Cortex — Support
We’re happy to help.
Cortex is a study workspace that turns your lectures, slides, and PDFs into searchable notes, cited answers, flashcards, and cheat sheets — all stored privately on your device.
Get help
- Email: aidanmcconnon210@gmail.com — the fastest way to reach us. Please include your device model and iOS version.
- Report a bug or request a feature: github.com/PndaMan/cortex/issues.
Common questions
- Do I need an account? No. Cortex works fully on-device with no sign-up.
- Why don’t the AI features respond? AI features use your own API key (e.g. OpenRouter or Google). Add one in Settings to enable chat, cheat sheets, and quiz generation.
- How does sync work? Sync is optional and goes to a server you host yourself (your homelab) over WebDAV. There is no Cortex cloud.
- Where is my data? On your device, and — only if you enable sync — on your own server. See our Privacy Policy.
