides your existing Claude subscription and works with the frontier models you already pay for.

One-click connectors

Connect Google in a single click: Gmail, Calendar, Tasks. Add any MCP server for everything else.

Customizable dashboard

Drag-and-drop widgets for your calendar, inbox, to-dos, goals, usage, and a live mind-map of your brain.

Built-in secure vault

Store credentials encrypted on disk. JarvAI asks for permission every single time before it ever reads one.

Instant brain search

Full-text retrieval across every note, the moment you write it, so answers are always grounded in your work.

Four beautiful themes

Molten, Midnight, Daylight, and Azure. The whole app re-skins in a click while the ember core stays home.

Contacts & people

Import your contacts into rich people pages so JarvAI knows who’s who across your notes and meetings.

I wanted an assistant that actually knew me (my work, my projects, my goals) and could act on all of it without shipping my life to someone else’s cloud. Nothing did that. So I built JarvAI: a second brain that lives on your machine, runs on the AI you already pay for, and works like the chief of staff I always wanted.

Questions

Good questions,
honest answers.

Still curious? Email us and ask us anything.

What exactly is JarvAI?

A private desktop app that turns your notes, projects, and accounts into a second brain an AI can think with and act on. It’s the “Jarvis” idea, made real and yours.

Do I need a Claude subscription?

Yes. JarvAI runs on your own Claude account, so there’s no separate AI bill and your usage stays yours. You bring the intelligence; JarvAI gives it your memory, your tools, and a place to live.

Is my data actually private?

Your brain is a folder of plain files on your own machine, with credentials encrypted by your OS keystore. Nothing is uploaded to us and nothing is used to train a model. Meetings are even transcribed locally.

What can it really do for me?

Search and reason over everything you know, draft emails, build your schedule from your inbox, run automations on a schedule, and capture meetings into your brain, acting through your connected accounts, always asking before anything sensitive.

Which platforms are supported?

Windows and macOS, both available today. Each ships a one-click installer that keeps itself updated. The Windows build is code-signed; on macOS you may need to right-click and choose Open the first time, while we finish Apple notarization.

Is it available now, and what does it cost?

Yes, it’s available today. Personal is $15/mo or $144/yr, and Pro is $29/mo or $288/yr, with custom builds for teams quoted individually. Every plan runs on your own Claude subscription. Subscriptions renew until you cancel, you can cancel anytime, and there’s a full refund within 14 days if it isn’t for you.
