CutFast is an AI-native video editing tool that runs in the browser, and its core idea is "editing video like using a highlighter." It is aimed at users who need to quickly extract highlight clips from long videos and remove redundant content, replacing traditional timeline dragging with selecting subtitle text.
In terms of use, CutFast is mainly used to quickly produce highlight clips and condensed videos. According to the official description: the AI discards filler words, repeated content, and silent parts, then exports highlight clips, with the entire process completed in the browser without uploading.
Its main capabilities include: automatically removing filler words, repeated content, and silence; selecting the scenes to keep by highlighting subtitles, which is what the official description calls "click a line to keep it, you are selecting text, not dragging a timeline"; editing and exporting highlight clips in the browser; supporting pasting video links or opening local files, and local files are not uploaded and remain on the device.
In terms of usage, users can paste a video link or open an existing file on their device. After opening, the video subtitles are presented as lines of text; users click a line to keep it, and unselected lines are removed from the edit. The interface prompts "there are no kept lines in the edit yet" and prompts users to click a line to keep it. The tool also provides browser compatibility detection, checking whether the current browser can edit here.
In terms of applicable scenarios and supported platforms, the official list includes YouTube, Bilibili, TikTok, Xiaohongshu, Xiaoyuzhou Podcast, and local videos. It is suitable for creators who need to quickly extract key quotes or highlight clips from long content such as podcasts, interviews, and talking-head videos.
In terms of pricing, the official offering includes a free trial ($0, 3 free edits per day), pay-per-use Fafa ($30), and a lifetime membership ($399).
In terms of limitations, the materials mention that local files are not uploaded, but do not specify the supported video formats, export formats, resolution limits, maximum processing duration, or other system requirements beyond the browser environment. This information is not currently provided.
