Guides

What the evidence says about learning, and how to make an AI run it for you. Each guide stands alone and cites its sources.

Start here

• How to learn with AI, properly

  Four rules separate learning with AI from being answered by it. Two randomized trials in 2025 show what each side costs.

• The best way to learn in 2026

  The two techniques the evidence ranks highest, what people do instead, and a daily routine that follows the ranking.

Speed and work

• How to learn fast and remember what you learned

  Speed is measured a week later. The method with the least re-learning is the fastest.

• Upskilling in 2026: how to learn a technical field while working

  Thirty to forty-five minutes a day, one concept in prerequisite order, measured by what you can explain.

The tools

• What an AI tutor must do, and why a chat window is not one

  Six requirements from two trials with opposite results, and a table against a human tutor.

• Spaced repetition with AI: cards made from what you were just taught

  Cards after understanding, two to four per concept, into Anki, with the review history as the measure.

• The Feynman technique with AI: explain it back, the next day

  An explain-back graded against the lesson, the day after you read it, with a prompt you can paste.

The harness

• The method: how The Learning Harness teaches

  The rules the harness runs, in the order a learner meets them, and the evidence each one leans on.

• Frequently asked questions

  Availability, requirements, cost, Anki, your data, and what happens when you fail a test.
