AI Transcript Summarizer
Paste a meeting transcript, video captions or any long text — or upload a .txt or .srt file — and get a concise summary with key phrases and reading stats. Everything runs locally in your browser; nothing is uploaded.
How it works
- The text is split into sentences and cleaned (SRT timecodes and sequence numbers are removed automatically).
- Common filler words are ignored; each remaining word gets a score from its frequency in the text.
- Each sentence is scored by its word scores, with a small boost for the optional focus word.
- The top N sentences are returned in their original order so the summary still reads naturally.
Frequently asked questions
What does the AI Transcript Summarizer do?
It turns a long transcript into a short summary. It splits the text into sentences, scores each sentence by how many important words it contains, and shows the top-scoring sentences in their original order, together with key phrases and reading statistics.
Does it support SRT subtitle files?
Yes. You can upload a .txt or .srt file. SRT timecodes, sequence numbers and formatting tags are stripped automatically before the text is summarized.
How long can the transcript be?
It handles inputs from about 200 words up to 20,000 words. Very long transcripts are still processed entirely in your browser, though extremely large files may take a few seconds.
Is my transcript uploaded to a server?
No. The summarization runs 100 percent in your browser with JavaScript, so your transcript never leaves your device.
