Voice and tone

Tone sets the emotional temperature of a course. Coassemble offers three: Informal & Conversational, Academic & Research-Based, and Motivational & Persuasive.

Choosing a tone is a learning design decision: it signals how learners should engage with the material and shapes the whole experience. When you generate or refine a course with AI, you pick one of three tones. Here's how to choose.

The three tones

Informal & Conversational

Approachable and human, this tone creates psychological safety and reduces friction in learning. Best for personal development, creative topics, general interest courses, or lighter workplace content.

Academic & Research-Based

Precise, structured, and authoritative. Use it when learners expect depth, rigour, or evidence, such as scientific, technical, or compliance-heavy topics. A good fit for something like cybersecurity training, where accuracy and clear procedures matter.

Motivational & Persuasive

Energetic and confidence-building, this tone creates momentum and inspires action. Ideal for self-improvement or leadership courses, like a professional development course on stepping into management.

How to choose

Match your tone to both your content and your learners. Think about their goals, their context, and what will keep them engaged. The right tone makes the same information land very differently.

Frequently asked questions

Where do I set the tone?

You choose a tone when you generate a course with AI, and you can also change the tone of existing text using the Refine options while editing.

What's the difference between tone and brand voice?

Tone is the feel you pick for a specific course. Brand voice is a saved, workspace-level setting that shapes how AI writes across all your courses, including traits, perspective, and vocabulary.

Can I change the tone after generating?

Yes. Highlight text while editing and use Refine to change its tone whenever you like.
