PhiNote runs a language model right on your device — chat with your notes, generate quizzes, and get instant summaries with no internet connection, no cloud, no data leaving your phone.
Free to start · one-time unlock for AIMost note apps that offer AI send your writing to a server. PhiNote's language model lives on your phone — so your journal entries, meeting notes, and half-finished thoughts stay exactly where you left them.
The model runs locally. Turn on airplane mode and PhiNote's AI keeps working — there's simply no server to reach.
Ask questions across everything you've written and get answers grounded in your own notes — not the open internet.
Turn any note into a quick self-test — generated on-device, so studying works with no signal at all.
