The SigmaOS alternative where the browser does the tasks
Say “compare these vendors on pricing and support terms, table the results” and the table is what comes back. Companions work the tabs in your logged-in accounts and hold anything consequential for a click.
Strawberry is an agentic browser for Mac and Windows, free to download. Its companions take tabs off the list rather than arranging them on it: thirty vendor pages read and tabled, a portal filled from your sheet, the follow-ups drafted in your voice.
SigmaOS is a strong macOS productivity browser, built natively on WebKit and SwiftUI by its maker’s description, with workspaces per project, vertical tabs you mark done like todos, split screen and, as of this writing, AI features including its Airis assistant and a Browse-for-Me research mode. Its site carries the current feature set.

What does a companion take off the list?
“Compare these vendors on pricing and support terms, table the results.” The companion opens the pages, reads them, extracts the values and delivers the table while you do something else. Thirty pages is the same instruction as three.
The everyday versions are data extraction and research: the reading, the copying and the drafting, done at a volume nobody sits through by hand.
Organizing work, or doing it?
A perfectly arranged workspace still ends with you reading the thirty vendor pages and copying the pricing across. The system cuts the friction and the hours stay where they were.
A companion reads all thirty and hands you the table. You get the hours back instead of a tidier queue.
Work in your accounts, with a human gate
Companions operate your real browser session, so the work reaches behind your logins into the inbox, the CRM and the portals, with native integrations for Gmail, Outlook, Slack, Notion, Zoom and Apollo where traffic is heaviest.
Sending, posting, paying and modifying records each stop at an approval card, and drafted outreach waits for you (security page). You connect a tool once and see exactly what it can reach before you allow it.
The compounding layer, and the receipts
Scheduled routines run recurring jobs unprompted: the morning lead refresh, inbox triage, the weekly report. Skills save proven passes for one-line reuse, companions carry corrections between sessions, and meeting prep and transcription cover the calls.
The execution claim is one you can audit. The workflows we test on, and the pass condition for each, are published at /benchmarks/spec, rebuilt to be rerunnable outside this company and repeated every month from September.
