Comparison Methodology

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

Pricing

We show the listed pricing model and avoid treating unknown fields as confirmed offers.

Use Case Fit

We compare the main use case and target context of each tool before assigning any recommendation.

Profile Quality

Tools must pass content verification checks before they appear in public comparisons.

Score Signal

Scores are treated as one signal, not as a replacement for feature and use-case review.

Ranking independence

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.
