Ask HN: Would you pay to discuss a book with an official AI clone of its author?

Hacker News - Wed, 07/08/2026 - 10:46pm

When you're deep in a dense book, do you ever wish you could just ask the author something?

If each author had an official AI version of themselves, one they licensed and approved, trained on their books, talks, and interviews, with revenue going back to them and you could pay $15 per book to talk it through in a voice or video call while you read, would you try it?

I'm considering building this and want your opinion. Just asking if this interests people, like would you pay for that or at least try it free or would you just paste the book into ChatGPT for free?

Show HN: SlopWatch - A browser extension to rate webpages with AI content

Hacker News - Wed, 07/08/2026 - 10:41pm

Hey guys!

With an increase in AI-generated content (a.k.a "Slop"), I made a Chrome extension to help people identify it online.

It's sort of a like a rating system on how "slop"-y a page is, and you get to see other people's ratings to determine if the content is AI or not.

Go ahead and check it out on the Chrome Web Store, and let me know what you think!

Show HN: I mapped 8.5M research papers into interactive atlas

Hacker News - Wed, 07/08/2026 - 10:23pm

Reading a paper means opening a PDF, then hunting separately for the code, the citations, whether it replicated, and what genes/drugs it touches. I spent a few months trying to fix that.

Two parts:

1. The map: I embedded 8.5M papers (arXiv, PubMed Central, bioRxiv, medRxiv), ran UMAP to lay them out in 2D, and render them with a WebGL scatterplot. Every dot is a paper — click it for an LLM TLDR, key findings, citations, peer reviews (where they exist), and similar work. Zoom in and the clusters are labeled by topic.

2. Rich paper pages + an MCP server: each paper is rebuilt with linked genes/proteins/diseases/drugs (normalized to real IDs via PubTator, not regex), clinical trials, 3D structures, code, and a citation graph. It's all exposed as an MCP server too, so you can point Claude or an agent at 8.5M papers instead of pasting PDFs.

Stack: Next.js, Postgres (Neon), Cloudflare R2 for content, embeddings + UMAP/HDBSCAN for the map, a WebGL renderer. The hard part was the ingestion pipeline — 45+ heterogeneous sources normalized into one schema — and keeping entity links accurate, since papers use names not accession IDs (so curated link tables + PubTator beat regex every time).

Free, no signup to explore. I'd love feedback on the map UX and whether the TLDRs/entity links hold up for papers you know well.

Known limits: Google indexing is still slow so title-search isn't great yet, some older arXiv figures are missing, and peer-review coverage is partial.

Show HN: Python SDK for Content Integrity

Hacker News - Wed, 07/08/2026 - 9:51pm

I've been working on a Python SDK for signing and verifying digital content. Unlike traditional digital signatures, it's built around a revocable signature model using lease-based signing authority instead of conventional public/private key distribution. I'd love feedback on the API and whether the approach seems useful. Thanks.
