I kept losing valuable ChatGPT work because copy/paste destroys formatting and most export tools upload your chats to servers.

So I built Chat Export with one rule: everything stays on-device (offline + encrypted, no accounts, no cloud).

It preserves images, code blocks, tables and exports to PDF / Markdown / HTML / TXT in one tap.

If you try it, tell me: PDF vs Markdown - which do you need most and why?

I came to exactly the same conclusion that real startup ideas often come from simple and boring problems. From my own experience: I spent three years on a startup that was supposed to revolutionize online education, but in the end it had 0 users. Now I ve just started solving a simple problem for home appliance repair technicians and immediately got my first paying users on a very rough MVP.

1. Need an AI Jarvis that turns chaotic voice/text updates into automatically structured tasks, projects, and dashboards for managing all of life and work.

2. Hours of manual searching for parts for Chinese cars. Need an AI agent that understands queries from photos or text and finds the part.

3. Online clothes shopping is a lottery. There's no accessible technology to see how an item will fit your body, especially in small stores. It's a pain for the buyer and a loss for the seller.

4. A musician from Lebanon cannot sell his music: streaming pays pennies, and Bandcamp doesn't accept payments in his country. Needs a fair radio-platform with direct sales.

5. VPN users have nowhere to find out if a service will work reliably on their network there is no up-to-date rating based on real-time quality monitoring.

6. It's impossible to order truly fresh farm vegetables and bread through delivery aggregators product quality is low, and you have to go to the market yourself.

New AI models pop up every week. Some developer tools like @Cursor, @Zed, and @Kilo Code let you choose between different models, while more opinionated products like @Amp and @Tonkotsu default to 1 model.

Curious what the community recommends for coding tasks? Any preferences?

1. The lack of a service that creates hyper-personalized, gamified English courses (in the Duolingo format) for narrow professional niches (e.g., for a barista in a vegan coffee shop or a startup founder.

2. Automating cross-posting of an indie hacker's technical content across multiple platforms (Twitter, LinkedIn, Product Hunt) while adhering to each platform's best practices.

When Opus 4 was launched, it was quite a leap, in my opinion. That's why I'm interested to hear your real impressions of the newest Opus 4.5 by @Claude by Anthropic.

• Have you noticed any improvements in your workflow?

• Are there any annoying features like the notorious limits for Opus 4 in Claude Code?
