n8nChat

n8nChat is a Chrome extension that embeds AI assistance into the n8n workflow editor. It generates, edits, debugs, and optimizes n8n workflows from natural language descriptions. The tool accesses users’ existing workflows, custom nodes, and editor elements like sticky notes to produce context-aware outputs. It integrates with AI models including OpenAI’s GPT-5 series, Anthropic’s Claude, Google’s Gemini, and xAI’s Grok via API keys provided by users.

Core functionality centers on a sidebar chat interface within n8n. Users input prompts describing desired automations, such as connecting APIs or building AI agents. The extension parses these to create node structures, set parameters, and connect data flows. It supports full workflow generation, partial edits, error identification with suggested fixes, and performance tweaks like loop optimizations. Technical implementation uses JavaScript to interface with n8n’s DOM and APIs, ensuring outputs align with n8n’s JSON-based workflow format.

Competitors include Relay.app, which offers AI-driven task automation but requires separate workflow exports to n8n, and Gumloop, focused on visual AI flows without native n8n embedding. n8nChat provides tighter integration for n8n users, enabling in-editor modifications. General pricing includes a free tier for basic usage and paid options for extended API access, comparable to Gumloop’s per-operation model but lower for n8n-specific tasks.

Users report benefits in rapid prototyping, with workflows built in seconds versus manual hours. It handles AI agent chains effectively, incorporating tools like vector stores or external APIs. A key feature is model-agnostic support, allowing backend switches for varied reasoning needs. Drawbacks involve occasional inaccuracies in complex credential setups, requiring manual verification, and dependency on prompt clarity for optimal results. Recent updates added GPT-5 compatibility and sticky note parsing, improving contextual accuracy.

External feedback from Product Hunt and Reddit highlights 40,000+ users since April 2025 launch, with praise for debugging aids and model variety. X posts note seamless Grok API integration for creative prompts. Limitations appear in niche custom nodes, where generation may need adjustments. The tool processes prompts via selected LLMs, outputting editable n8n JSON.

Test n8nChat on a single-node workflow first, verify outputs against manual builds, and iterate prompts for precision to build reliability.
