Developer opts for on-device AI in writing assistant for privacy and offline use

The creator of the DraftKey writing assistant chose to run its AI model locally on users' computers rather than via a cloud service. This approach ensures user text remains private, works without an internet connection, and avoids per-use API fees. The trade-off is that the app requires a significant 1.1 GB model download, at least 8 GB of RAM, and a Mac with Apple Silicon chips. While the local model is less powerful than large cloud alternatives, it suffices for tasks like short rewrites and autocomplete. The developer notes that user privacy has emerged as the most appreciated feature of this design.
