How we research
- We collect each product's facts from its official website, pricing page and help documentation, and record where we found them.
- Origin, platforms, free options and features are checked against those official sources before an item is listed.
- Software prices are re-checked automatically every day where the pricing page allows it, and every change is logged.
- Rankings come from the data: well-known direct replacements first, then the closest matches by shared features and platforms. Commissions never change the order.
- We only list legal services. Health topics are information only and always point you to a licensed clinician.
- Star ratings come only from reviews by registered users. We never invent ratings or reviews.
