I built something I desperately needed: daily AI audio lessons from real
developer trends (plus a Dutch coach for inburgering B1).
The hardest part wasn't the AI. It was figuring out how to score genuine
rising skills vs. one-day noise. I ended up building a cross-day momentum
signal that rewards skills accelerating over 3+ days and dampers spikes.
But I'm stuck on the next problem: how do you personalize this without
storing user data? (I'm privacy-first, so no subscriber DB — Telegram holds
the member list.)
If you've solved this, I'd love your take. And if you're learning Dutch +
coding, I'd appreciate you trying it and telling me what's useless.
What I'm curious about:
- Is the momentum signal actually working — am I surfacing real trends or just noise?
- Would the Dutch coach be useful for expat developers in NL, or is it too niche?
Technical details (for those who care):
• 7 sources: GitHub Trending, HN (Who-is-Hiring + front page), Stack Overflow
tag deltas, dev.to, Reddit, Lobste.rs
• Map-reduce skill extraction with deterministic attribution (corpus scan,
not LLM tally)
• Grounded briefs: reads actual source text via Jina + Exa, cited sources
• Delivered via Telegram (audio + PDF), Spotify podcast, email
• Privacy: PII redacted at ingestion, no subscriber data stored

(P.S. This is still beta — I'm looking for feedback, not users. If you try it,
tell me what's useless, not what's good.)
