PostCraft AI

Overview

PostCraft AI is an AI-powered content creation agent that transforms topic briefs into publication-ready social media posts with custom-generated images. It combines intelligent image generation, visual selection, and multi-platform copywriting to automate the entire post assembly workflow—from concept to LinkedIn and X submission—saving content teams hours of manual design and editing work.

How It Works

1. Claude Sonnet analyzes the content topic — Examines the provided topic or caption draft and generates a detailed, optimized image generation prompt specifying visual scene, style, color palette, mood, and composition.

2. FLUX.1 generates the primary image — Produces a high-quality image from the prompt using FLUX.1 [dev] FP8, delivering professional-grade visuals optimized for social sharing.

3. Imagen creates an alternative image — Generates a second image variant using Imagen 4 Fast to enable A/B comparison and selection.

4. Claude Haiku evaluates and selects the best image — Compares both images on relevance, visual quality, and brand alignment, then automatically selects the superior option for publication.

5. Claude Sonnet writes platform-specific captions — Crafts a LinkedIn caption (600–900 characters) and an X post (under 280 characters) tailored to each platform's audience and format requirements.

6. Google Drive saves the selected image — Uploads the chosen image to your content assets folder for organized asset management and future reference.

7. LinkedIn post submitted for approval — Routes the LinkedIn post with image to designated approvers for human review, feedback, and final authorization before publishing.

8. X post submitted for approval — Routes the X post with image to approvers for review and approval, maintaining quality control across all social channels.
