| Description | PromptHub is a collaborative prompt engineering platform where teams and individuals can host, share, and discover prompts publicly or privately. It offers Git-based versioning, AI-assisted prompt generation and enhancement, a testing playground with side-by-side output comparison and evaluations, prompt chaining, and pipelines with guardrails. Prompts can be deployed across environments via branches, an API, shareable Forms, and a Zapier integration. | Dia is an AI-native browser from The Browser Company (creators of Arc) that integrates with tools like Slack, Notion, Calendar, Gmail, and GitHub. It generates morning briefs, pulls together information spread across tabs and apps, answers context-aware questions about on-screen content, and helps users prepare for meetings. Aimed at knowledge workers, it is currently available only on macOS. |
