Official sources are the default
We prioritize the vendor's own website and documentation for vendor-controlled facts. The source should identify the same product and support the specific field being reviewed.
- Product and plan pages
- Help centers and technical documentation
- Security and privacy pages
- Official announcements and terms
Fields are checked individually
A reviewer may check product positioning, pricing model, free access, trial availability, platforms, integrations and core capabilities. A field is not filled merely because a similar product normally offers it.
Unknown is different from no
If a free plan, trial, integration or price cannot be confirmed, the correct status is unconfirmed—not automatically no. This distinction prevents missing research from being presented as a negative product fact.
Pricing needs extra caution
Displayed prices may exclude taxes, annual commitments, required add-ons, minimum seats or usage charges. Contact-sales products may not publish a usable starting price. Readers should confirm the final plan, billing unit and renewal terms before purchase.
Verification dates have a limited meaning
The last-verified date records when the cited information was reviewed. Vendors can change details after that date, so older records and high-impact claims receive priority during maintenance.
Corrections are evidence-based
When a reader or vendor reports an error, we compare the claim with official material, update the affected field when supported and refresh the review date where appropriate. Requests to change editorial judgments are considered but are not accepted solely because a product disagrees with a conclusion.
