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!
