Hi, I'm David πŸ‘‹

πŸ“š Founder of Lex | πŸ›οΈ Empire-Builders | ⚑ Book/tool/media maximalist

Building the new Library of Alexandria: books, audiobooks, citations, summaries, speed reading, history media, and every weird tool that makes reading feel alive again.

JavaScript TypeScript Next.js React Supabase Tauri Capacitor AI YouTube

Start Here

  • πŸ“š Lex - read, upload, track, and discuss books; 6M+ free books, 30,000+ audiobooks, iOS, Android, web, and desktop.
  • ⚑ BlitzReads - speed reading for classics and EPUBs; sentence mode, word mode, 300-750 WPM.
  • 🧾 Lexipedia - Wikipedia, but book citations open the cited page in context through Google Books + Lex.
  • πŸŽ™οΈ LexVox - long-form voice generation and audiobook tooling for books, essays, and creators.
  • πŸ›οΈ Empire-Builders - history documentaries, podcasts, and book clubs about the rise and fall of imperial civilizations.
  • 🧠 lexicon - early experiments in AI-readable book summaries and knowledge compression.

Current Projects

Lex Core

  • πŸ“– Lex Reader - the main reading platform: public-domain library, uploads, shelves, progress tracking, highlights, notes, social discovery, and author pages.
  • 🎧 Audiobooks - 30k+ LibriVox titles, synced playback, chapter mapping, full-screen player, mini-player, CarPlay-style audio metadata, and native mobile audio work.
  • πŸ€– Lex AI - reading companion, inline edits, summaries, book intelligence, recommendations, and context-aware chat over a user's library.
  • 🌍 Translations - AI-assisted translations for classic works, public-domain editions, and Lex-original releases.
  • πŸ“„ PDF to EPUB - scanned books and PDFs converted into reflowable reading experiences.
  • πŸ—ΊοΈ Literary Map - bookstores, libraries, literary events, and discovery around real-world reading culture.
  • πŸ§‘β€πŸ’» Creator Tools - publisher onboarding, 90% author royalties, uploads, premium editions, and book production workflows.

Reading Experiments

  • ⚑ BlitzReads - "read at the speed of thought"; rapid serial visual presentation plus sentence-context speed reading.
  • πŸ† BookTierList - ranking books visually, because taste is more fun when it starts arguments.
  • πŸ‡ΊπŸ‡Έ POTUSTierList - presidents, tiers, history nerdery, and exactly the kind of discourse the internet deserves.
  • πŸ“š Comprehensive Summaries - Blinkist-style Lex editions for major works, generated from actual book text and published as readable books.
  • πŸ”Ž X-Ray / Book Intelligence - characters, chapters, themes, and reading context without fake quote theater.

Knowledge & Citations

  • 🧾 Lexipedia - a live Wikipedia mirror that makes book citations useful instead of dead footnotes.
  • πŸ”– Citation Resolver - detects book refs, parses ISBN/title/author/page, and opens the source in Google Books or Lex.
  • 🧠 Book Graph - editions, translations, audiobooks, PDFs, IA scans, Gutenberg records, Open Library, Google Books, Apple Books, Hardcover, and more.
  • πŸͺͺ Author/Bio Pipelines - catalog enrichment, author pages, summaries, covers, and metadata cleanup at scale.

Voice, Audio & Media

  • πŸŽ™οΈ LexVox - voice generation for long-form content, designed around books instead of 15-second clips.
  • πŸ—£οΈ Audiobook Generation - Qwen3-TTS experiments, voice design, voice cloning, chapter extraction, batch generation, and S3 delivery.
  • 🎼 Ambient Reading Audio - music manifests, background tracks, reading modes, and audio engine work.
  • 🎬 Empire-Builders - produced, edited, and presented history content; Roman roads, empires, biographies, presidents, and long-form educational videos.

History & Publishing

  • πŸ›οΈ Empire-Builders Podcast - 24+ episodes on imperial civilizations, late Rome, Carolingians, Holy Roman Empire, and the deep roots of state formation.
  • πŸ“œ Empire-Builders Book Club - biographies, classics, and primary sources for people who think bookstores should come with battle maps.
  • ✍️ Little Corporal's Dispatch - history, econ, geopolitics, tech, books, movies, and occasional Napoleonposting.
  • πŸ—οΈ Library of Alexandria Project - the larger mission: make the world's serious books easier to find, read, cite, hear, summarize, translate, and share.

What I'm Building Toward

  • πŸ“š A real alternative to Amazon for books - better economics for authors, better UX for readers, no lock-in.
  • 🌐 A universal reading layer - EPUBs, PDFs, scans, audiobooks, citations, translations, summaries, and social context in one place.
  • 🧠 AI that helps people read more deeply - not fake homework summaries, but tools for comprehension, memory, and discovery.
  • πŸ›οΈ History media with receipts - videos, podcasts, and essays connected back to sources and books.
  • πŸ› οΈ Many small tools - because a good side project is just a future feature trying to escape.

Tech I Reach For

  • βš›οΈ Frontend - Next.js, React, Tailwind, CSS modules, mobile-first web UI.
  • 🧱 Backend - Supabase, Postgres, Vercel, Typesense, S3/CloudFront, Stripe.
  • πŸ“± Native - Capacitor for iOS/Android, Tauri for desktop, native plugins when the webview taps out.
  • πŸ€– AI - OpenAI, Gemini, Anthropic, AI SDK, structured generation, metadata extraction, voice generation.
  • 🧹 Pipelines - Node, Python, workers, cron, batch imports, EPUB/PDF processing, catalog enrichment.

Legacy / Side Quests

  • πŸ§ͺ lexicon - early public repo and experiments around structured summaries.
  • 🧒 POTUSTierList - presidents ranked with the seriousness this unserious format demands.
  • πŸ“• BookTierList - book taste as a shareable artifact.
  • ⚑ BlitzReads - speed reading, shipped standalone.
  • πŸ›οΈ Empire-Builders - media, podcasting, historical research, editing, scripting, production.
  • 🧬 Web3 experiments - Farcaster/onchain identity dabbling before returning to books and civilization.

What I'm Doing

  • Shipping Lex every day.
  • Turning public-domain books into something normal people actually want to use.
  • Building tools for readers, authors, publishers, autodidacts, and history freaks.
  • Making AI do useful grunt work: citations, metadata, summaries, translations, narration, cleanup.
  • Trying to make "read more books" feel less like homework and more like the internet got good again.

Connect


Recognition / Receipts

  • Built Lex into a cross-platform reader with millions of books, tens of thousands of audiobooks, uploads, shelves, AI, native apps, and publisher tooling.
  • Created BlitzReads, a free speed-reading site for classics and EPUB uploads.
  • Created Lexipedia, a citation-first Wikipedia reading experiment.
  • Produced and hosted Empire-Builders, history content about empires, biographies, and the long arc of civilization.
  • Worked on The Armchair Historian as editor, writer, researcher, and proofreader.

Philosophy

"The empires of the future are the empires of the mind."

β€” Winston Churchill, Harvard University, 1943

Random facts:

  • Thinks every book app is secretly a civilization simulator.
  • Has too many side projects and considers this a feature.
  • Believes citations should take you to the page, not a footnote graveyard.
  • Wants authors to keep more money.
  • Will probably make a tier list about it.
