A few things to know

What do I need to get started?

Install Xboost in Chrome or Firefox, open X, and configure a product profile. To use AI drafting, connect your own running Codex App Server in Settings with its WebSocket address and capability token.

Does Xboost publish replies for me?

No. You can review and edit a draft, copy it, or ask Xboost to fill the X reply composer. You check the account and click Reply yourself. Xboost doesn't automatically like, follow, or switch X accounts.

Can I use it without AI?

Yes. Profile targeting, searching, and local scoring work without AI drafting. Enable AI when you want eligible posts prepared as drafts.

Will I get 100 drafts every day?

Discovery has a configurable target, not a guaranteed result. Progress depends on relevant posts available on X, your filters, freshness settings, and Codex capacity. You open searches and browse; Xboost works with loaded posts.

Is my content sent outside my browser?

With AI enabled, post text, author handles, URLs, and your selected product context go to your configured Codex server and OpenAI. Searches go to X. Scoring and profile storage stay local.

Does it have a dark theme?

Yes. Arctic Daylight and Ocean Signal are available in the extension. Try the theme button at the top of this page to see the same palette here.
