A studio for your mind: object-based notes that stay connected
Model people, books, projects and meetings as typed objects with their own properties, instead of forcing them into folders.
See every link to a note at a glance, and let Capacities surface unlinked mentions where you already wrote about the same thing.
Capture thoughts without deciding where they belong first, then link and refine them later.
On paid plans, an AI assistant works alongside your notes, and image, PDF and weblink analysis turns outside material into usable content.
GenAI-native end-to-end QA agent that plans, writes and heals tests in plain language
Feed KaneAI text, tickets, docs, diffs, images or media and it drafts scenarios and test cases automatically.
Written steps describe intent rather than selectors, so the tests remain readable to non-engineers.
Authored tests convert into runnable automation for web and mobile, executed at scale on the cloud grid.
Intent-based steps and AI-based error classification reduce flakiness and false failures as the UI evolves.
