7 Must-Have Website Chatbots for Test Prep

ChatGPT, built on OpenAI’s advanced language model, has become the go‑to chatbot for students seeking real‑time help across a wide range of subjects. The platform offers free access with optional paid plans, providing students with instant, conversational explanations and the ability to generate custom study materials. With its broad knowledge base, ChatGPT can answer conceptual questions, solve math problems, and offer essay outlines. However, while powerful, ChatGPT lacks built‑in tools for structured test‑prep workflows, such as scheduled practice sessions or progress tracking. Its free tier is generous but limited by token usage, and the premium plan ($20/month) provides priority access but does not include specialized tutor functionalities. For educators looking for a general-purpose AI assistant, ChatGPT’s versatility and ease of use make it a solid choice, especially for small tutoring practices that need a low‑barrier entry point.

Khanmigo, the AI companion from Khan Academy, is tailored specifically for STEM and test‑prep contexts. By integrating Khan Academy’s rich content library, Khanmigo offers interactive tutoring that adapts to each student’s pace and comprehension level. Students can ask for step‑by‑step explanations, receive practice problems, and track their progress through the platform’s built‑in analytics. Khanmigo’s subscription model ($20/month) grants access to the full suite of personalized learning tools, including real‑time feedback and mastery-based checkpoints. While it excels in delivering subject‑specific guidance, Khanmigo is limited to the Khan Academy ecosystem, meaning it may not seamlessly integrate with external learning management systems or other third‑party content. For educators who rely heavily on Khan Academy resources and want a tightly integrated AI tutor, Khanmigo provides a compelling, focused solution.

QuizCat AI transforms student notes into interactive quizzes, flashcards, and audio podcasts, making it a unique tool for test‑prep. Starting at $9.99/month, the platform offers a freemium model that allows educators to upload lecture notes, textbook excerpts, or custom study material, which QuizCat then converts into engaging learning assets. The AI’s ability to generate diverse question formats—multiple choice, fill‑in‑the‑blank, and short answer—helps students practice recall and application. While QuizCat excels in content transformation, it does not provide real‑time conversational assistance or deep knowledge retrieval; instead, its focus is on creating spaced‑repetition study aids. For tutors who need to quickly generate high‑quality practice materials, QuizCat AI is an efficient solution, especially for small to medium‑size educational providers.

Socratic, a free app from Google, is designed to help students solve problems by simply taking a photo of the question. The app provides step‑by‑step guidance across subjects such as math, science, literature, and history. By leveraging image recognition and AI, Socratic can interpret handwritten or printed problems and walk students through solutions. While its focus on visual problem solving makes it valuable for high‑school learners, Socratic lacks a robust knowledge base or conversational AI; instead, it offers static, image‑driven instructions. The platform’s strengths lie in its accessibility and zero cost, but it does not support personalized learning paths or progress tracking. For students who need quick visual assistance, Socratic is a handy, no‑cost tool.

Otter.ai specializes in transcription and note‑taking, offering users AI‑powered verbatim transcriptions of lectures, meetings, and study sessions. With a starting plan of $16.99/month, Otter provides searchable transcripts, keyword extraction, and speaker identification, making it a useful companion for students who want to review and organize study material. While Otter excels at capturing spoken content, it does not offer real‑time tutoring or interactive question answering. Its primary use case is for students who prefer to capture audio lectures and later review them, rather than for those seeking immediate AI guidance. Otter’s strengths include high transcription accuracy and robust search features, but it lacks a dedicated test‑prep framework.

Eesel.ai offers a suite of AI tools aimed at enhancing customer support, internal communication, and content creation. Its product lineup includes an AI chatbot that can be embedded on a website, an AI copilot for drafting replies, an AI email writer, and an internal chat system for instant answers within teams. Eesel.ai boasts integrations with popular platforms such as Zendesk, Confluence, Freshdesk, Google Docs, Slack, and Shopify, allowing businesses to streamline workflows across multiple channels. While Eesel.ai’s tools are powerful for automating routine tasks, the platform does not specifically target test‑prep or educational use cases. It is best suited for organizations looking to improve internal knowledge sharing or customer engagement rather than for tutors.
