Communication preferences builder →
Create instructions without taking a personality test.
Build custom AI instructions from your preferred tone, detail, feedback and format. No personality test or signup. Edit and export locally.
Make your AI easier to work with.

All eight tools process your input in your browser. No API key, model credits, or account required.

Start with the job you need done
Starting from scratch? Use the preferences builder. Already have instructions? Run the checker, then compare real responses in the test bench. A neat prompt is a starting point; actual usefulness depends on the model, task, and your judgment.
Explore more instruction tools
The original custom instructions generator and CLAUDE.md generator are still available, alongside the 43-file tuning library.
Use the tools with an agent or your own app
Read the machine-readable catalog and local JavaScript API documentation. The MCP endpoint at https://agent-tune.com/mcp exposes the catalog through get_free_tools; processing functions can be downloaded and run locally. Connecting an agent never installs instructions automatically.
Free means you can use the whole tool
There is no account wall or paid export. The test bench uses answers you provide, so any costs or limits in the AI service where you run a prompt still apply. Tool inputs are not uploaded or stored by AgentTune. Downloads and optional card links contain only what you explicitly choose to export or share.
