Yansu, from Isoform, flips that contract: it watches how work actually gets done, learns the pattern, and builds the automation from observation rather than instruction. The vendor describes autonomous loop-based execution across desktop tasks, support ticket handling, and form-filling — with a local-first processing model that keeps data off third-party servers. Teams capturing tribal knowledge get the most direct value here; the agent surfaces patterns that live in no documentation. The ceiling appears when workflows require branching logic or cross-system integrations that go beyond what observation can infer, at which point teams are back to configuring manually. No public API is available, which limits how far this plugs into existing engineering stacks.
