Claude
AI assistant and API
Long-context assistant with a developer API built for tool use.
Anthropic's assistant is available as a chat app and as an API. Most Loopwise tutorials use the API because it is easy to script and it handles long documents and structured output well.
A good fit if
- Summarising and extracting data from long documents
- Code review, refactoring and explaining unfamiliar code
- Building agents that call your own functions (tool use)
Skip it if
- You need image generation inside the same product
- Your team is locked into another vendor's enterprise contract
Pricing
A free plan exists for the chat app. API usage is billed per token, so check the current price list before you budget.
This profile summarises what the tool is for. Plans, limits and features change often, so confirm the details on the official site before you decide.
