## Letterly

Letterly is built for people who would rather talk than type. You open the app and record, or speak directly into Gmail, Slack or Notion through the system dictation layer, and Letterly returns polished text matched to the format you need — a message, an email, a note, a journal entry or a social post. Rewrites are handled by AI: pick a ready-made style such as a formal email or a concise meeting recap, or describe your own format and reuse it later.

Longer recordings get more structure. Letterly handles talks up to about 90 minutes and can split a meeting or lecture transcript by speaker, then produce a summary alongside the full text. Recordings and rewrites are unlimited on the platform, audio and video files can be uploaded for transcription from any device, and notes can be searched by keyword or organized with tags. Offline recording means ideas captured without a connection still arrive in your library.

Letterly is available as a native app for iOS, Android, macOS and Windows plus a web client, with sync across devices. It connects outward too: translations into 90+ languages, text replacements for frequently used phrases, custom vocabularies, Zapier and webhook integrations, Apple Watch recording, and an MCP server that lets assistants like Claude or ChatGPT read and manage your notes. The company states that user content is not used to train AI models.

**Pricing & Plans:** Letterly is free to start with a freemium model. The free tier covers everyday dictation, while paid plans unlock higher usage limits and advanced features; pricing is shown in-app and on the website.

- **Dictate into any app:** Speak inside Gmail, Slack, Notion or any other text field and have clean text appear where you were typing, instead of switching apps.
- **AI rewrites and styles:** Convert raw speech into notes, emails, posts or meeting summaries using ready-made styles or your own saved formats.
- **Meeting and lecture transcripts:** Record up to around 90 minutes, get a transcript split by speaker, and generate a summary alongside the full text.
- **90+ languages with auto-detect:** Language detection happens automatically as you speak, and you can switch mid-sentence without changing settings.
- **Cross-device sync and integrations:** Native apps for iOS, Android, macOS and Windows plus web, with offline recording, translation, Zapier and webhooks, and an MCP connection for AI assistants.

**Strengths:** Works as both a dedicated app and a dictation layer inside tools you already use; Handles long recordings and separates speakers, which basic dictation tools often cannot; 90+ languages with automatic detection and mid-sentence switching; Available on iOS, Android, macOS, Windows and web with sync, plus offline recording

**Limitations:** Voice-first workflow is less convenient in shared or noisy environments; Free tier has usage limits, so heavy dictation requires a paid plan; Accuracy still depends on microphone quality and background noise

## Superhuman

Superhuman began as a famously fast email client and has expanded into a broader AI productivity suite. Today it spans Superhuman Go, an assistant that lives inside the apps and tabs you already use with inline suggestions and context-aware chat; Superhuman Mail, its email app with auto drafts, split inbox, auto labels, and auto archive; and Superhuman Docs, a collaborative workspace for documents, tables, data, and workflows.

A large part of the platform is built around agents. You can describe a task in chat or use a visual builder to create an agent, then share it with teammates or publish it to a company directory. Pre-built agents cover common knowledge-work jobs such as preparing for meetings by pulling relevant emails, notes, and docs, turning meeting notes into recaps for each owner, checking claims against company data, and humanising AI-generated text. Superhuman also sits inside the wider Superhuman Platform alongside Grammarly and GPTZero.

Superhuman is a paid product aimed at individuals, teams, and enterprises. The suite integrates with Gmail, Google Calendar, and many workplace tools, and the enterprise tier adds administration and security controls. For exact plan tiers, seat pricing, and included features, check the official pricing page, since packaging has changed significantly as the product has grown beyond email.
