This was the assessment from ChatGPT with the custom instructions loaded:
Overall: 3.5/10

tl;dr - The idea didn't score great in either thread...
BUT the reply without the custom instructions was just positive enough where an inexperienced founder might try to go build this idea, a la working on a tarpit idea.
Custom instructions = clearly a bad idea

This is beautiful 🤩
Flash inspired me to learn how to code.
i recreated Flash in the browser just to feel alive again.

$30M will fund a lot more spam 🫥
Polsia just raised $30M at a $250M valuation.
Approaching $10M annual run rate.
One Founder AI. Zero employees.
Polsia runs companies autonomously.
It also ran its own fundraising.
I just showed up for signatures.

All these accounts sharing obvious "million dollar ideas" for businesses and apps that can be built using AI are so weird to me...
If the business was that easy to build and scale, why would you share it and not just build it yourself?

A lot of founders say they want AI agents, but then you look at some of their processes and it's just 7 manual steps, poorly documented, and nobody bothered to write it down properly.
So the agent is supposed to magically understand the messy thing the team itself can't even explain?
Not how it works. Make sure you have super clear guidelines for your work, clear enough that any human (VA, support staff, etc.) could follow it easily. Then you can deploy AI.

You gotta love seeing @Lovable opening up a Boston office.
Great talent hub for seasoned GTM/engineering hires, and hopefully helps keep more graduates in the area.

We officially opened Lovable’s first US office in Boston.
Boston felt like the right place for us to open an office because Massachusetts has a practical view of AI. It’s about using AI to solve real problems rather than just building the technology, which is something Gov. Maura Healey has spoken about clearly.
That’s why we started Lovable, to help more people turn ideas into software, products, companies, and real economic value.
PS, check out Gov. Healey rocking our Lovable socks.

Are there automated tools now that just find popular tweets, slightly tweak them with AI, and then auto-post the imitation for engagement farming?
This seems buildable now, and if the audiences didn't overlap, readers would never know...

Seems like Claude is down... API Error: 500
I guess it's time to eat so I can use my carbon-based AI (aka brain)

In less than a year, we managed to get more than 13M organic views on Reddit.
It brought over 100,000 people to our website without spending a cent.
We put together a Reddit Strategy Playbook that gets me 1M organic impressions/month… and makes my posts show up consistently inside AI outputs (ChatGPT, Gemini, etc.).
Here’s what’s inside the playbook:
😈 How We grow my SAAS gojiberryAI with Reddit
🔥 The 3 1 post formats that always go viral
🚫 How to get traffic from 100 subs → without getting banned
🔎 Our Reddit SEO method to rank in AI-generated answers
⚡ The automation flows we use to convert views into demos
🏴☠️ A little bonus just for you
Want the full 1M Views/Month Reddit Strategy (100% Organic)?
Here’s how to get it:
✅ Repost this post
✅ Comment “REDDIT”
I’ll send it straight to you.

This is one of those “obvious when you see it” ideas.
It gives you personalized coaching on all your one-on-ones, sales demos, customer success calls, etc. Can also do role playing for pre-meeting practice.
Perfect for people who strive for constant improvement.

Today's meeting tools give you a transcript, but nobody tells you how you did. I'm so excited to announce Work Coach (a new mac meetings app).
Work Coach helps you by:
- Observing you in meetings (interviews, 1:1s, sales calls, team meetings)
- Analyzing how you show up to those meetings
- Identifying opportunities to improve
- Replaying the exact moments from your meetings where it happened
- Role play conversations (intros in an interview, asking for a raise, etc)
- Interviewing your coworkers to get feedback that you're not getting
I'll put the download link below.

Curious if this basically forces people to stop following company Twitter accounts that follow thousands of accounts:
@HubSpot ~38,000
@SlackHQ ~121,000
@buffer ~54,000
Interestingly, most of the AI companies follow almost no one…
@claudeai - 1
@OpenAI - 4
@cursor_ai - 43

We're testing a new reply setting on posts:
We're expanding the "Accounts you follow" option to include their followers too: your 2nd degree connections.
This allows a wider audience to participate—but still keeps things intimate

What if Granola and @lennysan had a baby? That's what I built into Work Coach. World class insights personalized and delivered when most helpful.

Today I'm releasing my entire newsletter archive (350 posts) and all podcast transcripts (300 episodes) as AI-friendly Markdown files. Plus an MCP server and GitHub repo.
A few months ago I shared my podcast transcripts on a whim, and y'all built the most amazing things—an RPG game, a parenting wisdom site, infographics, a Twitter bot, and 50 other projects.
Let's see what happens when I give you even more data.
Grab the data here: LennysData.com.
Paid subscribers get all of the data (some 350 posts and 300 transcripts). Free subscribers get a subset.
I don’t think anyone’s ever done anything like this before, and I’m excited to give you this excuse to play with that AI tool you've been meaning to try.
Here’s my challenge to you: build something, and let me know about it. I’ll pick my favorite and give you a free 1-year subscription to the newsletter. Just post a link to your project in the comments here: lennysnewsletter.com/p/how-i….
If you’ve already built something, slurp in this new data and submit it, too. I’ll pick a winner on April 15th.
Check out today's newsletter post for inspiration on what you could to build: lennysnewsletter.com/p/how-i…
LFG.
