Keepframe
1. AI video summarizers
One-click tools that produce a short summary or a list of key points for a video. Great when you just need the gist before deciding whether to watch.
Honest comparison
Keepframe vs YouTube summarizers
There are great tools for getting value out of YouTube. They're built for different jobs. Here's how the main categories compare — and how to choose the one that fits how you learn.
The four approaches
Four ways people turn YouTube into knowledge.
2. Transcript-only tools
Tools focused on pulling the raw transcript out of a video so you can read, search or paste it elsewhere — often into your own AI chat.
3. AI research / notebook tools
You bring a video (or many sources) into a separate research or notebook app and ask questions across them. Powerful for multi-source research projects — at the cost of working outside YouTube.
4. Keepframe — a live learning sidebar
An AI companion that lives next to the YouTube player. Live concept cards appear while you watch, and the same panel holds the transcript, Study Brief, Study Notes and Full Summary — with .doc / PDF export. Built to learn during the video, not only after it.

Which tool fits the job?
Choose the workflow, not just the output.
Some tools solve one step. Keepframe stays with the video from the first idea to finished notes.
Choose a quick summarizer when…
You only need the gist, want to decide whether a video is worth your time, and do not plan to work with it further. Keepframe includes a concise Brief too, but it is designed to take you beyond the summary.
Choose a transcript tool when…
The raw text is the final result — for searching, quoting, or pasting into another AI. Keepframe includes the transcript inside the same learning workflow, alongside the context and materials built from it.
Choose an AI research workspace when…
Your project spans many sources — PDFs, documents, websites and several videos — and you need to explore all of them together in one research environment. That is a broader, multi-source job.
Choose Keepframe when…
You want the whole learning loop — understand the video as you watch, then keep what matters afterwards. Live concept cards explain key ideas in context, while the same sidebar gives you the transcript, Brief, Study Notes, Full Summary and export — one continuous workflow instead of separate tools.
Keep it in frame.
Watch it all. Take what matters most.
