Primary sources first
Facts come from official homepages, help centers, pricing pages, app listings, terms, and privacy notices. Article source lists link directly to those documents rather than an unrelated referral destination. Volatile details are linked to live sources instead of presented as permanent.
Useful comparison, not a universal winner
Every verdict is attached to a use case, tradeoff, and repeatable test. We separate provider claims from independent analysis.
AI-assisted workflow
This publication uses AI-assisted research and drafting under the site owner’s direction. Comparisons are source-informed editorial analysis. Suggested exercises are not measured tests, and we do not publish invented usage results or customer testimonials. Corrections should include the relevant primary source.
Corrections
When the contact mailbox is configured, send the page URL, disputed passage, and current primary source. Material changes update the article and its structured modification date.
