The engineering, in public.

Chorusse's practice work is advising firms on AI and client data. This is the other half: tools we build in the open, free, with the source readable by anyone. It exists partly because it's the work we like, and partly because it's the only honest way to show what we understand about these systems.

Why this is on the site at all

You can't audit our judgement. You can read our work.

If you're deciding whether to let someone near your firm's client-data questions, credentials only tell you so much. What's harder to fake is a body of work that's public, specific, and candid about where it falls short — including a tool of ours that measures itself against a competitor and reports when it added nothing.

What's here

Two tools and a comparison.

The comparison

We published a head-to-head against our own competitor.

Including a section on where the competitor is genuinely better than us. The empirical half is pre-registered and hasn't been run yet — and rather than invent numbers, we say so. A tool whose whole point is admitting when it didn't help cannot fabricate its own benchmark.
