01 / YOUR SPACE

Bring your files together.

Notes, documents, and the projects in between. Give them a local workspace that feels like home.

  • Start with a folder you already have, or create a fresh space.
  • Drag in files and keep different projects in their own workspaces.
  • Keep working in the editor you love.
Your files stay in the folder you choose.

03 / MEET LUMIE

Ask your files.

A second pair of eyes for everything you’re working on. Ask Lumie a question, follow an idea, or make sense of a document.

  • Ask questions in natural language and follow up.
  • Open source references to see where an answer came from.
  • Choose a local model or connect your preferred AI service.
A helpful companion. Always optional.

04 / ROOM TO CHANGE YOUR MIND

Every file has a timeline.

Keep creating. LumeTrace remembers the steps along the way.

One Launch Plan.md file with versions V1 to V4, with earlier and later versions selected for comparison.

Save as usual.

Changes are automatically recorded, even when you use another editor.

See what changed.

Compare supported text versions with line- and word-level Diff.

Find your way back.

Restore an earlier version while keeping the rest of its history.

Feature illustrations use example content. Local history complements a separate backup.

05 / YOUR FILES. YOUR CHOICE.

Local-first
by design.

Your workspace belongs on your storage.
And you decide when AI becomes part of it.

At home on your Mac.

Files, version history, search indexes, and workspace data are stored locally.

Find things without the cloud.

Full-text search works without AI. Optional semantic indexing runs on your Mac.

Choose how you use AI.

Use Ollama or LM Studio locally, or your own cloud provider. When you ask, relevant excerpts and context may be sent to your chosen service.

A LITTLE SPACE. A LOT OF POSSIBILITY.

Make room for your files.

Start your own local-first workspace with LumeTrace.
