Frequently Asked Questions
Everything you need to know about WritingBot.ai
Yes! All of our core tools are free to use without even creating an account. Free users get generous limits -- 500 words for paraphrasing, 1,200 words for summarization and AI detection, 50 AI tool uses per day, and more. Premium unlocks unlimited access, additional modes, and advanced features like plagiarism checking.
Our paraphraser uses advanced AI to rewrite your text while preserving meaning. You can choose from 10 different modes (Standard, Fluency, Formal, Creative, Concise, Academic, Expand, Shorten, Simple, and Custom). You can also adjust the synonym slider to control how much the vocabulary changes, and freeze specific words you want to keep unchanged.
Yes! WritingBot offers a public REST API that gives you programmatic access to our paraphrasing, grammar checking, summarization, AI detection, translation, and other tools. API access is included with Team plans or available as an add-on for Premium subscribers. Check our API docs for endpoints, rate limits, and code examples.
Our AI Detector analyzes text at the sentence level and provides a probability score for AI vs. human authorship. It is trained to detect content from GPT-4, Claude, Gemini, and other major language models. While no detector is 100% accurate, ours provides sentence-level breakdowns so you can see exactly which parts may be AI-generated.
WritingBot supports 63 languages for translation and our interface is available in multiple languages. The paraphraser, grammar checker, and most other tools work best with English but also support Spanish, French, German, Portuguese, and other major languages.
Absolutely. You can cancel your subscription at any time from your account settings. There are no long-term contracts or cancellation fees. You will continue to have premium access until the end of your current billing period. We also offer a 30-day money-back guarantee if you are not satisfied.
Our grammar checker goes beyond basic spell-checking. It detects and corrects grammar, punctuation, spelling, and style issues in real time. It also provides writing scores for clarity, engagement, tone, and delivery, along with detailed explanations for each suggestion so you can learn as you write. You can choose between American, British, and other English dialects.
WritingBot combines the best features of multiple writing tools into one platform. Unlike Grammarly or QuillBot, we offer paraphrasing, grammar checking, AI detection, summarization, translation, citation generation, PDF tools, and 98+ AI writing generators all in a single place. Our free tier is more generous, and our premium plans are more affordable while offering comparable or better quality.
Yes, we take your privacy seriously. Your text is processed securely and is not stored on our servers after processing is complete. We do not use your content to train AI models or share it with third parties. All connections are encrypted via HTTPS, and we follow industry-standard security practices to protect your data.
