Campaign Studio by CharGen

What it does

A writing room for tabletop GMs: campaign notes, session records, worldbuilding and an AI assistant in one place. It drafts, you decide. Nothing lands in your canon until you choose Insert, Replace or Apply. Answers cite your own notes, carry Known, Inferred or Proposed labels, and when the campaign genuinely does not answer something, the assistant says "we do not know" instead of inventing lore. Transparent gold pricing per run, and free accounts can try it.

Write RPG campaign notes and prep with sessions, lore, World Codex and a source-backed Campaign Assistant. Review every suggestion before it becomes canon.

Write campaign notes and prep, organise your world, and ask an Assistant that can show where every answer came from. Campaign Studio is the first-party workbench for the material already inside your campaign. It does not ask you to rebuild the world in a new database. Open the notes and folders you already use, write at full width, mention campaign records, add images and tables, and keep the Assistant beside the page. Leave the caret where the next line belongs or highlight the passage that needs work. Choose one focused action, read the proposal, then decide whether it enters the note. Studio reads the passage around the caret and the campaign facts that matter, then drafts the next beat…from char-gen.com

  Hi HN! I'd love your feedback for this AI storytelling game. Remember when you used to read choose-your-own adventure books as a kid? We're trying to re-create that. The site lets you create adventures by seeding them with parameters that end up feeding LLMs: title, genre, writing style, etc. Once you've done that, you can play your book like a game: with custom chapters, illustrations, voice narration, choices, and dice rolls. We’re really into the idea of merging the open-ended generative AI with goal-directed story arcs that the game author can control. Everything is open source (links…

  Clipto MCP▲655

  Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

  Simple algorithm and color space to generate diverse skin tones▲627

  Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
