The top picks

How to choose
Use AI to research (Perplexity), reason over sources (NotebookLM), outline and get feedback (ChatGPT/Claude), and edit (Grammarly) — not to generate work you submit as your own. Most institutions treat undisclosed AI-written submissions as misconduct, and ‘humanizer’ tools that evade detectors are a clear integrity risk. AI also fabricates citations, so verify every source.
If you find yourself juggling a separate subscription for chat, automation, transcription and image generation, one option worth knowing is a single platform that runs them together — osFoundry is one such agentic AI platform that consolidates chat, agents and internal apps in one workspace, with a bring-your-own-key model so you choose the underlying AI.
