AI System Prompt Generator for LLMs with Unli.dev

This n8n workflow generates comprehensive system prompts for LLMs from simple human inputs using Unli.dev's chat completions. It structures outputs with persona, mission, rules, output format, and designer notes, ensuring consistency across AI applications.

Benefits include fixing prompt inconsistency, improving LLM outcomes, and providing a competitive edge through standardized AI behavior—like an always-on style guide. Teams save time on wording debates and focus on shipping features.

The workflow triggers on HTTP POST to the 'systempromptgenerator' webhook path, processes input via Set/Prepare nodes, calls Unli.dev for single-turn generation, extracts the prompt, and responds via webhook. Ideal for prompt engineers, product managers, developers, and AI ops automating testing/deployments.

Perfect for systematizing prompt design, locking AI behaviors pre-launch, and integrating into CI pipelines. Security note: Replace with your Unli.dev API key.
