Loved by Knowledge Workers

“Finally, all my ChatGPT research sessions are searchable. The rich content capture means code blocks actually look like code blocks.”

Sarah Chen

ML Engineer, Stripe

“I switched from Kortex because of the offline support. I work on flights constantly and NoteSync Pro just queues everything.”
