WhereToPost: Reddit Rules & Drafts

Check subreddit promotion rules and create one editable Reddit comment draft with your own AI provider.

WhereToPost is a browser side panel for Reddit users who want to read the rules before they post. It gives you two tools you trigger yourself: a saved community-rule reader and editable Reddit comment drafts. The rule reader works without an AI provider. After you click a button, the extension sends only the exact subreddit name to WhereToPost and displays the saved result: paired English originals and Chinese translations, the third-party source, the time the rules were read, and a link to Reddit's current rules page.

Comment drafts use the AI provider and model you choose: OpenAI, Anthropic, Google Gemini, DeepSeek, OpenRouter, or any HTTPS OpenAI-compatible endpoint. Your API key stays in extension-local browser storage on your device. After you click Generate on a Reddit post, the extension reads only the current post title and body, or on a permalink to one comment, only that exact comment. It sends the material and an optional take directly to your selected provider in one request, and returns three editable English drafts: helpful, concise, and conversational. The Simplified Chinese interface adds a matching Chinese reference for each draft. Drafts are saved locally for the exact post or comment and tone, at most 20 drafts for 30 days. Nothing is posted, voted, messaged, or submitted automatically. A draft is inserted into the Reddit reply box only after you click Insert, and the extension never clicks Reddit's submit button. A content script runs only on supported Reddit hosts to detect an open
