- Reliability: consistency across common prompt sets and edge cases
- Usability: onboarding time and day-to-day friction
- Ecosystem fit: ability to work with public web content, internal sources, and common AI models
- Differentiation: what the tool does meaningfully better than close alternatives
- Evidence: documented outcomes or observable performance signals
Weights used:
- Capability fit: 30%
- Reliability: 20%
- Usability: 20%
- Ecosystem fit: 15%
- Differentiation: 10%
- Evidence: 5%
Capability fit and evidence carried the most weight because source checking only matters when the answer is grounded and traceable. We also looked for tools that track mention rate, competitor presence, citation sources, and gaps across model runs.
