System Prompt & Document Dividers

Note: the following is for Advanced, Technical users. In user menu -> settings -> Config, you can adjust the system prompt and document dividers. Any adjustments will impact the information sent to the AI model selected when using Tools (and thus the output from the model). 6.1 System Prompt

A system prompt is a hidden set of instructions that Plotdrive slides in before every prompt you send to the language model—think of it as the rulebook the AI must obey. Because it fires on every Tool, a single line here can reshape all output (e.g., “Always write in present tense and refuse spoilers”). Powerful—and risky. We recommend it only for advanced users who understand prompt layering; most writers will get the same control with less friction by creating a normal context document (e.g., “Writing Style & Rules”) and keeping that file toggled ON at the top of the project. That way you can adjust rules per project without rewriting your project's system prompt.

6.2 Document Dividers

Document Dividers let you change how your context docs are labeled when the model reads them. These labels are viewable when using the binoculars button (prompt preview) at the top of your document editor. By default, Plotdrive sends each file with a clear header so the AI knows where one document ends and the next begins. Some very old or lightweight models occasionally blur those boundaries. If you notice the AI mixing two sources—especially when you’re testing smaller third-party models—you can edit the divider string to add stronger cues. For modern GPT-4, Claude, or Gemini models you can safely ignore this setting; use it only if you’re squeezing extra mileage out of limited-context engines.
