Hey HN! I'm Armani, a 17-year-old developer. I built these 3 free AI tools in under 2 hours using n8n webhooks and GPT-4o-mini.

The tools: - AI Email Writer: Generate professional emails with 8 types and 6 tones - LinkedIn Post Generator: Create engaging posts with hashtags - AI Code Reviewer: Get instant AI code reviews for 16+ languages

Tech stack: n8n Cloud (webhooks + AI), OpenAI GPT-4o-mini, pure HTML/CSS/JS frontend served via webhook responses.

Everything is free, no login required. Would love feedback on the tools and the technical approach!

Hey HN! I'm Armani, 17 years old, and I built these tools as part of a 24-hour coding challenge on a Raspberry Pi 5.

The tools are completely free, no signup required:

1. AI Email Writer - paste rough ideas, get polished professional emails 2. LinkedIn Post Generator - create engaging LinkedIn content with hooks and hashtags 3. Code Reviewer - paste code in 16+ languages, get detailed senior-level reviews

Tech stack: n8n Cloud for backend (webhook endpoints + AI nodes), server-rendered HTML frontends.

Everything is open source: https://github.com/acunningham-ship-it/free-ai-tools

Would love your feedback! What other AI tools would be useful?
