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.

Work is broken because your tools are. Dozens of apps, zero shared context, your team stuck playing messenger between all of them. That's not collaboration. That's overhead. ClickUp eliminates the mess. One platform: tasks, docs, chat, goals, time tracking, whiteboards, and AI Agents that work autonomously while you sleep. Everything shares one connected brain. No silos. No duplicated effort. No lost threads. Manage any workflow with custom views, automations, and real-time collaboration baked into every layer. 15+ views including List, Board, Gantt, Timeline, and Calendar. Create rich documents with nested pages and embedded tasks. Set measurable goals with automatic rollups that connect daily output to company objectives. Track time natively with timers, estimates, and workload views that prevent burnout. Over 1,000 integrations plug into your existing stack without adding chaos. GitHub, Slack, Google Drive, Figma, Salesforce, Zoom, and hundreds more — all feeding into one system of record. Built-in AI writes, summarizes, and executes entire workflows on its own. Not a bolt-on — native intelligence woven through every feature. AI Agents handle complex multi-step work around the clock without waiting for humans. SOC 2 Type II certified. SSO/SAML. Custom roles. Audit logs. Scales from five people to fifty thousand. Stop patching a broken system. Start free today. No credit card, no commitment.
