Turn 10 years of Readwise highlights into an AI persona

Readwise is the most underrated dataset most knowledge workers own. Five, ten, fifteen thousand highlights — every line you cared enough to save from every book and article you've read in the last decade. It's the closest record of your intellectual taste in existence. And almost nobody is using it for anything but the daily review email.

The numbers

  • 5,000–20,000 highlights for a typical heavy Readwise user over 3–5 years.
  • ~95% never re-surfaced. Daily review hits a handful per day; the rest sit in storage.
  • 2–5 MB of Markdown for a full export. Tiny by any standard.
  • $8–10/mo Readwise subscription — but the highlights themselves are yours, regardless of subscription state.
  • 0 native integrations with ChatGPT, Claude, or Gemini that would let those models actually read your library.

The export, in 3 steps

  • Open Readwise in the browser, go to Settings → Export.
  • Pick Markdown as the format. (CSV works too, but Markdown preserves the book/article hierarchy.)
  • Download the file. It's a single Markdown document with every highlight, every source, every note you've ever added.

Why pasting it into ChatGPT doesn't work

The intuitive thing is to drop your Readwise file straight into a chat and ask the model to "use this as context." Two problems:

  • Token limits. A serious Readwise library is far too big to fit in any model's context window. You'd be paying to truncate yourself.
  • Relevance. Even if it fit, the model has no idea which 30 highlights matter for your current question. You'd get vague, average-y answers.

What works is a distillation layer: pre-process the whole library once, find the patterns (authors you return to, ideas you've highlighted multiple times, themes that cross books), and produce a short persona file. That persona fits in any prompt and actually reflects your taste.

Short answer

Export your Readwise library as Markdown (Settings → Export). Drop it into a memory vault that distills your highlights into a compact persona summary — recurring authors, repeated ideas, the themes that cross sources. Paste that persona at the top of any AI conversation and you'll get answers that actually sound like a model that's read what you've read.

The portable answer

Konshus has a Readwise importer on Founding and above. You drop the Markdown export in once and we run distillation across the whole library — finding the authors you keep coming back to, the ideas you've highlighted in different books, the themes that show up across years. The output is a persona file short enough to paste into ChatGPT, Claude, or anything else.
