Free YouTube Tools
Standalone utilities we build alongside the main summarizer — three run in the browser, three are Chrome extensions that work on the YouTube page itself. Each does one job well: no signup, no fluff.
AI Video Summarizer
The main toolThe utilities below handle raw materials — this one reads the whole video with AI and returns the key points with clickable timestamps. Free, 5/day, no signup to try.
YouTube Transcript Extractor
URL → full caption text
Paste any YouTube URL, get the full transcript as clean text — readable paragraphs or timestamps, export as TXT, SRT, VTT, or Markdown. Free to start, 5 extractions a day with a free account.
Timestamp Link Generator
URL + time → share link
Create a YouTube link that starts at an exact moment — share link, full link, or embed code. Understands 1:23:45, 90m, and plain seconds. Runs entirely in your browser, unlimited.
YouTube Comment Search
Chrome extension · search every comment
Search the comments of any video by word or by author — replies included. The panel loads the whole thread first, so a search covers all of it, not just what you scrolled past.
YouTube Comment Translate
Chrome extension · on-device translation
Brings back the translate button YouTube removed for many people — and runs it inside your browser, so comment text never reaches a server. 38 languages.
YouTube Chat Replay Search
Chrome extension · search a stream's chat
YouTube replays a stream's chat but cannot search it. Load the whole replay, find any message by word, user or Super Chat, and click to jump to that moment.
Thumbnail Downloader
URL → every resolution
Download any video's thumbnail in every resolution YouTube stores, HD 1280×720 included. Unavailable sizes are detected and hidden. In-browser, free, unlimited.
