FUTO Swipe – A new swipe typing model
Points and comments are a snapshot, not live.
FUTO Swipe is an open, on-device swipe typing system challenging big-tech keyboards.
FUTO Swipe is a family of open models and algorithms for swipe typing, trained on over 1 million English QWERTY swipes collected voluntarily. It uses three model types: a lightweight universal encoder (635k params), a context language model (1.5M params), and a layout-specific decoder (304k params). Combined with a C++ beam search library, it achieves a top-4 fail rate of ~4% on the test set (under 1% ignoring out-of-vocabulary words). The system runs fully offline and is available in FUTO Keyboard for Android. Models are released under the FUTO Model License; the library is GPLv3.
What commenters are saying
Commenters are enthusiastic about the open model and its performance, with several saying it matches or beats Gboard and SwiftKey for swipe accuracy and responsiveness. However, significant frustration centers on the licensing: the keyboard app uses a non-free FUTO license, and commenters debate whether that license unfairly restricts removal of payment-related functionality and prevents inclusion in FOSS-only distributions. Some note the keyboard works well for English but lacks support for other languages like Korean, and the lack of iOS support is a dealbreaker for some. Several users praise the integrated offline voice input and text-editing shortcuts.
