Inline: Tap to Prompt

REQUIRES SUBSCRIPTION OR YOUR OWN API KEY

Inline requires either an Inline Premium subscription or your own API key (OpenAI, Anthropic, or Groq) to function. Without one of these, the app cannot perform translations or any text transformations. See subscription details at the bottom of this description.

Stop copying text to ChatGPT every time you need to write in another language. Or rewrite a paragraph. Or adjust your tone.

Inline transforms your text right where you're typing. Select, tap, done. No app switching. No copy-pasting. No rewriting the same prompt over and over.

Translation is just the beginning. Inline turns any text instruction into a one-tap action. Rewrite for clarity. Adjust tone for a client. Summarize a long message. Make it sound like a native wrote it. You define the prompt, Inline runs it wherever you type.

HOW IT WORKS

1. Create a custom prompt. "Translate to casual English for X." Or "Rewrite this email to sound more direct." Anything.
2. Set Inline as your default translation tool on iPhone.
3. Select any text in any app, tap Translate, and get your result instantly.
4. Replace the original text with one tap.

BUILT FOR PEOPLE WHO WRITE ACROSS LANGUAGES AND CONTEXTS

Whether you're replying on X, writing an email, or messaging a friend, Inline makes it feel effortless. You set the tone, the context, and the style once. Then you just write.

CUSTOM PROMPTS

Unlike generic translators, Inline uses your prompts. Casual English for Twitter? Professional Portuguese for email? A rewrite that cuts the fluff? Create a prompt for each and switch between them.

TRANSLATION VARIATIONS

Not sure about the first result? Ask for variations and pick the one that sounds right. Compare options before you post.

LEARN AS YOU GO

See how your text was transformed. Notice patterns. Understand what changed and why. Inline helps you get better at writing, not just translating.

YOUR AI. YOUR CHOICE.

Bring your own API key from OpenAI, Anthropic, or Groq — or subscribe to Inline Premium and skip the setup.
