About

lum9a command center is a local-first AI productivity extension for people who use ChatGPT, Claude, and Gemini every day.

It adds a clean command palette directly inside your AI workspace so you can save prompts, reuse context, clean AI output, create handoff templates, estimate conversation length, and organize your AI work by project — all without accounts, servers, databases, or AI API calls.

Open the command center with a shortcut or by typing “/” inside a supported AI chat.

What lum9a command center does:

Search saved prompts
Save and reuse your best AI prompts without digging through old chats.

Insert reusable context
Create snips for project rules, brand voice, coding instructions, writing style, teacher policies, or any context you use often.

Save selected text
Highlight useful text from an AI response or webpage and save it as a prompt or snip.

Clean AI output
Remove markdown clutter, extra spacing, em dashes, excessive formatting, and messy AI copy before pasting somewhere else.

Create handoff templates
Build a structured new-chat handoff when a long AI conversation starts losing focus.

Estimate context usage
Get a local estimate of how long your AI thread is so you know when to summarize or start fresh.

Switch project profiles
Organize prompts and snips by project, workflow, or client.

Privacy-first by design:

No account
No server
No database
No cloud sync
No analytics
No AI API calls
No data sent to lum9a

Your saved prompts, snips, profiles, and settings are stored locally in your browser using chrome.storage.local.

lum9a command center is built for AI power users, founders, developers, teachers, students, writers, creators, and anyone who wants ChatGPT, Claude, and Gemini to feel more organized, focused, and useful.

Use lum9a command center as your local AI workflow layer: prompt manager, context injector, AI text cleaner, context meter, handoff builder, and project command menu in one simple Chrome extension.
