Editorial Verdict
Best for
Patent litigators at law firms (Am Law 100 to boutiques) producing trial-ready claim chartsIn-house IP teams handling litigation prep and infringement detectionPatent attorneys automating invalidity analysis and prior art searchIP business development teams identifying new case opportunities
Not ideal for
Patent prosecutors or application drafters (litigation-focused, not prosecution)Individual inventors or small firms on tight budgets (Pro plan is $625/user/month)Teams needing a free or low-cost tool (no free tier beyond trial)Users requiring mobile or offline access (web-only platform)
If your practice does frequent patent litigation, &AI can save days of manual charting and prior art search. But the $625/user/month price and credit model make it a tough sell for smaller firms or occasional use.

About &AI (YC S24)
PaidAdvancedNo APIWeb
&AI is a specialized AI platform for patent litigators—law firms from Am Law 100 to boutiques and in-house IP teams—who need to produce court-ready work product faster. It combines prior art search (patents, non-patent literature, products), element-by-element claim chart generation with citations, and drafting of invalidity contentions, expert reports, and pitch materials. Key features include a personalized feed of new litigation opportunities, Andy the AI assistant for document generation, portfolio tables for structured infringement analysis across thousands of documents, and figure annotation for claim charts. With enterprise-grade security (SOC 2 Type II, SSO, RBAC, single-tenant options) and a subscription-plus-credits pricing model, &AI is purpose-built for the patent litigation lifecycle—from opportunity identification to final export to Word, PowerPoint, or Excel. Unlike general legal AI tools, &AI is laser-focused on patent litigation and backed by an advisory board of leading patent litigators.
Behind the Verdict
&AI is a rare breed: a vertical AI tool built by patent lawyers for patent lawyers. It actually understands what a claim chart needs—element-by-element citations, claim construction from prosecution history, and export formats that judges accept. The integration of prior art search, charting, and drafting in one workspace is genuinely useful, and the new figure annotation feature (July 2026) adds precision to infringement analysis. Where it bites is the pricing: $625/user/month for Pro with 2,500 credits (then $0.25/credit) adds up fast if you're generating many charts. The Enterprise tier with SSO and custom models is appropriate for large firms, but the per-user cost still stings. The closest alternative is a combination of traditional search tools (like LexisNexis IP) and manual charting—which is slower but has no credit limits. For a firm handling 10+ patent cases a year, &AI pays for itself in time saved. For a solo practitioner or low-volume team, the credits model may feel restrictive. Also, it's web-only—no mobile or offline access, which could be inconvenient for court or travel. We'd recommend the 7-day free trial to validate the ROI for your specific workflow before committing.
