Focus on the conversation

Understand the context.
Then shape your reply.

01

Read in your preferred language

Translate messages and quotations separately. Choose reading and reply languages independently, with an optional source-language override.

02

Start with your own perspective

Add a thought or question to get up to three suggestions. Edit, check the character count, and copy a reply yourself.

03

Make the panel fit your flow

Move, resize, and switch between one or two columns. The panel remembers its position. Enable auto translation in settings when you want it.

04

See your participation locally

View comments, replies, quotes and totals by date and website. Export, correct or add missed records. Statistics stay in this browser.

Start with one post

Three steps into the conversation.

  1. 01

    Open the assistant

    Click the icon beside an X post. Review the selected text and loaded earlier messages.

  2. 02

    Translate and add context

    Read in a familiar language and add your own perspective, question or missing details.

  3. 03

    Edit, then copy

    Choose a useful suggestion, make it sound like you, and copy it to X yourself.

Your language. Your model.

Connect a familiar provider.
Keep your preferences.

Use presets for DeepSeek, OpenAI or OpenRouter, or configure a custom HTTPS OpenAI-compatible provider. Bring your own API key; API usage is billed by your provider.

Presets simplify configuration. Compatibility depends on the provider and model. The interface supports English and Simplified Chinese.

  • Direct to your chosen provider

    Selected content and notes go directly to your configured AI provider when you request assistance. With auto translation enabled, opening or refreshing a conversation can also trigger a translation.

  • Keys in trusted extension contexts

    Keys are kept for the browser session by default, with an option to remember them locally. Page content scripts never receive them.

  • Statistics you control

    Disable, export, correct or clear local statistics. They are not sent to the developer or AI provider. Generating and copying do not count as publishing.

Ready for your next conversation

Understanding and expression.
One window.

A few things before you begin

Do I need a paid account?

There is no shared AI account. Configure your own compatible provider’s API key. Translations, reply generation and connection tests may incur provider API charges.

Will it post on my behalf?

No. Replies are generated only when you click. You edit, copy and post them yourself. Auto translation is off by default and can be enabled in settings.

Which platforms and content are supported?

Currently, desktop Chrome and X text conversations. Images, videos, linked pages and unloaded messages are not analyzed. Statistics cover activity observed in this browser; uncertain categories can be corrected manually.
