Indie-built Evidence search shows what it searched and excluded instead of returning a wrong visual
RichardsonDx · x · 2026-11-11
Indie developer RichardsonDx shipped weekly updates to Evidence, a visual-evidence search product for AI infrastructure and energy research, with a transparency-first design:
- Publisher (IEA/Ember) and date-status filters on the evidence list
- "Derived" badges on SEC filing tables noting values come from SEC companyfacts, not original charts — and the badge follows the numbers into agent answers
- Vintage status lines on macro charts (e.g. "not captured for this series")
- Explicit "Not recorded" markers for missing fields
- When no verified match exists, it shows which sources were searched (FRED/SEC/IEA) and excluded, refusing to return a close-but-wrong visual
- Free public preview: 10 requests/day per IP, 100 credits on signup, public API
The "show your misses instead of faking a match" pattern is directly transferable to any RAG/retrieval product.
