What exists on Show HN

Built, still asked for92 Show HN launches do this job, and 13 more do part of it. People still ask, so the launches are missed, unknown, or not what they want. Ask what they’re missing before you build.

Instead of: Blinkist, ChatGPT

The idea, as matched

A tool that summarises long articles, newsletters, books or HN front-page stories into short, accurate TL;DRs that say what the piece is actually about, as a service, browser extension or app.

Jev first matched 29 requests to this idea; a second reader kept 24 of 29.

Every ask, newest first

Building this?

Read ten of the asks above first, because they say what the existing launches miss. If you ship it, post it as a Show HN so the next run of this list finds it.

Ship it like Vercel, on a server you own

This site runs on ShipTiffin. A push to GitHub deploys it, the way it would on Vercel, but the server is a Hetzner box in your own account. Postgres, sign-in, email, jobs and analytics are already on it, every project gets a hard limit, and nothing is billed by usage.

$19 a month per box, plus about $10 for the server at Hetzner. Open source, so you can also run it yourself for free.
