Detailed recommendations
I want a general-purpose AI chatbot or assistant
Use OpenAI. GPT models are the most versatile option. They handle chat, content generation, code writing, summarization, and classification well. OpenAI has the largest ecosystem and the most community examples.
Add an AI chat assistant to my app using OpenAI. Include a message history,
streaming responses, and a text input with a send button.
I need careful, nuanced content or analysis of long documents
Use Anthropic. Claude excels at tasks that require careful reasoning, following complex instructions, and producing nuanced, well-structured long-form content. It handles very large context windows, making it ideal for analyzing long documents.
Build a document analysis tool using Anthropic Claude. Users upload a PDF,
and the app generates a structured summary with key findings and recommendations.
Build an image description tool using Gemini. Users upload a photo
and the app generates an alt text description, color palette, and mood analysis.
I need factual answers with cited sources from the web
Use Perplexity. Perplexity is an AI-powered search engine that returns answers with inline citations. It is the best choice when accuracy and source verification matter more than creative generation.
Build a research assistant using Perplexity. Users type a question
and the app returns a summarized answer with numbered source citations.
I want to use multiple AI models in the same app
Connect multiple integrations. You can connect OpenAI, Anthropic, Gemini, and Perplexity to the same project. Use different models for different features based on their strengths.
Build a writing assistant that uses OpenAI for drafting, Anthropic for editing
and fact-checking, and Perplexity for research with citations.
