Lumen AI

A focused place for your notes, tasks, and ideas — thoughtfully amplified with AI.

Lumen is a minimalist productivity system inspired by GTD, Obsidian, Zettelkasten – with a tasteful amount of AI sprinkled in. It brings your notes, tasks, and ideas into one focused workspace so you can capture fast, stay organised, and do your best work. Being a markdown tool makes it incredibly flexible and adaptable to your way of capturing knowledge and information – and lends itself to a range of really nifty AI features.

• Self-healing Todo List. Lumen's built in AI Todo List self organises based on a structure you define for it e.g. GTD. You can prioritise based on the type of work you feel like doing that day, or context like location or time available.
• Inbox Processing. Get suggestions on how to categorise todos and items in your inbox, or asks for clarifying questions. Review proposed edits to your main Todo List in a diff view.
• Bring text from any app into chat. Paste content into Lumen’s AI chat with the built in Cmd + H keyboard shortcut to ask follow-ups, summarise, or draft emails and responses.
• Capture and summarise meetings. Record audio, get clear notes and action items, and capture key takeaways straight to your Todo List.
• Beautiful Markdown editor. Do your best writing with a gorgeous markdown editor that doesn't get in your way, complete with note hyperlinks and backlinks.
• Custom prompt library. Save your prompts then reuse them in chat and notes. Tell Lumen context about yourself and how you like to draft.

Lumen is the tool I've been dreaming of having in my toolkit for years and I'm glad to get to share it with you. I hope you get the same amount of focus, joy and stress free productivity from it as I do.
