Why Other AI Platforms Fall Short

Polished interfaces can't hide fundamental design flaws

The Problem with Other Platforms

  • Constant Upselling: Every new feature locked behind a new "module" paywall—you never get the full power of AI
  • Built by Developers, Not Practitioners: Missing the subtle details that matter in real patent work
  • Rigid Workflows: Forces you into their predetermined process instead of adapting to yours
  • Style Dictation: Imposes their format and voice on your work product
  • Premium Pricing: Charges 2x what we do for access to the same underlying models

The LLM Sandbox Philosophy

  • One Token Pool, Infinite Uses: Allocate your resources to any task—new features use the same tokens you already have
  • Built by Patent Attorneys: Every detail designed by people who use these tools daily in their own practice
  • True Flexibility: A sandbox you can shape however you want—we provide tools, you decide how to use them
  • Your Style, Your Voice: System learns and matches your preferences, not the other way around
  • Honest Pricing: ~50% less than competitors because we run efficiently, not because we cut corners

Our Core Belief

Other platforms build constrained tools that oversimplify patent work. Instead of forcing you into our predetermined process, we build open-ended tools you can adapt to your needs. Your expertise should drive the tool—not the other way around.

Everything You Need for Patent Prosecution

Three core capabilities that handle the full spectrum of patent work

Draft Applications

Section-by-section drafting with AI that learns your exact writing style. Upload examples of your work, and the system matches your voice—delivering work product indistinguishable from manual drafting.

Respond to Office Actions

Comprehensive analysis and response generation for 101, 102, 103, and 112 rejections. Create custom workflows or use agent mode for autonomous execution—you control the process.

Access USPTO & EPO

Direct API access to patent databases and complete file histories. Natural language search retrieves any document—no manual downloads, no PDF extraction errors.

Why Patent Practitioners Choose the LLM Sandbox

You Drive, AI Accelerates

Most AI tools work like a train—you get on and end up wherever it takes you. The LLM Sandbox works like a car—you control exactly where you're going. You make strategic decisions at every stage while the AI handles time-consuming execution.

Draft 2-3x Faster

Draft entire detailed descriptions in minutes instead of hours. Review thousands of pages of prior art with a single prompt. The LLM Sandbox gives you "reading superpowers" that dramatically reduce repetitive analysis and eye strain.

Your Style, Your Voice

Upload 1-4 example applications and watch the system learn your exact writing style. Section-aware learning ensures backgrounds sound like the backgrounds YOU usually draft.

True Flexibility

Do anything frontier AI models can do, plus every patent-specific optimization you need. Create custom workflows, use agent mode for autonomous execution, or build your own multi-step processes. The tool adapts to you, not the other way around.

Built by Practitioners

Every detail designed by patent attorneys who use these tools daily in their own practice. You can feel the difference in the subtle details—this isn't software developers guessing what patent work requires.

Constantly Improving

As AI models improve, you automatically benefit. As model costs decrease, those savings pass directly to you. New features use the same tokens you already have—no upsells, no new "modules" to buy.

Honest Pricing: ~50% Less Than Competitors

We charge about half what other platforms do—not because we use inferior models, but because we run an efficient operation with minimal overhead. One simple token-based pricing model. No upsells. No "modules." New features use the same tokens you already have.

  • One token pool for all features
  • New features included automatically
  • Model cost savings passed to you

Frequently Asked Questions

Tokens are the universal currency for all LLM Sandbox features—drafting, office action responses, searches, figure generation, everything. While usage varies based on complexity, 100k tokens typically allows you to draft 3-4 complete patent applications, or respond to 4-8 office actions, or some combination of both. The key advantage: as we add new features, they use the same token pool you already have. No upsells, no new "modules" to buy.

No, we never train on user data. We only retain data you explicitly request (like saved conversations and custom prompts), and you can delete these at any time. Everything else—uploaded documents, generated content—is automatically deleted when you sign out. We built our system so no human ever comes into contact with your content. It's fully automated processing with zero human access. Your confidential information stays confidential.

Never. The tool is explicitly designed to augment, not replace, human expertise. You make the strategic decisions—which arguments to pursue, how to amend claims, what scope to target. The AI accelerates execution of your strategy and eliminates repetitive tasks, but your professional judgment drives every meaningful decision.

We run an efficient operation with minimal overhead, and we don't play pricing games. Other platforms constantly upsell new "modules" and lock features behind paywalls. We give you one token pool that works for everything. We actually use MORE expensive models than competitors, but our efficient operations let us pass savings directly to you. It's almost the same cost as subscribing to OpenAI or Anthropic directly.

Yes! Upload 1-4 example applications and watch the tool adapt to your exact drafting preferences. Maintain different styles for different clients, specify word counts and paragraph structure, and ensure every section reflects your voice and strategic choices—not a one-size-fits-all template requiring hours of editing.

Draft 2,000+ words of quality figure descriptions in minutes instead of hours. Systematically analyze office actions and prior art without re-reading documents multiple times. The tool gives you "reading superpowers"—it can search, summarize, and extract information from lengthy documents in seconds, dramatically reducing the repetitive analysis that consumes so much of your time.

Three key differences: (1) Built by patent attorneys who use it daily, not software developers—you can feel this in the subtle details. (2) True flexibility—it's a sandbox you shape however you want, not a rigid workflow someone else designed. (3) Honest pricing—one token pool for everything, no constant upsells, about half the cost of competitors. We respect that you know your practice better than we do.

Absolutely not. The tool drafts individual sections rather than complete specifications, so you review and approve each piece. Don't like the first output? Just tell it what to change in plain language—make it longer, focus on different aspects, adjust the tone. The conversational interface lets you refine iteratively until it's exactly what you want.

Yes! Custom prompts let you encode any repetitive task specific to your practice—checking for problematic language, generating specific types of claim variations, responding to particular rejection types, or anything else you do regularly. You can even share these prompts with your team to standardize best practices across your firm.

Yes, but it's worth it. We prioritize flexibility and control over simplicity, so there's some upfront investment in learning the tool. However, practitioners who take the time to master it produce significantly better work product than they could with simpler, more automated alternatives. Think of it as learning to drive a high-performance vehicle—more effort initially, but far more capability once you know what you're doing.
