Ask. Automate.
Scrape.
RunLet is a browser copilot that lives in the side panel — not a new tab, not a desktop app. Three modes in one sidebar. It reads the page with you, clicks through flows on command, and pulls structured data without leaving the site.
Pull every product on this page into a table.

Built for people
who work in tabs.
Four shapes of user, one sidebar. Everything runs on the page you're already on — not in a new tab, not on someone else's server.
Developers
Complex web automation for engineering teams.
Business Analysts
Repetitive web operations, daily.
Business Owners
Daily process automation, no code.
AI Enthusiasts
Privacy-first alternatives to commercial tools.
One sidebar.
Three different jobs.
Ask the page.
Chat grounded in the tab you're on. Quote selections, drop screenshots, pull in a second tab, or route through MCP tools.
Run it, step by step.
Describe a task, approve each step. RunLet clicks, types, and waits — you see every action before it commits.
Extract, structured.
Point at a list page. Define the shape. Get a table, paginate through, export as CSV or send to a connected tool.

MCP — one WebSocket, any tool.
Run your local MCP host and RunLet picks up every tool it exposes. Scripts, file access, internal APIs — called from the side panel, approved per-step.
Integrations — Notion & Logseq.
Pipe summaries into your second brain. Notion (workspaces & parent pages), Logseq (local graph). More on the way — tell us which.
@-commands for the
things you do twice.
A snippet is a named prompt bound to a mode. Start typing @ in the side panel and they fuzzy-match. Edit inline, ship across devices.

Your pages stay on
your machine.
A built-in firewall gates which domains RunLet may read. Allow-list preferred, deny-list wins. Telemetry is opt-in and never touches page contents.
What runs locally
- Firewall allow / deny rules — stored in browser only
- Snippet library — synced, encrypted, recoverable
- MCP bridge — localhost WebSocket, no egress
- Chrome built-in AI (Nano) — fully on-device
- Page parsing + selection — never persisted
What we never collect
- Full URLs, page contents, selections
- Screenshots, recordings, form inputs
- Task instructions or prompts
- Logins, tokens, session cookies
- Anything a ToS wouldn't let us touch

Things people ask,
answered honestly.
How do the AI agents work together?
RunLet uses a multi-agent system. The Navigator handles web interactions — clicking, scrolling, typing. The Planner creates strategies, breaks down complex requests, and adjusts plans based on progress. The Validator ensures tasks completed correctly. These agents talk over Chrome's messaging APIs and collaborate on complex work.
Which browsers are supported?
RunLet officially supports Chrome and Microsoft Edge. It may run on Chromium-based browsers like Brave, Opera, or Arc — we recommend Chrome or Edge for guaranteed compatibility. Firefox and Safari are not supported today due to different extension architectures.
What is MCP (Model Context Protocol) support?
RunLet speaks the Model Context Protocol — an open standard for wiring AI agents to external tools. Connect databases, APIs, file systems, internal services. All connections run locally in your browser. Configure MCP servers from extension settings.
Will it work on sites behind a login?
Yes — that's half the point. RunLet uses your existing session. Gmail, Linear, internal dashboards, staging environments. The firewall lets you pin which of those it's allowed to touch.
