Audionotes vs Letterly

Audionotes turns voice, audio, video, and text into structured notes using AI. Users can record or upload audio and video, add text or images, or submit a YouTube link. Transcription supports 99+ languages and speaker recognition; the service also creates summaries and custom outputs, supports chat with notes, and offers more than 100 output prompts. Integrations include Notion, Zapier, webhooks, and a WhatsApp bot, though Notion sync, Zapier triggers, and webhooks are Pro features. Webhooks can send note data to a custom endpoint; a public REST API is listed on the roadmap. The company says notes are encrypted in transit and at rest and are not used to train AI models. Its privacy policy names OpenAI, Google Gemini, Deepgram, and Assembly AI among providers that may process data for AI features. The free plan includes unlimited voice notes limited to one minute each, plus unlimited text notes, transcripts, and summaries. Pro costs $29.99 a month and allows recordings up to six hours. Recording uses the device microphone and does not capture audio from other sources such as speakers.

Letterly turns speech into text for messages, emails, notes, meeting summaries, journal entries, social posts, and other writing. Users can dictate inside apps such as Gmail, Slack, and Notion, or upload audio and video for transcription. Recordings can run up to 90 minutes, and speech is automatically detected across more than 90 languages, including when languages change mid-sentence. Users can select ready-made rewrite styles or create their own. Letterly can record offline, and Zapier and webhooks can send notes to other apps. Its MCP connects notes with Claude, ChatGPT, Cursor, Perplexity, Gemini CLI, Codex, VS Code, Windsurf, and Claude Code. Letterly says user words are not used to train AI; its DPA specifies encryption in transit and at rest, access controls, and regular security testing. Users can delete recordings and transcriptions through the app. It is available on Android, iOS, macOS, web, and Windows. In-app PRO prices include $19.99 a month, $89.99 a year, and $249.99, paid once.
