Xext - Themes & Tools for X (Twitter)

Customize X's layout and themes, save posts with notes, and draft with on-device AI. Free tools; optional lifetime Pro.

Custom themes, a cleaner timeline, and on-device AI for X (Twitter). Xext's local UI and productivity tools are free forever. Pro is a one-time $9.9 lifetime license for saved posts and accounts, timeline filters, advanced X themes, and on-device AI. Xext does not require X login or call the X API. THEMES FOR X Use free Paper and Midnight, or seven Pro palettes including Porcelain, Sakura, Lagoon, and Dusk. Themes cover supported reading pages: timelines, search, profiles, post threads, and photo viewers. Utility pages keep X's native appearance. A CLEANER TIMELINE Collapse navigation, hide the right sidebar, center or widen your feed, adjust density, and hide Grok or Premium shortcuts. Focus breaks help you pause. Pro filters hide labeled promoted posts and reposts, filter keywords and accounts, and highlight the best visible reply using engagement shown on the page. ON-DEVICE AI WRITING Two Pro buttons in X's composer polish your draft or write a new post from a topic and tone. A separate writing workbench is also available. Chrome's built-in model runs on your device; compatible Chrome and hardware are required, and a model download may be needed. No cloud AI fallback. Review and edit every result; Xext never publishes for you. LOCAL LIBRARY Save and reopen searches for free. Pro adds saved posts, account writing samples, notes, tags, and collections. PRIVACY AND PRO Settings, saved content, notes, and writing instructions stay in this browser. JSON export/import excludes license and installation identity. X content is not sent to Xext's servers or third-party AI services. There is no background profile crawling or automated X account activity. Optional Pro costs $9.90 once. Creem handles checkout; activate the emailed license key in Xext Settings. License operations contact the Xext license service. No subscription, free trial, X OAuth, or required Xext account. Xext is independent and is not affiliated with, endorsed by, or sponsored by X Corp. Third-party names belong to their owners.
