Alice vs Checksum

Alice is a native desktop AI assistant that runs inside your operating system and opens with a hotkey. Instead of switching to a browser tab, you summon chat, custom assistants, and automations from macOS, Windows, or Linux while you work in other apps.

The app unifies models from OpenAI, Anthropic, Groq, xAI, and other providers in one interface. You can bring your own API keys to control cost, or subscribe to Alice plans that bundle the app with model tokens for GPT-5, Claude Sonnet, Gemini, and Grok.

Alice goes beyond one-off prompts. You can install ready-made assistants from a library of 50+ personas with 200+ skills, save prompts as keyboard shortcuts, connect MCP servers, and trigger Zapier, Make, or webhook workflows from a single command. Memory and document support lets the assistant keep project context without repeating yourself each session.

Greg Rog and Adam Gospodarczyk built Alice at Techsistence in Warsaw after years of running their own productivity automations. The product targets founders, creators, and teams who want desktop-speed AI that can act on their software stack, not just answer questions.

Generate and maintain end-to-end tests using AI.

Checksum makes it easy for developers and QA professionals to achieve better test coverage for their web apps.

Our software combines real user sessions and machine learning to write E2E tests based on actual user flows and behavior. And if you use Playwright or Cypress, Checksum generates tests using those frameworks, too.
