A second brain for creative minds
✦ AI-powered  ·  Web Search  ·  No subscription

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.

A second brain you never have to file

Most “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.

Remembers everything Every idea, photo, and voice memo — held with the place, time, and moment it arrived.
Files nothing No folders, no tags, no upkeep. The organizing happens invisibly, so you never do it.
Recalls on demand Ask a question and Claude surfaces the note you mean — even when you've forgotten the words.

Now your notes can look things up

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.

  • Snap a book cover, write “add details about this” — get the author, year, and facts back
  • Works from what you type, a photo, or both
  • The findings become part of the note — searchable and shareable

Uses one AI search credit. Everyday notes stay free and unlimited.

A brain built for the way ideas actually arrive

Messy, mid-sentence, at the worst possible moment. Musing catches them, holds the context, and gives them back the instant you ask.

Capture anything, instantly

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.

Never organize again

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.

Find it by 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.

Reads your photos

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.

Capture from anywhere

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.

Private by design

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.
