The AI assistant that started it all.

AI & MLFreemium★ Editor’s Pick

🎯 Why it’s useful

It compresses an hour of "looking something up" into 30 seconds. The Plus plan ($20/mo) unlocks GPT-5 and the desktop app, both of which are huge upgrades over the free tier.

💜 Why we like it

The desktop app + voice mode is genuinely the fastest way to think out loud. We use it as a rubber duck for product decisions every day.

🎯 Why it’s useful

Founders drowning in emails can automate routine responses and focus only on high-priority messages, saving hours each week on inbox management.

💜 Why we like it

It's like having a smart EA who actually understands context and can handle the email chaos without you micromanaging every thread.
