Generic AI copy is easy; on-brand copy is hard. Copylume keeps suggestions aligned with your voice using templates and constraints.
Templates
Templates define the kind of copy. For example:
- hero_title — Short, punchy headline (e.g. 6–10 words).
- hero_subtitle — Supporting line that builds trust or clarity.
- hero_cta — Call-to-action button or link text (e.g. 2–4 words).
Each template can have default min/max length and style hints. When you call the API or use the widget, you pass template so the model knows what to generate.
Constraints
Constraints tighten the output per request or per field:
- minWords / maxWords — Keep length in check (e.g. hero title 6–10 words).
- bannedWords — Words that must not appear (e.g. “cheap”, “discount”).
- styleGuidelines — Short instructions (e.g. “Avoid absolute claims.” or “Use a friendly, casual tone.”).
You can set defaults in your API or dashboard and override per field when embedding the widget.
Why it matters
Without templates and constraints, you get one-off copy that might be fine once but drifts over time. With them, every suggestion stays within the guardrails you set — so you can ship faster without losing brand consistency.
