Shortlist Whisperstream when dictating emails, messages, and documents faster than typing matters most, and iMemo when transcribing lectures and interviews for later review matters most. Trial each on a few real meetings before you commit — the better fit usually shows fast.

Cross-platform AI recorder that turns meetings, lectures, and imported files into searchable transcripts and summaries.
Whisperstream is a downloadable Windows desktop application from Lanreal Technologies Inc. that converts speech to text using push-to-talk dictation. Transcription runs entirely locally on the user's PC via the NVIDIA Parakeet model, so audio is never uploaded to the cloud and no account is tied to the user's voice. It works across any application without add-ins or setup, inserting dictated text directly into tools such as Outlook, Gmail, Slack, VS Code, browsers, and Claude Code. Beyond live dictation, it can import and transcribe existing audio recordings, and it keeps a searchable transcript history with audio replay, encrypted on the device. Additional features include AI cleanup that tidies spoken input, a custom vocabulary for names, jargon, and acronyms, per-app custom AI prompts, support for 25 languages, global keyboard shortcuts, and full offline operation. It requires Windows 10 or 11 (64-bit) with at least 8GB RAM. It targets professionals and privacy-conscious knowledge workers who want fast, local voice input rather than typing.

iMemo is an AI-powered audio note-taking app available on both iOS and Android that records, transcribes, and summarizes meetings, lectures, interviews, and personal notes. Users can capture high-quality audio directly in the app or import existing audio and video files in formats such as MP3, WAV, FLAC, and MP4, then have the content transcribed into searchable text across many languages. iMemo generates AI summaries from lengthy recordings, offers dual-language viewing for translation, and can identify issues and attributions within a conversation to help surface action items. Recordings and notes are organized into projects and folders with advanced search, and content can be exported in multiple formats including TXT, PDF, and several audio formats. iMemo records without joining calls as a bot participant, capturing audio on the device instead, and it emphasizes a privacy-focused approach where data stays on the device. The app is positioned for people who want to focus on a meeting or lecture without manually taking notes and review organized, searchable summaries afterward. Pricing varies by plan. Check the official website for current pricing.
