Tonalyzer
An AI-powered tone coach for workplace communication. Tonalyzer reads a message before you send it and flags exactly what's likely to land wrong — inside Slack and directly in your browser.
Eight detectors, organized into three families.
Every draft is checked against detectors grouped by what kind of problem they catch — friction between people, unclear asks, and mismatched confidence.
Interpersonal Friction
Passive-Aggression
Catches wording that reads as pointed or resentful under a polite surface.
Condescension
Flags phrasing that talks down to the reader, intentionally or not.
Performative Bluntness
Identifies "just being direct" framing that's really about optics, not clarity.
Microaggression
Surfaces subtle, often unintentional language that can land as exclusionary.
Clarity
Unclear Ask
Flags messages that don't state what action is actually being requested.
Fake Urgency
Catches artificially inflated time pressure that erodes trust over time.
Calibration
Anxious Over-Qualification
Flags excessive hedging and caveats that undercut a message's confidence.
CYA Hedging
Identifies defensive language written to protect the sender rather than inform the reader.
