Atua
What is Atua?
Atua puts AI inside any Mac app through a global hotkey bar, custom commands, and context pulled from selected text, screenshots, clipboard, voice, or screen OCR. You build reusable prompts once, assign keyboard shortcuts, and run them from Mail, Slack, Xcode, or any other window without copying content into a separate chat tab.
Browser-based assistants make you leave your workflow; Atua stays in the app you are already using and can chain actions through built-in Mac tools plus MCP servers for GitHub, Postgres, Slack, and more. The trade-off is platform lock-in: it is macOS only, and you bring your own API keys from OpenAI, Anthropic, Groq, and other providers rather than getting bundled credits.
Developers, writers, and creators who live in keyboard shortcuts use Atua to polish emails, summarize diffs, post MCP actions, and dictate voice paste locally. A one-time $29 license includes unlimited commands, system tool access, and lifetime updates with no subscription.
Nexus
What is Nexus?
Nexus adds an AI navigator on top of Mesh, the personal CRM that organizes contacts from email, calendar, and social accounts. You ask questions about your network and Nexus pulls relationship context to suggest who to reach out to, what to say, and when to follow up. It is built for people who manage dozens of professional relationships and need faster answers than scrolling through notes.
Generic chatbots do not know who you met last quarter or which client changed jobs. Nexus reads the contact history Mesh already stores, so prompts like gift ideas or reconnection reasons come back tied to real people in your roster. That network memory is the gap most AI assistants skip, and it is why Nexus sits inside Mesh rather than working as a standalone chat window.
Sales professionals, freelancers, and small business owners use Nexus to find the right contact, draft outreach, and plan introductions or events without rebuilding context from scratch. If you already track relationships in Mesh, Nexus turns that database into a queryable guide for day-to-day productivity.
