AI Writing Assistant API

What it does

AI Writing Assistant helps you generate citations, check grammar and spelling, and outline a user manual from structured prompts. Send the specific text or document details each endpoint needs, and get back a formatted result you can use directly in your app.

Use Citation Generator when you need APA, MLA, or Chicago references. Provide style, authors, title, and optional url, year, and siteOrPublisher, then receive a single formatted citation in result along with the tool name.

Use Grammar & Spelling Checker for plain text review. Send text and get a result object with the corrected version, a count of corrections, a list of issues, suggestions, and the rule-based method used. That makes it useful for editor workflows, support content, and any user-generated copy that needs a quick cleanup.

Use User Manual Outline Generator to turn a product name and task list into a manual outline. Provide product and tasks, and it returns a title plus ordered sections, including one "How to" section per task. That fits onboarding docs, help centers, and internal enablement content.
