It runs on your phone. Speech and cleanup AI are on-device after a one-time download, so it works in airplane mode and your voice isn't uploaded. It's not a keyboard. Keep Gboard, Samsung or whatever you use. Blot sits beside it in any app. Free, no account. No ads, no tracking, nothing to buy. You earn skins for Blot just by using it. Small phones too. Android 7 and up, and it picks models that fit your phone.
