You spend 4-7 hours a day pouring your life onto your phone, yet your current AI is blind, dumb and stuck in a box :(
It's blind to your world.
Your calendar knows you're meeting 'sarah.' your notes have the details. but your "smart" tool can't see any of it.
But…
There is hope!
Secondly, the proactive sidekick you’ve been missing
It sees what you see.
Secondly can see your screen, proactively jumping in with context right when you need it.
Oh, and it is yours.
A sidekick that sees what you see, thinks how you think and acts how you act.
Secondly isn't a tool you rent, it's a clone of your mind that you own.
A sidekick that sees what you see, thinks how you think and acts how you act.

FAQ
FAQ
FAQ
Is this just another ChatGPT wrapper?
No. ChatGPT can't access your tabs, fill forms, or run automations. We're a full browser replacement that happens to use AI. Think Cursor, not VSCode.
Do I need to learn commands or prompts?
Zero learning curve. Just browse normally. Dafdef learns your patterns and suggests automations. The more you use it, the smarter it gets.
Can I use the AI key without the dafdef browser?
Not right now. You need to have the browser installed so we can route the LLM requests of the Key.
Is my data private?
Yes. Your browsing data stays on your device. We only process what you explicitly ask the AI to handle. No creepy tracking.
Why iPhone only?
We're mobile-native, not a desktop port. 21% of Gen Z doesn't even own a laptop. We're building for the future, not the past.
