AI-powered usability feedback for your website, right in your browser
Run an AI assessment on the page you are viewing straight from the browser toolbar — no enrolment, scheduling or participant management required.
Feedback is written as concrete suggestions for layout, clarity and flow, so you can move straight from reading to editing.
The AI frames its critique around how your intended users would experience the page, rather than abstract design rules.
An optional sharper, humorous review style keeps repeated testing sessions from feeling dry.
Open-source workflow automation built for AI agents and technical teams
Build automations with a visual node editor, then insert JavaScript or Python code nodes when you need custom logic.
Connect to 500+ native services, any REST API via HTTP nodes, and any agent or coding assistant through MCP.
Run agents alongside regular steps, inspect every decision, and add structured inputs, guardrails and human approval steps.
Watch workflows execute live, open past runs, replay a run with mocked data and re-run just the step that failed.
