How we read and date each source

One term, one document

A definition on this site is never our opinion of a platform. It is what the platform itself writes in a public document: its terms of service, its help pages, its FAQ or its price list. Each term page quotes the passage, names the document and links to it.

Two dates on every source

Platforms rewrite their documents without notice. So every source shows two dates:

• the date of the document, as written in the document itself (often “Last updated”). For a help center article or a wiki page, it is the last edit date the help center or the wiki publishes for that page. When the document carries no date, the page says so. We never put the day we read it in its place;
• the date we read it, so you know how old our reading is.

When the live page could not be opened directly, we read an archived copy on the Wayback Machine and link to that copy as well.

When no platform defines a term

Some words are used everywhere on screen and defined nowhere in writing. When that is the case, the page lists the platforms and documents we checked, and the names we searched for, including the names a platform gives to its own features. A declared absence can be checked and challenged. A silent one cannot.

Prices

Prices come from the platform documents and are given in the currency the document uses, with its date. Quotes stay in the language of the document, word for word, typos included. Token prices change with the package you buy, so we give the range the document shows rather than one figure.

What we do not do

We do not rank platforms, we do not review performers, and no platform pays for a page. If a document changes or we got something wrong, the contact page is the place to tell us.
