OpenWhispr vs Transcript.so

OpenWhispr is an open-source voice-to-text assistant for dictation, transcription, and notes. Dictation works in apps that accept text, including ChatGPT, Claude, Cursor, Google Docs, Gmail, Slack, and Teams. It supports more than 100 languages with automatic language detection. For meetings, it can capture computer audio without joining a call as a bot, then create structured notes with decisions and action items. The note taker works with Zoom, Google Meet, Microsoft Teams, Slack, Discord, Webex, and other apps that play computer audio, without plugins or integrations. Audio can be processed on the device with local speech models or through OpenWhispr Cloud, which says it discards audio without retaining it. The company says user content is not used to train AI models. Free includes 2,000 transcription words per week and five meeting-recording hours per month. Pro costs $6.67/user/mo (annual). OpenWhispr runs on iOS, Linux, macOS, and Windows.

Transcript.so converts uploaded audio and video into searchable text. It detects languages automatically, labels speakers, lets users click a sentence to replay that moment, and exports transcripts as TXT, DOCX, PDF, CSV, SRT, or VTT. The service supports more than 90 languages and accepts formats including MP3, WAV, M4A, AAC, FLAC, OGG, OPUS, WMA, AIFF, MP4, MOV, WEBM, MKV, MPEG, and AVI. Users can search saved transcripts for topics. The maker says Whisper handles most files and another diarization engine is selected for multi-speaker or long recordings. The free plan allows three transcriptions daily, with files up to 30 minutes or 50MB. Unlimited costs $10.00 per month billed yearly ($120). Accuracy may drop with names, jargon, crosstalk, strong accents, or noise. Files remain until deleted and are encrypted, private, and not used to train models.
