summarize.tech is down. Here is what to use instead.

The closest free like-for-like. Paste a YouTube URL, get a summary, pay nothing. That is the summarize.tech shape almost exactly, and for most people arriving here it is the right answer.

It handles long videos comfortably and you can follow up conversationally, which summarize.tech never allowed. What you lose is the clean chaptered format. Gemini's output is prose unless you ask it for timestamps, and its timestamps are less reliable than a purpose-built summarizer's.

The most feature-complete paid replacement, and the only tool here besides Taffy that acknowledges channels exist. Pro at $9/mo summarizes 2 channels and processes 5 videos at once; Unlimited at $19.92/mo raises that to 10 channels; Max at $69/mo to 20.

Read those channel numbers carefully, because they are the reason NoteGPT is not simply the answer to everything. "Summarize a channel" there means generating summaries across its videos, not building a searchable index you can ask questions against. And 2 channels on the entry tier is a low ceiling if channel research is your actual job.

Better than summarize.tech ever was at the thing it does, which is holding a set of sources you chose and reasoning across them. Its grounding is tight and citations point back into your source.

The mismatch is shape. You add sources one at a time, by URL, against a per-notebook cap. That is fine for six videos and a few PDFs. It is the wrong container for a channel with four hundred uploads, and raising the cap would not change that. It also never reads comments.

A browser extension that puts key ideas next to the video you are already watching, and the only tool on this list other than Taffy that reads comments at all. Its "Top Comment Overview" surfaces what viewers said about the one video open in front of you.

Worth knowing before you commit: eightify.app/pricing returned 404 on 21 August 2026, so pricing lives inside the extension after install. Third-party trackers cite roughly $4.99–$9.99/mo for Premium, but the figures disagree with each other and we could not confirm any of them at source. Install first, then decide.

A highlighter first, a summarizer second. Glasp is built around saving passages you chose from videos and articles, then revisiting them later, with a social layer showing what other people highlighted.

Prices went up on 1 May 2026: Pro from $12 to $15/mo, Unlimited from $30 to $36/mo, with a student discount still available on the Pro annual plan. If what you liked about summarize.tech was that it did the reading for you, Glasp is a philosophical mismatch. It assumes you are doing the reading and want to keep the good bits.

Serviceable when it works, and it is already open in a tab, which counts for something. Paste a URL and you will often get a decent summary.

The failure mode is quiet and worth naming. When it cannot retrieve the transcript it will sometimes produce a confident summary from the title, the description and whatever it already knows about the creator. That reads exactly like a real summary. For anything you plan to rely on, verify a claim against the video before you quote it.

A personal knowledge base that summarizes what you save and links it into a growing graph of your own material. Good if the summary was never the point and the remembering was.

It is the weakest fit on this list for a straight summarize.tech swap, because it is built around a library you curate over months, not a URL you paste once and forget. Pricing is corroborated from third-party trackers, not read at source.
