The Vannus catalog — 373 AI tools, graded on resilience.
Every tool is graded A+ through F on whether it builds its own AI or is a thin reseller of another company's model. For 253 tools, the grade traces to the vendor's own published documentation — so you can check the claim at the source. A further 97 were established to run no foundation model at all, so there is nothing to cite — that is an answer, not a gap. For the remaining 23 the product uses AI and the vendor does not name the provider, and the entry says exactly that rather than a guess. We do not claim to know which without having looked. We are not aware of another directory that publishes the source behind each grade; if you find one, tell us and we will say so.
Tiers track the grade: Sovereign (A), Durable (B), Moderate (C), Fragile (D), Wrapper (F — a thin layer over a foundation model with limited differentiation). Grading weighs nine trust dimensions including data sovereignty, training privacy, compliance posture, and operational resilience. No paid placements, no popularity boosts — scoring is architecturally walled off from affiliate revenue.
A tier is a claim about what a product runs on, so we withhold it rather than guess. Where provenance was never established we say Provenance not established; where the evidence contradicts the computed tier — a multi-model provider landing in Wrapper, say — we publish the grade and say Tier withheld. Tools with no commercial vendor behind them are Not rated, because the resilience questions do not apply to them.
