Make it easy to help you
Reporting a bug
- The page it happened on — copy the page's address.
- What you were doing, what you expected, and what actually happened.
- Your device and browser (e.g. iPhone, Safari) — most issues are device-specific.
- A screenshot helps more than a paragraph.
Requesting a tool
- What the tool would do, in one or two sentences.
- When you'd reach for it — a real moment, like “before my chem lab report is due”.
- The most-requested ideas get built first.
Support the project
The Codex is free and always will be. If a tool saved your evening before a deadline, you can support the indie developer behind it:
Frequently asked questions
How fast will I hear back?
Every message is read personally, and most get a reply within a couple of days. Reports about broken calculations or pages that don't load jump the queue.
Can I suggest a new tool?
Yes — pick “Tool request” in the form, describe what the tool would do, and say when you'd reach for it. The most-requested ideas get built first.
Where can I get help with a specific tool?
Email is fastest. Tell us which page you were on and what you were trying to do — see the bug-report tips on this page for what helps most.
