Question: Is there a platform that enables me to run AI models for data summarization, cleaning, and classification directly in Google Sheets?

If you want a platform to run AI models for summarizing, cleaning and classifying data right in Google Sheets, Neptyne is a great choice. The system marries data science tools that are already widely available with Google Sheets so you can import data from many sources and perform more advanced processing like summarization, refinement and classification with AI models. It also has visualization and automation abilities, so it's good for a lot of practical uses.

Another contender is Numerous.ai, an AI plugin that brings ChatGPT abilities to Google Sheets and Excel. It's relatively easy to set up and uses a syntax that's similar to =AI. It's good for summarizing and categorizing data, but also for brainstorming and content generation. With several pricing tiers, including a personal option for individuals, it's adaptable to different needs.

If you want a more powerful productivity tool, check out GPT Workspace. This tool brings ChatGPT and Gemini to Google Workspace, letting you automate processes involving Google Sheets, Google Docs, Google Slides, Gmail and Google Drive. It can summarize data, generate content and run custom prompts on all kinds of files, so it's a powerful option for productivity and data processing.
