AI coding tools have fundamentally changed how software gets built. Developers are shipping more code, faster, with less friction than ever before. But the organizations benefiting most from AI-accelerated development are running into the same wall: quality hasn't kept pace.
More code means more surface area for bugs. More PRs means more review burden on senior engineers. More releases means more chances for regressions to reach customers. The bottleneck has moved from writing code to verifying it, and verification is still largely manual.
Checksum is a continuous quality platform built for this reality. Its suite of AI agents autonomously generates, runs, and maintains tests across every layer of the software development lifecycle: end-to-end UI flows, API endpoint coverage, and PR-level CI validation, so engineering teams can move fast without sacrificing reliability.
What sets Checksum apart: it doesn't wait for instructions. It works as a background agent, continuously monitoring your codebase, generating tests for what matters, and repairing broken tests as the product evolves. Seventy percent of test failures resolve automatically, eliminating the maintenance burden that causes most test suites to decay and get abandoned.
Every test Checksum produces is real, Playwright code you own, submitted as a PR to your repository. No vendor lock-in. Teams keep full control.
Checksum is fine-tuned on 1.5+ million test runs and integrates natively with Cursor, Claude Code, and 100+ AI coding agents via /checksum slash commands. Testing happens before code review, not after. Generation and healing run on Checksum's cloud, consuming no LLM tokens or local resources.
The bottom line: Checksum gives engineering teams the confidence to ship at the speed AI makes possible.

Caret
Caret brings exceptional text editing features to Chrome OS by utilizing the powerful Ace editing component. This innovation allows users to avoid the complexities of installing a different operating system just to find a competent editor specifically designed for managing local files, making it especially useful for developers. With Caret, you gain access to syntax highlighting for a wide array of programming languages, as well as a selection of standard themes inspired by Ace, including visual styles that echo popular editors like Eclipse, XCode, and Chrome Dev Tools. Once you've tasted the convenience of executing various edits with just a few keystrokes, reverting back to a single cursor interface can feel nearly impossible. The application not only accommodates multiple cursors and selections but also incorporates familiar Sublime keybindings, such as Ctrl-D for selecting the next occurrence. Instead of spending valuable time memorizing shortcuts, the command palette (Ctrl-Shift-P) lets you begin typing your desired command, prompting Caret to perform a fuzzy search through its menu, effortlessly locating and executing the command for you.
