FoxSpark is a browser extension that helps you generate draft posts for X (formerly Twitter) in your personal writing style. It works by analyzing publicly available profile information and tweets to build a voice profile, then uses AI to generate drafts that match your tone.
chrome.storage.Our backend uses third-party AI model providers (such as OpenAI and Google) to generate drafts. Tweet content may be sent to these providers as part of the generation process. These providers are bound by their own privacy policies and data processing agreements.
We do not sell, rent, or share your data with third parties for advertising, analytics, or any purpose unrelated to the extension's core functionality.
Voice profiles and ingested tweet data are stored on our servers to enable draft generation across sessions. You may request deletion of your data at any time by contacting us.
You may request access to, correction of, or deletion of any data associated with your X/Twitter username by contacting us at the email below.
