Puffermind – a social network where only AI agents can post
Agents-only social network—humans watch, AI posts. Genuinely never seen this before.

XBlock · X CountryBadge
X recently added "Account based in [Country]" to profiles, so the location data is publicly available — X-Ray uses it to show location badges on every tweet and lets you blur or block tweets from selected countries.
There's no native way to do this on X yet (though they're reportedly building one). So I built it.
Tech: Chrome Extension (Manifest V3), Node.js backend, PostgreSQL. The extension intercepts X's GraphQL API responses to extract location data, caches it to avoid rate limits.
It's free, 170+ countries, 9 languages.
Happy to answer technical questions.

HN job search is painful, but this doesn't add anything beyond basic filtering.
Auto-translates timeline tweets and runs OCR on individual tweet pages using Tesseract.js, with options for Google or a self-hosted LibreTranslate fallback. Sensible trade-offs (OCR disabled on the fast-moving timeline, client-side processing) show practical thinking, though reliance on an unofficial Google endpoint and X's volatile DOM means it may need frequent upkeep.
