Drafted with AI from the Nemos app and its documentation. Details about other apps can change, so check their sites.
Reflect is built around a daily note and links between ideas, with a clean feel and AI help for writing. It suits people who think on the page, most of all on a computer.
On a phone, most of what we do is catch things, not write. That is where Nemos differs. It takes a share from any app and keeps the preview. It reads words in screenshots on your device, records voice with transcripts, and shows reminders on your Lock Screen. It has a chat that answers from your library.
Notes in Nemos support images, links and checklists, and you can mention other items in a note with @. It does not offer a daily-notes method or a graph of backlinks in the way Reflect does.
Your library lives in your own iCloud, and Nemos has no web or Mac app, so it stays on your iPhone and iPad. When something else fits better: pick Reflect if writing and linking is your daily practice. Using both also works.
