# AI Reply Generator for X (Twitter) in Your Voice Canonical page: https://depost.ai/features/x-ai-replies Open a post on X and Depost AI drafts a reply that fits the thread: short, specific, in the tone you set. Add your take, pick an angle, edit, and send it yourself. Nothing is posted for you. Last updated: 2026-09-17. **AI replies for X:** Depost AI is an AI reply generator for X (Twitter) that drafts short replies in your voice from the post, the thread above it, and your take. You edit and send each reply yourself. ## Why it matters A reply on X sits under a post that already has readers, which is more than a new post from a small account gets. It has to land in a line or two, in the register of the thread, and it has to be yours: the feed can smell a template. Depost AI drafts from the post and the conversation above it, with your angle in it, and leaves the sending to you. - **27×** a like: the weight of a reply in X’s open-sourced ranking model, 13.5 against 0.5 (source: X open-source algorithm, 2023). - **150×** a like when the author answers your reply, the largest positive signal in that model (source: X open-source algorithm, 2023). - **8%** more engagement on X for accounts that reply to comments, across about 2 million posts (source: Buffer, 2025). ## How it works 1. **Open the post.** Depost AI reads the post and the replies above yours, so the draft answers the actual turn in the conversation. 2. **Pick the angle, add your take.** A comment type, a tone, and a line of what you think. Ask for several drafts and each takes a different angle. 3. **Edit and send it yourself.** The draft lands in the reply box. Cut it, change it, or use it as is, then send. Depost AI never posts on X for you. ## What's in it - **Short by design.** Replies on X are drafted under their own rules: a line or two that answers the post, with no LinkedIn paragraph carried over. - **Thread-aware replies.** Replying inside a thread is a turn in a conversation. The draft reads the thread, including your earlier replies, and answers what was last said. - **Your take, in your words.** Add your perspective and the draft is built around it, or from it alone. The reply with an opinion in it is the one that gets quoted. - **Angles you can pick.** Ask for up to five drafts and each takes a different angle, labeled: Experience, Counterpoint, Question. Pick the one you would have written. - **Tones that adapt.** Fifteen tones from Professional to Humorous. Adaptive mode keeps yours but matches the thread, so a joke gets a joke back. - **Topics to skip.** Set the topics you engage on and the ones you leave alone. Outside them, Depost AI writes nothing. ## Questions people ask ### Does it post replies on X for me? No. Depost AI drafts into the reply box and stops. You edit and send. There is no auto-reply, no bot, and nothing that touches your account without you. ### Will the replies sound like me? They are drafted from your name and headline, the tone and comment type you set, and the take you add. The more of your own view you put in, the more the reply reads as yours, and every draft is yours to edit before you send it. ### Is it the same as the free AI tweet generator? The free tool writes a new post from a topic. This drafts replies to posts you are reading, in a thread it has read, with your styles, tones, and take applied. Different job. ### How long are the replies? You set the length as a range of words, and replies on X default to short. Whatever the draft, you see it in the box before it goes anywhere. ### Can I keep the same voice across LinkedIn and X? Your tone, comment types, and saved styles are yours everywhere; the drafting rules change per platform so a reply on X reads like X. The topics you engage on can be set per platform. ### Does it work in other languages? Turn on Use Post Language and the reply comes back in the language of the post. ### What about Threads and Facebook? Replies on Threads follow the same short-form rules as X. Comments on Facebook are drafted as full comments, like LinkedIn. Each has its own page. ## Related - [AI replies for Threads](https://depost.ai/features/threads-ai-replies): AI replies for Threads, drafted in your voice from the post, the conversation, and your take.
