The short version

I’m Lucas. I’m a developer who got tired of forgetting everything he reads.

So I started building tools to fix that. True Recall is the biggest one — an Obsidian plugin that turns your notes into a spaced repetition system powered by AI and FSRS v6. No more switching between Anki and your notes. No more orphaned flashcards with zero context.

But the tools are just a side effect. The real obsession is learning itself — how it works, why it breaks, and how to make it faster without losing accuracy.

Why learning?

I have ADHD. For years, my “study sessions” were two hours of highlighting followed by zero retention. I thought I was stupid. Turns out, I was just using methods designed for brains that don’t work like mine.

So I went deep: cognitive science, neuroscience, spaced repetition algorithms, the Feynman technique, Zettelkasten, active recall research.

What I found: most “productivity” advice is garbage. Most note-taking systems are digital hoarding. Most people who “study for 6 hours” actually learn for about 20 minutes.

The single most valuable skill in 2026 isn’t coding, marketing, or AI prompting. It’s learning how to learn — fast, accurately, and in a way that sticks.

What I build

  • True Recall — Spaced repetition inside Obsidian. AI-generated flashcards from your notes. FSRS v6 scheduling. No separate app needed.
  • Episteme — An experimental AI learning system I built (and rebuilt three times) to test how AI can assist with knowledge acquisition.
  • Obsidian Claude Sidebar — Run Claude Code directly inside Obsidian.
  • This site — Where I write about what actually works for learning, and what’s just noise.

What I write about

  • How to learn with AI without becoming dependent on it
  • Spaced repetition, active recall, and the science behind memory
  • Building your own learning tools (even if you’re not a developer)
  • Why most PKM systems fail and what to do instead
  • ADHD-specific learning strategies that aren’t just “try harder”

The stack

TypeScript, React, Astro, Node.js, Python. 600+ atomic notes in Obsidian. Claude Code as a daily driver. A custom FSRS-based spaced repetition engine. And way too many unfinished side projects.
