Hello friend, I made a GPT who can help you with this, feel free to probe it for infos i dont mind!

I fed it your question

Remember, 20 md files max, leave room for any lore you want to integrate. if you’re following a story like reborn as a space merc remember knowledgebase files cant read images only ocr text. MD files with solid structure, metadata, update times, contained files for contained systems!

ChatGPT can do really dang well.

Welcome, traveler of the stars! You’re asking exactly the right questions to begin your galactic journey—and you’re in luck, because the system we’ve built for our Sci-Fi World is the perfect example of how to create your own AI-powered campaign universe.

Let me guide you through how to build something just like our futuristic space-based RPG system using a Custom GPT, broken down step-by-step with answers to your questions and a full teaching path.

:star: 1. Can a Custom GPT use PDFs and web info to generate content?

Yes, absolutely! A Custom GPT can process uploaded PDFs, markdowns, and even scrape/ingest structured data from websites.

For example, our system includes files like world_scifi.md, which holds an entire modular universe, with directories like:

  • character_creation.md (backgrounds, origins)
  • space_technology.md (ship systems, weapons, defense)
  • faction_relations.md (political dynamics)
  • navigation_systems.md, planetary_systems.md, etc.
    All of this was uploaded and parsed by the GPT for consistent use across gameplay.

:white_check_mark: What You Can Do:

  • Use GPT-4 or ChatGPT with file upload to ingest your rules and lore.
  • Organize your documents like we did: world overview, systems, factions, characters.
  • Keep each file focused (e.g., “ship systems,” “psychic abilities”) for clarity.

:inbox_tray: 2. Best Way to Upload and Integrate Rules, Lore, Mechanics?

Use Markdown or clean PDFs with clear headers. We recommend:

  • ## Section Headers to separate systems
  • Bullets for itemized mechanics
  • JSON snippets if you’re defining things like NPC templates

Organize your content like so:

01_world_overview.md
02_core_systems.md
03_character_creation.md
04_space_technology.md
...

Once uploaded, a GPT (like ChatRPG or your own) can reference, quote, and create new ideas that obey your rules.

:compass: 3. How to Make the AI Stay Consistent with the Game World?

This is key. Here’s what we do:

  • Core Lore Files are always referenced during generation (e.g., we treat world_scifi.md as the law).
  • Core Mechanics Files like system_skills.md, system_combat.md, system_relations.md define how gameplay works.
  • Memory System stores critical details across sessions—who your allies are, what tech you’ve discovered, your criminal history, etc.

You can teach your Custom GPT:

  • “Only generate characters that follow X race and Y tech levels.”
  • “Ensure dialogue reflects Z political factions.”
  • “When generating planets, refer to the planetary_systems.md entries.”

:toolbox: 4. Easiest Way to Build for Non-Coders?

Here’s the zero-code recipe:

  1. Use ChatGPT (Pro) → Create a Custom GPT with:
    • Your tone and behavior rules
    • Your uploaded game files
  2. Use “Custom GPT Instructions” to tell it:

    “Use my uploaded markdown PDFs to create content consistent with my Sci-Fi campaign. Always obey game rules from files like system_combat.md and space_technology.md.”

  3. Ask ChatGPT to:
    • Generate NPCs
    • Expand lore for a new planet
    • Simulate missions or faction dynamics

Optional: Add tools like DALL·E (for art) and Python (for dice rolls or crafting) to automate generation.

:money_with_wings: 5. Budget-Friendly Tips

  • Use ChatGPT Plus ($20/month) – supports Custom GPTs and file upload.
  • Don’t pay extra for devs unless you’re expanding to a full web app.
  • Build once, re-use often: one good world file powers 100 adventures.
  • Use Markdown editors (Obsidian, Typora, etc.) for writing your lore.

:brain: Bonus: Learn from Our Sci-Fi World Template

We built our world with:

  • Rich systems: psychic abilities, alien species, ship AI companions
  • Tactical modules: boarding mechanics, economic zones, black-market trading
  • Evolution mechanics: political power shifts, tech trees, faction memory
  • Modular design: each component can be swapped or extended easily

Would you like a starter kit version of this world as a downloadable template to build from?

Or would you like help designing your own unique setting, using The Architect’s world builder system?

Let me know and I’ll walk you through it—one question at a time :milky_way:
