# There Is An AI Tool > Plain-English AI tools directory + explainer site. We review 190+ AI tools, publish 165+ jargon-free articles, and ship four free in-house tools (humanizer, text detector, prompt improver, cost calculator) — no sign-up, no upsell. Updated weekly. Audience: non-technical readers who want to understand and use AI without the hype. Last updated: June 28, 2026. ## Free in-house tools - [AI Humanizer](https://thereisanaitool.com/ai-humanizer): Rewrites AI-generated text to sound human. Removes the six common AI tells (tricolons, hedging openers, corporate filler, transition crutches, robotic rhythm, "not just X, but Y" constructions) while preserving meaning exactly. Free, no sign-up, up to 500 words per request. - [AI Text Detector](https://thereisanaitool.com/ai-text-detector): Estimates how likely a piece of text was AI-written. Three independent signals — AI tell phrases, sentence rhythm, and an LLM judgement — shown separately with a plain-English explanation. Honest about accuracy limits (~50–65% per published research). - [AI Prompt Improver & Generator](https://thereisanaitool.com/prompt-improver): Paste a draft prompt and get a stronger version with an itemised breakdown of what changed. Or generate a full prompt from a one-line idea. Tuned for ChatGPT, Claude, Gemini, and Midjourney. - [AI Cost Calculator](https://thereisanaitool.com/ai-cost-calculator): Compares per-request and at-scale costs across 12 frontier AI models (GPT-5, Claude Opus 4.8, Gemini 3.5 Pro/Flash, DeepSeek V3, Grok 4, Llama 3.3, Mistral Large 2, and more).
