Four classes of agent. One curated substrate. Odahl is a constellation of small minds — Cardinal, Proper, Minor, Minima — each tuned for a different depth of thought, all sharing one memory you actually own.
Each class earns its keep. The same substrate underneath. One subscription, all four.
Every conversation extracts nodes — small, atomic facts about you, your work, your beliefs. They link, reinforce, decay. They're encrypted. They're yours.
Triple nodes (subject-predicate-object) and quad nodes (second-order claims about claims). Inter-sentence inference connects across paragraphs.
Seven-dimension audit. Weak nodes are pruned. Strong nodes are promoted. A daily score keeps the web honest.
For each public-knowledge node, Wellie searches the open web and returns support, contradict, or neutral with citations.
Substrate is portable. You can leave with a single JSON dump — nodes, edges, scores, history — at any time, no friction, no fees.
The first generation of AI treated memory as a feature — bolt-on, switch-off, summarise. We think memory is the thing. Everything else is decoration.
A small system run with care beats a large system run carelessly. We optimise for honesty, for latency, for what actually ships — not for the most impressive demo.
No usage anxiety. No hidden ceilings. No surprise bills. Cancel any time, export your substrate on the way out. We outlast hype cycles.
Sign up free. Try Minor and Minima at no cost. Move up to Proper or Cardinal when you're ready. We don't trick people into upgrades.
