graphing
Private graphing calculator with no account
Graph Lab plots in your tab without a UtilBloom login—expressions stay local unless you copy a share hash—ideal when you want a Desmos-like grapher with less account sprawl.

The problem
Tutors and students often want a full grapher without storing identities in another edtech account. Upload-based calculators also conflict with privacy habits used for PDF homework.
How private plotting works here
Open /graph, type expressions, and work entirely in the tab. Local storage may remember the last document on that browser; share hashes are opt-in when you copy a link. Open a private multi-expression demo.
When Desmos accounts still make sense
Keep Desmos when you need Classroom rosters, saved activity history, or district licensing. Graph Lab is the private Desmos-like scratchpad beside /guides/private-browser-tools.
FAQ
Do I need a UtilBloom account?
No account is required to start plotting in Graph Lab.
Is local storage private on shared PCs?
Anyone with the same browser profile may see the last saved doc—clear site data or use a fresh profile on lab machines.
Are share links public?
Anyone with the URL can reopen the encoded document—treat hashes like shared files.
