Engineering teams shipping with AI have a new bottleneck: validation. Code output has accelerated. Quality hasn't. Checksum closes the gap.
Checksum is a continuous quality platform with a suite of AI agents that handle testing end-to-end, at every stage of the development lifecycle. Where most tools wait for a human to trigger them, Checksum runs autonomously in the background, generating tests, executing them, and repairing failures without manual intervention. Seventy percent of test failures are resolved automatically through real-time auto-recovery.
The platform covers every layer: end-to-end UI flows via Playwright, API endpoint chains, and targeted CI tests scoped to exactly what changed in a PR. All tests land as real code in your repository and are delivered as standard Playwright, owned by your team.
Checksum is fine-tuned on 1.5+ million test runs and integrates natively with Cursor, Claude Code, and 100+ AI coding agents. Type /checksum and your coding agent's output gets tested before it ever reaches review. Generation and healing happen on Checksum's cloud infrastructure which means no LLM tokens consumed, no local resources required.
The result: test suites that stay green as the product evolves, fewer regressions reaching production, and release confidence that scales alongside AI output.

PearAI
Incorporating questions or generating code within the context of your codebase can yield precise outcomes, enhancing your work with specific folders, online documentation, terminal output, and files. PearAI enables direct coding in your projects while providing visibility into the differences through diffs. For instance, by using CMD+I (or CTRL+I on Windows), you can request PearAI's assistance in implementing error handling and adding comments. Remarkably, without writing any code ourselves, we successfully introduced a new feature to the unfamiliar codebase by creating a documentation page for the PearAI landing site. This approach can significantly accelerate your development process by integrating AI smoothly into your daily tasks. The primary aim of PearAI is to shorten the journey from concept to implementation. As coding remains an essential element of product development, we anticipate that advancements in AI will profoundly transform this landscape in the foreseeable future. Our mission is to cultivate an environment that embraces these transformative changes, addressing both immediate needs and future developments as they arise. As technology evolves, we aspire to keep pace with innovations that will reshape the way developers work and create.
