Code Comment Generation Artificial Intelligence (AI) Global Market Report 2025

The code comment generation artificial intelligence (AI) market size has grown exponentially in recent years. It will grow from $0.68 billion in 2024 to $0.88 billion in 2025 at a compound annual growth rate (CAGR) of 30.9%. The growth in the historic period can be attributed to rising adoption of agile development methodologies, increasing complexity of software systems, growing demand for developer productivity tools, growth of open-source software and collaborative coding, and increasing focus on software maintainability and technical debt reduction.

The code comment generation artificial intelligence (AI) market size is expected to see exponential growth in the next few years. It will grow to $2.57 billion in 2029 at a compound annual growth rate (CAGR) of 30.5%. The growth in the forecast period can be attributed to rising integration of artificial intelligence in software development lifecycles, increasing reliance on large language models for code comprehension, growing need to modernize legacy enterprise systems, rising demand for automated DevOps and MLOps practices, and increasing investment in artificial intelligence (AI)-powered software development tools. Key trends in the forecast period include advancement in context-aware artificial intelligence for cross-file code understanding, development of real-time collaborative commenting in IDEs, innovation in artificial intelligence-generated documentation for legacy code migration, integration of code commenting with automated testing and continuous integration and continuous delivery pipelines, and emergence of customizable artificial intelligence models trained on proprietary codebases.

The increasing adoption of cloud computing is expected to drive the growth of the code comment generation artificial intelligence (AI) market going forward. Cloud computing refers to on-demand access over the internet to shared computing resources such as servers, storage, databases, and software provisioned and released with minimal management effort. The shift towards cloud computing is driven by enterprises seeking scalable and flexible infrastructure that can handle variable workloads efficiently. Code comment generation artificial intelligence supports this shift by automatically producing accurate in-line explanations and docstrings for cloud-native, distributed codebases, improving maintainability, onboarding speed, and standardized knowledge capture. For instance, in January 2025, according to AAG IT, a UK-based IT services company, an estimated 63% of small and medium-sized business (SMB) workloads and 62% of SMB data were expected to be hosted in public clouds by 2023, up from 57% of workloads and 56% of data in 2022. Therefore, the increasing adoption of cloud computing is fueling the code comment generation artificial intelligence (AI) market.

Key companies operating in the code comment generation artificial intelligence (AI) market are focusing on developing integrated-development-environment large-language-model documentation-comment generation to accelerate authoring of consistent, high-quality comments and enhance maintainability across codebases. Integrated-development-environment large-language-model documentation-comment generation involves embedding a context-aware large language model inside the developer’s editor so it reads surrounding source, symbols, parameters, and return types, then synthesizes structured documentation comments in place without switching tools. For instance, in March 2025, Microsoft, a US-based technology company, launched automatic documentation comment generation in Visual Studio 2022 version 17.14 Preview 2, powered by GitHub Copilot. A key feature of the tool is its ability to instantly create clear, properly formatted documentation comments for C# and C++ functions when a developer uses the standard comment shortcut and confirms the prompt. This automation streamlines the documentation process, maintains uniformity across projects, and keeps comments directly connected to the source code, improving API clarity and team-wide development efficiency.

In May 2025, OpenAI, a US-based artificial intelligence company, acquired Windsurf for $3 billion. Following the acquisition, ChatGPT is expected to gain enhanced coding abilities, strengthening its performance in assisting developers. The deal also positions OpenAI to compete more effectively within the growing market of AI coding tools that translate natural language into executable code. Windsurf is a US-based company specializing in code comment generation artificial intelligence (AI) solutions.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid escalation of U.S. tariffs and the resulting trade tensions in spring 2025 are significantly impacting the information technology sector, particularly in hardware manufacturing, data infrastructure, and software deployment. Higher duties on imported semiconductors, circuit boards, and networking equipment have raised production and operational costs for tech firms, cloud service providers, and data centers. Companies relying on globally sourced components for laptops, servers, and consumer electronics are facing longer lead times and increased pricing pressures. In parallel, tariffs on specialized software tools and retaliatory measures from key international markets have disrupted global IT supply chains and reduced overseas demand for U.S.-developed technologies. To navigate these challenges, the sector is accelerating investments in domestic chip fabrication, diversifying supplier bases, and adopting AI-driven automation to enhance operational resilience and cost efficiency.
