Claude Sonnet is the strongest fit for extracting action items and decisions from meeting notes. You can paste your notes directly into the chat and prompt it to return a structured list of action items (with owners and deadlines if present) alongside a separate list of decisions made. Its instruction-following and summarization capabilities make it reliable for this kind of structured extraction task. ChatGPT is a solid alternative if you already have a Plus subscription and prefer OpenAI's interface, while Gemini Flash works well if you want a free option with fast turnaround on shorter notes, and NotebookLM is worth considering if you want to upload multiple meeting documents and query across them over time.
