What is Sigil

Sigil is a productivity system that makes your growth visible. Track real skills, build habits, manage projects — all with an AI mentor that handles the overhead so you can focus on doing the work.

The mission

Make self-improvement feel as rewarding as it should — by making progress visible.

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. Watching your skills level up feels like achievement. We're building the system that bridges that gap — AI handles the complexity, and every task you complete feeds into visible, meaningful progress.

What makes Sigil different

Four core differentiators that set Sigil apart.

01

AI manages the system. You do the work.

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.

02

Real skill tracking, not surface-level streaks.

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

03

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.

04

Built for people who want to see their growth.

Most productivity tools show you what you haven't done. Sigil shows you what you've built. Your skills have levels. Your attributes grow. New features unlock as you progress. It turns the invisible work of self-improvement into something you can actually see.

The founder

Charles Frank — Founder & Solo Engineer

I spent years trying to be productive — GTD systems, PARA frameworks, habit trackers that worked for two weeks before I abandoned them. None of them showed me what I was actually building. Then I noticed something in the progression fantasy novels I was reading: characters grind real effort and get visible growth in return. I kept thinking: “Why can't real productivity feel like that?” That inspiration became Sigil.

I'm a senior at NYU's Gallatin School of Individualized Study, where I designed a major called “Modern Magic” — Computer Science, Creative Writing, and the history of magical belief systems. Gallatin has no set courseload or traditional milestones, which makes progress feel invisible. That's exactly the problem Sigil solves.

I write all of Sigil's code solo — full-stack TypeScript with Next.js 15, Node.js/Express, MongoDB, and a multi-agent AI system on GPT-4o. Currently running the NYU beta pilot and applying to Y Combinator Spring 2026.
