ReadingFix – Repair broken reading mode on websites

Make Substack and similar sites readable again with one-click reading mode repair

Problem

Substack obfuscates text with spacerless spans, breaking Chrome's reading mode and showing users an unspaced mess. For those who rely on reading mode to filter noise and focus, this deliberate breakage ruins the experience.

Solution

A browser extension or userscript that detects spans splitting words, reconstructs proper spacing, and outputs clean text to reading mode or a standalone view. Works with major reading tools like Chrome's built-in and Readwise Reader.

Users

Heavy readers, researchers, knowledge workers subscribed to many Substacks.

MVP

Chrome and Firefox extension; auto-detect split text and insert spaces; toggle button to fix/unfix; optional enhanced reading view.

Revenue

Free basic + paid pro (more site rules, cloud sync, batch export), one-time purchase or yearly subscription.

Why now

Platforms like Substack are fighting reading tools, but demand for clean reading persists. Indie devs can react fast while giants won't bother.
