Comparison

Silestis vs Notta

Two flexible transcribers — here's where Silestis goes further.

Notta is a capable general transcription tool: upload files or record, get text in many languages, with summaries and integrations.

Silestis covers the same core and then leans into turning audio and video into a searchable knowledge base: a browser extension that transcribes any web video, timestamped answers when you chat, semantic search across every recording, and study tools like notes, chapters, and flashcards — all EU-hosted.

Silestis is built to turn audio and video into a searchable knowledge base: ask questions and get answers with clickable [mm:ss] timestamps, search across every transcript at once, and generate notes, chapters, and flashcards for studying.
