About prompster
Prompster adds slash commands to AI chat apps.
Type / and a prompt keyword to instantly insert saved prompts right inside the chat box, without breaking your flow. Prompster brings fast prompt autocomplete to ChatGPT, Gemini, Claude, Grok, and other popular chat apps.
Prompster includes a built-in prompt library out of the box, and you can add your own prompts in a couple of clicks. Create personal shortcuts for recurring tasks, writing styles, code reviews, research prompts, translations, and more.
For more advanced workflows, Prompster also supports prompt variables. Wrap part of a prompt in brackets like [topic] and fill it in when you use the command. It also supports handy dynamic values such as clipboard content and dates.
Features:
- Slash-command prompt insertion directly inside supported chat apps
- Custom prompts and keywords
- Variable placeholders for complex prompt templates
- Configurable trigger character
