Open Settings
After installing 121 Companion, open iOS Settings. Apple does not let every app jump directly to the Keyboard list, so you may need to keep going manually.

Quill setup
Install Quill on iPhone.
iOS keyboard setup is a little buried. This walkthrough shows the exact path, why Full Access exists, and how to tell when Quill is ready.

Allow Full Access when you want suggestions
Open the 121 Quill entry and turn on Allow Full Access. Local typing still works without it; networked AI suggestions do not.

Why Quill asks for Full Access
Full Access lets a custom iOS keyboard make network requests. Quill needs that only when you ask for an AI suggestion. The suggestion request sends the current sentence context over encrypted transport for inference. Quill does not read your other apps, does not perform ambient keystroke logging, and does not write suggestion context into durable memory after the suggestion returns.
Each suggestion is marked AI - Eleanor before you use it. The 18+ 121 account gate still applies, and Full Access remains optional.
iOS notes
- iOS 17 and iOS 18 use the same general route: Settings > General > Keyboard > Keyboards.
- Apple may open an app-specific Settings page first; continue manually to the keyboard list.
- Secure password fields, some one-time-code fields, and some phone fields may hide third-party keyboards.
- The 121 Companion app includes a status check and a practice text field so you can verify Quill before using it elsewhere.
Troubleshooting
- My keyboard is not showing up.
- Force-quit Settings, reopen Settings > General > Keyboard > Keyboards, and check Add New Keyboard again. Some MDM-managed phones block third-party keyboards.
- Full Access is grayed out.
- Open the 121 Quill keyboard entry from the Keyboards list first. If it is still unavailable, check Screen Time or device-management restrictions.
- Suggestions are not appearing.
- Open 121 Companion, confirm the 18+ account gate, then check that Allow Full Access is on. Secure fields and some phone-number fields can force Apple's keyboard.
- I do not want networked suggestions.
- Leave Full Access off. Quill remains a local keyboard surface, and AI suggestions stay unavailable until you opt in.
