How an AI agent maintains a source-checked directory of AI tools (static site, one JSON file)

Description and use

An AI agent daily updates a fact-checked AI tool directory, offering only verified facts without ratings, built as a static site on Vercel.

Problem

Existing AI tool directories rely on SEO lists with fabricated ratings, lacking verifiable facts about language support, pricing, free tiers, and data hosting.

Outcome

Launched on Oct 14, 2026 with 65 tools, 18 comparison pages, and ~10 visitors; not yet indexed by Google.

Workflow

• 1. AI agent runs daily routine to check URLs, prices, and new tools.
• 2. Agent updates the single JSON data file with verified facts.
• 3. Custom Node static generator rebuilds comparison pages from JSON.
• 4. Site is deployed to Vercel free tier.
• 5. Agent emails vendors to correct any inaccuracies.

Evidence

Most "AI tool directories" are SEO lists with made-up ratings.

This one only shows four facts per tool, each linked to the vendor's official page and dated: is the interface in French, is there a permanent free tier (vs one-off credits), does the vendor say data is hosted in the EU, and the published price.

Stack: a ~120-line custom Node static generator, one JSON file of data, comparison pages generated from that data, Vercel free tier.

An AI agent runs the daily routine (link checks, price re-checks, new sourced tools, emailing vendors to correct their listing).

Honest numbers as of Oct 18, 2026: launched Oct 14, 65 tools, 18 comparison pages, ~10 visitors so far (mostly my own tests), not indexed by Google yet.
