About this extension
Draft posts and replies from your product brief, then review them before you share.
DefPromo keeps your projects, writing variations and local activity history in a browser sidebar. Bring the page's context into a reply, edit the draft, and copy it or fill a supported compose box. You choose whether to publish.
FROM BRIEF TO EDITABLE DRAFT
• Keep separate projects with their URL, audience, features and tone.
• Generate post or comment variations, with optional links and titles where supported.
• Review and edit the page context for a reply.
• Reopen saved variations, copy a draft, or fill a supported form.
• Get generated subreddit, hashtag and search ideas to investigate.
• Keep a local record of form fills. Add likes, comments and shares manually to compare your own records.
• Export and import your projects, content, settings and history as JSON.
SETUP AND COSTS — FIREFOX 1.4.9
The currently published Firefox version uses your own OpenAI API key. Automatic product-page extraction also requires a configured scraper service: ScrapingBee, ScraperAPI or Browserless. Enter those keys in Settings. Provider accounts and usage charges are separate from the extension; installing DefPromo does not include free AI or scraping usage.
CONTROL AND PRIVACY
Projects, settings and history are stored in your browser. Generation sends the relevant project brief and reply context to OpenAI; automatic product analysis sends the product URL to your selected scraper service. Exported settings can contain API keys: keep backup files private.
DefPromo fills forms; it does not schedule posts or automatically publish them. Its activity counts are not verified posts, reach, follower growth or platform-wide analytics. Check the draft, the destination and each community's rules before sharing. Site changes can affect form filling; copying remains available.
VERSION NOTE
OpenProfile site-file reading, OpenConnection access through myna, and NicheDB forum suggestions were added in 1.5.0. They are not included in the Firefox 1.4.9 package currently offered here. The screenshots show the published Firefox version using an example project and sample drafts.
