Recall 91.5, F1 93.3

I’m Henry, cofounder and CTO at Span (https://span.app/). Today we’re launching AI Code Detector, an AI code detection tool you can try in your browser.

The explosion of AI generated code has created some weird problems for engineering orgs. Tools like Cursor and Copilot are used by virtually every org on the planet – but each codegen tool has its own idiosyncratic way of reporting usage. Some don’t report usage at all.

Our view is that token spend will start competing with payroll spend as AI becomes more deeply ingrained in how we build software, so understanding how to drive proficiency, improve ROI, and allocate resources relating to AI tools will become at least as important as parallel processes on the talent side.

Getting true visibility into AI-generated code is incredibly difficult. And yet it’s the number one thing customers ask us for.

So we built a new approach from the ground up.

Our AI Code Detector is powered by span-detect-1, a state-of-the-art model trained on millions of AI- and human-written code samples. It detects AI-generated code with 95% accuracy, and ties it to specific lines shipped into production. Within the Span platform, it’ll give teams a clear view into AI’s real impact on velocity, quality, and ROI.

It does have some limitations. Most notably, it only works for TypeScript and Python code. We are adding support for more languages: Java, Ruby, and C# are next. Its accuracy is around 95% today, and we’re working on improving that, too.

If you’d like to take it for a spin, you can run a code snippet here (https://code-detector.ai/) and get results in about five seconds. We also have a more narrative-driven microsite (https://www.span.app/detector) that my marketing team says I have to share.

Would love your thoughts, both on the tool itself and your own experiences. I’ll be hanging out in the comments to answer questions, too.

This article was written before Opendoor and before a record breaking $10B was pumped into proptech in 2018.

The consensus now is that this industry is undergoing rapid change. At the bottom end of the market (maybe 10%), iBuyers like Opendoor will likely completely disrupt the traditional brokerage model. Next, you will see discount brokerages (Redfin, Purplebricks, et al) take more and more of the market. Full commission brokerages will still be the mainstream for the foreseeable future, but commissions will come down modestly, even for them.

As purchasing or selling a home is one of the most expensive, most emotional, and most intimidating transactions you will ever do, seeking the help of a real estate agent is generally a good idea. Increasing competition will create more options and more value for consumers than we've ever seen before and that's a good thing.
