I build one of the products in this comparison. That is the conflict, stated in the first line. I will not call ShortsFast the best for every creator. It is built for recurring faceless series. A creator with a podcast backlog, a finished script, or a need for frame-level editing should often choose something else.
This guide uses public product pages, help docs, and pricing pages checked on 2 August 2026. I did not run a fake seven-tool benchmark or score output quality with invented numbers. The useful facts here are simpler: what input each tool accepts, what work remains manual, where it publishes, and what its public plan actually measures.
Start with the input, not the vendor
The phrase AI Shorts generator hides three different jobs. One tool starts from an idea and builds a full video. Another starts from your script and gives you an editor. A third starts from an existing long video and finds clips. Those tools can all produce a vertical MP4, but they do not replace the same work.
- Blank idea: choose an end-to-end generator with scripting, visuals, voice, captions, and publishing.
- Finished script: choose for scene control, media replacement, voice choice, caption styling, and export speed.
- Long recording: choose a repurposing tool that finds moments, reframes speakers, and creates several clips.
- Recurring faceless series: check scheduling, destination accounts, monthly output, and review controls.
Define the bottleneck before opening a pricing page. If writing takes two hours and editing takes ten minutes, buying a clipper misses the problem. If you already record a weekly interview, paying a generator to invent unrelated scenes wastes the asset you own.
Seven tools in one constraints-first table
The table is not a quality ranking. It is a routing table. Direct publishing matters when the goal is a recurring schedule. Deep editing matters when every scene must match a client brief. Repurposing matters when the expensive work, recording, already happened.
ShortsFast for recurring faceless series
ShortsFast starts from a niche and recurring series. It handles script, vertical video, schedule, and direct publishing to YouTube Shorts and TikTok. The public Starter plan is $29 per month for 10 videos, one series, and three publishing days per week. Pro is $49 per month for 30 videos, three series, and daily publishing. Both list six voices, no watermark, and a seven-day money-back period.
Choose it when the job is maintaining one or several faceless series, not making one polished ad. The useful unit is finished scheduled videos. That makes monthly capacity easy to read. Start with the dedicated AI YouTube Shorts generator, faceless video generator, or faceless reels generator page for workflow-specific details.
Do not choose it when you need a detailed timeline, uploaded interview footage turned into highlights, or frame-by-frame client revisions. The product deliberately trades deep manual editing for a shorter path from topic to published series. See the broader faceless video alternatives before deciding.
AutoShorts.ai for one automated series
AutoShorts.ai writes, generates, and posts recurring videos to TikTok, YouTube, and Instagram. Its public plan data checked on 2 August listed Starter at $19 per month for three videos per week, Daily at $39 for seven per week, and Hardcore at $69 for fourteen per week. The listed plans each allow one series.
That structure fits a creator who wants to push one concept at a steady cadence. It is less convenient for testing three unrelated niches under one subscription because series count, not just weekly frequency, becomes the limit.
Compare the expected monthly output, destination support, and approval step. Fourteen posts per week sounds large, but volume is useful only when the format can stay specific enough to avoid becoming repetitive.
ShortsNinja for credit-based series and editing
ShortsNinja combines generation with a scene editor. Its official help page documents controls for voice, visual assets, music, captions, metadata, aspect ratio, export, and direct publishing when an account is linked. That makes it a better fit when you want an automated series but still expect to replace scenes or adjust presentation.
Public plan information checked in August listed Starter at $19 for 125 credits, Pro at $39 for 315, Creator at $69 for 630, and Influencer at $129 for 1,260. ShortsNinja says a one-minute video uses roughly ten credits, so the entry plan is roughly twelve one-minute videos. Actual use depends on the chosen workflow.
Credits add flexibility but make budgeting less direct than a fixed finished-video allowance. Run one representative video before multiplying the plan price by a guessed monthly volume.
Faceless.video for three-platform automation
Faceless.video presents a text-to-video workflow that posts to TikTok, Instagram Reels, and YouTube Shorts. It fits creators whose main requirement is the same recurring vertical format across three destinations.
Its public landing page did not expose a clear current price during this review. That is not a reason to guess from an old comparison post. Open the checkout, confirm price, renewal period, video allowance, and cancellation terms before entering payment details.
The selection question is coverage versus control. Three-platform posting removes handoffs. It does not remove the need to inspect facts, pronunciation, visual relevance, title, and disclosure before a video reaches an audience.
Crayo for hands-on short assembly
Crayo is closer to an assisted short-video workspace. It offers script, voice, background, captions, effects, music, and generated images. The public pricing page listed Essential at $19 per month with 40 export minutes, 30 voiceover minutes, 10 avatar minutes, and 100 generated images. Clipper was $39 and Pro was $79 when checked.
Choose Crayo when you want to assemble and revise individual shorts. Its minute and asset limits reward creators who understand their normal video length. A channel making 25-second clips consumes the allowance differently from one making two-minute Shorts.
Export-based production also leaves scheduling as a separate job. That is fine when a human already reviews every upload. It is a poor fit if the only goal is an unattended recurring series.
Invideo AI for prompt-led production
Invideo AI starts from a prompt or script and builds a video that can be revised through prompt-led instructions. Its current pricing uses credits. The official page variant checked for this guide showed Plus at $17 per month billed yearly with 75 credits, Max at $85 with 390, and Generative at $170 with 800. A free plan was available.
The critical detail is credit consumption. Invideo documents that different generation modes use credits at different rates and that unused plan credits do not roll over. A headline monthly price cannot tell you the cost of your format.
Choose it for prompt-led production and broad video work. Test one representative Short, record the credits used, and only then estimate monthly capacity. Do not treat the advertised credit number as a video count.
OpusClip for long-form repurposing
OpusClip solves a different job. It takes an existing long recording, identifies clip candidates, reframes them, and prepares short-form output. If you publish interviews, webinars, lessons, or podcasts, this can remove more work than a blank-page generator.
The official pricing page listed Free at $0, Starter at $15 per month, Pro at $29, and Business with custom pricing. Social scheduling is listed on Pro and Business, with support for YouTube Shorts, TikTok, Instagram, LinkedIn, Facebook, and X.
Do not buy it to create a faceless story from nothing. The source recording is the asset. Also review every suggested cut. A moment can look strong in isolation while removing the qualification that made the speaker accurate.
Compare price units before monthly prices
Normalize each offer into the cost of your actual workflow. Write down expected videos per month, average duration, number of series, number of destination accounts, and whether publishing is included. Add human review time. A $19 editor plus a separate scheduler can cost more in attention than a $29 finished-video plan.
Run one representative video before upgrading
A useful trial uses the format you plan to publish, not the easiest demo prompt. Give every candidate the same topic, target duration, factual source, pronunciation challenge, and visual constraint. Record the time needed to correct the script, replace irrelevant scenes, fix captions, confirm music rights, export, and schedule. Keep the output private until those checks are complete.
Then repeat once with a different topic. The second run reveals whether the first result depended on a lucky prompt or a familiar subject. For credit plans, record the exact balance before and after both tests. For finished-video plans, confirm whether a failed render or revision uses an allowance. For auto-publishing plans, connect a test destination first and verify title, description, visibility, schedule, and account. Those small checks expose the real monthly capacity better than a long feature list.
Annual billing deserves its own line. A lower displayed monthly number may require a full-year payment. Prices also change. Treat every number above as a dated snapshot and verify it on the linked official page.
YouTube policy checks before publishing
Check duration and music claims
YouTube says square or vertical videos up to three minutes can qualify as Shorts. Since 24 September 2026, new Shorts longer than one minute with an active Content ID claim are no longer automatically blocked and may remain playable. A generator exporting a two-minute video does not guarantee that every included track is licensed for that use; check the actual Studio restriction and current YouTube guidance.
Disclose realistic altered content when required
YouTube requires disclosure when content is meaningfully altered or generated and appears realistic. It does not say every use of AI for a script, captions, minor edits, or clearly unrealistic scenes requires the label. YouTube also says disclosure itself does not reduce monetization eligibility. Read the full AI disclosure guide before publishing realistic synthetic people, places, or events.
Automation does not make repetitive content eligible
YouTube monetization policy focuses on original, authentic value and can reject mass-produced or repetitive templated content. Changing a background while reusing the same thin script structure is not a durable channel strategy. Use the channel pre-flight checklist to review sourcing, variation, rights, and viewer value.
