ChatGPT vs Gemini

ChatGPT

OpenAI's conversational AI assistant

ChatGPT is an AI assistant from OpenAI. People use it to ask questions, write and edit text, brainstorm, analyse documents and data, write and debug code, generate images, learn new subjects and carry out tasks, through a conversational interface on the web, desktop and mobile apps. Its launch in November 2022 marked a turning point for artificial intelligence. ChatGPT reached a huge user base faster than almost any consumer product before it, introduced the general public to large language models and started the wave of generative AI products and investment that followed. It remains the most widely used AI assistant. The product has expanded far beyond text chat. It can search the web and cite sources, analyse uploaded files such as PDFs and spreadsheets, run code to analyse data and create charts, generate and edit images, and hold real-time voice conversations. Custom GPTs let users and companies build specialised assistants for particular tasks, projects organise chats and files around a goal, memory allows it to remember preferences across conversations, and deep research produces long, sourced reports on complex questions. Agent capabilities let it carry out multi-step tasks on the web on the user's behalf. ChatGPT has a free tier and paid subscriptions that offer more capable models, higher usage limits and advanced features, plus Team and Enterprise plans with administration, privacy commitments and data controls for organisations. Developers access the underlying models separately through OpenAI's API. The limitations are those of current language models. It can state incorrect information confidently, its knowledge has cut-off dates unless it searches, and outputs need checking for important decisions. Privacy and data-handling policies matter for sensitive information, and organisations often prefer business plans that exclude their data from training. Alternatives include Claude from Anthropic, known for writing quality and long documents; Google Gemini, integrated with Google's services; Microsoft Copilot for Microsoft 365 users; Perplexity for answer-engine search with citations; Meta AI inside Meta's apps; and Mistral's Le Chat. Choose ChatGPT when you want the most widely used general-purpose AI assistant with a broad feature set.

Gemini

Google's AI assistant and model family

Gemini is Google's AI assistant and the name of its family of AI models. The Gemini app helps people write, plan, learn, research, code, and create images and video, and Gemini models power AI features across Google's products, including Search, Workspace and Android. Its biggest advantage is integration with Google's ecosystem. Gemini can work with information in Gmail, Google Docs, Drive, Calendar, Maps and YouTube, so it can summarise emails, draft documents from files, plan trips with real places or answer questions about a video, with permission from the user. On Android phones it serves as an assistant that can understand what is on screen and take actions, and Gemini Live supports natural voice conversations, including camera and screen sharing so the assistant can see what the user sees. The models are built to be multimodal, handling text, images, audio, video and code, and they support long context, which lets Gemini analyse long documents, large codebases or lengthy videos. Features such as Deep Research produce detailed reports from many web sources, Gems let users create custom assistants for repeated tasks, and NotebookLM, a related Google product, turns uploaded sources into summaries and audio overviews. Image and video generation use Google's generative media models. Gemini is free to use with limits, and Google's AI subscription plans provide access to more capable models, higher limits, more storage and Gemini inside Workspace apps. Businesses access Gemini through Google Workspace and Google Cloud, and developers through the Gemini API and Vertex AI. The trade-offs are familiar for AI assistants: answers can be wrong and need checking, and connecting personal data raises privacy considerations that users should review. Its value is greatest for people already using Google services heavily. Alternatives include ChatGPT, the most widely used assistant; Claude from Anthropic for writing and long documents; Microsoft Copilot for Microsoft 365; Perplexity for cited search answers; Apple Intelligence on Apple devices; and Meta AI. Choose Gemini when you live in Google's apps and want an assistant that works across them.
