Slopster
Translate posts in place and draft replies and new posts in your persona's voice with your own AI key. Slopster only fills the box; you review and send.
People who read and take part in conversations on Reddit, X, and Facebook across languages.

Overview
- A Chrome Manifest V3 side-panel extension for translating and writing on Reddit, X, and Facebook.
- Drafts replies and new posts in the voice of a persona you define, with a copy in your own language and review notes.
- Never sends or publishes anything: it only fills the box you opened, and you review and send.
Common Uses
- Follow and join discussions in languages you do not read.
- Reply to comments in your own voice and tone without sounding like AI.
- Draft a new post for a subreddit, your X timeline, or a Facebook group.
Requirements
- Google Chrome with side-panel support.
- An API key for OpenAI, DeepSeek, Google Gemini, or Anthropic Claude to draft text; translation works without a key through free Google Translate.
