How we picked
Every one of these AI video generators is scored by the same 8 criteria (scorecard v2). Each criterion gives 0 to 100 from the vendor's published data; the total is the weighted average. A criterion without verified data is left out and the other weights are re-normalised. A tool with under 60% of the weight covered is listed as not ranked, and so is a tool with no verified price and fewer than 2 verified features (“needs a verified price”); each score shows how many criteria it is based on. The core criteria are the same in every category; the category criteria are specific to AI video generators. Nobody gets custom weights, including our own products.
| Criterion | Weight | Type | What we measure |
|---|---|---|---|
| Entry price | 25% | Core | Price per month of the cheapest paid plan, against the prices of other AI video generators on the same billing basis (monthly-billed prices against monthly, annual-billed against annual).Log scale. Billed monthly: $9/month or less = 100, $39 or more = 0. Only billed annually: $4.50/month or less = 100, $25 or more = 0. Only free plans = 100. Usage-priced and one-time plans are not scored. |
| Free plan or trial | 15% | Core | Whether you can use the tool before paying: a free plan, or failing that a free trial, as shown on the vendor's pricing page.Free plan = 100. No free plan but a free trial = 60. The pricing page lists plans but shows neither = 0. No plans read = not scored. |
| Pricing transparency | 10% | Core | How much of the pricing is public: the share of plans with a published price ("contact sales" counts against), and whether there are at least 3 published tiers.80 x (plans with a public price / plans listed) + 20 x (public plans, up to 3) / 3. No plans read = not scored. |
| Verified features | 15% | Core | How many of the 8 features we track for this category the vendor's own pages verifiably show (text to video, ai avatars, voice cloning, automatic captions, ai dubbing / translation, 4k export, no watermark on paid plans, brand kit). This counts verified features only: a tool that documents less scores lower here, and only here.Linear: verified features / 4 (half the tracked list) x 100, capped at 100. No tracked feature verified = not scored. |
| API, integrations and export | 10% | Core | Whether a public API exists, how many integrations the vendor states, and whether the vendor documents a way to export your data.Average of the parts with data: public API yes = 100, no = 0; integrations on a log scale (50 or more = 100); a documented data export = 100. None verified = not scored. |
| Cost per video minute | 10% | Category | Price per video minute on the cheapest paid plan that states a monthly minutes limit (monthly price / allowance).Log scale: $0.50 per video minute or less = 100, $10 or more = 0. Unlimited or unstated allowances = not scored. |
| Languages | 10% | Category | Number of languages the vendor says it offers.Linear scale: 100 or more = 100. No stated count = not scored. |
| Avatar library | 5% | Category | Number of stock avatars the vendor says it offers.Linear scale: 200 or more = 100. No stated count = not scored. |
