I used DeepSeek, Gemini and Claude every day for a week as a student. They're all free. But they're very different.
A week-long test reveals Claude dominates writing and study tasks, while Gemini excels at research and DeepSeek shines in math.
A comprehensive week-long test of free AI assistants for student work reveals clear strengths and weaknesses across three major models. Anthropic's Claude emerged as the overall winner, taking 4 out of 6 tasks including essay writing, note summarization, concept explanation, and exam preparation. Claude's standout feature was its ability to reorganize and synthesize 3,000-word lecture notes into genuine study materials, plus interactive exam quizzing that transformed test preparation.
Google's Gemini dominated research tasks with real-time web access and source citations, making it essential for current information. DeepSeek's model proved exceptional for calculus problems with detailed step-by-step explanations and no usage limits. The optimal free setup combines Claude for writing and studying, Gemini for research, and DeepSeek for math tutoring - demonstrating that no single model excels at everything.
- Claude won 4/6 tasks including essay writing (minimal editing needed) and note summarization (reorganized 3,000 words into study notes)
- Gemini dominated research with real-time web access and source citations - essential for current information
- DeepSeek excelled at calculus with detailed step-by-step explanations and no usage limits on its free tier
Why It Matters
