FAQ

FAQ

Answers to common questions about saving content, indexing transcripts, and upcoming PDF annotation support.

Do you support saving X bookmarks, likes, and retweets?

Yes. Memex lets you save X bookmarks, likes, and retweets through the browser extension, and support in the mobile app is coming soon.

Do you index YouTube video transcripts?

Yes. Whenever you add a YouTube video link to Memex, we index the transcript and make both the video and its cover image searchable.

Do you index TikTok video transcripts?

Yes. Memex transcribes TikTok videos and indexes both the cover image and the full transcript so everything is searchable.

Do you support annotating PDFs?

Not yet. PDF highlighting is coming soon, and you'll be able to use those highlights in search and AI workflows.
