Peaque.io

A new way to read — a full ebook reader where the fandom lives right alongside the page. Readers highlight any line to leave a note, and the community celebrates the best ones. Something like a Kindle, Instagram, and Reddit in one app.

The idea

The book and its fandom, in one place.

Readers already live a double life: they read the book in one app, then go to Instagram, Reddit, or a fan wiki to find everyone else’s art, theories, and reactions. Those two worlds never share a screen. Peaque closes that gap — it’s a full ebook reader where the community’s content sits right next to the passage it’s about.

It does everything you expect a reader to do — bookmarks, search, full-screen — and then adds notes: highlight any line and leave a thought, a piece of art, or a theory, just for yourself or for everyone. Other readers can upvote, reply, and share, so a great note spreads and the author’s world keeps growing.

Under it all sits the part we were proudest of: a first-of-its-kind serverless EPUB engine that parses books and renders pages on demand, so any title opens instantly in the browser with nothing to install. We designed and built it end to end on Firebase — the reading engine, the highlight-anchored note system, and the community layer.

Highlights

What makes it work.

Peaque reader — book text with community notes in a side panel
01 — Read

Everything you expect, plus the fandom.

Bookmarks, full-text search, full-screen — the fundamentals of a good reader, tuned so the page is all you see. And as you read, the community’s notes appear right alongside the page, so a scene and the reactions it inspired finally share a screen.

  • Bookmarks, progress, and full-screen reading
  • Full-text search across the whole book
  • Community notes shown alongside the page

02 — Create

Highlight a line, leave a note.

Notes are how the fandom shows up on Peaque. Highlight any text and add a thought, a piece of art, or a theory — kept private for just you, or made public for everyone reading the book. It’s the lightest possible way to turn a solitary read into a shared one.

  • Highlight any passage to attach a note
  • Private to you, or public to the whole community
  • Notes stay anchored to the exact lines they’re about
Peaque popular notes — the community’s best notes on a book
03 — Celebrate

The best notes rise to the top.

As readers add notes, they enrich the author’s world and create new things for other fans to enjoy. Upvote a note to spark joy, reply to start a thread, or share it onward — the community decides what’s worth seeing, and the best of it travels.

  • Upvotes, replies, and shares on every note
  • The strongest notes surface to other readers
  • Public content moderated to community guidelines

04 — Serverless by design

A first-of-its-kind EPUB engine.

An EPUB is really a zipped bundle of HTML, CSS, and assets — normally unpacked by a heavy native app. Peaque does it in the cloud instead: the book is parsed and each page is rendered on demand, so any title opens instantly in the browser with nothing to download. The whole thing runs serverless on Firebase, with no servers to manage.

  • Parses EPUB structure and renders pages on demand
  • Fully serverless on Firebase — nothing to install or run
  • Books open instantly, straight in the browser
Under the hood

Quiet on the surface, careful underneath.

The breakthrough was rendering EPUBs serverlessly — parsing a zipped book and producing pages on demand in the cloud, so the reader is just a browser with nothing to download. The other half was making a note stay attached to the exact words it’s about: anchoring user content to text ranges that survive reflow, font changes, and re-pagination, with a social layer that stays welcoming and moderated as it grows.
