The Quick Verdict: Notion's Edge in AI Recommendations
Notion appeared in 21% of AI assistant recommendations for project management questions, slightly ahead of Smartsheet, which registered 18%. This marginal difference, measured on 2026-06-04 across eight leading AI assistants—Claude, Cohere, Mistral, Perplexity, DeepSeek, ChatGPT, Grok, and Gemini—suggests a slight overall preference for Notion in general project management queries. The data reflects how often these tools were named when users asked common questions about project management software.
This narrow gap points to both tools holding significant, though not equal, standing within the collective knowledge base of these AI models. Notion's slightly higher share could indicate its broader applicability or more frequent discussion across the internet for a wider array of project management scenarios. Smartsheet's strong 18% shows it remains a prominent suggestion, likely for specific, well-defined project needs. The percentages represent mentions across 320 measured questions, providing a snapshot of AI assistant tendencies at that time.
The measurement date is crucial for context. AI models are constantly updated, so these figures reflect a particular moment in their training and knowledge. This head-to-head comparison isn't about one tool being objectively superior, but rather about which tool surfaces more often in AI-generated answers for practical buyer questions. The aggregate data hints at a subtle but measurable difference in how these two popular project management solutions are perceived and recommended by artificial intelligence.
How AI Assistants Choose: Underlying Preferences
AI models do not possess personal preferences or opinions; their recommendations are a direct reflection of patterns in their training data. When a user asks for project management tools, the AI synthesizes information from the vast datasets it was trained on—which include articles, reviews, forums, documentation, and user discussions. The frequency and context in which a tool appears in this training material directly influence how often and for what scenarios the AI assistant will recommend it.
Notion's 21% overall share suggests a broad presence in these training corpora, often associated with a variety of project management needs. Its reputation for flexibility and customization likely contributes to its frequent mention across diverse query types. Smartsheet's 18% indicates it also holds a significant and well-defined position within the training data, often linked to more structured or data-intensive project requirements.
The specific buyer questions, such as those concerning solo freelancers, small teams, strong reporting, agency needs, free options, non-technical users, integrations, and visual boards, all trigger different subsets of the AI's knowledge base. The aggregate percentages show that Notion appears slightly more often across this spectrum of queries, suggesting its perceived versatility resonates broadly within the AI's understanding of project management solutions. Smartsheet, while slightly behind overall, still commands a substantial share, implying its specific strengths are well-recognized by the AI models.
Assistant Divergence: Who Prefers What
The individual AI assistants showed considerable variation in their preferences. Claude, for instance, displayed a strong inclination towards Notion, citing it in 43% of questions compared to Smartsheet's 23%. This significant 20-point difference suggests Notion is particularly prominent in Claude's training data for project management contexts. DeepSeek also leaned heavily into Notion, recommending it 21% of the time, while Smartsheet garnered only 13% of its mentions. Grok, with lower overall mention rates for both, still favored Notion at 10% versus Smartsheet's 5%.
Other assistants exhibited different leanings. Gemini showed the most pronounced preference for Smartsheet, recommending it 8% of the time, while Notion appeared in a mere 3% of its answers. This stark contrast indicates a distinct weighting or representation of these tools within Gemini's knowledge base. ChatGPT also favored Smartsheet, with 18% of its recommendations going to Smartsheet and 13% to Notion. This suggests Smartsheet's more structured approach might be more emphasized in ChatGPT's relevant training data.
Cohere presented a nearly even split, recommending Notion 35% of the time and Smartsheet 38%, indicating both tools hold similar standing in its data. Mistral also showed a close balance, with Notion at 25% and Smartsheet at 23%. Perplexity followed a similar pattern, giving Notion 23% of its mentions and Smartsheet 20%. These near-even distributions imply that for these particular assistants, both Notion and Smartsheet are almost equally salient when project management questions arise, reflecting a balanced presence in their respective training datasets.
What Each Tool is Cited For: A Look at Use Cases
Notion's higher overall mention rate and strong preference from assistants like Claude and DeepSeek point to its common recommendation for flexible, adaptable project management. Buyer questions about solo freelancers, small teams of 10 people, and non-technical teams likely resonate well with Notion's customizable workspace and user-friendly interface. Its ability to serve as a hub for various types of content—documents, wikis, and databases—makes it a versatile suggestion for those seeking a less rigid structure.
The query about highly visual project management software, like kanban boards, also aligns strongly with Notion's capabilities. Its flexible database views allow for easy creation of kanban boards, calendars, and timelines. The need for software that integrates well with common communication platforms is often met by Notion's open API and growing ecosystem of integrations, making it a suitable recommendation for teams prioritizing a connected workflow.
Smartsheet's 18% overall share, and its clear preference by ChatGPT and Gemini, suggests it's frequently recommended for more structured, data-driven project management needs. Questions about strong reporting and analytics for operations managers find a natural fit with Smartsheet's spreadsheet-like interface and solid reporting features. This tool excels at handling complex data, formulas, and automated workflows, making it ideal for organizations that require detailed tracking and performance metrics. The essential features for agencies, which often involve client management, resource allocation, and detailed financial tracking, also align well with Smartsheet's capabilities. Its structured nature can also be advantageous for teams needing clear, consistent processes and strong data integrity.
Choosing for Your Project: A Buyer's Perspective
When selecting a project management tool, consider the nuances revealed by AI assistant recommendations. If your team or project prioritizes flexibility, customization, and a highly visual workspace, Notion might be a more suitable choice. Its strong showing among several AI assistants, particularly Claude and DeepSeek, suggests it's often recommended for solo freelancers, small teams, and non-technical users who value a versatile platform. If your needs include solid kanban boards or a system that can adapt to various content types beyond just tasks, Notion's capabilities align well with these common AI recommendations.
Conversely, if your project demands strong reporting and analytics, a highly structured environment, or a solution that excels at managing complex data, Smartsheet could be the better option. Its significant share of AI mentions, especially from ChatGPT and Gemini, indicates it's frequently cited for operations managers and agencies requiring detailed tracking and advanced features. Smartsheet's spreadsheet-like interface and automation capabilities are often highlighted for teams that need to manage intricate dependencies, financial data, or large-scale projects with precise control.
The best choice depends on your specific operational needs and team culture. The AI assistant data provides a valuable lens, showing which tools are commonly associated with particular use cases. For those seeking a highly adaptable, all-in-one workspace, Notion often surfaces. For organizations requiring powerful data management and structured workflows, Smartsheet receives strong endorsements from other AI models. Evaluate your priorities—flexibility versus structure, visual appeal versus data depth—to make an informed decision.
