why it exists
ai chats were not built for real work.
If you use AI every day, the same problems keep showing up. Prompts get lost. Context gets retyped. Threads get too long. Output needs cleanup. Project rules live everywhere except where you need them. lum9a turns the AI chat box into a workspace.
cleaner handoffs
Restart long threads with structure instead of dragging old context forever.
local by default
No lum9a account, server, database, analytics, or AI API calls.

faq
straight answers.
Does lum9a use an AI API?
No. lum9a does not call OpenAI, Anthropic, Google, or any AI API. It works locally in your browser.
Does lum9a send my prompts to a server?
No. Saved prompts, snips, profiles, and settings are stored locally in your browser.
Does the context meter count exact tokens?
No. It gives a local estimate based on conversation length. It is meant as a practical signal, not an exact tokenizer.
Does lum9a work on every website?
Version one focuses on ChatGPT, Claude, and Gemini. Some generic browser features may work elsewhere, but the core experience is built for AI chat tools.
Can I delete my data?
Yes. You can delete saved prompts, snips, profiles, or reset all local extension data.
