I built a Mac notes app with Jarvis inside

I kept losing ideas on my Mac.

Not because I lacked notes apps. Because every notes app wanted a window. By the time it finished opening, the thought was already gone — replaced by Slack, a browser tab, or whatever I was supposed to be doing.

I didn't want to abandon notes. I wanted better notes — always nearby, out of the way until I reached for them — and then I wanted something smarter living inside those notes: an agent that could see my screen, hear me, talk back, and act in my apps.

So I built Tucky: a native macOS notes taker that docks to the edge of your screen, with a Jarvis-style agent inside.

Site: tucky.io

Notes first

Tucky is a notes app.

Notes sleep as a thin stripe on the side of your screen. Reach over — titles fan out. Open one, write, tuck it away. They're local files, encrypted on disk. Checkbox tasks, live Markdown, global shortcuts, clean exports. Core note-taking works without sending your life to the cloud.

That edge UI is the whole point of the free experience. Sticky thoughts finally have a home that doesn't demand a full window.

Jarvis inside

On top of the notes — not instead of them — sits the agent.

Hold ⌥Space from any app and talk to Tucky. From the notes edge, it can:

See the screen — e.g. "summarize this course" → looks at what's on screen, summarizes, drops it into a note
Hear and talk — voice in, voice out
Triage email — "Any news? Check my emails" → reads Gmail, pulls what matters, tells you
Act through connectors — Gmail (read/send), Google Docs, Sheets, Calendar, Notion, GitHub, with more coming

The notes stay the durable surface. Summaries land in notes. Thoughts stay in notes. The agent is how you capture and act faster — Jarvis inside the notes app, not a separate chat product wearing a notes costume.

Privacy detail I care about: when you ask about a note, titles can go with the question; the body only goes to the model if you allow a read.

The problem this combo solves

Founders (me included) don't only have a "chat with AI" problem. We have a capture problem and an action problem.

Plain sticky notes capture, but they don't act
Browser AIs act (sort of), but they don't live on your desktop or keep a local encrypted scratchpad
Big knowledge apps are workspaces — great later, heavy when the idea is still a half-sentence

Tucky's bet: edge notes for capture, agent inside for action.

Build decisions

Native Swift, not Electron

Swift / SwiftUI / AppKit. About 15 MB. macOS 15+, Apple silicon and Intel. Updates itself.

An always-present edge UI has to stay light or people quit in a week. Native was the honest choice.

Edge UI instead of a window

Windows demand attention. The edge doesn't: stay invisible → fan out → collapse. If the notes UI is loud, you rebuild the context-switch problem you were escaping.

Local notes, optional agent brain

I'm not going to pretend Plus AI runs entirely offline. Notes are local-first and encrypted. The agent uses models when you're on Plus. Try the notes for free; pay when you want Jarvis inside.

Pricing


Free	Notes on the Mac (limited free notes). No agent, no voice agent, no connectors.
Plus	$4/mo — unlimited notes (still local/encrypted), models, voice (60+ languages), connectors.

Notes free so anyone can try the edge. Agent at $4/mo when you want the Jarvis layer.

Launch snapshot (honest)

I started Tucky alone, for my own chaos. We're now a team of about four.

In September 2026 we launched on Product Hunt and hit #2 Product of the Day. Surreal — and temporary. The spike fades. What remains is whether people open the edge notes every day, and whether the agent inside earns the $4.

If you've grown a native Mac notes utility past week one, I'd love to hear what actually worked.

What's next

More connectors. Clearer demos of "notes + agent": screen → note, email → spoken brief, Notion/Docs actions. Messaging that stays honest: notes taker with Jarvis inside — not "AI chatbot, but Mac."

(There's an unrelated wearable thermometer also called Tucky online. Search macOS or go to tucky.io.)

Try the notes / meet the agent

→ tucky.io

Start with free edge notes. If you turn on the agent, tell me what felt magical, what felt wrong, and what it should do next.

I'm building in public. Feedback > applause.

Native Swift on macOS. Direct download (not on the Mac App Store yet). Made by Mehdi Harzallah and a small team.

We hit #3 Product of the Day on Product Hunt 🏆
