eety.ai — AI Patent Drafting Assistant

About this app

eety.ai is a game-changer for patent professionals, offering an AI assistant that doesn't replace you but works alongside you like the best junior associate you've ever had. It's designed to handle the heavy lifting of patent drafting—from analyzing disclosures and generating claims to creating USPTO-compliant drawings—while you retain full control over strategy and style. The tool stands out with its deep comprehension engine, which builds a living mental model of your invention, asks targeted technical questions instead of making assumptions, and adapts to your unique writing voice. With a 10-phase drafting pipeline, natural communication interface, and enterprise-grade security, eety.ai streamlines the entire patent application process, saving time and reducing errors for legal experts and innovators alike. It's perfect for those tired of generic AI tools and seeking a collaborative, efficient solution that respects their expertise.

Key features

115-point deep comprehension engine builds persistent 'living mental model' with per-dimension confidence scoring before drafting begins
2Natural language chat interface + style intelligence that adapts to your specific writing voice, hedging, and claim formatting
310-phase structured pipeline including USPTO-compliant iterative drawing generation, prior art analysis, and multi-source surgical merging

Target customer profile

Drawn from the product itself, not from a survey.

Demographic

Patent attorneys and agents at law firms or corporations

Pain points

Time-consuming manual drafting, high workloads, risk of errors in claims or specifications, and generic AI tools that lack legal nuance.

Primary needs

Efficient drafting with precision, maintaining legal strategy control, reducing turnaround time, and ensuring USPTO compliance without sacrificing quality.

Demographic

In-house IP teams at tech startups or R&D companies

Pain points

Limited resources for patent filings, need to protect innovations quickly, and balancing cost with thorough patent coverage.

Primary needs

Cost-effective patent drafting, fast provisional filings, seamless integration with internal workflows, and tools that scale with growing IP portfolios.

Demographic

Independent inventors and solo practitioners

Pain points

High costs of hiring full legal teams, complexity of patent law, and lack of access to advanced drafting tools.

Primary needs

Affordable, user-friendly assistance, guidance through the patent process, and support for drafting without extensive legal background.

Scout Review

Written by AI from measured evidence, scored out of 100.

eety.ai stands out as one of the more thoughtful AI patent drafting tools available. Instead of rushing to generate text like many competitors, it prioritizes building a structured 'living mental model' of the invention through 15 analysis dimensions, confidence scoring, and targeted clarification questions. The combination of style adaptation, iterative USPTO-compliant drawing generation, natural chat interface, and strong security makes it feel like a true collaborative partner rather than a blunt instrument. It's particularly strong for patent attorneys and in-house teams who value control, precision, and legal nuance over pure speed. While the pricing may deter very low-volume users, the quality of output and workflow integration deliver clear ROI for regular filers. Early signs suggest it's solving real pain points that generic AI and simpler template tools miss.

Measure by measure

Usability

Natural language chat interface lets you say 'widen the independent claims' or 'these are garbage, restart'. Builds living mental model via targeted inventor questions instead of assumptions. 10-phase pipeline with confidence scoring keeps you in control.

Design

Purpose-built workspace integrates rich document editor, real-time AI chat, drawings gallery, understanding panel, style profiler, and progress tracking. Clean, professional UI tailored for patent pros with track changes and one-click USPTO DOCX export.

Speed

30 seconds per document for 15-point deep analysis. Drawings regenerate in seconds. Full pipeline produces first-quality drafts significantly faster than manual work. Priority processing in paid plans.

Security

Enterprise-grade with private storage, no public URLs, tenant isolation, JWT access control, full audit trails. Explicitly states your patent data is never used to train models. Strong focus on trust for IP professionals.

Accessibility

Growth

Subscription model (≈$22-27 per patent in bundles of 75-200). Targets law firms, in-house teams, and independents. Early positive Reddit feedback on efficiency gains. API and team features in higher plans support scaling IP portfolios.

Improvement areas

Provide more transparent, quantified benchmarks on claim quality, enablement strength, and time savings from real customer deployments
Consider more flexible pricing for low-volume solo practitioners and independent inventors
Expand native integrations with popular IP docketing and prior art search platforms

Design & Usability

eety.ai nails the collaborative 'brilliant junior associate' vibe. The purpose-built environment combines document editing, live AI chat, visual drawings gallery, and a dedicated 'Brain' panel showing the 15-point invention model with color-coded confidence scores. Natural language commands feel conversational rather than robotic. Style intelligence that learns your hedging patterns and claim formatting from example patents is genuinely impressive. It asks targeted technical questions instead of assuming, which keeps attorneys in the driver's seat. Compared to generic tools, this feels like it was built by people who understand patent strategy isn't just text generation. The 10-phase SOP (Disclosure Analysis through Quality Review) provides structure without rigidity.

Speed & Security

Analysis happens in ~30 seconds per document with multi-source merging that preserves your previous work via surgical updates. Iterative drawing generation is fast enough for real back-and-forth. Enterprise security is a standout — private per-tenant storage, no training on your data, full audit trails. This matters enormously in IP where leaks or model contamination are nightmares. It produces USPTO-compliant drawings with consistent reference numerals and proper formatting. The confidence scoring guardrails (blocking drafting on red/amber foundations) add a layer of quality control that cheaper template-based tools completely lack. Overall it delivers measurable time savings on the heavy lifting while reducing error risk.

Accessibility & Growth

The 5 free drafts (no card needed) lowers the barrier for independent inventors and solo practitioners who otherwise face high legal costs. Natural chat interface makes it more approachable than rigid form-based tools. Growth is supported by tiered plans that scale with volume — higher tiers unlock team collaboration, custom style templates, API access, and priority processing. Early user feedback on Reddit highlights real efficiency gains once past the learning curve. It serves in-house teams at startups needing fast provisionals and law firms drowning in workload. While not the cheapest option, the depth of comprehension and compliance focus justifies the investment for serious patent work.

Conclusion

If you're tired of AI that confidently spits out garbage claims or drawings that look like a 5th grader made them in Visio, eety.ai is worth the trial. It respects your expertise, learns your voice, and handles the tedious parts so you can focus on strategy. The future of patent drafting isn't replacement — it's amplification. This tool gets that.

Suggestions for improvement

Add more public case studies or quantified time-saving metrics from real law firm deployments to build credibility.
Introduce a lower-volume monthly subscription option for solo practitioners who file 1-3 patents per month.
Expand integrations with popular IP management platforms (like Anaqua or Docket Navigator) beyond basic DOCX export and API.
Publish a public benchmark comparing its claim quality and enablement strength against leading competitors on standardized invention sets.
