Launching Our New Developer Portal for Document Comparisons

Listening to Lawyers: The Demand That Launched Super Comparer

We didn't wake up one day with a brilliant idea to revolutionize document comparison. Instead, we listened. Sophisticated transactional lawyers kept coming to us with the same frustration: they needed to compare multiple documents at once, but no tool in the market could do it accurately.

The need was crystal clear. These attorneys wanted to see many documents side by side, even when those documents didn't start from the same template. They needed to understand what might be marked up in a negotiation by viewing multiple versions simultaneously. They wanted documents lined up on a timeline to gauge changes and respond appropriately. For lawyers doing due diligence, the pain was particularly acute. They'd encounter entire portfolios of assets and documents that were supposed to be on the same terms, but they still had to review them one by one to spot differences that might pose risks or affect their deals.

Building the Unprecedented

In 2022, we set out to build document comparison technology that went beyond conventional one-to-one comparisons. We recognized this was uncharted territory - no one in the legal tech market had successfully accomplished multi-document comparison before.

Initially, our focus was straightforward: enable lawyers to compare many documents side by side, regardless of their original templates. We spent considerable effort ensuring our tools could produce accurate comparisons across multiple documents simultaneously.

As lawyers began using our technology, the tool evolved based on their needs and feedback. While transactional M&A lawyers were the primary beneficiaries initially, we recognized that multi-document comparison could benefit every type of lawyer.

When we launched www.supercomparer.com in August 2025, we made it simple for anyone to get started - just sign up for free and immediately begin using the tool.

Unexpected Tech Partner Demand

What we didn't anticipate when we launched was the incredible demand from vendor partners who wanted API access to integrate our technology into their own tools. These partners fell into three distinct categories:

• First, those who wanted a streamlined way to produce accurate, conventional one-to-one comparisons as Word documents. They simply wanted to upload two files and get back a clean blackline output.

• Second, vendors who needed to upload many files and receive structured output - sometimes in JSON format. They wanted to analyze this data to assess changes among groups of similar provisions and text across multiple documents. Often, these results would be fed into large language models for more focused analysis than would be possible with entire large documents.

• Third, vendors who wanted to embed our front-end UI directly into their platforms, so their users could benefit from seeing multiple documents side by side or multiple versions in a timeline view.

This unexpected demand validated our approach: there was significant unmet need in the market, and this need would only continue growing.

We Are Betting on AI's Future

About 18 months ago, we made a crucial bet about how AI would develop. As language models continue advancing, we believed they would follow a pattern similar to humans. As the saying goes, "God created man in His own image", man would create AI in their image. We expect to end up with these fuzzy thinking machines that are probabilistic and excellent at conceptually linking ideas in compelling ways, but not capable of accurately parsing the nuances of text that matter in legal documents (or, at least, they can't do it cheaply and reliably).

We built an engine that could parse document content - the text and strings - separately from the formatting of those strings. This allows us to feed machines structured chunks of text independently from the formatting elements that humans care about: bold, italics, underlining, and so on.

Our architectural choice shows up in how we display information to lawyers. We strip away the noise of formatting and show lawyers the substance. It was a deliberate design decision based on a simple truth: People don't lose lawsuits because they forgot to italicize a word, but they do lose lawsuits because they forgot to capitalize a word, add a comma, or insert a space.

We focus on presenting lawyers with changes that matter across many documents, while preserving formatting for final outputs that users can download from our tool. This approach allowed us to create a system that integrates seamlessly with generative AI. It was our bet that generative AI is here to stay, and we wanted our tool to become an enabler of better AI outcomes and better human outcomes - helping people and machines spot the differences that actually matter.

Listening to Tech Partners: Launching Our Developer Platform

The incredible interest from the legal tech vendor community led us to formally launch a developer page on our website. It will provide comprehensive information about how tech partners and customers can interact with the data our platform provides, including detailed API documentation and technical information about our technology.

We're excited to continue partnering with innovative companies in legal tech and look forward to finding new ways of delivering value - whether directly to lawyers subscribing to our product or through our growing network of vendor partners using our API to enhance their own offerings.

The future of work requires collaborations and deep integrations. We're excited to be part of that transformation.
