Humbot
What it is
Humbot is a web-based AI study and writing assistant with tools for revising text, checking writing, and working with study materials. Its features include an AI humanizer, article rewriter, grammar checker, plagiarism checker, AI detector, summarizer, ChatPDF, translator, citation generator, math solver, and quiz generator. ChatPDF can summarize PDFs and answer questions about them; the summarizer accepts videos, webpages, and long documents. The translator supports more than 100 languages, while the API humanizer supports more than 50. Its citation tool supports more than 40 styles and can create citations from titles, content, URLs, DOIs, and ISBNs. Humbot says its detector checks content against services including Originality.ai, ZeroGPT, Turnitin, and GPTZero. The service identifies students, content creators, freelancers, ESL learners, business professionals, and educators as intended users. It claims ISO 27001, SOC 2, and GDPR compliance and says documents are not stored, shared, or used to train its AI. A free API trial allows up to 250 words; API use is suspended at the word limit until additional credits are purchased.
