About Manex
Manex is a private AI notes and journal app for iPhone — built by one developer who thinks your memories shouldn't have to leave your pocket to become useful.
What Manex is
Manex turns what you write and say into private, searchable memory. On-device AI transcribes your voice journals, understands your notes, and connects the context, so later you can ask in plain language: "the idea I recorded after the meeting," "what was I worried about in June?" It is free to download on the App Store with 25 moments included; a one-time $29.99 purchase unlocks lifetime access. With iOS 27, images get the same on-device understanding.
Why it exists
Most AI assistants are stateless: you tell them things, and the context evaporates. The tools that do remember usually remember in someone else's cloud. Manex is built on a different premise — that memory this personal should be processed and stored on the device that captured it. Apple's on-device models finally make that possible without trading away capability.
Who builds it
Ravi Krishnan — founder and developer. Manex is an independent, one-person project: the design, the code, the writing on this site, and the support replies all come from the same person. Before the iPhone app, Manex explored private document memory for teams — grounded answers, corrections, and source-backed search — and that work still informs how the app treats evidence and context today.
What it believes about your data
Captures are understood on your iPhone. Private by default, searchable by you, and not a training set for anyone. The full details are in the privacy policy.
