Concat
Concat is a free, open-source video editor meant as a CapCut replacement that runs entirely on your own machine. It covers auto-captions, text-to-speech voices, background removal, keyframes, titles, effects, filters and transitions with multi-track editing up to 4K, with no watermark, account or subscription. It runs on Windows, macOS, Linux, Android and iOS, and it can be scripted through a documented JSON-RPC and gRPC API, so scripts and AI agents can drive edits.
Added
OpenChatCut
A local-first AI video editor with a multi-track timeline that you drive by chatting with an agent; the AGPL edition is free, and a Pro desktop app adds transcription-based editing.
Added
BaoCut
An AI video agent for macOS and Windows that transcribes, subtitles, translates, dubs, cuts and animates your footage from plain instructions, with every result landing in an editable timeline instead of a one-shot export.
Added
iArt
iArt is an AI motion graphics agent that turns a text prompt, or uploaded images, PDFs, slide decks, audio or a web link, into animated scenes. It writes real animation code scene by scene (layout, typography, timing, transitions), so text stays exactly spelled and you can refine the result by chatting ("make the title two seconds shorter"). It handles explainers, logo animations, kinetic typography, animated charts, lower thirds and audio-synced captions, adds AI voiceover or a cloned voice, and exports MP4 (1080p on Pro, 4K on Ultra) or transparent WebM overlays.
