Claude is the strongest alternative for writing and long documents. Gemini is best if you live inside Google Workspace. Perplexity replaces ChatGPT entirely for research where citations matter. NotebookLM is better when the answer must come only from your own sources. For coding specifically, Cursor and Claude beat a general chatbot.
