AstronovAI compares tools using verified profile fields such as category, primary use case, pricing model, trial status, ratings, pros, limitations, and editorial review status.

We compare the main use case and target context of each tool before assigning any recommendation.
Tools must pass content verification checks before they appear in public comparisons.
Scores are treated as one signal, not as a replacement for feature and use-case review.
Paid or Featured placement does not improve organic comparison ranking, and verification is shown as a trust fact rather than an approval or ranking bonus.
