Free UGC ad tools
These are 11 free browser tools for the work that happens before you render an ad: writing the hook, writing the script, building a model prompt, and doing the arithmetic on what a testing round costs and what it has to return. No signup, no credit card, and no usage caps beyond basic abuse protection.
They fall into three groups. Writing tools draft the creative: the UGC hook generator gives you a batch of opening lines to test against each other, the UGC script generator turns a product into a 30-second script structured the way UGC ads actually run, and the ad copy checker scores copy you already have against what works on paid social. Prompt and model tools handle the technical side: the Veo 3.1 and Sora 2 prompt generators build a structured prompt with subject, camera, lighting and dialogue instead of a vague sentence, and the AI video model picker asks four questions and tells you which model fits the shot, with real credit costs. Calculators cover the money: the UGC cost calculator prices hired creators against AI UGC at your monthly volume, the break-even ROAS calculator finds the return your ads need before they make money, the ad testing budget calculator plans variants, daily budget and days to spend, and the ad metrics calculator turns raw spend and results into CPM, CPC, CTR, CPA and ROAS, and the AI video price index lists what one ad costs to render on each model, in credits and in dollars on every plan.
Who they are for: ecommerce owners and media buyers who need something usable in the next ten minutes, agencies scoping a client testing plan, and anyone comparing AI UGC tools who wants to see how we think before paying for anything. They work standalone, so you can use the script generator and shoot the ad yourself, or paste a prompt from here into whichever video tool you already run. The full multi-model video generator is the paid product; these stay free.
All free tools
Every tool runs in the browser. Nothing here asks for an account.
How to use them together
The tools are sequenced, even though each one works alone. A normal run through looks like this. Start with the break-even ROAS calculator so you know what a winning ad has to do before you make one. Use the testing budget calculator to decide how many variants that budget supports, because that number determines how much creative you need.
Then write. Pull a batch from the hook generator, keep the three that fit your product, and run each through the script generator. Put the result through the ad copy checker before you spend anything rendering it. Pick the model with the model picker, build the prompt with the matching prompt generator, and once the ads are live, feed the numbers back into the ad metrics calculator to see which hook earned another round.
When the free tools are not enough
These stop at text. They will write the script and tell you which model to use, but they do not render video. When you want the finished ad, that is the paid product: one credit pool that spends across Veo 3.1, Sora 2, Kling, Seedance, OmniHuman 1.5, Grok and Happy Horse 1.1, with 9:16, 1:1 and 4:5 MP4 output, burned-in captions, and no watermark on any plan. Plans start at $49/mo for 5,000 credits, and there is no cap on the number of videos you make; you simply spend credits. See pricing for the tiers and top-up packs.
The trial is free for 3 days. Licensing, credits and billing questions are answered on the FAQ. If you are still choosing a tool, the alternatives pages compare us with Arcads, Creatify, HeyGen, MakeUGC and Synthesia, the comparison guides cover format and model decisions, and the industry pages have the version written for what you sell.
