Our editorial method
What this publication establishes—and what it does not.
Vendor links in this edition are direct links. No paid placements are included. Comparisons describe published documentation, not hands-on test results. Commercial disclosure
Documentation, calculations, and opinion stay separate
Supplier capabilities and prices are attributed to published primary documentation. The buyer scenarios, page selection and fit rules are our editorial decisions. The calculators execute deterministic formulas against entered inputs. None of those categories establishes a hands-on supplier benchmark.
A bounded catalogue
This edition covers Useberry, Userbrain, Lookback and Maze. It does not claim to cover every vendor, all account configurations or every method. We choose a relevant question before a comparison and keep omitted scope visible.
The source date is not a permanent promise
The snapshot date records this research pass. Source publication dates can differ. Numeric prices retain the documented currency and billing period. A private quotation is not replaced with a guessed number. Legacy plan descriptions are not treated as current because another comparison repeats them.
How recommendations are formed
The tool picker filters documented method and audience routes, applies explicit commitment constraints and lists matches alphabetically. It does not assign a performance score or take a referral rate as input. Our writing can explain which route fits a stated task; it does not invent speed, accuracy, participant quality or test results.
Commercial independence
Editorial selection and commercial links are separate configuration. A direct vendor link works without affiliate approval. A configured affiliate link is labelled and qualified. No brand has purchased its position in this edition.
Reporting a correction
Each guide links its primary evidence. A correction should identify the page, the claim and the newer authoritative source. This publication has no public file-upload facility; do not send participant recordings or private customer documents as evidence of a pricing correction.
