Every tool on CompareMyAI receives a score out of 10. This page explains exactly what goes into that number, how the weights work, and what a score does — and doesn't — tell you.
What a score is
A score is a structured comparison of publicly available facts — not a hands-on review, not a personal opinion, and not the result of lab testing. We gather data from each tool's official pricing pages, documentation, security certifications, and terms of service. That data is run through a consistent formula applied identically to every tool.
Two tools scoring 8.3 and 8.1 are genuinely close. A small score difference reflects a small difference in the underlying data — not a definitive verdict. Your best choice depends on your specific needs, which is why we show you the full picture alongside the score.
Scoring criteria
Five criteria make up the score. Each is weighted to reflect how much it typically matters to users comparing AI tools for real-world use.
Pricing and value
25%We compare published pricing tiers in GBP across all tools in the same category. We look at what each tier actually gives you — usage limits, feature access, and whether a meaningful free tier exists — not just the headline price.
Features and capabilities
20%We record whether each tool offers API access, a mobile app, a browser extension, third-party integrations, and the breadth of use cases it supports. These are taken from the tool's official feature documentation.
Security and compliance
25%We check each tool's published compliance status: GDPR compliance, SOC 2 certification, and ISO 27001 certification. These are independently verifiable from official documentation and vendor trust pages.
Data handling and training policies
15%We record whether a tool trains on user data by default, whether opt-out is available, and whether a Data Processing Agreement (DPA) is provided. All data comes from the vendor's published privacy policy and terms of service.
Transparency and trust signals
15%We look at whether MFA is supported, whether enterprise SSO is available, and how clearly the vendor communicates its data practices to users. Clarity of disclosure is itself a signal worth capturing.
What scores don't do
- Reflect hands-on testing or qualitative judgement
- Account for personal workflow preferences
- Capture every edge case or niche use
- Replace reading the full tool profile before deciding
Affiliate relationships have no effect on scores. A tool we earn a commission from is scored identically to one we earn nothing from. The formula is fixed; the data determines the number.
When scores are updated
Scores are recalculated when a tool's underlying data changes — a pricing update, a new compliance certification, or a change to the tool's data handling policy. Every tool shows a “last verified” date. If the data is more than 30 days old, we flag it so you can check before making a decision.
