Everyone keeps asking which AI to use for college. ChatGPT is the obvious answer, but $20/month adds up fast. So I spent a week using only the free tiers of DeepSeek, Gemini, and Claude – for actual student tasks. Here’s what genuinely surprised me. Task 1: Writing a college essay introduction DeepSeek – Got the job done but felt formulaic. Fine for a first draft, needed noticeable editing. Gemini – Decent but played it safe. Correct, not impressive. Claude – Noticeably better. Real hook, built naturally into the argument. Minimal editing needed. Winner: Claude – and it wasn’t close. Task 2: Researching current information DeepSeek – Gave me outdated info confidently. That’s worse than saying it doesn’t know. Gemini – Clear winner. Real‑time web access, cited sources, structured breakdown. Google’s ecosystem makes this a completely different tool for research. Claude – Honest about its knowledge cutoff (respectable) but not helpful when you need current data. Winner: Gemini – not even a contest for anything requiring recent sources. Task 3: Solving a calculus problem step‑by‑step DeepSeek – Genuinely impressive. Every step explained clearly, with reasoning behind each. Felt like a patient math tutor. Gemini – Got it right, explanation was solid but slightly less detailed. Claude – Also correct, and explained it in a way that actually made it click for me. Winner: DeepSeek – for pure math it’s remarkable, and the free tier has no usage limits. Task 4: Summarising 3,000 words of lecture notes DeepSeek – Compressed the notes but didn’t really synthesise them. Same structure, same order, just shorter. Gemini – Better. Pulled out key concepts and organised them logically. Claude – Best by far. Didn’t just compress – it reorganised, identified core arguments, and produced something that genuinely felt like study notes, not just a summary. Winner: Claude again. Task 5: Explaining quantum computing to a beginner DeepSeek – Technically accurate but dense. Not great for true beginners. Gemini – Good analogies, kept it accessible. Linked to helpful resources – a nice touch. Claude – Outstanding. Built the concept layer by layer using a real‑world analogy. Felt like a great teacher explaining it, not a Wikipedia article. Winner: Claude. Task 6: Generating practice exam questions DeepSeek – Solid factual questions, good variety. Functional, nothing special. Gemini – More exam‑realistic questions, better for humanities subjects. Claude – Generated the questions, then offered to quiz me interactively – one question at a time, waiting for my answer and giving feedback. That changed everything for exam prep. Winner: Claude. Final scorecard But here’s the thing – picking one is the wrong approach. The smartest free student setup in 2026 Claude – writing, summarising, understanding concepts, exam prep Gemini – anything requiring current information, research, or Google Docs integration DeepSeek – math, logic, coding (completely unlimited free access – use it as your personal math tutor) Total cost: $0 A quick note on DeepSeek DeepSeek is a Chinese company, and data is stored on servers subject to Chinese law. For math problems and general questions, it’s perfectly fine. I wouldn’t share anything personal or sensitive with it. What’s your AI stack for college right now? Have you tried all three side‑by‑side? I’d love to hear if others are seeing the same patterns. I wrote a full breakdown of all six tasks (with examples and prompts) here: DeepSeek vs Gemini vs Claude: I Tested All Three as a Student for a Week.
