Free tools
for UGC creators & video marketers

How these tools fit together

Every tool on this page runs in the browser, needs no account, and keeps whatever you type on your own machine. They exist because the same handful of questions come up on every short-form campaign: how long should this script be, will the caption survive the safe zone, what does a click actually cost, and is this creative paying for itself yet. Each one answers a single question and links to the next step rather than trying to be a suite.

Before the shoot

Start with the video hook generator to get openings worth testing, then the creative brief generator and UGC storyboard generator to turn the winner into something a creator can actually shoot. The script length calculator converts a word count into runtime at a realistic speaking pace, which is the fastest way to find out that a 30-second script is really 48 seconds.

Sizing and delivery

The aspect ratio calculator and social video specs cover the resolutions, ratios and safe zones for TikTok, Reels and Shorts, so one shoot ships to three placements without a re-crop or a caption sitting under the UI.

After it is live

The CPM, CPC, CPA, CTR, ROAS and break-even ROAS calculators turn spend, clicks and conversions into the numbers you actually report on - including the one that decides whether to keep spending, which is the ROAS you need to clear your margin rather than the one you got. The A/B test calculator tells you how much traffic a creative test needs before the winner means anything.

When the planning is done and you need the ad itself, Creetr turns a product link into a finished UGC video with an AI actor. The guides cover how the main AI video tools compare and what each one costs per finished ad.
