Built for practice.
Lumen started because the dental-board prep market was broken. Question banks were either ten years old or sourced from recalled content — sometimes both. The good ones cost a month’s rent and still left candidates guessing which topic was actually costing them marks.
So we built our own. Our current publishing workflow uses AI-assisted drafting, checks against published sources, and a separate AI review. We do not claim licensed-human sign-off for every question in the bank.
Today: 9 boards, 23,000+ approved items, one promise we won’t make — that you’ll pass. That part is on you.
Current question workflow
How a question is built.
STAGE 01
Drafted
Our current workflow uses AI-assisted drafting against published competency blueprints and source guidance.
STAGE 02
Checked
Automated checks screen question format, source links, answer keys, and possible duplicates.
STAGE 03
AI reviewed
A separate AI reviewer assesses the draft and its sources. This is not licensed-human clinical sign-off.
STAGE 04
Student ready
Item enters the bank, gets blueprint-weighted into your next diagnostic or mock — and your weak-topic feed adapts.
Behind Lumen
Independent.
Source-informed.
Lumen is an independent study platform. Our current workflow combines published sources, automated validation, and AI review. These checks can miss errors. Use the cited references and flag unclear questions for review.
