Frequently asked questions

How do tools get listed on CitedIndex?

Each listing is a researched record that must pass an automated quality gate (a minimum of structured fields, sourced facts and an on-topic fit-check) before it can be published. Thin pages are structurally impossible.

Is CitedIndex free to use?

Yes. Browsing and searching the directory is free, and submitting a tool is free too. Every submission goes through the same research pipeline and quality gate.

Can a tool pay for a better rank?

No. Rankings and verdicts are editorial and the quality gate is never for sale. What tools can buy is clearly-labelled placement (Featured spots, sponsored slots and digest sponsorships), which never changes what our research says about them.

How fresh is the data?

Every listing is re-researched on a schedule, and each fact carries the source it was verified from, with the verification date printed on the listing. Changes land in the listing changelog, not silently.

What do the scores mean?

The editorial score summarises our researched verdict across capability, coverage and value. How we weigh those is public on the methodology page. Scores move when re-research finds real changes.

I built a tool. How do I get it covered?

Submit it free. The research agent builds a sourced listing, the quality gate checks it, and if it fits the taxonomy it publishes. You claim it from your inbox and manage it (including upgrades) from your dashboard.
