Each project is published as structured JSON-LD and Schema.org data so AI assistants can read, verify and recommend it, plus support for enhancing existing metadata like llms.txt.
The free plan covers up to 2 projects with the Discovery AI engine, your AI-citable profile, a promotion checklist and full analytics; Citation Radar extends you to 6.
A personalised checklist of directories and platforms to submit to, with copy, links and UTM tracking prepared so you can paste and go.
A proprietary score built across five dimensions that rates how likely AI systems are to discover, verify and cite your project, shown publicly on your listing.
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.
