Pithflow vs Aiko
Aiko is a one-time-purchase Apple app that turns recordings and imported audio or video into text on your own device. Pithflow is live dictation: hold a key, speak, and polished text lands in whatever app you're typing in. Different jobs, and some people use both.
Short answer: Aiko if you need recordings and audio files turned into text privately on a Mac, iPhone or iPad. It runs on-device and costs $24 once. Pithflow if you want to write by voice in any app on Windows or a Mac, with AI cleanup. Pithflow does not transcribe uploaded files.
