Larsen Code Labs, Inc.

Software that keeps hard conversations at work from getting harder.

We build small, sharp tools for workplace communication. Our first product, Tonalyzer, reads the tone of a message before you send it — so the point lands the way you meant it to.

What we build

Eight detectors, three families, one goal: fewer messages you regret sending.

Tonalyzer reads a draft the way a sharp, candid colleague would — before it goes to Slack or your inbox.

  • Condescension
  • Performative Bluntness
  • Microaggression

The company

A small, remote-first studio, built to ship one thing well before it ships the next.

Larsen Code Labs, Inc. is an Arizona C Corporation. We're a micro-SaaS company — deliberately small, fully remote, and focused on tools we'd want to use ourselves.

Tonalyzer is our flagship product and current focus, now in its polishing phase ahead of release.
