Simple tools.
Seriously useful.Free Wi-Fi scanner, PDF reader & PDF organizer for Windows and Android

We build features that are 100% useful, not 100 features of which you use 1%. Every llemonai product is simple to learn, powerful where it matters, and focused on solving one problem well.

Wi-Fi Scanner

For network engineers, IT teams and anyone troubleshooting Wi-Fi. Scan nearby networks live, decode beacon frames, track signal strength (RSSI) over time, compare 2.4 GHz and 5 GHz channel usage, and export a field-ready PDF report. Free for Windows and Android.

llemonAI Reader

For advocates, lawyers, online tutors, lecturers, students and corporate trainers. Annotate PDFs, combine PDF and Word files into one, collect key passages on a whiteboard, and show only the PDF page on a projector or video call (Windows). Free for Windows and Android.

PDF Organizer

For anyone whose PDF is too large to email or upload. Reduce PDF size by shrinking only the photos and scans that need it, while text pages stay sharp. Reorder and rotate pages, combine PDF, Word and text files, and add or remove page numbers. Free for Windows and Android.

Insurance Vault Coming soon

For families keeping track of their insurance. A private web app in development that brings cover from bank accounts and cards, policies from IRDAI-registered insurers and employer group policies together in one place.
Why separate shelves

Different problems don't read the same way

The Scanner lives or dies on technical depth — protocol internals, signal timing, chipset quirks. The Reader lives or dies on getting out of your way — mark up a document, find the sentence you need, hand back one clean file. The Organizer lives or dies on precision — shrink the photo that's too big, leave the page of text alone. The Vault lives or dies on trust — clear numbers, calm paperwork, a claim sheet your family can actually use. Forcing them onto one palette would undersell all of them, so each keeps the look it has inside the product. The llemonai wordmark is the only thing they share.
