# From a Topic

Describe what you need and Twistly writes the whole presentation — structure, text, visuals.

## Writing a good topic prompt

A short phrase works ("Q3 marketing results"), but a sentence or two of direction gets noticeably better results. Useful ingredients:

* **Goal** — what should the presentation achieve?
* **Audience** — who is it for? ("for new employees", "for investors")
* **Emphasis** — what must be included or avoided?

> *"Onboarding presentation for new sales hires: our product line, target customers, and the first 30 days. Friendly tone, end with a checklist."*

Keep it focused — the field suggests up to about 450 characters, which is plenty for a well-aimed prompt. There's no need to specify formatting or slide-by-slide structure; the settings below handle that better.

If you paste a large amount of text into the topic field, Twistly switches to **Create from Text** automatically — the right tool for ready-made content.
{% endhint %}

## Settings

* **Language** — 38 languages available. Defaults to **Auto**, which matches your prompt.
* **Number of slides** — see [Number of Slides](/create-a-presentation/number-of-slides.md).
* **Content** — how much text appears on slides: **Short**, **Detailed**, or **Bullet Points**.
* **Tone, presentation type, and audience** — optional menus that steer the writing style.
* **Image source and style** — see [Images in Your Presentation](/create-a-presentation/images.md).

All settings are remembered for next time.
