Krita Foundation

Krita Foundation offers the Fast Sketch Cleanup Plugin, an experimental tool that uses a neural network to automatically convert a hand-drawn sketch into cleaned-up line art, helping artists with the inking step of their workflow. The plugin was developed in partnership with Intel and first released in December 2024.

The plugin takes a raster image of a hand-drawn sketch as input and produces a new layer containing cleaned-up, inked-style lines. It uses a convolutional neural network model trained by the Krita team exclusively on artwork donated by community members. The model runs entirely on the user's local machine — no internet connection, server, or account is required. As of February 2025, an updated version (1.1.0) was released with an improved interface, pre- and post-processing options, and support for custom models. The plugin is described as still experimental and available for Windows and Linux.

The Krita Foundation announced a policy change in October 2023, stating that the Krita-artists.org community forum would no longer allow posts that promote AI tools, citing support for artists and artists' copyright protection. This is an editorial and community governance decision rather than a product feature.

The policy was announced jointly by the Krita-artists.org forum admins, moderators, and the Krita team following internal discussion. The policy specifically covers posts that promote AI tools on the community forum; it does not describe any automated AI-based moderation system. The Krita team's 2024 development roadmap separately confirmed that internal discussions had concluded generative AI features would not be added to Krita, while assistive AI (such as sketch inking) remained under investigation.
