All AI Tools
26 free AI-powered tools for writing, marketing, coding, SEO, business, and productivity — no signup, no credit card, no limits.
MintAI Tools is a collection of 26 free, browser-based AI tools built for people who need fast results without another subscription. Every tool runs on modern large language models (primarily Llama 3.3 70B via Groq, with automatic failover to Google Gemini), which means you get production-quality output in about two seconds — from a clean interface with no signup wall in front of it.
The tools are grouped into eight categories, each aimed at a specific kind of work. If you're a writer, start with the AI Text Humanizer or the Grammar Fixer. If you're a marketer, the Instagram Caption Generator and YouTube Script Generator tend to be the highest-leverage picks. Developers usually land on the Code Explainer or the Bug Finder.
You don't need to pick a single tool. The ones that work best together tend to cluster: writers use the humanizer, grammar fixer, and paragraph rewriter as a stack. Marketers pair the Instagram caption tool with the headline tester. Coders often chain the code explainer and the bug finder. Below, the tools are sorted by category so you can see what fits how you work.
