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

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

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

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

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.

Show HN: Date Time calulator with unique functions

Wed, 07/08/2026 - 9:44pm

I made a date time calculator tool with six different functions that I gave an old-school terminal-based look-n-feel. It has a few unique features that I have not seen on other similar web sites before. I have it try very hard to allow for a wide variety of inputs such as just a date or just a time; a three/four letter timezone, such as EDT or CEST as opposed to having to remember something like America/New_York (which it can also handle). Another unique feature would be adding or subtracting two durations. For example, adding 3 days 5 hours 14 minutes to 2 days 23 hours and 51 minutes. Another nice function is the ability to convert from one group of durations to another: 386 hours 24 minutes 36 seconds to just days hours minutes seconds.

There is also an example button for each function so that you can see how it works.

If you like find this useful, there is also a GitHub link to the CLI equivalent at the bottom of the page.
