Feature-by-feature
Harvey is a comprehensive legal AI platform offering features like AI Assistant for drafting and Q&A, Vault for secure document storage, Knowledge for multi-domain legal research, and Agents for automating complex legal workflows. It also provides Contract Intelligence with negotiation insights, Command Center for analytics and governance, Shared Spaces for cross-organization collaboration, and a mobile app. Proofly, on the other hand, is a focused Chrome extension that uses on-device Gemini Nano AI to proofread for spelling, grammar, punctuation, and capitalization errors in real time. It offers underlines, popover corrections, a sidebar listing all issues, and optional auto-correct. While Harvey integrates with enterprise tools like Slack, Teams, Relativity, iManage, and Microsoft Office, Proofly has no integrations—it's a standalone extension. Harvey's latest news highlights its $11B valuation, underscoring its enterprise traction. Proofly's recent v0.6.0 release shows ongoing refinement. In short, Harvey is a full legal workflow automation suite, while Proofly is a lightweight, privacy-first proofreader.
Pricing compared
Harvey uses a contact-based pricing model, typical for enterprise legal platforms. There is no public pricing or free tier, making it inaccessible for individuals or small teams without significant budget. Proofly is completely free, open-source, and requires no account or payment. For a solo practitioner or small firm, Proofly offers a zero-cost entry to basic proofreading, but lacks the legal-specific capabilities of Harvey. If you're a large law firm, Harvey's pricing likely aligns with its extensive feature set, but you'll need to negotiate. For most individual users, Proofly's free model is unbeatable.
