A second brain that remembers everything and files nothing. Capture the spark — a fleeting line, a photo, a voice memo — then forget it. When you need it back, just ask in plain words, the way you'd ask your own memory.
Download on theApp StoreMost “second brain” apps quietly turn you into a librarian — folders, tags, backlinks, a system to maintain. Creatives don't want to file; they want to think. Musing throws all of that out. Capture the thought and let it go. When it matters again, just ask.
Flip on Web Search as you write, and Musing researches your note on the live web — it even reads a photo you snapped, like a book cover, and folds the real details right into the note, sources included.
Uses one AI search credit. Everyday notes stay free and unlimited.
Capture in a tap, find by asking, and a quiet record of where each note happened.
Messy, mid-sentence, at the worst possible moment. Musing catches them, holds the context, and gives them back the instant you ask.
Type, talk, or snap a photo. Voice notes keep the actual audio, not just the transcript — and the cleanup keeps your voice, so a half-formed line stays a half-formed line.
No folders, no tags, no sorting. Every note quietly remembers its context at capture — place, time, weather — so you find things later by simply asking.
“What was that café idea when it was raining?” Ask in plain language and Claude finds the notes that match — ranked by relevance, even when you don’t recall the exact words.
Attach an image and Claude reads the text and names what’s in it — a plant, a landmark, a dish — folded right into the note, and fully searchable.
A Home Screen widget, three Siri phrases, the Shortcuts app, and the share sheet — so a thought is never more than a tap or a word away.
Notes are stored on your device and backed up to your private iCloud. AI runs through Anthropic’s Claude. Nothing is ever sold, and nothing is used to train models.
Capturing notes is always free and unlimited. You only pay for AI search — and only if you want more. Buy once; credits never expire.
Credit packs are one-time purchases billed through the App Store — no subscription, no recurring charges, ever. Credits don't expire.
