Practical tips for better results
For code and data, work on a copy, remove secrets before pasting examples, and test results in the intended environment before deploying.
Start with the smallest useful task rather than a long, vague request. Keep input values consistent, review the result in context, and make a correction if the result does not match what you expected. If the tool produces text, treat it as a draft until you verify the facts and tone. If it processes a file, compare the output with the original before sharing it.
What to know before using it
Formatting verifies JSON syntax, not whether the data is correct for a particular API schema. Do not paste secrets or tokens into public/shared computers.
CeveoAI labels tools based on their intended operating mode. A browser utility can work locally, while a provider-powered feature needs working credentials and server configuration. The presence of a tool page does not mean a third-party integration is active. Never place API keys in frontend code or paste passwords and sensitive records into prompts.
