Inside A Viral App Builder’s AI Stack — Show me your Stack

Magnus Farza is a prolific solo builder who ships apps and content at remarkable speed by combining analog habits with a deeply integrated AI stack. He doesn’t know Swift but built Clicky—a viral AI cursor companion—entirely with Claude Code in hours. His process starts offline (gym, notebook, coffee shop), moves through a freewriting app he built himself, and then into AI tools that help him prioritize, build, and ship. The episode walks through his daily routine, inspiration system, build workflow, and content machine.

Morning starts analog and intentional
- Doesn’t look at his phone for the first 3 hours after waking up
- Goes to the gym or for a run, carrying a small black-paper notebook to capture ideas in the moment
- Also sits at coffee shops for 10 minutes just observing—calls this “where all the alpha is”
- Checks in with his mom and fiancée first; if they’re good, he’s good
Freewrite app: the bridge between analog and digital
- Built a personal app where he writes nonstop for 15 minutes with no backspace, no thinking
- Uses it every morning to process the raw ideas from his notebook
- Feeds the freewrite entries into Claude, which has full access to his writing history
- Claude searches past chats and entries, synthesizes his raw thoughts, and gives him a new way to think about what he already said
- After this, he identifies his one A+ problem for the day—if he does that one thing, the day is a win
Email script: AI handles the inbox
- Built a script that runs at 6:00 a.m. daily, scanning all emails and tagging them into categories like “attention,” “you” (spam/annoying senders), “AI didn’t know,” and “quick checks”
- He only looks at the “attention” inbox—dramatically reducing email anxiety
- Example: it flagged a tax deadline reminder as “attention” with “3 days left to file my taxes”

Ideas come from everywhere, especially music
- Clicky was born from a song at a red light—he closed his eyes and imagined a buddy following his cursor, like a Pixar character living in your computer
- He parked, went home, and built it that day
- Most original ideas come from songs; he was listening to Porter Robinson’s “Mother” and immediately saved the idea for an Instagram video
Day One journal: 10 years of visual inspiration
- Has used Day One since 2014 as a dumping ground for screenshots, colors, vibes, and things he finds beautiful on the internet
- Collects inspo deliberately—colors from Twitter, Simpsons vibes, cool shots—so he can reference them later
- Now migrating this into Clicky, which can remember things on command and spin up agents to research and file them
Clicky as a living memory system
- Can hold Clicky’s hotkey and say “remember this song” or “remember this person”—it takes a screenshot, spins up an agent, and files it into his personal Wikipedia
- Example: told Clicky to remember someone named Arlan and check on him monthly for potential hiring

Built a Wikipedia for his own life
- Fed an LLM all his iMessages, Apple Notes, and diary entries, ran it through a pipeline, and generated a full Wikipedia with articles on books, companies, cities, and more
- Everything is back-linked—clicking “San Francisco” opens another generated article
- As he adds new content, the system automatically finds the right article and updates it
- Functions like a personal librarian that’s an expert on him, queryable through an agent
- Currently backing up 10 years of Day One inspiration into this system

Clicky was built entirely with Claude Code through prompting
- Started with: “I want to make a desktop app on my Mac where my cursor is followed by another buddy that’s a smaller blue triangle”
- Took 6 minutes to get the first working version
- Iterated step by step: first it followed the cursor, then it could hear him, then it could reply
- He doesn’t know Swift and can’t review the codebase—but has been building products since age 18, which is why he can direct the build effectively
Clicky’s evolution
- Original version randomly popped up like a friend and recommended music or videos as he browsed—a “push” model
- Current version (used by thousands daily) is simpler: tap it once, talk to it, it replies—a “pull” model
- Can watch the screen, listen, and give contextual help (e.g., “Click that play button or press Command R” in Xcode)
Landing pages in one shot
- Told Claude Code to read the Clicky codebase and “make a sick landing page”—black and white, one page
- It produced the live landing page almost exactly as-is
- Uses Vercel (Next.js) for web projects because of how fast it is to deploy
General build philosophy
- No tool allegiances—uses whatever is fastest, whether Claude Code, Codex, or something else
- Always builds his own first use case before considering what others might want
- Asks Claude: “What’s the quickest path to shipping this idea?”

Content is built for his own lens
- Treats himself as the audience—if he finds it interesting, others will too
- Doesn’t spend much time consuming social media; he’s a producer, not a consumer
- Uses a shot-list approach even for short demo videos: 3 bullet points, 45 seconds, done
Twitter/X usage is minimal and AI-mediated
- Uses Pro.X.com and only checks notifications—no feed browsing
- Uses Grok to summarize the top 10 AI tweets of the day (new announcements, no drama) instead of scrolling
Screen Studio for video production
- Swears by Screen Studio for screen recordings—gives fine control over cursor size, style, zoom, and camera placement
- Uses it for all his demo videos
AI-assisted guest research
- Before meetings, asks an AI to deep-research the person and generate a PDF placed on his desktop
- Example: researched the podcast host Julia beforehand to confirm he wasn’t “weird”

Black paper notebooks are for things worth remembering
- Uses black-paper notebooks (as opposed to white paper for things meant to be thrown away)
- Draws and writes in them—the physical act helps him retain and reference ideas
- This analog layer is not separate from his digital stack; it’s the foundation that feeds everything else
