Valin

Valin is a private library for everything you save. Videos, posts, screenshots and PDFs go in from the share sheet, and the app reads the frames, transcribes the audio and pulls out names, quantities, timings and instructions from the text.

Search works by meaning, so you can describe what you remember rather than the exact title. Questions that need more than one item bring the relevant saves together, and each answer links back to the sources it used. Processing happens on your iPhone or iPad, and the library stays local unless you turn on iCloud sync.
