&AI (YC S24)
AI workspace for patent litigators: prior art search, claim charts, infringement detection, and BD.
&AI is the most purpose-built patent litigation AI we've tested, with real workflow depth for claim charts, prior art search, infringement detection, and business development. Unlike horizontal legal AI like Harvey or general-purpose Claude, &AI is designed for patent-specific workflows—element-by-element charts, invalidity contentions, and evidence-of-use detection. The credit-based pricing is transparent but can get expensive for heavy users; at $0.40/credit, a single claim chart averages $96. However, Pro credits at $0.25 each make it cost-effective for regular litigation. If you're a litigator who needs court-ready work product, this is worth the investment; occasional users should

Skip &AI if you are a patent prosecutor, individual inventor, or small firm on a tight budget, because the credit-based pricing and lack of free tier make it expensive for occasional use, and it lacks mobile/offline access.
Credits add up fast: a single claim chart averages 241 credits costing $96 with pay-as-you-go, so heavy usage will require the Pro plan to stay affordable.
The credit-based model aligns costs with usage, making it flexible for varying workloads. For regular litigation, Pro at $0.25/credit is more cost-effective than pay-as-you-go at $0.40 and beats horizontal tools that charge flat seats for features you may not use. However, it's pricier for light users compared to general legal AI like Harvey.

About &AI (YC S24)
&AI is a specialized AI workspace built for patent litigators who need to produce trial-ready work product—fast enough for pitches, strong enough for court. It combines real-time prior art search across patents, non-patent literature, and products with element-by-element claim chart generation that includes automated citations and figure annotation. You can also draft invalidity contentions, expert reports, and pitch materials directly from templates, and the Andy AI assistant turns instructions into high-quality drafts. Backed by an advisory board of partners from firms like Fish & Richardson and DLA Piper, &AI is designed for the demands of high-stakes IP disputes. In 2026, the platform moved to fully self-serve credit-based pricing, aligning costs with actual work. Security is enterprise-grade: SOC 2 Type II certified, zero data retention, no training on your data, SAML SSO, RBAC, and optional single-tenant or self-hosted deployment.
Behind the Verdict
&AI is a purpose-built tool that understands the nuances of patent litigation. Its core strength is the integration of search, chart generation, and drafting into a single workflow. The claim chart generation is exceptional: it produces element-by-element charts with citations to prior art and product documentation, and the figure annotation feature—highlighted in a July 2026 blog post—automates the 'teach-in' while keeping human control. The prior art search covers patents, NPL, and products in real time, which is critical for thorough validity analysis. For business development, the Opportunities add-on provides a personalized feed of new litigation cases, triaged to the right partners based on prior experience—a feature we haven't seen in other legal AI tools. However, &AI is not for everyone. It's expensive for occasional use: a single claim chart consumes an average of 241 credits, costing $96 at pay-as-you-go rates. The Pro plan at $625/user/month is aimed at regular litigation workflows. There's no free tier—only a 7-day trial. And while the platform is web-based, it lacks mobile and offline access, which may be a limitation for some. Compared to Harvey, which is a general legal AI, &AI is specifically designed for patent litigation. As a July 2026 blog post highlights, &AI addresses needs not met by horizontal tools: claim chart automation, infringement detection, and BD workflows. If patent disputes are a core part of your practice, &AI is the best-fit tool we've seen. If you only occasionally handle patent work, a general tool like Claude or Harvey might suffice. Security is a standout: SOC 2 Type II, no training on your data, zero retention, SAML SSO, RBAC, and option for single-tenant/self-hosted. The advisory board includes partners from top IP firms, lending credibility. In summary, &AI is a powerful niche tool that excels at its core use cases. It's not a general-purpose assistant, but for patent litigators, it's the most comprehensive solution we've tested.
