About 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.		About NovaSynth is a web-based platform for testing voice and chat AI agents. Developers and QA teams connect an agent through a phone, LiveKit, or HTTP Chat connection, then define synthetic caller personas and conversation scenarios. Single or batch runs can exercise interruptions, background noise, accents, and other edge cases. NovaSynth records sessions and traces, with transcripts and evaluation results teams can review to identify failures and compare runs after agent changes. It supports evaluation and regression testing before and after deployment. Usage is credit-based: the free plan includes 2,500 credits per month, and Pro starts at $69/month with 10,000 credits. Voice calls use 100 credits per minute, text conversations use 12 credits each, and evaluation may consume additional credits. Teams need an account and a configured, reachable agent connection for testing.
