ShortFast is an AI video automation platform for short-form video. It writes the script and hook, generates a faceless video from licensed stock footage or AI b-roll, or a UGC-style video with AI actors, adds a voiceover and burned-in captions, then publishes the finished video to TikTok, Instagram Reels, YouTube Shorts on a daily schedule.
It is built for people who need a video a day and do not have long-form footage to cut from: faceless channel operators, agencies running many client accounts, and businesses using short video for leads. Clipping tools such as OpusClip start from a recording you already have; ShortFast starts from a topic.
A typical run starts from a niche or a topic. ShortFast researches an angle, writes the hook and script, matches every line to licensed stock footage or generates AI b-roll where no clip fits, records the voiceover, burns in captions, and renders a 9:16 video. If you connect accounts, it publishes on the schedule you set, to TikTok, Instagram Reels, YouTube Shorts, across as many accounts as your plan allows.
The same pipeline can produce UGC-style videos with AI actors for product demos and ads, and the variations feature renders several openings of the same video so you can test hooks.
Plans start at $19 per month (Starter $19 · Pro $39 · Advanced $99), with a 20% discount billed yearly. Every monthly plan starts with a 3-day trial for $1, with full access and no long-term commitment.
The trial is $1 for 3 days on any monthly plan, with full access. Cancel before it ends and you are not charged again. Yearly plans are billed once, up front, at 20% off the monthly rate.
ShortFast is built and operated by SachaSoft LLC. Chafik Gharbi is the founder of SachaSoft LLC and builds ShortFast, the AI pipeline that writes, renders and publishes short-form video for creators, agencies and businesses.
