Decision Mentor is a decision-support platform built on the Analytic Hierarchy Process, the pairwise-comparison method developed by Thomas Saaty. It has three engines: Scorecard and Rubrics rate options on weighted 1 to 100 scales with automatic aggregate scores; Side-by-Side Compare builds pairwise trade-off matrices on Saaty’s 1 to 9 scale and checks the consistency ratio in real time against the usual 0.10 threshold; and the AI Decision Mentor turns a natural-language description into a criteria hierarchy and rating scales. It runs on the web, iOS and Android with sync between them.
The design principle is stated on the homepage: AI is good at brainstorming and automating routine work, but final trade-off choices are a human responsibility. That is the right division for a language model here, because it drafts the criteria and structure while the person supplies the judgments that the mathematics then aggregates and tests for consistency. The site lists more than 20 publications, including Springer, Routledge and MDPI items and ISAHP symposium papers; check how directly they concern this product rather than AHP in general, since the pages reviewed show no user counts or ratings.
The free plan allows up to three active personal decisions with standard pairwise comparisons, the mobile apps and a public community feed. Pro Mentor is $4.99 a month and adds unlimited decisions and hierarchy levels, interactive mind maps, AI Mentor chat and PDF and presentation exports, so the AI chat sits behind the paid plan. An Enterprise edition for portfolios of 100-plus project proposals adds group consensus scoring, sensitivity modelling, ERP sync, SSO and an SLA. The site names Truenary Solutions and Development Dynamics as operators and gives no founding year.
