Worth knowing
Letterly
- Letterly's site has no pricing page; prices here come from its US App Store listing, which shows several price points for yearly and lifetime PRO.
- The support page limits the free version to 10 recordings of up to 3 minutes each.
- Vendor pages disagree on recording length: the support page says 15 minutes on Pro, the homepage and App Store listing say up to 90 minutes.
Whisper Memos
- iPhone and Apple Watch only: the App Store listing says it is designed for iPhone and not verified for macOS, and no Android or web app is offered.
- There is no free plan. The app is free to try, then needs a subscription at $9.99 a month or $69.99 a year.
- Transcription happens online: memos recorded offline are saved on the device and uploaded once a connection returns.
- Each recording is limited to 90 minutes, and imported audio must be an audio-only file; video files are rejected.
Key features
Letterly
- Dictation in any app
- Speak inside Gmail, Slack, Notion or any other text field on a computer, or use the Letterly keyboard on iPhone, and the text is inserted where you are typing.
- Voice notes with AI rewrites
- Record a thought in the app and get cleaned-up text. Choose from 25+ premade rewrite styles, such as an email, post or summary, or build your own.
- Meeting and lecture recaps
- Long recordings, up to 90 minutes per note, become a transcript split by speaker along with a summary.
- 90+ languages and translation
- The spoken language is detected automatically, including switches mid-sentence, and any note can be translated into 90+ languages.
- Audio upload and offline recording
- Transcribe audio and video recorded outside the app, and record without an internet connection when you are away from one.
- Zapier, webhooks and MCP
- Send notes to other apps through Zapier or webhooks, and connect Claude, ChatGPT or Cursor over MCP to search, manage or rewrite your notes.
Whisper Memos
- One-tap recording on iPhone and Watch
- Recording starts from a Lock Screen widget, an Apple Watch complication, the Action Button, Back Tap or Siri. The Watch app records on its own without the iPhone nearby.
- Transcripts delivered by email
- Each memo is transcribed, split into readable paragraphs and emailed with its summary by default, so it can be dealt with later from the inbox.
- Choice of transcription models
- An Automatic setting picks a model for each recording, or you can choose one yourself, such as OpenAI Whisper or ElevenLabs Scribe. More than 50 languages are supported.
- Summaries with custom prompts
- Every memo gets an AI summary, and extra summary tabs can be defined with your own prompts, for example one that pulls out action items.
- Meeting mode
- Turning on Meeting mode produces a transcript organized by speaker, with an optional hint that up to 2 to 6 people will talk. Each speaker can then be given a name and a color.
- Integrations and agents
- Built-in Notion and Reflect integrations, Mail Drop, Zapier and webhooks send memos elsewhere, and named agents route a memo when its name is spoken at the start.
