What makes EchoFlow different
Built specifically for students
Drop your Registration PDF
Drag your registration timetable PDF — subjects and slot codes detected in seconds.
Instant Slot Mapping
Every slot (A, B, C, P1, P42...) is automatically mapped to your registered subject.
Beautiful & Customizable
Auto-assigned colour palettes distinguish theory from labs. Change any colour, rename subjects.
Official Timetable Structure
Uses the exact grid structure for Batch 1 and Batch 2 — looks just like the official timetable.
Export Anywhere
Export as PNG or PDF. Print-ready output preserves your colours, layout, and hidden columns.
100% Private & Free
No login. No backend. No data ever leaves your browser. Everything saved in LocalStorage.
How it works
From PDF to timetable in 4 steps
Choose Your Batch
Select Batch 1 or Batch 2 — the official grid is loaded automatically.
Drop Registration PDF
Upload your registration timetable PDF. Text is extracted instantly, no OCR needed.
Review & Customize
Verify auto-detected subjects. Edit names, change colours, cancel specific classes.

Your data never leaves your device
EchoFlow is 100% client-side. Your registration PDF is parsed directly in your browser using PDF.js — never uploaded to any server. All your customizations (colours, names, hidden slots) are saved in your browser's LocalStorage.
