Your prompt here.
Model names follow OpenRouter format (provider/model).
Prompt accepts attachments via melding — other glyphs fuse onto it spatially:
| Glyph | Port | Effect |
|---|---|---|
| Doc (▤) | bottom | File sent as multimodal attachment (images as image_url, PDFs as file) |
| Note | bottom | Text included in prompt context |
| AX / SE / PY | right | Chains into prompt (execution pipeline) |
Multiple Doc glyphs stack via doc-to-doc melding above the prompt.
Play button sends POST /api/prompt/direct with the template and any melded file IDs. A Result glyph auto-melds below the prompt with the LLM response.
