A framework for building
AI products.
Built by a product designer with a decade of experience. One framework, multiple products — each solving a real problem that only AI can address.
Products
Claudel
LiveClaude Code runs in a terminal. You can't orchestrate multiple agents or see what they're doing.
A desktop GUI that runs dozens of Claude agents in parallel, with Gantt charts and DAG visualization to track every task.
- Parallel agent execution
- Gantt chart task view
- DAG dependency graph
- Real-time streaming logs
Unask
LiveUser interviews take weeks to schedule and cost thousands. Most startups skip validation entirely.
AI personas that interview like real users. Run a simulated mom-test in minutes, not weeks.
- 15+ AI persona templates
- Realistic multi-turn interviews
- Insight extraction & scoring
- Export to PRD format
LocalPDF
LiveOnline PDF tools upload your files to someone else's server.
Merge, split, and compress PDFs entirely in your browser. Nothing leaves your machine.

Tether
In DevDetects when Figma, Notion, GitHub, and Linear drift out of sync — and shows you where.
CarQuick
PlanningPlug in an OBD2 dongle, get a plain-language diagnosis with repair cost estimates.
Design Forge
In DevCLI that searches 62 design systems and generates component code for your stack.
Philosophy
AI is the architecture, not a feature.
The framework only produces products where AI is the core, not an add-on. Claudel can't exist without agent orchestration. Unask can't exist without AI personas. If it could be built without AI, it doesn't belong here.
Shared infrastructure, independent products.
Every product in the framework shares the same tooling, deployment pipeline, and design system. This is what makes it possible to run multiple products with one person — the framework handles the repetitive parts so each product can focus on its unique problem.
Ship fast, learn faster.
Products go from idea to live in weeks. The framework is optimized for speed — launch early, measure what matters, and shut things down if nobody uses them.
About
11 years designing products at Kakao, LINE, NAVER, and fintech startups in Seoul. Led design teams, built design systems, and simplified complex services for millions of users.
In 2025, I started building AI products directly — applying the same design thinking, now with code. BESSL Framework is how one designer ships multiple products solo.
