About Sigil

What is Sigil

Sigil turns real life into a skill-based progression system. Not a video game — a real-world application of the structure, feedback loops, and visible growth that make RPGs compelling.

The idea came from a simple frustration: productivity tools require you to administrate the system. Tag this. Prioritize that. Reorganize when your categories break down. You spend more time managing the tool than doing the work.

Sigil inverts that. An AI agent named George manages the complexity. You just play the game. Tell George what you need to do, and he creates tasks, schedules them, and awards XP when you follow through. Your skills level up. Your attributes grow. Your character sheet becomes a real record of what you've built.

The mission

Make self-improvement feel as compelling as a game — without turning it into one.

Sigil exists because the gap between “knowing what to do” and “doing it consistently” isn't a planning problem. It's a motivation problem. Checklists feel like obligations. Character progression feels like achievement. We're building the system that bridges that gap with AI-managed complexity and RPG-grade feedback loops.

Why I built this

I'm Charles Frank, a senior at NYU's Gallatin School of Individualized Study. I've spent years trying to be productive — GTD systems in Notion, PARA frameworks, habit trackers that worked for two weeks before I abandoned them. The pattern was always the same: I'd build the system, maintain it for a month, then spend more time reorganizing than actually doing work.

Meanwhile, I was reading progression fantasy novels — the kind where characters grind real effort into visible power. Cradle. Solo Leveling. He Who Fights With Monsters. And I kept thinking: “Why can't real life feel this rewarding? Why does checking off a task feel like nothing, when leveling up a skill feels like everything?”

That question became Sigil.

My Gallatin major is called “Modern Magic” — a self-designed concentration combining Computer Science, Creative Writing, and the history and philosophy of magical belief systems. Gallatin's individualized structure means there's no set courseload, no traditional milestones. It's hard to measure progress when your major is custom-built. That invisible progress problem is exactly what Sigil solves.

I've worked as a Web3 intern at Wildcard Alliance (startup strike teams, AI tools research) and currently intern at Sizzle-Reel building an agentic microdrama script analyzer.

I write all the code for Sigil. Full-stack TypeScript — Next.js 15 frontend, Node.js/Express backend, MongoDB, a multi-agent AI system on GPT-4o, and shared Zod validation schemas. I use AI coding tools (Claude Code, Cursor, Copilot) to move fast, but I design the architecture and review every line. For me, coding is spellcasting — write the right sequence and something impossible appears on screen.

What makes Sigil different

Four core differentiators that set Sigil apart.

AI manages the system. You play the game.

Most productivity apps add overhead. Sigil removes it. George handles task creation, scheduling, skill matching, and progress tracking. You talk naturally — ‘remind me to submit my assignment Thursday’ — and George turns it into a structured plan with XP rewards.

Real RPG mechanics, not surface-level points.

This isn't a habit tracker with a points badge. Sigil has named skills that level up (Fiction Writing: Level 12), attributes that grow as skills compound (Focus: 34, Discipline: 41), a character sheet that reflects real work, and an unlock system where new features are earned through progression.

Progressive disclosure prevents overwhelm.

On day one, you get tasks, skills, attributes, and George. That's it. When you hit Level 2, habits unlock. Level up more, and you earn projects, calendars, sprints. Sigil grows with you instead of drowning you in features.

Built for the LitRPG generation.

Millions of people read progression fantasy and want to live it. They don't want a to-do list with a streak counter. They want a character sheet. Skill trees. Attributes. Level-up ceremonies. Sigil is the first productivity system built for this audience.
