Osbias - Cognitive Journal

Osbias is a text editor that combines structured thinking frameworks with AI-powered assistance to help users become better thinkers. It bridges personal knowledge management and reasoning templates, with a sophisticated journal editor, AI chat, goal tracking, and publishing capabilities.

I built the entire product from roadmap to deployment, including 15+ API endpoints with Swagger documentation.

CodeMirror-based journal editor with framework-guided writing and keyboard shortcuts

AI chat integration for cognitive assistance, bias checking, idea validation, and paraphrasing

Thinking frameworks like First Principles and OODA Loop that users can create and apply

Goal management with actionable items and progress tracking

Publishing to a public feed or to a personal API endpoint

Export in multiple formats (txt, md, zip)

Template systems for consistent thinking patterns

User authentication and admin panels with RBAC, rate limiting, and hashing

Light and dark-themed UI with responsive design

15+ API endpoints with full Swagger documentation

SQLite database with proper migrations and production-ready infrastructure

Product definition: This was a 0-to-1 product with no existing spec. I defined the feature set, created the roadmap, and organized the development workflow from scratch.

Complex state management: The editor, AI chat, frameworks, and goal tracking all needed to share state cleanly. I used Redux with advanced React hooks to keep things predictable across the app.

Scalable architecture: Built the Next.js backend with modular API routes and SSR where it improved performance. The 15+ endpoints are documented with Swagger so the API is self-describing.

Deployment: Set up a Docker-based deployment pipeline on a VPS with proper migrations and production configuration.
