SpiikWhy Spiik comes out ahead
Room for the whole conversation
Letterly is built around voice notes, and each note can run up to 90 minutes. Spiik Pro transcribes up to 2.5 hours per recording in the cloud. On a Mac with Apple silicon, local transcription has no length limit at all. A long meeting, lecture or interview fits in one recording.
Half the yearly price
Letterly's App Store listing shows $99.99 for 12 months of Pro, or $19.99 a month. Spiik Pro is $49.99 a year or $9.99 a month, with no monthly minute cap.
More than a rewrite
Spiik can paraphrase a recording or change its tone, but it goes further. You can ask the recording questions, or turn it into structured notes, a quiz, flashcards or a mind map. Then export it as text, PDF, SRT or VTT.
Bring in any audio, video or link
Both apps transcribe files you recorded elsewhere. Spiik also takes video from Photos, a YouTube link, a PDF, or a share straight from Voice Memos and WhatsApp.
When Letterly could make sense
Letterly can make sense if you mostly dictate short thoughts and want them rewritten as emails or posts, if you want to dictate into other apps with its keyboard, or if you need Android, Windows or the web. It also connects to Zapier and webhooks.
