And spoiler: while each has its strengths, one stands out when it comes to real-time collaboration.
Best AI Models of 2025
With numerous AI assistant options emerging in 2025, how do you determine the best fit for your team's needs? At Shadow, we realized that meetings represent the ideal test environment to evaluate these powerful AI tools. Why meetings? Because the biggest challenge in meetings isn’t collaboration itself—it’s memory. Accurately capturing and recalling crucial insights, decisions, and innovative ideas discussed is exactly where an AI assistant's true value becomes evident.
In this comprehensive analysis, we compare three leading AI assistants—Claude 3.7, Gemini 2.5, and GPT-4o—to help you understand which performs best in a real-world scenario: meetings.
How We Evaluated AI Models (Ft.Meetings)
Meetings are an essential part of effective team collaboration. However, they often fail to fulfill their full potential due to memory gaps. Valuable discussions frequently become ephemeral, buried deep within Slack channels or neglected in Notion pages. We recognized this common issue and conducted thorough, practical evaluations of leading AI models, focusing specifically on clarity, adaptability, responsiveness, and memory retention.
Using real-world meeting environments, we tested each AI assistant’s capability to:
- Accurately capture detailed conversation points.
- Quickly generate meaningful and clear summaries.
- Seamlessly identify and articulate actionable next steps.
- Maintain conversational context and nuance.

How We Tested The Models
##### Claude 3.7 Review
Claude 3.7:Claude 3.7, developed by Anthropic, excels in structured and detail-oriented tasks. In evaluations involving legal documents, compliance checks, and detailed code audits, Claude demonstrated unmatched precision. However, in our dynamic, conversational meeting tests, Claude’s performance was hindered by its rigidity and slower responsiveness, diminishing its effectiveness in real-time collaborative environments.
Strengths: unmatched precision, top scores on SWE-bench (70.3%).
Weaknesses: rigid in dynamic conversations, slower response speed.
Best for: legal teams, auditors, technical reviewers.
##### Gemini 2.5 Review
Gemini 2.5: Gemini 2.5 by Google marked a significant advancement in multimodal AI capabilities, effectively handling diverse data types such as images, audio, spreadsheets, and integrating seamlessly within Google Workspace. Google designed Gemini 2.5 Pro explicitly to rival OpenAI’s advanced "o" series, and it showed remarkable performance. On the SWE-bench Verified (software development capability test), Gemini scored 63.8%, performing better than OpenAI’s o3-mini and DeepSeek’s R1 but lagging behind Anthropic’s Claude 3.7 Sonnet, which scored 70.3%.
Strengths: smooth Google integration, versatile data handling, SWE-bench score of 63.8%.
Weaknesses: struggles with conversational nuance, limited customization.
Best for: productivity tasks inside Google Workspace.
However, despite the impressive benchmark, Gemini's limited conversational nuance, low customization potential, and challenges in capturing subtle real-time conversational details limited its practical effectiveness for meeting-based applications.
##### GPT-4o Review
GPT-4o by OpenAI:In our real-world evaluations, GPT-4o clearly emerged as the superior AI assistant for meetings. GPT-4o demonstrated exceptional responsiveness and adaptability, effortlessly capturing and summarizing conversational nuances with striking accuracy. It balanced clarity, readability, and actionable insights seamlessly, establishing a new standard in real-time meeting memory.
Specifically, GPT-4o:
- Consistently generated natural, human-like summaries.
- Effectively converted conversational nuances into clear, actionable tasks.
- Maintained context flawlessly, demonstrating an intuitive understanding of complex discussions.
Weaknesses: shorter long-context span compared to Claude.
Best for: dynamic team workflows, client meetings, brainstorming.
GPT-4o effectively combined human-like conversational memory with powerful machine processing, ensuring exceptional performance in dynamic team workflows.
Why Shadow Selected GPT
At Shadow, we prioritize AI solutions that genuinely simplify and enhance meeting workflows. GPT perfectly met our core criteria:
1. Natural Clarity: Produces conversational, engaging, and easily understandable summaries. 2. Context Awareness: Precisely captures subtle conversational cues, turning them effortlessly into clear, actionable items. 3. Consistent Reliability: Delivers stable performance across various meeting scenarios and diverse conversation types. 4. Rapid Responsiveness: Quickly adapts and responds to ongoing dialogue without noticeable lag or delay.
By eliminating friction rather than adding complexity, GPT-4o significantly enhances productivity and team effectiveness. Here’s why bot-free design matters.

The Future Isn’t Fewer Meetings—It’s Enhanced AI Memory
Meetings are essential, and effective meetings rely heavily on shared memory. When memory is enhanced by powerful AI:
- Decisions are more likely to be retained and acted upon.
- Tasks are completed with greater consistency and clarity.
- Team trust and cohesion are significantly improved.
Final Thoughts
Truly effective AI doesn’t need loud claims—it quietly and reliably proves its worth.
At Shadow, we’ve created exactly that—a subtle, highly efficient AI memory system powered by GPT, designed to empower your team by allowing them to focus solely on meaningful work.
