The browser that thinks alongside you.

Mind Browser is a full Chromium browser with five autonomous agents living in the sidebar. It reads the page, runs the task, and hands you the result — using your models, on your machine.

One browser.
Five specialists.

Give it a sentence. The Planner breaks it into steps, the Navigator drives real tabs — clicking, typing, scrolling — and the rest read, write and reason on the pages you're already looking at.

01

Planner

Turns "find the three cheapest flights and put them in a note" into an ordered plan, then refines it as reality pushes back.

02

Navigator

Actually drives the browser. Opens pages, scans interactive elements, clicks, types, switches tabs — and reports what really happened.

03

Researcher

Fans out across sources, pulls full article text instead of snippets, and keeps the citations attached to the claims.

04

Writer

Drafts, rewrites and proofreads in place — in a doc, a text box, or straight into Notes without leaving the tab.

05

Analyst

Reads tables, filings and charts, compares open tabs against each other, and tells you what changed.

Every step is real

No fire-and-forget tool calls. If an agent says it read a page, the page text came back with it — so the next step reasons on facts, not hope.

The things you open twelve tabs for are already here — and they load in milliseconds because they're native pages, not websites.

News Hub

Headlines by section and by country, live search trends, and prediction-market odds from Polymarket and Kalshi — side by side, keyless, no account. Open a story and the AI panel already has the full text.

Finance Hub

Live quotes and charts from 1 day to max, with moving averages and Bollinger bands already warmed up at the left edge — it fetches more history than it draws, so the indicators are correct from the first pixel. Plus trending tickers, a watchlist, and news filtered to the industry you're actually holding. Keyless, like everything else here.

New Tab, alive

4K wallpaper that changes daily, real weather, a clock you can theme, notes and headlines in one glance.

Shields

Network-level blocking of ads, trackers and fingerprinters — on by default, per-site toggle in the address bar.

0trackers blocked here

Notes that follow the page

Highlight anything, send it to Notes with the source attached. Jot on the new tab page and it's already saved — everything stays in a plain folder on your disk.

Split View

Two live tabs, one window, ⌘\. Ask the AI to compare them and it reads both.

Command Palette

⌘K for every tab, bookmark, setting and action you've ever touched.

Your extensions

Installs straight from the Chrome Web Store. Password managers, uBlock, the ones you already trust.

Bring your own brain

Your keys.
Your models.

Point each agent at a different model — a fast one for navigation, a strong one for planning. Or run the whole thing offline through Ollama and send nothing anywhere. There is no Mind Browser server in the middle, because there is no Mind Browser server.

Privacy

Nothing phones home.
Not even us.

No telemetry

No analytics SDK, no crash pings, no account. History, notes and chats live in a folder on your own machine that you can open, back up, or delete.

Blocking by default

Ad, tracker and fingerprinting domains are dropped at the network layer before a single request leaves — every tab, every webview, every extension.

Bring your own VPN

Route all traffic through a SOCKS5 or HTTP proxy you control — your VPN endpoint, an SSH tunnel, Tor. Deliberately not a bundled service: we'd rather never touch your traffic than promise not to look.

Local-only mode

With Ollama selected, prompts and page text never leave the machine. The agent loop runs the same either way.

Muscle memory

Fast hands welcome.
