Here's a list of my favorite apps and tools, organized by how I use them.

💡

****Bottom line up front:** If an app ****decreases friction** in a productive activity, I'm going to consider paying for it even if cheaper alternatives exist.

## AI

I use five AI tools on a daily basis, each with a distinct superpower:

- [Claude](https://claude.ai/new?ref=jeffsu.org) \- My go-to for writing, analysis, and anything that requires nuance. I also use [Claude Cowork](https://coworkacademy.ai/toolkit?ref=jeffsu.org) to run my entire business operations.
- [ChatGPT](https://chatgpt.com/?ref=jeffsu.org) \- When I need the AI to follow instructions precisely without improvising, ChatGPT is the most obedient.
- [Google Gemini](https://gemini.google.com/?ref=jeffsu.org) \- Handles images, video, and Google Workspace integration better than anyone else. Want to test this? Upload a YouTube video and ask Gemini to summarize it with timestamps.
- [Perplexity](https://perplexity.ai/pro?referral%5Fcode=PEDDZAKZ&ref=jeffsu.org) \- Fast, cited answers with real sources. My default when I need to look something up.
- [NotebookLM](https://notebooklm.google.com/?ref=jeffsu.org) \- Upload your own documents and get answers grounded in what those documents actually say. No hallucinations, no made-up facts.

**Edge cases:** Midjourney and Google's ImageFX for image generation, ElevenLabs for voice, Runway for video.

## Productivity

- [Wispr Flow](https://wisprflow.ai/r?JEFF306&ref=jeffsu.org) \- This app completely changed how I interact with AI. We all talk much faster than we type, so I find myself defaulting to talking (especially when I have a lot of context to share) instead of typing. The intelligent auto-editing feature is insane.
- [CleanShot X](https://cleanshot.com/?affiliate%5Fid=529753203&ref=jeffsu.org) for Mac - Hands down the best screenshot app I've ever used. My favorite feature is the ability to make any screenshot "social media-friendly" in one click (adds a gradient background and crops perfectly).
- [Todoist](https://geni.us/jefftodoist?ref=jeffsu.org) \- The best tool for quick capture I've come across. An essential part of my [CORE Workflow](https://www.jeffsu.org/productivity/).
- [Notion](https://ntn.so/jeffsunotion?ref=jeffsu.org) \- I use Notion to organize my entire life and business. My [Notion Command Center](https://us.ppacademy.cc/project/1DDE389A5651FDE381C38DD34B8FB5CD/about?utm%5Fcampaign=ppo%5F1DDE389A5651FDE381C38DD34B8FB5CD&utm%5Fcontent=youtube&utm%5Fmedium=jeff%5Fsu&utm%5Fsource=teacher&utm%5Fterm=180&ref=jeffsu.org) runs everything from project tracking to content planning.

## Mac Apps

- [Alfred](https://www.alfredapp.com/?ref=jeffsu.org) \- If I had to pick one app from this entire list, this would be it. The free version is more than enough for 99% of people, but I upgraded for the Snippets (text expander) feature. Check out [my Alfred tutorial](https://youtu.be/FXV-zwkRMxo?ref=jeffsu.org) to learn more.
- [Rectangle](https://rectangleapp.com/?ref=jeffsu.org) \- Free window snapping for Mac. Simple, reliable, does exactly what you need.
- [MonitorControl](https://github.com/MonitorControl/MonitorControl?ref=jeffsu.org) \- Can't believe this is free. If you have an external monitor, this is a must-use.
- [AppCleaner](https://freemacsoft.net/appcleaner/?ref=jeffsu.org) \- Best uninstaller app there is. Drag and drop, done.
- [Maccy](https://github.com/p0deje/Maccy?ref=jeffsu.org) \- Free and open-source clipboard manager.

## Self-Improvement

- [Readwise](https://readwise.io/jeffsu/?ref=jeffsu.org) \- I take notes while reading non-fiction books but I often get lazy and never review those notes. Readwise sends me 5 highlights via email each day and I find myself actually applying resurfaced content in my daily life (i.e. sounding like a douche by quoting books I've read).

To be clear, I don't think Readwise is a good replacement for actually taking comprehensive notes and reviewing them consistently, but something is better than nothing. You can [watch me talk about it here](https://youtu.be/99-bTIKU8OE?ref=jeffsu.org).
