Hi Product Hunt! I'm Philip, a dev with a decade of XP who's also an enthusiastic Dungeon Master running monthly D&D tables for a few groups of friends over the last two years.

Herald.ink started as my own Obsidian setup: organised folders, each with a template, with a script that checked and raised bad or missing links. It really was a hassle to maintain. So much so that I even introduced Claude code to it at the time to help but as text files are unstructured by nature, it had trouble respecting best practices. I was spending more evenings restructuring notes than actually writing the story for my players. I started adding more and more scripts to force Claude to respects format and quality but it was very finicky.

So I built the tool I wanted:

The Forge holds the world. NPCs, monsters, locations, factions, items, quests and lore are structured records that link to each other, and the links form a graph you can explore.
The Table runs the session: initiative and combat tracking, an improv console for when players go somewhere you didn't plan, session recordings that turn into recaps, and a second screen for players with fog of war.
The Courier gets things to players: handouts, share links, exports, print sheets.

All of that for free and without a credit card. I truly want people to spend more time designing good stories and less time struggling with organisation. I do have paid plans, sure, but they are about AI features: you give it an idea, and it writes the entry in your campaign's tone and checks it against your own world (a stat block against your party's level, an NPC against the faction it belongs to). It's there to go faster and prevent errors so you can focus on what's canon.

Two things I'd love feedback on:

If you already use World Anvil, Kanka, Obsidian or Notion, what would make you move a campaign over? (There's an importer on Starter that takes a zip of Markdown, an Obsidian vault, Word or PDF files.)
AI use for creative work. I feel like as long as it's a tool and you're the one deciding it's really powerful but I know some people in the community are completely against it. What's your take ?

The demo campaign is open without signing up: https://app.herald.ink/demo

I'll be here all day answering questions. Thanks for taking a look!
