How We Test and Rate AI Tools
Last updated: 20 August 2026
Most AI tool directories give you a number and no explanation. Ours is meant to be checkable — you should be able to look at any score on this site and verify it yourself in about five minutes.
First, what we honestly do and don’t do
We do not hands-on test every tool on this site. There are hundreds of them and that claim would be a lie. Anyone who tells you otherwise about a catalogue this size is not being straight with you.
What we do instead:
| Every listed tool | Compiled from primary sources — the vendor’s own site, pricing page, documentation and public launch materials. Never rewritten from another directory. |
| Every score | Based on published, verifiable criteria (below). No subjective “ease of use” numbers we cannot defend. |
| Reviewed tools | The tools with a full review article at /review/ are used hands-on. Those articles say so explicitly and are signed. |
| User ratings | Come from actual visitors, kept separate from our editorial score and never averaged into it. |
The Toolvern Score
Six dimensions, 0–5 each. Every one is checkable from public information.
1. Pricing transparency Are actual prices published? A page with numbers and limits scores 5. “Contact us for pricing” with nothing else scores 0. This matters more than people admit: opaque pricing usually means the price depends on how much they think you can pay.
2. Free access Free plan with a usable limit scores 5. Time-limited trial scores 3. Card required before you can see anything scores 1. Nothing at all scores 0.
3. Integrations How many documented, first-party integrations exist with the tools a marketing team already runs — CRM, analytics, CMS, ad platforms, automation. Counted from the vendor’s own integrations page, not from marketing claims.
4. Developer access Public API with real documentation scores 5. API on request scores 2. No API scores 0.
5. Support and documentation Documented support channels, response commitments, and whether the docs actually explain the product rather than repeating the landing page.
6. Track record How long the product has existed, whether it still ships updates, and whether the changelog or blog shows signs of life in the last six months.
What we deliberately do not score: output quality. Judging whether one AI writer produces better copy than another, across hundreds of tools, in a way that is fair and reproducible, is not something we can honestly claim to do. Where we have tested output, it is in a signed review, not a number.
Pricing data
Prices are read from the vendor’s own pricing page and recorded with the date we checked. Every tool page shows that date.
We re-check pricing quarterly, and immediately whenever someone reports a change. If a figure on this site is stale, the date will tell you.
Vendor claims are labelled as vendor claims. If a company says their tool increased someone’s traffic by 800%, we attribute that to the company. We have not verified it, and neither has any other directory that repeats it as fact.
What gets listed
We list tools that are live, functional, and belong to the marketing and sales cluster this directory covers.
We decline: dead or abandoned products, tools that misrepresent what they do, thin wrappers with no product behind them, duplicates, and anything adult or illegal.
A tool being unknown is not a reason to decline it. A tool being large is not a reason to rank it higher.
Categories
Every tool sits in at most four categories. This is a hard limit in our database, not a guideline.
The reason: a tool listed in twenty categories makes all twenty categories useless. Directories that let vendors self-select unlimited tags end up with category pages that are just the whole catalogue in a different order.
Corrections
Every tool page has a correction link. If the pricing is wrong, a feature is missing, or we described something inaccurately, tell us — corrections are published and the check date is updated.
We would rather be corrected than be quietly wrong. Write to support@toolvern.com.
Does paying change any of this?
No. Payment affects when a listing is published and whether the outbound link is followed. It does not affect the score, the position in category listings, or what we write.
