About Agent Assurance by TestMu AI
Agent Assurance by TestMu AI tests how your AI agents actually behave across workflows, tools and actions, so failures are caught before they ship. Point it at an agent you own and it reads the codebase, a PRD or policy docs, writes functional and adversarial scenarios, invokes the real agent, and grades every criterion against observed evidence: files changed, artifacts produced, and tool calls checked against the agent's declared tools. Verdicts are Pass, Fail or Unable to Verify, and the third is kept out of the pass rate. Built for agents that act, such as coding, workflow and back-office agents, it runs from the terminal with the Rook CLI and headless in CI.

SmartUI
SmartUI by TestMu AI is a visual testing tool for web pages, mobile apps, Figma designs and PDFs. It captures screenshots and compares them with approved baselines to catch layout, color and font bugs that functional tests miss. Visual AI filters anti-aliasing and font-rendering noise, Smart Ignore skips ads, timestamps and content that only moved, and each remaining change is labelled by type and severity. Smart RCA explains why the UI broke, next to the diff. SDKs cover Selenium, Playwright, Cypress, Puppeteer, Appium, Espresso and XCUITest, and a CLI handles Figma and Storybook. The free tier includes 2,000 screenshots.

Agent Testing by TestMu AI
Agent Testing by TestMu AI tests chat, voice, phone (inbound and outbound), video and image agents before and after release. Upload a PRD, knowledge base or short description, or connect Jira and Confluence, and it generates 60 to 100+ scenarios across happy paths, edge cases and adversarial inputs. 15+ specialized AI evaluators then hold real conversations with the agent and score every response for hallucination, bias, toxicity and compliance gaps. Chat and voice agents are scored on 9 quality metrics and phone agents on 30+ call metrics. The result is a Green, Yellow or Red go-live verdict with a confidence level.

Checksum.ai
Checksum is a continuous quality platform that autonomously generates, runs, and maintains tests so engineering teams can ship AI-generated code without trading speed for reliability.
Unlike copilots that wait for prompts, Checksum works as a background agent, detecting what needs testing, generating production-ready Playwright, and healing broken tests automatically. Seventy percent of failures resolve autonomously, keeping suites green without manual effort.
Built on fine-tuned data from 1.5+ million test runs, Checksum covers every layer of the SDLC: end-to-end, API, and CI testing from a single platform. Tests are delivered as standard Playwright code, submitted as a PR to your repo. No vendor lock-in.
Checksum integrates natively with Cursor, Claude Code, and 100+ coding agents via /checksum slash commands, so code is tested before a human ever reviews it. AI handles generation and healing on Checksum's cloud: no LLM tokens.
The result: ship faster, with confidence.
