Post Forge Sensei (formerly Post Forge)
Post Forge Sensei is a social media content planner that drafts a full month of platform-native posts for Instagram, X, and LinkedIn from your website URL. You paste a link, review an auto-built brand kit covering voice, audience, and colors, then get themed weekly slots with captions, hashtags, and image briefs tailored to each network. Nothing publishes until you approve every post in the Studio review desk.
Where most AI schedulers cross-post the same caption everywhere, Post Forge writes separate copy per platform and routes finished posts through your own Buffer account. Generation runs on your OpenRouter API key with zero markup, so a typical month of copy costs about $0.70 plus per-image fees starting around $0.06. That pay-per-use model suits teams who already manage API keys and want cost transparency over bundled credits.
Solo founders and small marketing teams use it to batch a month of on-brand social content in one sitting. Agencies reviewing client posts get an approval workflow before anything hits Buffer's queue. The invited beta starts in a lobby with a sample month you can approve to test the full loop before your account unlocks generation.
