How We Rate AI Tools
Our scoring methodology is 100% transparent. No vendor payments influence our ratings.

Why This Matters
AI tools are evolving faster than any software category in history. What was state-of-the-art three months ago may already be outdated. We weight output quality and accuracy at 30% — nearly double any other criteria — because an AI tool that gives wrong answers quickly and cheaply is worse than no AI at all. Getting reliable, truthful results is the foundation everything else builds on.
Scoring Weights for AI Tools
Every AI tool is scored across six criteria. Output quality receives the highest weight because accuracy and reliability are the non-negotiable foundation of any useful AI tool.

How We Test AI Tools
We use a standardized prompt battery of 50 tasks across 8 categories: factual Q&A, creative writing, code generation, data analysis, summarization, translation, reasoning problems, and multi-step instructions. Each AI tool receives the identical prompts so comparisons are directly meaningful.
Accuracy is verified against ground truth. For factual questions, we check answers against authoritative sources. For code generation, we run the output and verify it compiles and produces correct results. For reasoning tasks, we use problems with known correct solutions. We track hallucination rates as a percentage of responses that contain fabricated information presented as fact.
Speed testing measures wall-clock time for both short responses (under 100 tokens) and long responses (1,000+ tokens). We test at different times of day to account for load variations. We also measure time-to-first-token for streaming APIs because perceived responsiveness matters for interactive use.
Privacy evaluation involves reading the complete terms of service, data processing agreements, and privacy policies. We verify whether data submitted through the API is used for model training, how long conversations are retained, and what compliance certifications each provider holds. For enterprise use, data handling is not optional — it is a dealbreaker.
What We Don't Do
- ✗We don't accept payment from AI companies to influence scores or rankings
- ✗We don't use affiliate commission rates to decide which AI tool wins a comparison
- ✗We don't aggregate benchmark scores from other sources — we run our own standardized tests
- ✗We don't cherry-pick impressive examples — we report average performance across all test prompts
- ✗We don't rely on vendor-published benchmarks — our tests use real-world tasks, not academic datasets

Update Schedule
This methodology was last reviewed: April 2026. Due to the rapid pace of AI development, we re-evaluate our AI scoring criteria monthly — not quarterly like other categories. Comparisons are updated whenever major model updates are released, ราคา changes, or new capabilities become available.
