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.

The collaboration layer for AI engineering teams
Edit, version, diff and roll back prompts from a visual dashboard with no coding, so product, marketing and content teams can iterate on prompts while engineers keep control of the deploy.
Run dataset-backed tests with human and AI graders, trigger regression evals whenever a prompt changes, backtest new versions against historical data and compare prompts across models.
Connect production traces to the exact prompt version that produced them and inspect failures, cost, latency and token usage by feature, model or user.
Build, trace and improve agent workflows with prompts, tool calls, evaluations and logs in one place, so multi-step runs can be tested before they ship.
