2 Slash vs Checksum

2Slash is a Chrome extension that runs an AI writing assistant on any webpage without typing prompts yourself. You pick actions from a built-in prompt library, and the extension generates text, images, or speech in context where you are already working.

Browser chat tools expect you to craft prompts for every task. 2Slash preloads expert-written prompts for text, image, and video workflows so you select an action instead of engineering wording. The library includes 50+ free prompts on the free tier and 100+ expert prompts on paid plans.

Free accounts on 2slash.ai include 3,000 words per month, 5 generated images, and 1,000 text-to-speech words across models like GPT-4o, Gemini 1.5 Pro, Claude 3.5, and Llama 3 with no OpenAI API key required. Premium at $14 per month raises limits to 20,000 words, 25 images, and 10,000 TTS words plus unlimited prompt requests.

2Slash targets marketers, support teams, and operators who want generative AI inside Gmail, docs, and social sites without switching tabs. Enterprise and prompt-on-demand services are listed separately on 2slash.ai for teams that need custom prompt packs.

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.
