AI Tools
Free AI tools and utilities: prompt generator, system prompt builder, token counter, LLM model comparison, curated directory of free AI tools and cost calculators for AI APIs.
Working with AI is a new literacy: writing better prompts, counting tokens against model limits, comparing models by price and capability, and estimating what an idea costs at scale before committing to it. These tools exist for the practical side of the AI era — no API keys, no sign-ups.
Token counts are close estimates (the exact tokenizer varies by model); cost math uses published list prices. Good enough for planning — and a habit worth building before the invoice arrives.
