Checksum.ai
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.

Synthetic Users
Synthetic Users is an innovative platform that leverages AI to facilitate user research by employing sophisticated natural language processing and large language models to create synthetic personas that closely resemble authentic human behavior, achieving a high degree of "synthetic organic parity." This capability enables teams to swiftly establish research objectives and conduct virtual qualitative and quantitative studies—such as in-depth interviews, concept testing, problem exploration, tailored scripts, or surveys—in mere minutes instead of the typical weeks required. Additionally, the platform generates detailed personality profiles for each synthetic participant and utilizes a multi-agent framework to replicate dynamic, context-sensitive conversations and decision-making processes that reveal valuable product insights. This process aids in validating concepts, refining user experiences, prioritizing development roadmaps, and examining behaviors across a wide range of audiences. Moreover, users have the option to enhance their simulations with proprietary data, thereby improving the relevance of the insights and ensuring a more accurate representation. By integrating these features, Synthetic Users empowers teams to make informed decisions swiftly and effectively.
