Frequently Asked Questions
How do I add Numexa to my Discord server?
Click the "Add to Discord" button at the top of any page. You'll be redirected to Discord's authorization
page — select your server and approve the required permissions. The bot is instantly active with no setup
needed.
Why is the bot not responding to my commands?
Make sure the bot has permission to read and send messages in the channel you're using. Numexa uses slash
commands — type / to see available commands. If it still doesn't respond, try kicking and
re-inviting the bot.
Is Numexa free?
Yes — the Discord bot and web playground are completely free. The API is currently in open beta with no
authentication required. Rate limits apply to prevent abuse. Paid tiers may be introduced for high-volume API
usage in the future.
What expressions does Numexa support?
Numexa supports everything math.js supports: arithmetic, algebra, calculus (derivatives), linear algebra
(matrices), complex numbers, statistics, unit conversion, and more. See the full
documentation for a complete reference.
Why did I get an unexpected result?
A few common gotchas: trigonometric functions use radians by default (sin(pi/6) not
sin(30)). Exponentiation uses ^ or **. Matrix inverse uses
inv(). Check the docs for exact syntax.
Can I use Numexa's API in my own project?
Yes! The API is open during beta. See the API documentation for endpoints, request
formats, and response schemas. Attribution is appreciated but not required.
How do I report a privacy concern?
Email privacy@numexa.dev directly. We take privacy seriously and will respond within 48 hours.
Is Numexa open source?
The computation engine is built on math.js
(open source, Apache 2.0). The Numexa bot and platform are currently proprietary. We plan to open-source parts
of the codebase in the future.
