SwissBoard is a system-wide AI keyboard for iOS. Tap an action chip to polish grammar, translate, rewrite as a punchy post, or sprinkle emojis — directly inside Mail, Messages, X, Slack, Notes, or any text field. Bring your own key. SwissBoard talks directly to the AI provider you configure, using an API key you control. There is no SwissBoard server in the loop. Privacy by design. Your draft is sent directly from your device to the provider you configured. SwissBoard never collects, stores, or accesses what you write. Tracked-change diffs. Every suggestion shows up as an inline diff so you can see exactly what changed before you accept, rewrite, or retry. Custom action chips. Add your own prompt templates. Reorder them. Disable the ones you don't need. Built-in actions: • Polish grammar & clarity • Rewrite as a punchy post • Translate (auto-detect → target language) • Emojify Requires Allow Full Access to call your AI provider. No tracking.
