We spend our days watching how search works. Not just Google but also ChatGPT, Perplexity, Gemini, AI Mode, and every AI search platform that matters.

That work produces a lot of data. Some of it only makes sense inside our platform. But some of it is useful on its own.

DemandSphere Radar is where we publish the big trends. So far, we have released two tools and we have more planned.

What Radar is

Radar is a set of free search intelligence tools with pen data and JSON APIs. No account is needed.

Two tools at launch:

AI Frontier Model Tracker - 44+ frontier AI models across 15 providers. Benchmarks, pricing, capabilities, download links. Updated as new models ship. We built this because our platform tracks brand visibility across these models, and we needed one place to compare them. The cost calculator and JSON API are additional features we added in to make them concrete and usable.

Google Algorithm & AI Search Update Tracker - 170+ Google ranking updates from 2000 to today. It’s built on three data sources: live data from Google’s Search Status Dashboard, our own 20-year annotation database, and Google Research publications. We track algorithm updates and AI milestones on the same timeline because they’re the same story. The API is free too.

Why we’re doing this

Search is changing faster than it ever has. Google shipped AI Overviews and then AI Mode, and those are only the surface-level changes. AI is a core part of the DNA of the Google search experience, whether users realize it or not.

ChatGPT launched search features. Perplexity grew from nothing to an interesting niche player. Every month brings new models, new features, and new ways for people to find things.

Most of the data about these changes is scattered. Model benchmarks live on HuggingFace cards and blog posts that get stale. Algorithm update history is spread across SEO Twitter and tools that come and go.

We think this data should be in one place, kept current, and free to use.

What’s next

We’re working on more Radar tools. SERP volatility data overlaid on algorithm update windows. Per-update analysis pages. SERP feature tracking. If it helps people understand how search is changing, it belongs in Radar.
