We named our tool Dativus after the grammatical concept known as the dative case. This choice reflects the specific role we aim to play in the interaction between a user and an AI model.

The Meaning of Dativus

In linguistics, the dative case (from Latin *dativus*) often marks the recipient of an action—the person or thing *for whom* or *to whom* something is given.

We found this a fitting analogy for our tool. Dativus is designed to help structure a user's initial instructions into a clearer prompt, which is then "given to" an AI model for processing. The tool itself functions as an intermediate step in this handover.

How the Name Connects to Function

The core tasks of Dativus align with this idea of preparation and delivery:

  • Structuring Prompts: The tool helps add missing context or structure to a basic idea, preparing it for the AI model.
  • Clarifying Intent: For specialized tasks like image generation, it assists in refining descriptions so the visual output may better match the user's intent.
  • Maintaining Privacy: Operating locally in your browser, Dativus processes your prompts without sending them to our servers, keeping the interaction between you and your chosen AI service.

In Summary

The name Dativus serves as a reminder of our tool's focused purpose: to assist in the preparation and delivery of your instructions to an AI. We see it as a supportive utility, not the main actor, in the creative process.
