Speak your note.
AI organizes it.
Just talk — tagging included. Simple Memo's AI understands your memo, adds a title, tags, and a type, then delivers it to your inbox and Obsidian. The tagging happens on your iPhone; sending the email needs a connection.
- Fully on-device AI
- Nothing sent out for tagging
- Automatic fallback on older devices
Kill the “I'll organize it later” pile
Capturing a note takes a second — organizing it never happens. AI auto-tagging finishes the organizing while your memo is being sent. All you do is talk (or type).
Just speak
AI transcribesTap the mic and talk (with “Auto-start voice input on launch” on, the app tries to start listening when it opens). Fully on-device voice auto-input on iOS 26 or later turns speech into text — fast and private. Works from your wrist on Apple Watch too.
Tags, added for you
AI understands the content1–3 tags that describe your note, a concise title, and a type — to-do, idea, or log — detected automatically. Your original text is never rewritten.
Straight into Obsidian
Auto-appended to your vaultNotes land in Obsidian with tags intact, in the note you set as the destination (your daily note or a custom note). Searchable and linkable from day one.
You speak. This appears.
From voice to a structured Obsidian note — without touching the keyboard.
Grab milk and eggs on the way home, oh and detergent
--- title: Milk, eggs & detergent run tags: [groceries, errands] type: todo --- Grab milk and eggs on the way home, oh and detergent
* Illustration. Titles, tags, and types are generated on your device based on each note's content.
Nothing new to learn
Turn on AI Auto-Tagging once in Settings, and the AI works quietly behind the send button.
Open
Launches in 0.4 seconds (warm launch, iPhone 16e). With auto-start on (iOS 26+), voice input can start the moment it opens.
Speak & send
Talk, then one tap. Your memo lands in your inbox — and in Obsidian.
Organized, automatically
Title, tags, and type are added by AI without slowing the send. If AI is unavailable, a lightweight formatter takes over seamlessly.
AI tagging happens on your iPhone. Period.
All AI tagging runs inside your iPhone.
Your memos are never sent to an external server for it.
📱 On-device AI
Tagging and title generation run on Apple's on-device AI (Apple Foundation Models). No network calls are made for this processing.
🔁 Every iPhone covered
On-device AI runs on Apple Intelligence-capable iPhones (iOS 26+). On other devices, an on-device lightweight formatter produces the same structure automatically.
🔐 Same privacy-first design
Your on-device Outbox and send history are encrypted with AES-GCM-256, and memo bodies are not persistently stored on our servers. Email delivery is not end-to-end encrypted. See our privacy policy and privacy architecture.

Frequently asked questions
When does AI auto-tagging launch?
It's live now, shipped as a free app update. Update to the latest version on the App Store (or download the app free), set up Obsidian integration, and turn on AI Auto-Tagging in Settings (it is off by default).
Which iPhones are supported?
On-device AI tagging (Apple Foundation Models) runs on Apple Intelligence-capable iPhones on iOS 26 or later. On other devices, a lightweight on-device formatter (rules + natural language processing) automatically produces the same structure — title, tags, and type — so the feature works on any supported device (iOS 16+).
Are my notes sent to an external server?
Not for tagging or title generation. On supported devices Apple Foundation Models generates the title, tags and type, and on other devices a lightweight on-device process does; either way it happens on your iPhone. When you send a memo to your own inbox, the text is delivered through the Relay API and Resend, and email delivery is not end-to-end encrypted. See the privacy policy for details.
How are tags generated?
The AI reads your memo and adds 1–3 noun tags describing the content, a title of up to 20 characters, and a type such as todo, idea, or log. Your original text is never rewritten. With Obsidian integration on, the note is appended to your vault with the tags intact.
Is it useful without Obsidian?
For now it works only with Obsidian integration set up (Settings shows “Set up Obsidian to unlock”). Without Obsidian, the email subject stays the first line of the memo.
What if the AI produces a bad tag?
Every AI result is validated on-device; if it doesn't meet the constraints, the app automatically falls back to the lightweight formatter. In both cases your original memo text is preserved unchanged.
How much does it cost?
The app starts free — the Free plan includes 3 sends per day, with no time limit. Premium with unlimited sends is $2.99/mo or $29.99/yr. See the FAQ for details.
