Misc tools

Building tools and environments for close friends who build games.

Project 01

BRAGI

An AI-first recording studio: the artist plays, the AI does the engineering.

When I started to play music, I ran into the problem of choosing which DAW to use: FL Studio, Ableton, Logic Pro, etc. None of which I actually like, so I built my own one, running locally on my PC. So instead of watching hours of explainer videos, I use that time to build, and to get exactly what I need and want.

What it does

  • Recording sound & video

    Plug in whatever instrument and record it easily together with video. No separate editing tools needed anymore.

  • Editing & mixing

    My own instruments, sound and effect library inside the app, so I can add and edit tracks easily without relying on stupid subscriptions or paywalls.

  • Visualisation

    Since I want to build bridges between sound and visuals, I built in my own visualiser that turns notes into geometry. It’s all just math, after all.

Project 02

dnd13

The Dragon’s Lantern: a D&D app for players and Dungeon Masters.

Visit dnd13.com

Helping a family member build a D&D app: a fun and exciting project that gives players a companion app to use across their D&D games.

  • MCP server

    dnd5e

    6 tools

    Spells, monsters, classes and rules from the D&D 5e reference, plus a dice roller, so Claude looks things up instead of remembering them wrong.

  • Skills

    SDK & figures

    2 skills

    How to build a new tool on the app’s own SDK, and how the creatures on the living map are made: real 3D models drawn live, never scripted shapes.

  • MCP server

    Blender

    Hooked into the 3D pipeline, so the agent can open, fit and render the figure builder’s bodies, clothes and armour in Blender.

What it does

  • Your hero

    A character screen with a portrait, gear dragged into its slots, spells and inventory, saved to your account.

  • 3D figure builder

    Shape a miniature of your character: species, body, face, clothes, armour, weapons and pose. Use it as a portrait or a token on the map.

  • Games & chat

    Start a game, invite your party, bring a hero, and talk in party and private chats that run on Nostr.

  • The DM’s screen

    Up to nine tools side by side: battle tracker, maps, NPCs, session notes, spell tracker. All in sync with their full pages.
