I build AI products that thousands of people use every day, and I write about what I learn shipping them.
I am Adi Leviim, a founder and full-stack engineer. I build the AI productivity suite for the four biggest assistant platforms, plus an AI SaaS for landing pages.
I write about the messy reality of building AI products in 2026. The architecture decisions, the user research, the pricing experiments, the things that work and the things that absolutely do not. If you are building with LLMs, shipping SaaS, or just trying to use AI to get more done, you will find something here worth your time.
No hype. No "10x productivity" clickbait. Just honest lessons from shipping AI software that people pay for.
What I'm building
AI Toolbox, formerly ChatGPT Toolbox, is a Chrome extension that adds folders, full-text search, prompt libraries, bulk actions, and export to the AI assistants people use every day. It ships as one install with four modules you toggle on: ChatGPT, Claude, Gemini, and Grok. It is trusted by 40,000+ users across 180+ countries, holds a 4.7 out of 5 rating across 816 Chrome Web Store ratings, carries a Featured badge, and runs in 12 languages including full right-to-left support for Arabic and Hebrew.
It started as a hacky weekend build to fix my own problem: hundreds of unorganized ChatGPT conversations and no way to find anything in them. It is still the product that taught me the most about shipping software people actually keep.
Landy AI is an AI landing page builder that generates pages with conversion-focused copywriting, combining a multi-agent LLM pipeline with proven CRO technique, A/B testing, and drag-and-drop editing. It began the same way, as a problem I kept hitting myself.
What I write about
The gap between AI demos and AI products. I am interested in the design decisions the AI industry made by accident, under deadline, in 2022 and 2023, and has not revisited since.
Most of my essays come out of a single observation: AI chat inherited a messaging-app skeleton and then asked it to do knowledge work. That one decision explains the chat box as a universal interface, the empty state that teaches nothing, the missing undo, the conversation you can never find again, and the message that has no URL. I have written a piece on each, mostly in UX Collective.
The other half is founder engineering:
- Building and scaling AI-powered Chrome extensions, the ones I shipped and the ones I scrapped
- Production LLM architecture, and where the cost actually concentrates
- The unfiltered founder journey: pricing, retention, churn, and the things nobody posts about
- React, Next.js, and frontend architecture for AI products
- Running a global product with users in 150+ countries
The proof
Every article here is informed by what I see inside these products: how thousands of real people actually use AI, what breaks at scale, and what I would do differently if I started over tomorrow.
7+ years as a full-stack engineer. I built SaaS products for US-based tech companies before going founder full time. React, Next.js, Node.js, and the modern AI stack are home turf.
