When you are coding with AI its extremely helpful to give the models a way to check if the code is working out or not.

Never tracked user engagement before. Evaluated a few solutions and settled on PostHog.

Session replay is cool. You can watch exactly what users did on your site. Plus heatmaps, error tracking, LLM tracking, and anonymous cookie-less tracking.

I built this cool looking animation for my landing page. Didn't know how easy and fast this is.

Life hack for cheap people: min-max all the free AI tiers.

Chat: ChatGPT, Claude, Mistral, Gemini, Perplexity
Code: Codestral, v0, Bolt, Lovable

Is it ridiculous? Yes. Does it work? Also yes. 🤫

Why is no one talking about boring stuff like paying taxes, dealing with legal stuff etc?

People with successful business are often big on X. But What comes first?
Are they big on X because they have business success?
Or do they have business success because they are big on X?

Over the past month, I compared the Cursor and Antigravity
Verdict: No big differences. Both are essentially just VSCode clones with AI features.

Antigravity has free credits. That's probably its biggest advantage.
However Cursor seems a bit more mature and offers more models.

The best way to learn how to code:
1. Find something you genuinely want to build
2. Start coding immediately
3. If you hit something you don't understand: Search for a tutorial or discuss with you favorite LLM. Take your time to learn/understand it. Go back to 2. instantly.

I build a calendar agent with full read/write access to all connected events.

But how to continue? It can do almost anything:
- Retroactively fill timesheet for invoices
- Plan future events
- Summarize month, compare weeks, find inconsistencies, etc
