How we review

This page explains which tools are listed, how the order of results is set and how we check reviews. The rules are the same for every tool. No vendor can change them with money.

Which tools are listed

We list a tool if it meets these conditions:

  • It is a product for companies that supports HR work.
  • It has an AI feature that the vendor describes on its website. We link to that page as a source.
  • The vendor's website is reachable and the information can be checked there.
  • It is not a general-purpose AI assistant that was not built for HR.

Every profile is based on the vendor's pages and on public sources that we name on the profile. We also use AI tools for research and writing. Nick is responsible for the content. The date "Profile checked on" shows when we last compared the profile with the vendor's website. We re-check profiles regularly, oldest first.

Anyone can suggest a tool. Suggestions are subject to the same conditions. Where a profile contains an assessment from an HR perspective, it is marked as opinion and does not count towards the stars.

What "Strong in a country" means

We only mark a country as strong if we find evidence for it, for example:

  • an office or legal entity in the country,
  • the product in the local language,
  • local payroll or integrations with systems that are common in the country,
  • a dedicated country page by the vendor,
  • reference customers in the country.

We state the reason on the profile. For each tool, we list the countries with evidence of strength in order, the most important first. "Available globally" means the tool is offered internationally, but we have not found evidence of particular strength in individual countries.

How the order is set

We disclose the main ranking parameters and their weighting as required by Section 5b(2) of the German Act against Unfair Competition (UWG).

The default sort order is "Relevance". It uses four parameters in a fixed order of priority:

  1. Country fit, only if you have selected a country: first tools where the country is among the first three countries with evidence of strength, then tools where the country is listed as strong further down, then tools that are available globally.
  2. Bayesian average of the reviews (explained below).
  3. Profile completeness: how many of the details are filled in, such as description, AI features, country fit with reasons, facts and sources.
  4. Name, alphabetically.

On weighting: a later parameter only decides if all earlier ones are equal. Country fit therefore comes before everything else. The Bayesian average decides within the same country-fit level, completeness only if the Bayesian average is equal, and the name only if everything else is equal.

The sort order "Rating" uses the Bayesian average only.

The Bayesian average stops a tool with a single five-star review from ranking above a tool with many good reviews. The formula is: (C × m + sum of all stars of the tool) divided by (C + number of its reviews). C = 3, and m is the average of all published reviews on ai-toolfinder.com. As long as no more than 30 reviews have been published in total, m is fixed at 3.8. Examples with m = 3.8: a single five-star review gives 4.1. Thirty reviews averaging 4.5 stars give 4.44. A tool without reviews sits at 3.8. All published reviews count equally, whatever their verification level.

The star average shown on a profile is the simple average. Because the order uses the Bayesian average, it can differ from the average shown.

Search terms and filters decide which tools are shown. The order follows the selected sort option. Payments, click counts, a claimed profile or invitations by vendors have no influence.

How we check reviews

As required by Section 5b(3) UWG, we explain whether and how we make sure that reviews come from people who have used the tool.

Nick reads every review before it is published. He checks whether it meets the review guidelines, whether own use is evident and whether there are signs of a conflict of interest. We do not check whether every single statement is correct. Reviews reflect the opinions of their authors.

Every review shows its verification level:

  • Email verified: the person signed in with a link we sent to their email address. This applies to every review. It shows that the person has access to this address, not that they have used the tool.
  • Work email verified: the email address belongs to a company domain and not to a free email provider. This suggests a professional background but does not prove use.
  • Use proven: Nick has seen a screenshot from the tool while signed in to it, or an invoice, and accepted it as proof. We delete the proof 30 days after the decision. This level exists if the function is offered.

Only the level "Use proven" shows that the person has used the tool. For the other levels, we check plausibility and conflicts of interest but cannot guarantee use.

Automatic checks support moderation:

  • The form rejects reviews from an email address at the domain of the reviewed tool, and a second review of the same tool from the same account.
  • The system flags addresses of competitors in the same niche and unusually many reviews in a short time for a closer look.

Reviewers confirm that the review is based on their own experience and that they have no connection to the vendor or a competitor. If a vendor invited the reviewer or there was an incentive, the review says so.

We publish negative reviews under the same rules as positive ones. Vendors cannot have a review removed just because they do not like it. We do not write reviews ourselves and do not buy any. To get the first reviews, Nick asks HR professionals from his professional network who use a tool for their assessment, without anything in return and without any requirements on the content.

Independence

ai-toolfinder.com is operated by Nick's Advisory. Nick advises companies on AI projects in HR. The directory is kept separate from this:

  • No vendor pays for being listed, for texts, reviews or the order of results.
  • At launch there are no paid placements and no affiliate links. The redirect to vendors only counts clicks.
  • If Nick's Advisory works for a listed vendor for pay, this is stated on that vendor's profile.
  • Should there ever be paid placements or affiliate links, we will label them visibly. Paid placements carry the label "Ad".

Reporting errors

If something in a profile is wrong, use "Report an error" on the profile or write to nick@nicksadvisory.com. Name the tool, the incorrect information and, if possible, a source. We check it, correct the profile and update the check date. Vendors can also take over their profile and suggest corrections directly, see For vendors. Please report illegal content via Report content.
