trends101 is a free trend-intelligence dashboard for AI and tech. Every week it classifies ~1,400 Hacker News stories into 16 topic categories, measures topic-diversity (Shannon entropy) to spot when the conversation is narrowing, and correlates those signals with GitHub star velocity and PyPI download activity — so you can see which topics are actually gaining traction, not just which ones are loud. Includes an AI release timeline, influencer tracker...

Hey Product Hunt 👋
I'm Christian, a data scientist from Germany. I built trends101 for one selfish reason: I needed one monitor to hold my attention.
Since late 2022, AI has been a firehose — X threads, HN, Discord, papers, repo drops, podcasts. I kept three problems open at once: what shipped, what's actually being adopted, and who's driving the conversation. No single tool answered all three, so I started building one for myself.
What you can do on trends101:
Timeline — scroll the full history of AI model releases, papers, and milestones since Nov 2022.
Discover & Trends — see which AI topics are rising right now, week by week.
Entropy — a single chart that tells you when the Hacker News conversation is narrowing onto one thing (usually a sign something's about to break out).
GitHub — which repos are gaining stars fastest, tied to the topics that are actually being discussed.
PyPI — which Python packages people are installing, not just starring.
Influencers — who is driving each topic's signal.
Deep Analysis (LLM) — on-demand narrative summaries when you want the story behind the numbers.
Search — one search box across all of the above.
The data refreshes weekly. Open one tab in the morning, get the state of AI in under a minute.
It's free. No signup wall, no newsletter trap, no "premium tier coming soon." I'm shipping it because I wanted it to exist and because I'd rather get feedback than ad revenue.
Thanks for taking a look 🙏
