Free tools for digital product sellers
Working tools, not lead magnets. No signup wall, no "enter your email to see the result", no PDF in your inbox. I needed each of these while running this shop and figured you might too. If one of them saves you a bad pricing decision, browse the catalog on your way out — that is the whole business model.
// pricing math
What should I charge?
Pricing a digital product is three answerable questions, not a feeling. This calculator turns product type, audience, and depth into a defensible price band — then shows monthly revenue with platform fees already subtracted.
// legal plumbing
Is my refund policy actually compliant?
Digital products follow different refund law than t-shirts: the EU withdrawal right ends at download, dual consent makes it stick, and from 19 June 2026 a withdrawal button is mandatory. This wizard writes the policy text that matches.
// ai visibility
Can AI search engines read and cite my site?
Two five-minute checks: whether the 12 AI crawlers that matter can access your pages at all, and whether you hand them a curated map once they arrive.
// editorial quality
Does my copy read human?
Five measurable style tells separate machine-flat prose from writing people trust: em-dash density, stock phrases, triad padding, sentence rhythm, first-person voice. The same rules gate this site’s own copy before publish.

What do platform fees actually eat?
Every marketplace quotes its fee as one tidy percentage. The real cut is layered: platform fee, fixed cents, card processing, marketplace surcharges. These calculators itemize all of it — fee tables carry a visible verification date.

What lands next
The calculator family shipped in June 2026 with numbers verified against official pricing pages — I would rather ship eight tools with checked figures than twenty with stale ones. The build queue from here, in order:
- · GEO score checker — paste a URL, get a citability score (wave 2, pending traffic data)
- · Schema (JSON-LD) generator suite for product pages (wave 2, pending traffic data)
Want one of these sooner, or need a tool that is not listed? Tell me at support@toolgenx.com — requests genuinely reorder the queue.
// where these come from
Several of these tools are a chapter from a book
The AI Crawler Checker, the writing checker, and the pricing math each run a method from the five short Solo Operator books. The tools above stay free with no signup. If you want the reasoning behind one, read the book, or grab its free printable workbook (that one takes an email).
