Extract the right signals
Keldura uses format-specific extraction paths for transcripts, document text, OCR, and video text.

Open the document view, inspect insights, generate cheatsheets, and ask cited questions across the folder.
Built for more than transcription
Bulk import turns raw material into a reusable workspace for research, support, learning, and agent workflows.
Many file types
Collect source material across videos, audio files, PDFs, slides, documents, websites, playlists, and channels.
Video text extraction
When a video shows slides or screen text, Keldura can sample the visual track so the library is not limited to the audio transcript.
Document view
Review imported videos and documents, inspect source insights, and move from a single document into the wider folder context.
Cited chat and cheatsheets
Ask grounded questions across imported sources and create cheatsheets that make the folder easier to reuse.
Bulk import FAQ
What can I bulk import into Keldura?
Keldura supports mixed source imports such as YouTube, websites, PDFs, documents, slides, audio, and video files, then organizes them into searchable folders.
Does Keldura use one extractor for every file type?
No. Keldura routes each source type to the extraction path that fits it, such as OCR for scanned documents, transcription for audio, and video text extraction for visible slide or screen text.
Can video imports capture text shown on the screen?
Yes. Video imports can combine audio transcription with sampled visual text, which helps capture slides, screen shares, and other text visible inside the video.
