Set up GhostCalc without the app.
This page talks to your calculator over Bluetooth straight from your browser — the same Wi-Fi settings, AI keys, notes, camera tools and firmware updates the GhostCalc app sends. Built for Android and any desktop Chrome, so you are not waiting on an app store.
This browser cannot use Bluetooth
Web Bluetooth is what lets this page talk to your calculator. It is not available here.
- Android: open this page in Google Chrome (or Edge / Samsung Internet), and turn on Bluetooth and Location.
- Computer: use Bluetooth-enabled Chrome or Edge on Windows, macOS or ChromeOS.
- iPhone / iPad: this browser cannot connect to the calculator. If the phone app cannot connect either, open this address on a supported computer for recovery.
Overview
Everything the GhostCalc app configures, from this page. Settings are written to the calculator the moment you save them — nothing is stored on our servers.
Saved on the calculator
Read live from the calculator's own memory, so you can see what it already has without re-typing anything.
Device diagnostics
Diagnostics appear as the calculator reports them. Older firmware sends fewer fields.
Support details
Wi-Fi
GhostCalc needs a 2.4 GHz network or a phone hotspot to reach the AI. Saving here writes the network straight to the calculator.
AI keys & prompt
Your keys go from this page to the calculator over Bluetooth and are stored in its own memory. They are never sent to GhostCalc servers.
Network privacy
Hide the calculator's identity on the Wi-Fi networks it joins.
Calculator tools
Run the same maintenance and camera actions the app runs.
Setup & connection
Camera
The calculator serves the picture over plain HTTP on your own Wi-Fi, and a secure page is not allowed to load that. Copy the address below and paste it into a new browser tab on the same network.
If the link lands on an error, paste the copied address instead — some browsers force it to https, which the calculator does not speak.
Maintenance
Notes
Send text or a picture to the calculator's notes. Notes are stored on the calculator and read from its NOTES menu.
Picture note
A picture is converted to the calculator's 96 × 63 screen before it is sent. The preview below is exactly what it will look like.
Live chat
Optional. Lets the calculator post to a Discord channel and receive replies. Leave any box blank to skip it.
Bot mode (advanced)
A bot token lets the calculator read replies as well as send. You need it only for two-way chat and the DM router.
Firmware update
The calculator downloads its own update over Wi-Fi. Connect it to Wi-Fi first, keep it powered, and leave this page open until it finishes.
