The problem with solo RPG notes? They break your flow. You're deep in a scene—dice rolling, oracles answering, tension building—and suddenly you're drowning in scattered notes. Journals get messy. Pure prose buries the mechanics. Bullet points turn cryptic by next week. Lonelog is a lightweight notation system that captures the rhythm of solo play without interrupting it. Five symbols. One language. Action, question, roll, result, consequence—the core notation mirrors how you actually play. Learn it in minutes, use it forever. - Works with everything. Ironsworn. Thousand Year Old Vampire. Mythic GME. Your favorite homebrew. Any system, any oracle, one consistent format. - Scales to your style. Running a quick one-shot? Stick to the basics. Managing a sprawling campaign with dozens of NPCs and tangled plot threads? Layer in progress clocks, location tags, and story trackers as you need them. - Paper or pixels. The notation works equally well in markdown editors and spiral notebooks. Your choice. - Find anything, fast. Consistent tags mean you can locate that crucial NPC detail from twelve sessions ago in seconds. Record what matters. Share what you played. Pick up exactly where you left off. Your solo adventures, finally speaking the same language. This work is released under the Creative Commons Attribution Share-Alike 4.0 License
