Anything else

Countries, real estate, restaurants, research papers — just describe what you need

How is this different from Clay?

Clay connects to 150+ verified data providers (Apollo, ZoomInfo, Clearbit, etc.) for structured lookups. OpenClay takes a different approach: it uses AI + live web search to research each row — more like Clay's Claygent feature. This means:

  • Great for public info, news, general research, company overviews, anything Google can find
  • Great for custom research questions that don't fit into rigid data provider schemas
  • Not ideal for verified contact emails, phone numbers, or data that requires proprietary database access

Built OpenClay because data enrichment shouldn't cost $150/month. If you find it useful, I'd love to hear from you.

FAQ

Frequently asked questions

What is OpenClay?
OpenClay is a free, open-source alternative to Clay.com for AI-powered spreadsheet data enrichment. It uses AI models (Claude or Gemini) combined with live web search to research and enrich each row of your spreadsheet — finding company data, contacts, news, and any custom information you describe.
Is OpenClay really free?

Yes. OpenClay is privacy-first by design. Your files are parsed entirely in your browser — never uploaded to any server. Your API key is stored in browser memory only (React useState) and is never persisted. There is no database, no cookies, and no localStorage. The entire codebase is open source so you can verify these claims.
What AI models does OpenClay support?
OpenClay supports Anthropic Claude (Haiku 4.5, Sonnet 4.5, Opus 4.5) and Google Gemini (2.0 Flash, 2.5 Flash, 2.5 Pro). All models include live web search capability for up-to-date research results.
What file formats does OpenClay support?
OpenClay supports CSV (.csv), Excel (.xlsx), and legacy Excel (.xls) files up to 10MB. Files are parsed entirely in your browser using PapaParse and SheetJS — nothing is uploaded to any server.
Do I need to create an account?
No. OpenClay requires no account, no sign-up, and no credit card. Just open the app, upload a spreadsheet, add your AI API key, and start enriching. Your key stays in browser memory and is never stored.
What kind of data can I enrich?
Anything you can describe in plain English. Common use cases include company research (CEO, funding, employee count), lead enrichment (job title, LinkedIn, recent news), university data (ranking, tuition, acceptance rate), product research (pricing, reviews, competitors), and more. OpenClay works for any dataset — not just B2B sales.
