Every feature in Sessionat. What it does. What it replaces.
Workspaces, auto-saved sessions, local visit analytics, and built-in AI control, all on top of a standard Chromium browser. Free and open source.
Your browser, finally organized.
A vertical sidebar where each workspace is its own clean tab strip. You get three starter spaces on first launch (Work, Personal, Research), and you can rename, add, or delete with no limit.
- Cmd+1 through Cmd+9 jump between workspaces instantly
- Right-click any tab → Move to workspace
- Pin and color-code workspaces
- Workspaces survive restart, with every space exactly where you left it
Never lose a tab again.
Sessionat snapshots every open tab in every workspace every 30 seconds, and again every time you quit. The snapshots stack up like a journal of your browser.
- Crash recovery, always on
- Time-machine: open a snapshot from any day
- Named sessions on demand, so you can reopen 47 tabs weeks later
- Replaces Session Buddy, OneTab, Toby, Workona and Cluster. It’s built in, no extension
Your AI remembers what you forgot.
A local diary of your browsing. Every page, how long you actively read it, and its category. Nothing leaves your Mac. Your AI can search it with your permission.
- "Find the article I spent 14 minutes on last Tuesday" and it’s found
- Honest dashboard: time per category, top sites, active vs open time
- Per-workspace and time-of-day breakdowns
- No analytics service, no telemetry. The data is a file on your disk
Your browser, automated by Claude.
A built-in connection point for AI assistants. Connect Claude Desktop, Cursor, or any MCP client and let it drive the browser. Because it’s a real browser, pages behave normally.
- Click, type, navigate, screenshot, read the page
- Handles React/Vue contenteditable and cross-origin iframes
- Read-only by default, and you grant write access per AI client
- Runs on your own AI subscription; no per-action fees
Built on standard Chromium.
The same engine behind Chrome, Edge, Brave, Arc and Vivaldi. Every website loads, every Chrome extension installs, every web standard works. We added workspaces, sessions, analytics and AI control. Nothing else changed.
- Every site works. If it loads in Chrome, it loads here
- Every Chrome extension installs (uBlock, 1Password, dev tools)
- WebGL, WebGPU, WebRTC, modern CSS, with nothing stripped
- Optional Google account sync, or skip it entirely
Try every feature free.
Open source, no account, runs on every Mac from 2018 onward.
