PostX Social Post Assistant

Learn your social voice, plan a content calendar, and draft posts for user-approved publishing to Facebook, Threads, and X (Twitter)

PostX is an AI social-media assistant that lives in your Chrome side panel. It learns your writing voice, plans a 14-day content calendar, and drafts posts for Facebook, Threads, and X (Twitter) — ready for you to confirm and publish. What it does - Learns your style. Point it at your Facebook or X profile and it builds a style profile from your real posts — cadence, emoji density, stance, tone — so drafts sound like you, not a bot. - Plans your calendar. Tell it your goal and posting frequency; it generates a 14-day content plan, with per-day topic hints, formulas, and platforms. - Drafts for each platform. Facebook, Threads, and X each get platform-native drafts — X respects the 280-character limit, Threads gets thread-ready formattin - Diagnoses and reviews. Paste your post metrics and PostX tells you whether a post was diffusion-type or deepening-type, flags red lines, and adjus what worked. Your content stays yours. PostX never autoitly confirmed by you — you click Confirm publish, then PostX places the text into the composer and clicks the platform's Post button. Nothing ships without your action. You bring the model. PostX plugs into yourenAI-compatible API — enter your key in thein-panel settings. Your API key is stored locally in your browser via chrome.storage.local; it is never sent anywhere except your chosen provider. Use the in-panel 中 / EN toggle to switch ts, and UI between Chinese and English at any time. PostX is a third-party tool and is not affiliated with or endorsed by Meta, Instagram, or X. PostX 是一款住在你 Chrome 側邊面板裡的 AI 社群媒體助手。它會學習你的寫作語氣，規劃 14 天的內容行事曆，並為 Facebook、Threads 與 X（Twitter）撰寫貼文草稿——你只要確認後即可發佈。 功能特色： 學習你的風格。 讓它讀取你的 Facebook 或 X 個人檔案，它會從你真實的貼文中建立風格輪廓——發文節奏、emoji 使用密度、立場與語氣——讓草稿聽起來像你本人，而不是機器人。 規劃你的行事曆。 告訴它你的目標與發文頻率，它就會產生一份 14 天的內容計畫，包含每日的主題提示、貼文公式與適用平台。 為各平台撰寫草稿。 Facebook、Threads 與 X 各自取得符合平台原生格式的草稿——X 遵守 280 字元限制，Threads 則採用適合串文的格式。 診斷與檢討。 貼上你的貼文成效數據，PostX 會判斷該貼文屬於「擴散型」還是「深化型」，標記出踩線的內容，並根據有效的做法加以調整。 你的內容永遠屬於你。 未經你確認，PostX 絕不會自動發佈——你按下「確認發佈」後，PostX 才會把文字填入編輯器並點擊平台的發佈按鈕。沒有你的操作，任何內容都不會送出。 自備模型，PostX 可接上任何相容 OpenAI 的 API——在面板內的設定中輸入你的金鑰即可。你的 API 金鑰會透過 chrome.storage.local 儲存在本機瀏覽器中，除了你所選擇的供應商之外，絕不會傳送到任何地方。 使用面板內的 中 / EN 切換鈕，隨時在中文與英文之間切換草稿、提示與介面。 PostX 為第三方工具，與 Meta、Instagram 或 X 均無隸屬關係，亦未獲其背書。
