Where can I find a program for writing research paper using AP style?

There isn't a single program specifically designed for writing research papers *only* in AP style. Word processors like Microsoft Word and Google Docs are the most common tools, and you'll need to use their features in conjunction with the AP Stylebook to format your paper correctly.

Here's what you can do:

* Use a word processor's built-in features: Both Microsoft Word and Google Docs offer features to help with formatting, including:

* Styles: You can create custom styles to match AP style requirements for headings, paragraphs, citations, etc. This is the most efficient way to ensure consistency.

* Spell and grammar check: While not specifically AP-style focused, these tools can help with basic writing errors.

* Use a citation manager: These programs (like Zotero, Mendeley, or EndNote) help manage your sources and automatically generate citations and bibliographies in various styles, including AP style (though you'll likely need to verify accuracy).

* Consult the AP Stylebook: This is the definitive guide to AP style. You'll need to refer to it throughout your writing and editing process to ensure accuracy. The AP Stylebook is available in print and online.

* Consider online AP style guides and resources: Several websites offer summaries and explanations of AP style rules. These can be helpful supplements to the main Stylebook.

In short, the "program" is the combination of your chosen word processor, a citation manager (optional but recommended), and the AP Stylebook itself. There's no single software package that does it all automatically. You'll need to actively use the style guide and apply its rules as you write and format your paper.
