Starting with Assistant
Harvey’s Word Add-In is driven by an Agent that has powerful planning, reasoning, and reviewing capabilities. From your prompt, it will automatically determine the right approach and builds a step-by-step action plan tailored to the document and task at hand.
Note: You may experience a slower response on your first prompt as Harvey familiarizes itself with your document. Follow-up prompts in the same thread typically yield faster responses.
Analysis Use Cases
You can ask questions on highlighted text or the full document without needing to access Harvey in your browser.
- Type your query in the prompt text box (e.g., "What are the risks with this clause?”) or, choose a suggested prompt.
- [Optional] Click the + icon to include precedent documents from Vault or from a local folder to inform Harvey's responses. You may also have the option to select Web Search as a knowledge source if it’s enabled in your workspace.
- [Optional] Click Improve prompt to enhance your query so that results are more accurate and relevant.
- Click the arrow to run your query.
Editing Use Cases
In Assistant you can make changes to your Word document through Harvey's suggestions and edits. Redline your document, either over specific text or over the full document. Then give Harvey natural language instructions (e.g., “Make this more in line with the uploaded precedent terms.”).
Note: You can prompt Harvey to populate or edit tables and Harvey will suggest text to fill in or amend content within tables.
Follow the steps below to get started.
- Select text you’d like to edit, or place your cursor where new content should go.
- Add your instructions in the prompt text box.
- [Optional] Click the + icon to upload a precedent to guide Harvey’s suggestions. You may also have the option to select Web Search as a knowledge source if it’s enabled in your workspace. You can view sources of information in the thinking state dropdown.
- Click the arrow to run your query. Harvey will consider the specific legal context, jargon, and instructions provided to generate precise suggestions.
- Review and apply changes. Auto-apply the suggestions, or review them individually to choose which ones to apply to the selected text.
- Accepted changes are applied as redlined tracked changes in the document, while dismissed suggestions are not applied.
Tip: Avoid making changes while Harvey is working on a response. Editing during the Harvey's “thinking” state can cause errors.
Sample use cases
Here are a few prompt ideas for testing out this feature:
- Mark up this document to be more in line with the terms agreed to in uploaded precedents
- Make updates based on meeting notes
- Replace all instances of Party X with Party Y
- Fill out this template in accordance with the precedent
Drafting Use Cases
Use Assistant to create new documents in Word directly through Harvey’s drafting capabilities. This can be useful when starting from a blank document or when you want Harvey to generate a first draft based on your instructions.
For example, you can open a new Word document, ask Harvey to “draft a NDA,” and optionally upload a sample NDA for reference.
Using Workflows
Apply a workflow to execute tasks more efficiently. Try one of the following workflows to get started.
Redact

- Of the redacted material, 95-99% is actually PII
- You can select any combination of preset redaction categories before generating redlines
- The original document will be unchanged, Harvey creates a new redacted copy
Convert to Template
Convert a document into a reusable template to standardize frequently used documents, such as engagement letters or NDAs, without manually removing client-specific details.
- When you select Convert to a Template, Harvey will scan your document and automatically identify personalized or variable information. This includes names, addresses, company names, dates, and contact information.
- These details will be replaced with labeled placeholders (e.g., [Name], [Address], [Date]) to create a clean, reusable template.
- You’ll have the opportunity to review, add, and edit all suggested placeholders before saving the final version in your workspace.

How Does Uploading a Precedent Improve Results?
When you upload a precedent(s), Harvey can automatically suggest changes to clauses, ensuring they align with successful language from past documents. When drafting or reviewing, leveraging proven precedents helps streamline language, ensuring efficient, consistent results. You can review and selectively apply these precedent-based suggestions to achieve optimal outcomes with greater confidence.
Example: If a strong non-solicitation clause is needed, and previous agreements (e.g., ABC123 and DEF456) have proven effective, Harvey will suggest edits that incorporate similar language. This approach enables drafters to rely on language with a proven track record to meet client needs.
