Stop promptsplaining

Vostra lets you build reusable, shareable instruction sets for LLMs - tone, brand voice, length, output format - and sync them across your team. Never start a conversation with AI from scratch again.

Meet the instruction layer

LLM output is only as good as the input - and most teams are still making it up as they go. Instruction sets turn messy prompts into reusable building blocks that work across tools, teammates, and tasks.

Modular Contexts

Build a system of reusable blocks that capture how your team speaks, writes, and thinks.
