Pro Features: Custom Prompts and Branding

How to use the custom prompt editor and PDF branding settings available on the Hoshimichibiki plan.

The Hoshimichibiki plan (7,980 yen/month) gives you full control over how AI reports are written and how they look when exported as PDFs. These features are designed for professional astrologers and practitioners who want to deliver reports under their own brand and in their own voice.

Custom prompts and branding are available on the Hoshimichibiki plan only.

Custom Prompts

A custom prompt defines the writing style, tone, and structure that the AI uses when generating reports. Instead of relying on preset styles, you can specify exactly how you want the AI to write - from persona to phrasing to the depth of each section.

What You Can Configure

  • Persona (the astrologer voice the AI writes as)
  • Writing style and tone (formal, conversational, poetic, etc.)
  • Expression preferences (use of metaphor, sentence length, vocabulary level)
  • Handling of technical terminology (use astrological terms directly or explain them plainly)
  • Section-by-section instructions (11 natal sections configurable individually, including Sun, Moon, Ascendant, and more)

Creating a Custom Prompt

  1. Open Settings - Report Settings tab in the app
  2. In the Custom Prompts section, tap Create New
  3. Fill in the prompt fields and save
  4. The first prompt you create is automatically set as your default

Forking from a Preset

You can use an existing style preset as a starting point and customize it.

  1. In the prompt selector, tap Fork on a preset
  2. Edit the fields as needed and save

Forked prompts are saved as custom prompts and can be edited freely.

Setting a Default Prompt

The default prompt is used automatically when generating reports. To change the default, tap Set as Default on any prompt in your custom prompts list.

Branding

Branding settings let you add your own logo text and subtitle to PDF reports. This allows you to issue reports under your practice name or service brand.

What You Can Set

  • Logo text: Your brand name shown in the PDF header (e.g., "Stellar Garden Astrology Studio")
  • Subtext: A subtitle displayed below the logo text (e.g., "Personal Birth Chart Reading")

How to Configure Branding

  1. Open Settings - Report Settings tab in the app
  2. In the Branding section, enter your logo text and subtext
  3. Tap Save

The branding will appear on all PDFs generated after saving.
