Where the guidance comes from

The tool's behavior is defined by this site's code and is tested locally. General writing guidance is linked to its publisher.

External writing guidance

AI provider

AI mode is served by DeepSeek through this site's own endpoint, using the deepseek-flash model at its api.deepseek.com endpoint (see DeepSeek API Docs). DeepSeek's identity and processing terms are stated on the privacy page, and the provider's own documents are DeepSeek Privacy Policy and DeepSeek Open Platform Terms of Service. The label definitions used for fact, opinion, and inference follow the distinction between reported claims and evaluative statements discussed in the Purdue guidance above; they are the site's own operational definitions and are not adopted from any one publisher.

Site-specific method

The tool's selection logic, character limit, offsets, phrase cues, and quote verification rules come from the local implementation described in How it works. These are statements about this product, not claims borrowed from Purdue. The tool does not certify the accuracy or rights status of user-pasted text.
