Bring your own AI to Musing. Pro Mode supports Perplexity, Anthropic, and OpenAI for cited web search on your API key—so you choose the provider and control costs.
Some ideas arrive half-formed — at a café in the rain, on a walk, the moment before sleep. Musing is built to catch them, and to give them back to you exactly when you need them.
You don't file. You don't sort. You don't tag. You just write — or speak — and move on. Later, you find any note the way you'd ask a friend: "What was that wine I liked?" "The café idea when it was raining."
FREE · PRIVATE · ON YOUR DEVICE
Musing is free — no ads, no account, no subscription, no credits. Capture, context, photos, and text search work on every supported device. Ask answers and semantic recall use Apple Intelligence on devices that support it — otherwise search stays useful without them. No server ever reads a note by default, nothing trains a model, and notes sync only through your own private iCloud — across iPhone, Apple Watch, and Mac.
SEARCH BY THE MOMENT
Every note quietly keeps its moment — neighborhood, weather, time of day, the kind of place. So you can ask by it: "coffee shop notes," "rainy day ideas," "notes from Traverse City," "late night notes" — or combined, "receipts from Oak Park last month." Instant, even offline.
JUST ASK
Search isn't a keyword box. Type what you're looking for in plain language and Musing surfaces the notes that match — even when you don't remember the exact words. Questions get answers grounded in your own notes, citing the notes they came from.
CATCH IT HOWEVER IT ARRIVES
Type a quick thought. On iPhone, speak a voice note — transcribed on-device; on Mac, dictate straight into the composer. Attach a photo and Musing reads what's there on your device — a receipt gets its total, a grocery list becomes a checklist. Check in to save a place. On iPhone: Home Screen widget, Siri, Shortcuts, Apple Watch, and the share sheet. On Mac: a menu-bar capture that never needs the main window, plus a Reading Room for asking and browsing.
YOUR PLACES
A quiet map of everywhere you've paused — most-visited spots and neighborhoods, on iPhone and in a dedicated Places window on Mac.
FIVE ROOMS TO WRITE IN
Choose how Musing feels. Foolscap, Inkwell, Verdant, Dusk, or Harbor. Light and dark work in every theme.
BRING YOUR OWN AI SERVICE
Connect your own Perplexity, Anthropic, or OpenAI API key in Pro Mode. You choose the provider, use your own account, and keep usage and costs under your control. Musing uses it only for web searches you request and returns cited sources alongside your note. Pro Mode is optional and is not a paid upgrade inside Musing; reading, organizing, and searching your notes otherwise stays on-device.
PRIVATE BY DESIGN
Sensitive places — clinics, hospitals, places of worship — are never named. Every context signal has an off switch.
NO FOLDERS. NO FEED. NO BUSYWORK.
Capture a half-formed idea. Find it later.
Free. Private. Yours.
i’ve honestly never found a good system for organizing my notes and this app makes it easy to not worry about organizing and just dump thoughts into it. It’s nice that it has different ways of looking at your notes and the search functionality let’s you just ask it what you were thinking about earlier and find the answer more intuitively.
Gets better with every release
It is ok, but
Great solution for quickly capturing my various ponderings. The Apple Watch integration pushes it into my everyday use. It now lives on my Watch home screen for voice notes.
Professional and easy to use

Onboarding was simple. The interface is professional. Looking forward to using it more
Love using it so far

Really easy to take quick notes, love that it fills in details with web search.
4.0.2 — Free, and fully on your iPhone (and Mac)
• Completely free. No limits, unlocks, credits, or account. If you bought an unlock before, there's nothing to do — everything is included for everyone now.
• By default, nothing goes to an AI provider. Earlier versions sent note text to Claude to answer questions; 4.0 handles note intelligence on-device and works in airplane mode.
• Ask, answers with citations, and reading your photos use Apple Intelligence, so those need a device that supports it. Capture, context, and text search work everywhere.
• Search by the moment: "coffee shop notes," "rainy day ideas," "notes from Traverse City," "late night notes."
• Photos read on-device — receipts get totals, lists become checklists.
• Bring your own AI service: Pro Mode supports Perplexity, Anthropic, and OpenAI for cited web search using your API key. You choose the provider and control its costs. Off by default; nothing is sold in Musing.
• Universal with Mac and Apple Watch — same private iCloud notebook.
Capture a thought. Find it later. That's still the whole app.
