YouTube transcript + AI summary + chat in one sidebar
“Captions/transcripts are junk” alone. sum.video pairs an integrated transcript with the summary — and 3 free chats a week — so you can ask follow-ups without leaving the video.
Auto-captions alone are often messy — useful as a raw dump, painful as a reading experience. The fix users ask for is not “more caption UI.” It is integrated transcript + summary: read the takeaways, then dive into the text when a sentence matters. Add chat for follow-ups and you stop alt-tabbing forever.
Why transcript-only tools frustrate people
A naked transcript:
- Has no hierarchy
- Buries the thesis under ums and tangents
- Makes “find the battery section” a Ctrl+F guessing game
Summaries without a transcript reverse the problem: you cannot verify a claim. sum.video keeps both in one panel on the watch page.
The sidebar trio
- Insights — structured takeaways
- Transcript — searchable source text
- Chat — ask “what did they say about X?” without rewatching
Landing page for the transcript angle: YouTube transcript and summary.
Chat quota honesty
Free: 3 chats per week (plus 3 summaries).
Pro: higher weekly chat allowance with unlimited text summaries.
We would rather show a clear weekly counter than surprise you mid-question. When free chat is used up, start a trial for more — same transparency as summaries.
Handling imperfect captions
If captions are junk on a specific upload:
- Still generate a summary for structure
- Treat proper nouns carefully — verify in the video via timestamps
- Prefer creator-uploaded transcripts when available
No tool can invent accurate speech from silence; when a video has no usable captions source, summarization may fail. Public videos with captions or transcripts are the sweet spot.
A research workflow
- Summarize.
- Ask chat one clarifying question.
- Jump to the timestamp chat points at.
- Copy the transcript line into your notes.
Professionals use this for meeting prep; students for lecture review; journalists for quote hunting.
Pricing reminder
Free forever at the weekly quota. Pro $59.99/year or $9.99/month after 7-day trial, with 10 audio/month if you also want listen mode.
Stop treating transcript and summary as separate apps
Install the extension, open a video you already half-watched, and keep transcript, summary, and chat in one place. That is the end of the copy-paste era for YouTube research.
Frequently asked questions
Does sum.video show the transcript with the summary?
Yes. The sidebar keeps transcript and summary together so you can search the text and still see structured insights.
What if YouTube captions are messy?
Auto-captions can be imperfect. The summary helps you see the main ideas anyway; use the transcript to verify wording when accuracy matters.
How does chat work?
Ask follow-up questions about the video in the same panel. Free users get 3 chats per week; Pro raises the weekly chat limit.
Do I need to download an SRT first?
No. We fetch the public transcript for you — no downloading a subtitle file first.
