Tendoo Design

Voice & Tone

Define how Tendoo communicates with users through a consistent, human, and purposeful voice.

Voice & Tone

Tendoo’s voice is a reflection of our brand personality — clear, helpful, and trustworthy. It’s consistent across all products and platforms, from interface messages to documentation and marketing copy.

Our tone adjusts depending on the situation. We speak differently when onboarding users than when presenting errors or confirming destructive actions — but we never lose our core voice.

Tendoo Voice Principles

  • Clear — Speak plainly. Avoid jargon and technical complexity.
  • Helpful — Provide guidance without overwhelming. Always consider the user’s context.
  • Human — Write like a person. Be warm, respectful, and approachable.
  • Confident — Guide users with purpose. Avoid hesitation, but don’t be arrogant.

Tone by Situation

SituationToneExample
OnboardingFriendly, inviting“Let’s get started — we’ll guide you through.”
Success messagesPositive, brief“All set! Your changes have been saved.”
Error messagesCalm, clear“Something went wrong. Try again or contact support.”
Destructive actionsDirect, cautious“Are you sure you want to delete this item?”
Empty statesEncouraging“No items yet. Start by adding your first one.”
Tooltips & labelsNeutral, helpful“Set how often notifications are sent.”

Voice Don'ts

  • ❌ Don’t use slang, idioms, or sarcasm.
  • ❌ Don’t be robotic or overly technical.
  • ❌ Don’t blame the user in error states.
  • ❌ Don’t use unnecessary exclamation points or filler.

Tips for Writers

  • Use active voice: “Upload your file” instead of “Your file can be uploaded.”
  • Use contractions when appropriate: “You’re signed in” sounds natural.
  • Avoid over-apologizing. Be empathetic, not excessive:
    ✅ “We couldn’t save your changes.”
    🚫 “Sorry! Something broke! We’re really sorry!”

Tendoo’s voice creates trust and connection. By writing with consistency and care, we help users feel confident — every step of the way.
