# Save and Reuse AI Prompts in the Library
A prompt is the message you type to an AI. The Prompts view in the Kortex Library is where you write the prompts you use again and keep them tidy. You can add blanks to fill in each time, and see earlier versions of a prompt.
## Why keep prompts here?
- Write a good prompt once and use it again, like a recipe card.
- Leave blanks to fill in each time, so one prompt fits many jobs.
To use a prompt in a chat box, see [Prompts everywhere](/docs/prompts-everywhere). The dashboard's Prompts page shows this same list.
## How to write a prompt
1. Click **Prompts** in the Library's left column.
1. Click **New prompt**.
1. Give it a title and type the prompt.
1. If you like, add a **Shortcut** (the word you type after `;` in a chat box), a folder and tags.
1. Save it. Click the star to make it a favourite.
You can also click **Save as a prompt** beside one of your own questions in the reader.
## Blanks and choices
A blank is a gap you fill in each time you use the prompt. You write it between double curly brackets.
- `{{audience}}` is a blank you fill in each time.
- `{{audience=my team}}` is a blank with its usual answer filled in.
- `{{tone:formal|friendly}}` is a choice. The first one is the default.
- `{{selection}}`, `{{clipboard}}`, `{{date}}`, `{{time}}`, `{{page}}` and `{{url}}` are filled in by Kortex.
- `{{>sum}}` brings in another saved prompt's text, by its shortcut.
- A line with only `>>>` splits the prompt into steps.
You do not have to remember these. In the editor, the blank menu adds a blank, a choice, the selection, the clipboard, the date, the page or address, another saved prompt, or a next step. If you select words, the editor offers to turn them into a blank. It flags likely mistakes, such as a blank spelled two ways, but never stops you saving.
When you use a prompt with blanks, a small form opens above the chat box, filled with your last answers.
## Versions
When you edit a prompt's title or text, Kortex keeps the old one. Open a prompt to see **Earlier versions**. Click **Changes** to see what changed, or **Restore** to go back. This computer keeps the last 10 versions of each prompt.
## Starter ideas
Not sure what to write? Open the Prompts view's ⋯ menu and choose **Starter ideas**. Click **Add to my prompts** on one to copy it into your own.
## The Prompts view menu
The ⋯ beside **New prompt** makes a folder, imports prompts, exports them all as a file or as Agent Skills, and opens **Starter ideas** and **Recently deleted**.
## A prompt's ⋯ menu
Each prompt has its own ⋯ menu.
- **Start chat with this prompt…** opens a new chat on the AI you pick, with the prompt already in its chat box.
- **Copy** copies the prompt.
- **Improve with an AI…** asks which site to use. It opens a new chat there that asks the AI to improve the prompt and keep its blanks. You paste the answer back yourself.
- **Edit**, **Add to favorites** and **Duplicate** do what they say.
- **Export as an Agent Skill** saves the prompt as a skill file for tools that read them.
- **Delete…** deletes it.
## Recently deleted
A deleted prompt stays in **Recently deleted** for 30 days. Open it to read it, then click **Restore**. Or click **Delete for good**.
## Folders and tags
Choose **New folder…** in the view's ⋯ menu to make a prompt folder. Use the menus above the list to narrow prompts by folder, by tag, or to favourites only.
## The free plan's limit
The free plan holds 10 prompts and 5 prompt folders. When you go past that, Kortex says so and offers **Upgrade**. Nothing you saved is lost. Kortex Pro has no limit. See [pricing](https://www.kortex-notebooklm.com/#pricing).
:::tip Good to know
- Versions, Recently deleted and your use history stay on this computer.
- **Import prompts…** reads a Kortex export, a JSON list, or a CSV with a prompt column. Prompts with the same text are skipped.
