ShortFast at a glance
ShortFast is an AI video automation platform for short-form video. It writes the script and hook, generates a faceless video in one of 27 visual styles (licensed documentary stock footage, AI video, or AI images drawn in a fixed art style such as stick figures, cartoon explainer, comic book, anime, whiteboard, 3D animation, claymation, classical painting or Greek statues), 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.
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.
Everything in the product is also available programmatically through a REST API, webhooks, and an MCP server for Claude, Cursor and other AI agents. ShortFast is built and operated by SachaSoft LLC.

ShortFast is an AI engine for short-form video. Generate faceless videos from real stock footage (or AI b-roll), or UGC-style videos with realistic AI actors, scenes and voices, complete with viral script, voiceover and captions, then auto-publish to YouTube Shorts, TikTok & Reels on a daily schedule, completely on autopilot.
Fully AI-generated visuals (like Sora or Runway) often look fake, get flagged by platforms, and fail monetization review. ShortFast builds on real stock footage from premium libraries that passes checks and looks like content from a real creator. AI b-roll is available too, when a clip calls for it.
Yes. Because the core footage is real, licensed stock (not AI-generated slop), your videos meet YouTube and TikTok quality standards. Many users have monetized channels built entirely with ShortFast.
Yes. Many creators earn $2,000-$10,000+ per month from YouTube AdSense and the TikTok Creator Fund with faceless content. The key is consistent daily posting in the right niche, which is exactly what ShortFast automates.
Top performers include finance & investing (high CPM), AI & tech news, motivation, scary stories, interesting facts, history, celebrity news, and health. ShortFast can generate content for any niche you choose.
Yes. Connect your YouTube, TikTok, or Instagram accounts and ShortFast publishes on your schedule, daily or multiple times per day, across multiple profiles, completely on autopilot.
With daily posting, most users hit YouTube's 1,000 subscribers + 10M Shorts views requirement in 2-4 months. TikTok Creator Fund eligibility (10,000 followers) usually comes faster. Posting consistently every day is what accelerates it.
No. ShortFast handles everything, researching trends, writing scripts, generating voiceovers, finding footage, adding captions, and editing. Just pick your niche and it creates ready-to-publish videos.
As many as your plan allows, and it's built for high volume. Most successful faceless channels post 1-3 times daily, and ShortFast can generate and publish all of them automatically.
Most faceless generators build each scene from AI-generated images. ShortFast builds on licensed stock footage matched to every line, with AI b-roll only where no clip fits, and can also produce UGC-style videos with AI actors. It posts to TikTok, Instagram Reels and YouTube Shorts across multiple accounts, and exposes the whole pipeline through a REST API and an MCP server. Plans start at $19 a month with a $1 3-day trial. The compare section covers each tool honestly, including where the other tool is the better pick.
Yes. Alongside faceless content, ShortFast can generate UGC-style videos with realistic AI actors for product demos and ads, but faceless automation is what most creators use to build and monetize channels.
