Both write, voice, caption and auto-post faceless videos from a topic on a schedule, and both can draw every scene in an art style. AutoShorts is built around one series per channel and adds 30 languages and voice cloning; ShortFast adds licensed stock footage, AI actors and several accounts on one plan.
These two are closer substitutes than most pairs on this site. Both take a topic, write a script, add a voiceover and captions, and post the finished video to TikTok, YouTube and Instagram on a schedule you set once. Both can draw every scene in a fixed art style and animate the stills for an extra cost. The differences are what else each can build a video from, how many channels one plan covers, and language support.
AutoShorts is the better pick if you need one of its 30 listed languages, if you want to clone your own voice, or if you want one of its pop-culture looks such as Lego, Minecraft or GTA V. ShortFast is the better pick if you want the option of real licensed stock footage or AI actors next to the art styles, if you run more than one account, if you need videos longer than 90 seconds, or if you need an API.
On price the entry point is the same, $19 a month, and AutoShorts now lists its Daily ($39) and Hardcore ($69) tiers on its own homepage. The models still diverge after that. Each AutoShorts series links one channel per platform, so a second channel means a second series. ShortFast's Pro and Advanced plans include several automations and social accounts. Work out how many channels you want to run before you compare the numbers.

AutoShorts prices by cadence and by series. Its homepage lists Starter at $19 a month for three posts a week, Daily at $39 for one post a day and Hardcore at $69 for two, each with one series and a monthly allowance of motion credits (27, 62 and 124). Yearly billing is labelled "2 months free", but the yearly prices are not shown on the public page. There are no refunds, though you can cancel at any time.
The part that matters is the series. A series links one channel per platform, so a second niche, or a second TikTok account, needs another series. Its FAQ also says an account can only be on one plan type at a time, so mixing a Daily series with a Hardcore series means opening a second account.
ShortFast prices by plan and credits instead. Starter is $19 a month for 1,000 credits, one automation and one social account. Pro is $39 for 5,000 credits, three automations, up to three posts a day per automation and three accounts. Advanced is $99 for 10,000 credits, six automations, six accounts and videos up to 15 minutes. A typical AI art-style video uses about 25 credits and a stock-footage one about 12, so Starter covers about 40 illustrated or 80 stock-footage videos a month; fully animated videos use about 464. Yearly billing takes 20% off. For one channel the two are close; the gap opens the moment you want a second or third account.
Both tools now draw videos in fixed art styles. AutoShorts generates a still image for each scene and animates it if you spend motion credits; its showcase includes Lego, Disney Toon, Minecraft, GTA V, Expressionism, Comic Book and Children's Book looks. ShortFast has 27 styles, among them stick figures, cartoon explainer, whiteboard, anime, comic book, 3D animation, claymation, pixel art, classical painting and Greek statues, and its Animate images option turns each scene into a short clip on videos up to two minutes.
Where they differ is what else a video can be made of. ShortFast can build it from licensed stock footage, from footage mixed with AI images, or from continuous AI video, and it makes UGC-style videos with AI actors. AutoShorts has no stock footage option. Real footage reads as filmed, which matters in niches like finance, health, travel or product reviews where viewers expect to see the real thing.
The monetization question is subtler than either side likes to admit. AI-image channels can be and are monetized. What platforms act on is repetitive, mass-produced output, which YouTube has called inauthentic content since July 2025, and both tools can produce that if you leave the defaults alone. Write original scripts, vary the topic and structure, and review the first videos of any series before you let it run.
The overlap is large. Both write the script, generate a voiceover, burn in captions, and post to TikTok, YouTube and Instagram on a schedule without you touching each video. Both let you set up an automation once and let it run. AutoShorts caps videos at 90 seconds, while ShortFast's Advanced plan extends to 15 minutes. AutoShorts' FAQ also advises new accounts not to post more than once a day, which is sensible advice with either tool.
AutoShorts has several things ShortFast does not. It lists 30 languages, including Arabic, Hindi, Indonesian and Turkish. It offers voice cloning. Its preview step lets you edit the script, title, images and background music of each video before it posts. And its UGC Hook format puts a lip-synced AI creator at the start of a marketing video.
ShortFast has its own list. Licensed stock footage and continuous AI video sit next to the art styles. Its API and MCP server can also turn any faceless video into the next episode on the same theme, and A/B hook variations of a single video are coming soon. It runs several accounts from one plan with its own schedule and timezone for each automation. And everything is exposed through a REST API, webhooks and an MCP server, so an agency or a developer can drive it from their own systems. AutoShorts publishes no API.
