Side-by-side comparison of AI visibility scores, market position, and capabilities
ChatGPT surpassed 400M weekly active users in February 2025 and launched GPT-4o with voice, image, and real-time reasoning — the world's most-used AI product.
ChatGPT is OpenAI's flagship AI assistant, launched in November 2022 and credited with igniting mainstream consumer adoption of generative AI. It crossed 100 million users in two months — the fastest consumer product to do so in history — and reached 400 million weekly active users by February 2025. Available as a free web and mobile app with a ChatGPT Plus subscription ($20/month) unlocking GPT-4o, advanced voice mode, image generation, and longer context.
Adept AI raised $415M to pioneer computer-use AI agents; its core research and agent team moved to Amazon in 2024 in a landmark talent acquisition while the company continues developing ACT-1 for enterprise automation.
Adept AI was founded in 2022 by a team of former OpenAI, DeepMind, and Google Brain researchers to build AI that can take actions on computers — navigating software interfaces, filling forms, and executing multi-step workflows in any application. Its ACT-1 model demonstrated the ability to control web browsers and desktop applications through natural language instructions, pioneering the computer-use agent paradigm that Anthropic later commercialized with Claude's computer use feature.
