Pricing checked July 2026 (tryvoiceink.com: $25 / $39 / $49 one-time licenses for 1, 2, or 3 Macs; source code on GitHub under GPL). Prices and product claims change, so verify current terms on VoiceInk's site before buying.
VoiceInk's trump card is that it's open source under GPL v3. You can read every line, audit the privacy claims yourself, and even compile it from source. Its Power Mode applies per-app settings automatically, and it has an active community shaping the roadmap on GitHub. If open source is a hard requirement for the software you trust with your voice, VoiceInk is the honest pick, and it's pay-once too.
oto transcribes audio and video files with a batch queue, translates speech to English (with Whisper), and records long-form meetings with your mic and the meeting audio captured separately. All of it is included at $8, a fraction of VoiceInk's $25-$49.
Whisper, Parakeet v3, and Apple's on-device speech on newer Macs. Pick the engine that fits each job instead of being limited to two.
Apple's review process, sandboxing, automatic updates, and easy refunds. No license keys, no manual update downloads, nothing to compile.
Scope and price. VoiceInk focuses on live dictation and trades on open source. oto covers dictation plus file transcription, translation to English, and meeting recording, for $8 instead of $25-$49.
VoiceInk is live-dictation only, per our last check; it doesn't import or batch-transcribe audio files. oto handles WAV, MP3, M4A, AIFF, AAC, FLAC, CAF, MP4, and MOV out of the box.
