Predis.ai is an AI ad and social content platform: ads, posts, carousels and reels made in your brand kit, then approved, scheduled and, from its Rise plan, auto-posted. ShortFast is a faceless video series engine that writes each short from a topic, renders it in one of 27 styles and posts it to TikTok, Instagram Reels and YouTube Shorts on your schedule.
Predis.ai is an AI ad and social content platform that makes ads, posts, carousels and reels in your brand kit and publishes them across your channels; ShortFast is a faceless video series engine that writes, renders and posts a new short to TikTok, Instagram Reels and YouTube Shorts for every slot in your schedule. Pick Predis.ai if one brand or several need ads, carousels and on-brand posts on many channels, with approvals and competitor research; pick ShortFast for a faceless channel or series that writes and posts itself.
Both can make a faceless video and post it on a schedule, but they automate different things. Predis.ai's auto posting, on Rise and up, plans a week of posts at a time from your business details, content sources and products, at 5, 10 or 14 posts a week. A ShortFast automation writes the next episode for each posting slot, with a new topic, script, title, description and footage in the same tone, format and length, then posts it or emails it to you.
Predis.ai Core is $32 a month for 1,300 credits, about 33 videos by its count, without auto posting, which starts on Rise at $79. ShortFast Starter is $29 for 2,000 credits, about 80 one-minute stock-footage or 50 AI art-style videos, with one automation that posts to one social account. Neither has a free plan: Predis.ai's 3-day trial is free but takes a card, and every ShortFast monthly plan starts with a 3-day trial for $1.
Side by side
| Dimension | ShortFast | Predis.ai |
|---|---|---|
| Made for | Faceless short-video channels and series, from a topic, a prompt or your own script; it writes the script and hook. | Businesses and agencies that need ads and social content, made in a brand kit from a product URL, a prompt, an image, a blog post or a reference ad. |
| Formats and visuals | Video only: faceless videos in 27 styles (licensed documentary stock footage, AI video, or AI images in a fixed art style) and UGC-style videos with AI actors. Your own clips can replace any scene. | Video, UGC and product ads, faceless videos, image ads, carousels, stories and memes. Scenes use stock clips, AI images or AI video from models such as Google Veo, Kling AI and Seedance. |
| Voices and captions | 40+ voices. Burned-in, word-by-word captions: 9 styles, 18 fonts, 60+ languages detected automatically; no translation. | 400+ AI voices across 19 languages and accents, voice cloning, and AI dubbing that translates the script, voiceover and subtitles. |
| Length and frame | Up to 3 minutes on every plan, or 8 to 15 minutes on Advanced. Vertical, or 16:9 on every plan. | Its faceless video FAQ says about a minute at most; its plan comparison lists a video maker of up to 5 minutes. 9:16, 1:1 or 16:9, in 1080p. |
| Platforms and accounts | TikTok, Instagram Reels and YouTube Shorts. One account per platform per profile: 1 social account on Starter, 3 on Pro, 6 on Advanced (2 profiles). The same video and caption go everywhere. | Instagram, Facebook, TikTok, YouTube Shorts, LinkedIn, Pinterest, Google Business and X, each sent its own format. Plans cover 10, 20 or 60 social accounts, and several pages on one platform each count as one. |
| Automation and approvals | Each automation writes the next episode for every posting slot (new topic, script, title, description and footage; same tone, format and length; recent titles checked), then posts it or emails it to you. No approval step, though the next two episodes wait in a queue where you can edit them, except their script. | Auto posting, on Rise and up, plans a week of posts at a time from your business details, content sources and products, at 5, 10 or 14 posts a week. Drafts can wait for approval: “nothing goes out until someone approves it”. |
| Editing | Write or paste the script first. Afterwards, edit captions, B-roll, music, title and post text and re-render; an edited script can't be re-voiced. | A browser editor: rewrite a line, swap visuals or the voiceover, trim and reorder scenes, add text, stickers or stock clips. |
| Pricing and trial | Credits: $29 (2,000), $39 (5,000) or $99 (15,000) a month; 20% to 48% off billed yearly; extra credits $10 per 1,000.

Its pricing page lists no free plan; each plan starts with 3 days free, card required. |
| Refunds | At ShortFast's discretion, per its terms; the $1 three-day trial lets you test first. | Non-refundable after the trial, per its pricing FAQ and terms. A September 2026 help article says a charge after a forgotten trial is typically refunded in full if paid features weren't used, and renewal refunds are handled case by case. |

Yearly figures are what Predis.ai's pricing page showed for annual billing on October 23, 2026, and every plan lists API access. Its image and video counts are its own estimates, and its API docs say remaining credits expire at the end of the billing cycle. Credits don't convert between the two, and ShortFast's video counts are estimates, not limits.

Predis.ai keeps a brand's content in one place. A brand kit holds the logo, colors, fonts, tone of voice and key messaging, and everything made under it, from video and UGC ads to image ads, carousels and reels, comes out in that look. Start from a product page, a prompt, a photo, a blog post or an ad you like, or build from a connected Shopify, WooCommerce or Wix store. Competitor analysis shows what rival Facebook and Instagram accounts post, and insights show which posts and ads did best.
Teams get unlimited members on every plan, a workspace per brand or client and approvals before anything goes out, while the scheduler formats the same video as a Reel, a Short and a TikTok. For ads and on-brand posts in many formats on many channels, Predis.ai is the better pick; ShortFast makes videos only and has no analytics yet (they're coming soon).
ShortFast fits a faceless channel or series that must keep publishing without anyone making each video. Set up an automation once, with a series brief of up to 500 characters, a style, a voice and a schedule. For each posting slot it writes the next episode, with a new topic, script, title, description and footage in the series' tone, format and length, after checking recent titles, then posts it or emails it to you. Nothing waits for approval, so watch the first episodes.
Its 27 styles run from licensed documentary stock footage and AI video to fixed art styles such as cartoon explainer, anime or classical painting, and your own clips can go into any scene. Put a call to action in the brief and the scripts end with it. Videos run up to 3 minutes on every plan, or 8 to 15 minutes on Advanced.
Automated series live under the platforms' rules. YouTube's monetization policies say channels where content “feels interchangeable from video to video” aren't allowed to monetize, and its spam policy covers “using automated tools or AI to churn out high volumes of similar content with minimal changes”. TikTok requires a label on realistic AI-generated content. With either tool, vary the topics and check the first videos of any automated series.
On October 23, 2026, Predis.ai's pricing page listed Core at $32 a month, Rise at $79 and Enterprise+ at $249, or $19, $40 and $212 a month billed yearly, for 1,300, 3,200 and 10,000 credits, which it puts at about 33, 80 and 250 videos. Core's plan card reads “No Auto Posting”; Rise and Enterprise+ include it.
ShortFast Starter is $29 a month, or $15 billed yearly, for 2,000 credits and one automation posting to one social account. A minute of stock-footage video uses about 24 credits, a minute in an AI art style 37 and a minute of AI video 440; extra credits cost $10 per 1,000. The credits don't convert, so price the posting plan you want on both: hands-off posting starts on Predis.ai's Rise ($79 a month, or $40 billed yearly) and on ShortFast's Starter ($29, or $15 billed yearly).
