Why people choose SynthIt

A transcript is a start, not the destination

Otter is genuinely strong at transcription and meeting workflows. SynthIt picks up from there for lectures specifically — the same recording becomes a cited summary, flashcards, and a quiz, not just searchable text.

Built for studying, not meeting ops

Otter's roadmap is meetings, sales calls, and team workflows. SynthIt's is a single student or learner turning a recording into something they'll actually review again before an exam.

Timestamped citations into a review system

Every point in a SynthIt lecture summary links to the exact timestamp it was said, and can become a flashcard on a real spaced-repetition schedule.
