A Misunderstanding

Miss Brooke had that kind of beauty which seems to be thrown into relief by poor dress. Her hand and wrist were so finely formed that she could wear sleeves not less bare of style than those in which the Blessed Virgin appeared to Italian painters; and her profile seemed to gain the more dignity from her plain garments, which gave her the impressiveness of a fine quotation from the Bible — or from one of our elder poets — in a paragraph of today's newspaper.

17She was usually spoken of as being remarkably clever, but with the addition that her sister Celia had more common sense.

Note · p. 142#dorothea
The dress as moral signal — Eliot is already telling us what Dorothea will refuse from the world.

I. A book is private.
II. A library should be too.

"Your reading life is a long conversation with yourself. It does not belong on a server."

IIThe shelf, the desk, and the lamp

Six things Lexis does
that other readers will not.

01

Local‑first, by design

No servers, no accounts, no telemetry. Your library, highlights, and notes live in browser storage or — on desktop — a folder you own. The whole app is one HTML file you could read by candlelight.

0 bytes leave your machine, ever.
02

Every format you have

PDF, EPUB, MOBI, AZW/AZW3, FB2, CBZ, TXT, DOCX, HTML, Markdown. Plus .lex bundles and .lexis backups for sharing annotations between devices without a cloud.

03

Highlights that mean something

Four colours, each renamable. Tag them, write notes, and re‑find them across the entire library. Annotations key by content hash, so renaming files never breaks a marginalium.

Project Gutenberg, on the shelf

Browse 70,000 free classics from Gutendex without leaving the app. Subjects auto‑map to a clean academic taxonomy. Open Eliot, Tolstoy, or Austen in two clicks.

Read aloud, beautifully

Web Speech TTS with adjustable rate and pitch, voice list, and live word‑highlighting that follows the reader. Walk the dog while Middlemarch finishes its paragraph.

IIIThe Library

A bookshelf that
remembers everything you've underlined.

Drop a file, paste a URL, or open a Gutenberg classic. Lexis fingerprints the content (SHA‑256), so the same book on two devices shares one set of marginalia — synced through a portable .lexis backup, no account required.

On the Mathematical Properties of Attention‑Free Sequence Models

Hessel, P. · Mori, A. · Vossen, K.
cs.LGstat.MLcited 47×

We characterise a family of sequence models in which attention is replaced by a linear recurrence with learned gating, and prove a separation result on long‑range dependencies that depends only on the spectral radius of the recurrence matrix…
