When to choose ChatGPT
OpenAI's ChatGPT remains the most-used AI assistant: GPT-5-class models, voice mode, web browsing, file analysis, image generation, custom GPTs and now agentic task execution in one product.
ChatGPT is still the best default assistant because breadth wins: no rival combines this many capabilities in one place. Writers and coders who value output taste often defect to Claude — try both before subscribing.Read our full ChatGPT review →
When to choose NotebookLM
Google's NotebookLM grounds an AI assistant entirely in documents you upload, with inline citations, study guides, and Audio Overviews that turn sources into a two-host podcast.
NotebookLM is the best free research companion: dump PDFs in, ask questions, trust citations, then listen to the podcast version on your commute. Its grounding discipline is exactly what students need.Read our full NotebookLM review →
