Litedoc v2.0 — The Major Release

The biggest update yet. Faster. Smarter. Tougher.

Core Engine Upgrades

Document Layout Analysis (DLA) Engine

Replaced blind linear reading with a recursive XY-Cut algorithm. Litedoc now geometrically maps every page, isolating headers, sidebars, and main text blocks for perfect reconstruction.

DLA Engine DLA Engine 2 DLA Engine 3

Asymmetrical Multi-Column Routing

Massive improvements for academic papers. The engine now detects microscopic gutters and natively processes columns top-to-bottom, eliminating horizontal text interleaving.

Vector-Based Table Reconstruction

Enhanced addons.js intersection matrix logic now captures table structures as clean Markdown grids, bypassing the need for OCR on structured data.

Heavy-Duty Memory Management

Massive stability boost for large (200+ page) documents. The new Batch Queuing system processes files in 10-page chunks, forcefully clearing VRAM between cycles to prevent browser crashes.

Performance & Reliability

Language Auto-Detect (OSD Router)

The OCR engine now runs a lightweight 400×400px OSD pre-pass to detect script (Arabic, Latin, etc.) before initializing the heavy-duty language workers.

OSD Router

Intelligent Image Triage

Automatically detects native text vs. image-based PDFs, routing to the optimal path to save processing time and battery.

Image Triage

Mobile & Desktop Optimization

Aggressive performance tuning including a 150 DPI cap for mobile OCR and worker respawning every 5–10 pages to defeat iOS/Android thermal throttling.

Crash Recovery & Telemetry

If a file fails, the UI now flags it with an error badge and provides a one-click litedoc-crash-log.txt for easy bug reporting.

Developer & UX / UI Improvements

Mobile UI

We've completely overhauled the UI for mobile devices, ensuring a seamless experience on all screen sizes.

Mobile UI

Modular Architecture

Completely decoupled the codebase. The project is now structured for easy community contributions, with a new Python build script that compiles the distribution-ready index.html.

Manual Hallucination Fallback

Added an "Unformat" button inside the editor. If the parser ever makes a mistake, one click instantly strips markdown/table formatting, returning the selection to plain text.

Queue Control

New "Skip" functionality allows users to force-abort long-running files without locking the application thread.

Minor Improvements & Maintenance

Area What Changed
General Polish Series of under-the-hood refinements and stability patches across the interface
Micro-Optimizations Dozens of small adjustments to rendering speed, UI responsiveness, and memory footprint
Refined Error Handling Improved edge-case handling for malformed PDF object streams to prevent silent failures

A Note on Performance

Litedoc runs entirely in your browser. While v2.0 handles large files significantly better, please be mindful that OCR is computationally expensive. For massive 200+ page documents, stick to native text PDFs whenever possible—if you force OCR on a 200-page image-only PDF in a mobile browser, you're going to hit hardware limits (because physics).

🔭 Looking Ahead

A massive thank you to everyone who supported this project via Ko-fi.

My focus moving forward is purely on stability, broader PDF format support, and extreme optimization.

🤝 Want to Help?

The codebase is now fully modular. If you're a dev, check the repo and send a PR; it's easier than ever to contribute. I'm taking a well-deserved break, but if you have questions, reach out via email or X.
