As businesses increasingly rely on AI to manage ideas, organize research, and handle documents, new tools are emerging to make workflows smarter and faster. Google NotebookLM vs ChatGPT Projects are two standout solutions designed to help teams organize knowledge and collaborate more effectively with AI.
Both platforms aim to solve the same problem, making sense of information across multiple documents, but they take very different approaches. This comparison looks at structure, usability, and business impact to help you decide which tool better fits your workflow.
Google NotebookLM vs ChatGPT Projects: What Are These Tools?
NotebookLM (Google)
Google’s NotebookLM is a research-focused notebook that allows you to upload documents and then ask questions based on the information inside them. Think of it as a dedicated AI research assistant that studies your files and delivers precise, source-based answers.
ChatGPT Projects (OpenAI)
ChatGPT Projects is a workspace inside ChatGPT (available to Pro users) where you can store multiple files, take notes, and maintain context over time. It transforms ChatGPT into a memory-enabled work environment for ongoing projects.
While both tools help you understand and work with multiple sources, their strengths differ significantly.
ChatGPT Projects
Best For: Proposal writing, chatbot design, campaign planning
ChatGPT Projects offers a central workspace to organize files, notes, and AI-generated conversations. You can upload PDFs, Word documents, spreadsheets, and images, then ask ChatGPT to extract insights, compare data, or produce structured content.
Business Strengths:
- Convert messy inputs like PDFs, slide decks, and chat transcripts into clean, actionable outputs.
- Maintain full project context over time so you can return to the same task without starting over.
- Draft proposals, product descriptions, chatbot flows, and email sequences.
- Create export-ready formats such as bullet points, scripts, email drafts, and table comparisons.
Callindo Example:
At Callindo, ChatGPT Projects has been used to create marketing scripts for WhatsApp campaigns, organize pitch decks, and support sales teams with templated responses.
Limitations:
- Only available to ChatGPT Pro users.
- No direct integration with Google Docs or Gmail at the moment.
Google NotebookLM
Best For: Research-heavy workflows and internal knowledge hubs
NotebookLM excels in situations where you need to study a large volume of reference material such as product manuals, training documents, or internal policies. Upload your documents, and the AI will answer questions using only the provided sources.
Business Strengths:
- Keeps research strictly focused on the uploaded documents.
- Ideal for onboarding materials, knowledge bases, and compliance training.
- Strong citation capabilities, linking every answer to its exact source location.
- User-friendly for non-technical staff.
Limitations:
- Less suited for creative writing or content generation.
- Minimal formatting for long outputs.
- Lacks the flexibility and adaptability of ChatGPT in generating varied types of content.
