How to use Claude

For long-document tasks, it is recommended to first organize the materials into a clear structure before asking questions, which will significantly improve the quality of answers.
for multi-round complex tasks, you can break them down step by step, letting the AI digest them section by section instead of inputting them all at once.
For long documents, you can also paste them section by section and confirm section by section.
For code-related tasks, provide the "goals + constraints + error messages" all at once to reduce the number of rounds of back-and-forth clarification.
use Artifacts to preview the output in real time and make revisions while viewing.
The free version is suitable for low-frequency trial use.
For heavy usage, it is recommended to choose Pro or Max based on actual usage.
For team scenarios, prioritize the enterprise version for unified management of accounts, permissions, and usage, and it also facilitates the accumulation of team-level usage specifications.

Things to know

The free version has usage limits, and response speed during peak hours as well as available models may be restricted. It is recommended to perform important tasks during periods with sufficient credits. When integrating products via APIs, different models have significant differences in context windows, rate limits and pricing. When selecting a model, check the official documentation item by item and reserve test credits to verify the effect. AI-generated content may contain errors; please retain manual verification for code and factual conclusions, especially for content related to security and compliance. When handling sensitive data, pay attention to verifying data usage and retention policies, and enterprise users should confirm the organization's terms for data training and storage.
