AI Image Generator Workflow: Claude + Gemini via n8n Form

Turn form submissions into AI-generated images—automatically sent to the requester

This n8n workflow takes an image request from an n8n Form, enhances it with Anthropic Claude (Sonnet 4.6), generates the image with Google Gemini (PaLM), then emails the result via Gmail and logs everything to an n8n Data Table.

What this workflow does

• Collects input via n8n Form Trigger: captures the requester’s email, image description, and preferred style.
• Normalizes fields for consistent values (email, description, style) before processing.
• Prompt enhancement with Anthropic Claude (Sonnet 4.6): combines the user description and style into a single, vivid, style-aware image-generation prompt.
• Image generation with Google Gemini (PaLM): sends the enhanced prompt to Gemini and outputs the generated image as binary data.
• Emails the generated image to the requester using Gmail, including the style and the prompt used.
• Logs request details (description, style, prompt, timestamp) to an n8n Data Table (e.g., image_gen_log) for tracking and reuse.

Use cases

• SaaS support or onboarding: collect user image ideas and deliver a generated concept quickly via email.
• Marketing operations: turn campaign briefs submitted through an n8n Form into style-consistent image outputs.
• Creative teams: prototype variations by requesting new styles and keeping a prompt history in a Data Table.

Technical details

• Nodes / tools mentioned in the workflow: set, gmail, data table, sticky note, form trigger, and an n8n LangChain agent node (n8nn8n-nodes-langchainagent).
• Credentials required:
  • Anthropic credential for Claude Sonnet 4.6 (prompt enhancement).
  • Google Gemini (PaLM) API credential with the selected image model available.
  • Gmail OAuth2 credential with permission to send emails.
• Data Table: create/select image_gen_log (or update the workflow to your table name).
