Slopster: Translate Posts & Draft AI Replies on Reddit, X & Facebook

Translate for free, no sign-up. Draft replies in your own voice with your own AI key, then edit and post them yourself.

Found a thread you want to join, but it's in a language you don't read? Or you know what you want to say, but writing it in another language takes forever, and AI tools make it sound like a chatbot? Slopster sits next to Reddit, X, and Facebook and helps you read a thread, then reply in your own words. READ ANY THREAD • Click Translate under a post or comment and the translation appears right below it. • Or turn on automatic translation, and posts translate as you scroll. • Translation is free and works right away. No sign-up, no key. REPLY WITHOUT THE STRUGGLE • Click Draft reply, jot down the point you want to make, and get a draft in the language of the thread. • Next to it you get the same draft in your language, so you know exactly what you are about to say, plus a few notes on what to double-check. • Drafts follow your profile: who you are, how you talk, and words you never use. An optional style setting keeps them from sounding like an assistant. • Writing a new post instead? Open the site's post form and Slopster drafts the post, with a title on Reddit. YOU HAVE THE LAST WORD • Slopster puts the draft into the reply box you opened. It never sends or posts anything: you read it, change what you like, and send it yourself. • It tells you when a reply may not fit the thread, and on X it counts your 280 characters. • Drafts are asked to stick to what your profile says about you, not to make up stories. AI can still get things wrong, so read every draft before you send it. WHAT YOU NEED • To translate: nothing. • To draft: your own key from OpenAI, DeepSeek, Google Gemini, or Anthropic Claude. You pay that company directly for what you use. Slopster itself is free. YOUR DATA • Your key stays on your computer. • Text is sent only to the translation or AI service you chose, and only when you ask for it or turn on automatic translation. • Slopster has no server, no account, and no tracking. Also: optional ad hiding on each site, your choice of translation color, and Slopster itself in English, Spanish, or Chinese. Works on the desktop versions of reddit.com, x.com, and facebook.com. Please don't use it for spam or mass posting, and follow each community's rules.
