Independent add-ons
Tools for learning with more clarity.
Lumen Lab is the public home of our Anki add-ons — careful, offline-first products built to respect your knowledge.
- Offline by default
- Audited code
- Built for FSRS
With structure, context and tools that stay out of the way.
Open catalog
A complete page for every tool we build.
Each product shows what it does, how it works, its current release state and the exact installation path.

Our method
Study software should earn your trust.
An add-on touches a collection you may have built for years. Every decision starts with data safety and ends with evidence.

Audit before redesigning
We reproduce defects against Anki's real engine. Correctness comes before polish.
- 02
Privacy without configuration
No CDN, telemetry or cloud dependency. Your study data remains yours.
- 03
Changes ask for permission
Template migrations are opt-in, compared before applying and protected by backup.

Lumen
A new layer between reading and understanding.
Lumen is being designed to make complex knowledge more navigable, connected and actionable. This site will become its public development journal.
Independent by choice
Smaller products. Greater commitment.
Knowledge tools do not need to capture your attention to be valuable.
We build in public, document limits and prefer one proven capability to ten promises. The catalog is small today because focus is part of the product.
