While everyone is going bonkers about Claude Cowork, I look at a really cool alternative, fittingly named "Alter." See what's is all about...

🧵 Teach Alter Your Defaults

1/ What if your AI assistant actually remembered who you are? Not in a creepy way, in a useful way.

Today, we're introducing Manage Settings, the first step toward giving Alter memory and a lot more.

[alter | Contextual AI for Mac @alterhq_]

3/ The most powerful setting? Your persona.

Tell Alter who you are and how you work.

"I'm a senior software engineer specializing in cloud infrastructure. I prefer concise, technical explanations with code examples."

Now every interaction becomes more relevant, more useful, more you.

Better with the Live Notepad video: https://t.co/iPzMq5MgaM

Stop taking notes like it's 1995.

We just shipped Live Notepad. It's an AI assistant that sits next to your meeting and actually helps you capture what matters.

No more choosing between listening and typing.
