Both write, voice and caption a faceless short from a niche and post it to TikTok, Instagram and YouTube on a schedule. EasyViral is built around animated AI scenes and starts at $9; ShortFast adds stock footage, 27 fixed styles, AI actors and an API.
EasyViral and ShortFast are direct substitutes. Both take a niche or a topic, write the script, generate the visuals, voice and captions, and publish the video to TikTok, Instagram or YouTube at the time you set. EasyViral focuses on animated AI scenes, which it describes as moving scenes rather than zoomed still images, across 38 ready-made niches. ShortFast offers 27 styles, from licensed documentary stock footage to fixed art styles such as stick figures, anime or claymation, plus UGC-style videos with AI actors.
EasyViral is the better pick if you want fully animated AI videos at the lowest price, if you want to clone your own voice (included on every plan), if you want 16:9 explainers up to 10 minutes in its Sketch Explainer format, or if you want a refund window: it refunds in full within 14 days if you haven't used any credits. ShortFast is the better pick if you want stock footage or illustrated styles, many videos a month for the same money, UGC-style videos, or an API and MCP server.
The pricing math depends on the video type. EasyViral charges 400 credits for a 60-second video, so its $9 Creator plan (1,750 credits) covers about 4 one-minute videos a month. ShortFast's $19 Starter (1,000 credits) covers about 80 stock-footage or 40 AI art-style videos at typical costs, but only about 2 fully animated ones. For animated AI video, EasyViral is far cheaper; for everything else, ShortFast goes much further.

EasyViral's pitch is motion: its site describes AI videos with moving scenes, not zoomed still images, in a set of art styles and 38 ready-made niches such as Dark Stories, Finance, Psychology, True Crime, Lego Stories and Brainrot. It also has a Sketch Explainer format in 16:9 that runs up to 10 minutes, which is unusual among faceless auto-posters.
ShortFast gives each channel a fixed look chosen from 27 styles. Licensed documentary stock footage suits finance, travel, business and news; footage mixed with AI images suits general facts; and AI images drawn in a fixed art style, such as stick figures, cartoon explainer, whiteboard, comic book, anime, 3D animation, claymation, classical painting or Greek statues, suit history, psychology and kids content. Any of those art styles can be fully animated with the Animate images option on videos up to two minutes. It also makes UGC-style product videos with AI actors.
EasyViral publishes its credit costs plainly: 250 credits for a 30-second video, 400 for 60 seconds and 700 for two minutes. Creator is $9 a month for 1,750 credits, which is about 4 one-minute or 7 thirty-second videos, even though the plan allows up to 2 a day. Growth is $24.99 for 5,000 credits (about 12 one-minute videos) and Studio $49.99 for 12,000 (about 30). Yearly billing saves 20%. Plan credits reset each month, while extra credits you buy never expire.
ShortFast's credits depend on the visual type. Typical costs from real videos in October 2026 are about 12 credits for a stock-footage video, 25 for an AI art-style video and 464 for a fully animated one. Starter is $19 a month for 1,000 credits, Pro $39 for 5,000 and Advanced $99 for 10,000, with 20% off yearly. So the honest answer is split: for fully animated AI video, EasyViral costs a fraction of ShortFast per video; for stock-footage or illustrated videos, ShortFast's entry plan makes ten to twenty times as many.
Both publish for you. EasyViral generates each video in a series and posts it to TikTok, Instagram or YouTube on the dates you pick, and runs several channels from one dashboard, with a daily cap of 2, 5 or 10 videos by plan. ShortFast runs 1, 3 or 6 automations by plan, each with its own timezone-aware schedule, and up to three posts a day per automation on Pro.
ShortFast also exposes the pipeline to code: a REST API, signed webhooks and an MCP server for Claude, Cursor and other agents, on the same plan credits. EasyViral mentions no API. Whichever you use, keep each video original: YouTube treats mass-produced, repetitive uploads as inauthentic content, and a niche template run unchanged every day is the pattern it targets.
