Why people choose SynthIt

Learning, not just collecting

Glasp is built for capturing and sharing what you read. SynthIt is built for the next step — turning the same source into something you actively study and remember.

A review system, not a highlight archive

Highlights are only useful if you revisit them. SynthIt turns a source directly into flashcards on a real spaced-repetition schedule, so review happens on a plan, not by chance.

One flat plan, no credit juggling

SynthIt Pro is one price for an unlimited library. Glasp's tiers are metered by monthly AI chat credits and transcription minutes on top of the subscription price.
