Tweetback: AI Copilot for X por Denis

Tweetback is an AI assistant for X that helps you draft replies, create posts, train custom writing styles, and automate parts of your workflow using your own AI provider and API key.

Instead of copying posts into a separate app, Tweetback works directly inside X. It adds reply tools to the timeline, drafting tools to the composer, and automation features for keyword discovery, watchlists, and post generation.

Tweetback is built for creators, founders, operators, marketers, researchers, personal brands, and anyone who wants to stay active on X without sounding generic or robotic.

What Tweetback does
Tweetback helps you work faster on X by letting you:

Generate reply drafts directly under posts
Create replies in different tones, styles, and custom prompts
Train writing personalities from public X profiles
Generate text-only or text-plus-image replies
Create original posts from your own topics
Generate text-only or text-plus-image posts
Choose post language, format, and visual style
Monitor keywords on your feed or search results
Focus on rising posts or reply to any matching post
Run watchlists on specific accounts and reply to recent posts
Use your own AI provider and model instead of being locked into one system

How it works
When you browse X, Tweetback adds reply controls directly to posts. Click a reply style, and the extension generates a draft based on the post content and your current settings. If image replies are enabled, it can also generate an image and insert it into the draft for you.

Tweetback also adds a post drafting tool directly inside the X composer. You can generate original posts from your topics, choose a format, choose a language, and optionally generate matching visuals.

For automation, Tweetback can monitor your feed, search keywords on X, or go through selected accounts from a watchlist. You can use AI-generated replies or your own saved reply text, and decide whether to draft manually or post automatically.
