Tell me what to use

Build my AI stack.

Describe your case — or start from a real one below. The stack updates as you answer, every answer becomes part of a shareable link, and the decision copies out as a report. Drawn from the 112 tools already in the index; estimates are heuristic bands, not vendor quotes.

Start from a real case

01 — What are you building?
02 — Your case

How much does retrieval depend on filtering?

How often does the corpus change?

How fast must an answer come back?

03 — Constraints
04 — Priority

Answer what applies — nothing is required but the workload.

Your stack is drawn here.

Pick a workload, answer what applies, then press Build my stack. Requests per month sharpens the cost band; everything else narrows the picks.
