Product overview
What Is Libraryminds?
Libraryminds turns videos you already watch into a private, searchable knowledge library. Find an idea by meaning, return to its exact timestamp, and reuse what you learned without rewatching hours of footage.
Timestamped transcripts from recorded sources
Search across your complete video library
Answers and summaries grounded in your content
From source to knowledge
Turn one recording into searchable evidence and reusable knowledge.
Conceptual illustration — not a product interface.
Libraryminds is an AI-powered video knowledge engine that transcribes supported video and audio — YouTube videos, podcasts, lectures, webinars, or meeting recordings — and makes completed transcripts searchable. Instead of rewatching footage to find one point, you ask a question in plain language and jump straight to the exact moment it's answered. Every video you add becomes part of a searchable knowledge library you own.
- Upload or import videos once
- Search across all your videos anytime
- Revisit exact moments without rewatching
- Build your personal video knowledge library
Think of it like a private Kindle for videos — everything searchable, organized, and retrievable when you need it.
Note: Despite the name, Libraryminds is not a book or document library. It is a personal search engine for videos you've already watched.
Some videos support asking questions using their transcripts. This does not create saved learning progress or long-term chat history.
How does Libraryminds work?
1
Add a video — upload a file, paste a YouTube link, or record directly in your browser.
2
AI transcribes it — speech is converted to timestamped text; speaker labels are available on Plus and higher plans.
3
It becomes searchable — search by keyword or by meaning across everything you've added.
4
Ask questions — get AI answers drawn from your own video library, with sources.
Who is Libraryminds For?

What Problems Does It Solve?
Forgetting What You Watched
Search your video library. Knowledge is no longer locked inside timelines.
Rewatching to Find Insights
Revisit exact moments. Stop scrubbing through hours to find one fact.
Notes That Don't Scale
Your videos become a searchable library. Better than bookmarks or saved links.
How is it different from a normal transcription tool?
A transcription tool gives you a text file and stops there. Libraryminds treats the transcript as the starting point: it builds a searchable library across all your videos, answers questions from your content, and helps you recall what you learned — not just read what was said.
Search Over Watching
You don't need to rewatch videos. You need to search them. Find exactly what you're looking for.
Recall Over Consumption
Build a personal knowledge library. Revisit only the moments that matter.
Ownership Over Passive Learning
If you can't search what you learned, you don't own it. Libraryminds treats videos like books.
Import from YouTube
Index what you've already watched. Search across your content without replaying hours. Save tutorials, lectures, courses, and long-form videos so you can search them later.
AI Semantic Search
Search by meaning, not just exact words. Find moments where a concept was discussed even if the speaker never used your exact phrase — powered by vector embeddings.
Chrome Extension
Transcribe YouTube, Vimeo, and TikTok videos in one click directly from your browser. No tab-switching, no file downloading — every transcript lands in your library automatically.
Business Workspace
Team plans include shared credit pools, seat-based billing, and a shared workspace where transcripts are available to members according to workspace permissions — not just the person who created them.
AI Meeting Bot
Provide an eligible Zoom, Google Meet, or Teams link. The bot attempts to join at the scheduled time, and after processing a searchable transcript appears in your workspace.
How much does Libraryminds cost?
Libraryminds has a free plan with 190 free transcription minutes — no credit card required. Paid plans (Plus, Pro, and Business for teams) add more minutes, translation, team workspaces, and automation. The developer API is available on every plan, including free.

Why Libraryminds Was Created
Aaditya Kumar, Founder of Libraryminds, experienced a common but overlooked problem.
While working a full-time job, he relied heavily on video content to learn new skills and grow professionally. But video-based learning came with a hidden cost — time.
Finding one useful insight often meant sitting through hours of content. Revisiting that same insight later meant rewatching everything again. And retention? Minimal.
The problem wasn't effort. The problem was the format.
Knowledge was locked inside videos — unsearchable, time-consuming, and hard to recall.
That's where the idea for Libraryminds began.
Libraryminds was built to remove three fundamental barriers to learning:
Time barrier
Stop rewatching entire videos. Search indexed transcripts and jump to the moment that matters.
Language barrier
Access and read knowledge in your preferred language, regardless of the original content.
Cost barrier
Built for students, creators, and professionals — with pricing designed to stay accessible.
Libraryminds is not about watching more. It's about understanding faster, recalling better, and accessing knowledge on demand.
No hype. No unnecessary complexity. Just a better way to learn from video.
