InkFrame

InkFrame is an offline-first creative tool that combines a handwriting canvas, video editor, and AI-powered notes into one seamless experience.

Handwriting Canvas — Infinite pages with pencil-texture shaders for natural strokes. Optimized for Onyx Boox and other E Ink devices.
Video Editor — FFmpeg-powered engine with trim, speed control, and transitions. All processing is local — no cloud uploads required.
AI Notes — Rich text and Markdown editor with timeline, calendar, and map views. Built-in AI writing assistant.
Smart Cutout — MLKit portrait segmentation for one-tap background removal. Runs offline for instant results.
Security & Sync — App lock with biometrics and PIN, plus Nextcloud encrypted sync. Your data, your control.

InkFrame — create freely, starting with every stroke.
