AI-Review.net — AI Market Share Tracker

General AI assistants proxy share

Relative consumer/web usage index. Useful for direction, not audited MAU market share.

Release markers: ChatGPT (Nov 2022), Claude (Mar 2023), Gemini model family (Dec 2023). Series are normalized illustrative trend estimates anchored to public traffic/adoption reports.

AI coding tools survey measured

% of professional developers using each tool at work. Multi-select; lines do not sum to 100%.

JetBrains Developer Ecosystem / AI Pulse surveys. Known points include Jan 2026 and May–Jul 2026. Intermediate points are visually interpolated.

Enterprise foundation-model share spend / usage

Estimated share of enterprise LLM API usage / spend.

Menlo Ventures: OpenAI ~50%→27% (2023→2025), Anthropic ~12%→40%, Google ~7%→21%. Remainder grouped as Other.

Open-weight model ecosystem proxy share

Illustrative share of open-model usage across developer/startup channels.

Enterprise open-weight share is about 11% of total LLM usage in Menlo's 2025 estimate. Family-level trend below is a proxy inspired by vLLM/OpenRouter ecosystem direction.

AI image generation traffic / usage proxy

Standalone + embedded product share is difficult to measure; this chart is intentionally labeled as a proxy.

Embedded image generation inside ChatGPT and Gemini makes standalone-web market-share comparisons incomplete.

AI video generation traffic / usage proxy

Relative product adoption proxy across major video-generation platforms.

Veo and Sora distribution is partly embedded inside broader ecosystems; Runway/Kling/HeyGen have clearer standalone traffic signals.

Release timeline

Key launches used as context markers. “Release” refers to public product/model availability, not company founding date.

Data methodology

Enterprise APIs: Menlo Ventures 2025 State of Generative AI in the Enterprise. 2023–2025 values are reported/estimated by Menlo.

Coding: JetBrains Developer Ecosystem Survey 2026 and AI Pulse research. Multi-tool adoption means percentages can exceed 100% when summed.

Assistants: Public consumer-adoption and web-traffic reports. Because platforms report MAU differently, this demo uses a normalized share proxy.

Image / Video: Public traffic and ecosystem signals. Embedded generation makes a universal denominator unavailable; values are illustrative until a consistent dataset is licensed or collected.

Release dates: Official vendor announcements where available. Dates should be stored independently from chart observations in production.

Production recommendation: Store each observation as {date, category, product, metric, value, denominator, geography, source_url, confidence} and render from an API rather than hard-coded arrays.
