How to find public tenders in ChatGPT
ChatGPT is great at writing — but on its own it can't see today's live procurement notices. TenderB Stack fixes that: it connects a real, continuously updated public-procurement database to ChatGPT so you can ask for live tenders, contract awards and grants in plain English.
The short version
- Get a free API key at tenderstack.io/signup (your
sk_tdb_…key). - Open the TenderB Stack GPT in the ChatGPT GPT Store, or go straight to the TenderB Stack GPT.
- Paste your key when the GPT asks for it, then describe what you're looking for.
What you can ask
Because TenderB Stack uses semantic search, you don't need to memorise CPV or NAICS codes — describe the work in your own words and it matches on meaning, in any language:
- "Find open IT-services tenders in the Netherlands and Belgium published this month."
- "Show me below-threshold construction contracts in Germany under €200k."
- "Who has the UK NHS awarded cybersecurity contracts to since 2023, and for how much?"
- "Scout all US federal sources for zero-trust opportunities."
Why this beats copy-pasting links
A general model can summarise a tender you paste in, but it can't discover what's live today, can't rank results by fit to your business, and will happily invent a deadline or threshold if you let it. TenderB Stack returns real notices from official sources — TED, Find a Tender, Contracts Finder, TenderNed, BDA, oeffentlichevergabe.de, BOAMP and the US federal APIs — with AI summaries, plain-English matching tags, and who-won data where it's published. The dataset is over a million notices, refreshed every 8 hours, with history back to 2023.
Same key, more places
Your TenderB Stack key isn't locked to ChatGPT. The exact same key works in Claude via MCP and in the web app at app.tenderstack.io, so you can search wherever you happen to be working. Full setup details are in the documentation.
Set up a daily scout
Beyond one-off searches, you can save a profile once and ask "what's new for me?" any time — or get a daily email digest of new matching tenders. That turns ChatGPT from a search box into a standing procurement watch for your business.
