Soku AI

Free digital marketing tools, minus the fluff.

The working parts of a digital marketing stack — ad-math calculators, AI creative generators, SEO checkers, and free account audits. Built by Soku, free to use, most without a signup.

Audits & research

Start here: the fastest way to find money is an audit of what's already running — yours or a competitor's.

Ad-math calculators

Budgeting and measurement, answered with arithmetic instead of opinions: what ads cost, what a customer costs, and whether the campaign actually makes money.

CAC & CPA Calculator

Free acquisition cost calculator — switch between paid CAC and blended CAC, get CPA from spend and conversions, or work backwards from a target CPA to the conversions your budget must return.

Open tool
Ad Budget Calculator

Free ad budget calculator — back into the spend you need from a target number of customers (× CAC) or a revenue goal (÷ ROAS), then plan Facebook and Instagram spend from CPM down through CTR and conversion rate.

Open tool
Cost per Acquisition (CPA) Calculator

Free cost per acquisition calculator — get CPA from ad spend and conversions, or work backwards from a target CPA to the conversions your budget has to return.

AI ad creative

Creative volume is the biggest lever in paid social — these generate on-brand image ads, copy, and variants from a product URL.

AI video tools

Short-form video for Meta, TikTok, and YouTube — UGC-style ads, product videos, and editing utilities.

Script to Video

Free script to video AI from Soku AI — paste one scene of your ad script and get it back as a clip with the line actually spoken, because the audio is generated with the picture rather than laid over it afterwards.

Open tool
Remove Text From Video

Free video text remover from Soku AI — erase a watermark, a hard-coded subtitle or a stale price from a clip and get the frame rebuilt behind it, so you keep the full composition instead of cropping to hide a corner.

Open tool
AI Car Video Generator

Free AI car video generator from Soku AI — describe the car, the road and the light, and get a cinematic automotive clip back without a location day or a camera car. Then run it as an ad.

Open tool
Ecommerce Video Maker

Describe the product, the surface and the light, and get a short ecommerce ad clip back — no studio, no footage, no editor. Then test it as an ad across Meta, TikTok and Google.

Open tool
Real Estate Video Ad Maker

Paste a Zillow, Redfin, Realtor.com or brokerage listing URL — or upload up to 9 listing photos — and Soku AI writes and renders a vertical, ready-to-run listing ad: hook, on-screen facts, agent voiceover and CTA. Pick the listing event (just listed, open house, price change, sold), then open the cut on a canvas and launch it across Meta, TikTok, YouTube and Google.

Open tool
AI VFX

Upload a clip, name one effect — exploding gold coins, god rays, neon haze, electric arcs, sparkle — and get the same shot back with the effect on it, framing and camera move intact.

Frequently asked questions

What are digital marketing tools?
Software that helps plan, execute, and measure marketing: ad platforms and their calculators, creative generators, SEO and analytics utilities, and reporting tools. A working stack usually covers four jobs — research, creative, launch, and measurement.
Are these tools really free?
Yes. The calculators, generators, and checkers on this page are free to use, most without an account. The free ads audit and competitor analysis ask you to sign up so results can be saved to a workspace.
What digital marketing tools should a small team start with?
Start with measurement, not volume: a cost calculator to size the budget, one creative tool to keep ad variants flowing, and an account audit to catch wasted spend. Add tools only when a specific job is being done by hand every week.
How is Soku different from a folder of point tools?
The free tools each do one job. Soku the platform connects to your ad accounts and analytics and runs the jobs together — research, creative, monitoring, and client-ready reporting — with an AI analyst instead of a dashboard.

One workspace that runs the tools for you.

Soku connects to your ad accounts and analytics, then handles research, creative, monitoring, and reporting with an AI analyst.
