Introducing Clastines: Your AI-Native Work Assistant (Not Just Another AI Tool)

Clastines is an AI-native work assistant designed to act like a colleague, with approval-first actions you can trust.

Clastines AI-native work assistant

We're reimagining how professionals interact with technology. Clastines isn't just another AI tool -- it's your dedicated digital colleague.

Most software still treats you like a human router.

You receive messages. You triage. You forward. You summarize. You chase context. You follow up. You schedule. You re-explain the same thing, again and again -- just with different names.

Over time, work becomes less about thinking and more about managing the flow.

AI promised to fix that, but the reality has been mixed. Plenty of tools can generate text. Fewer can operate inside the messy reality of professional life: threads, timing, tone, and consequences.

That's the gap Clastines is built for.

The shift: from tools to a colleague

A tool waits. A colleague anticipates.

Clastines is designed to behave like an assistant that can:

  • understand what you're working on (context)
  • help you move faster (draft, summarize, prioritize)
  • and keep you in control when actions matter (approval-first)

That last part isn't a footnote -- it's the difference between a cool demo and something you trust with your reputation.1

How this compares to what exists today

Let's be real: the world already has AI email.

  • Superhuman markets itself as AI-native email, with features like drafting, instant reply, and auto-summaries to help users move faster through threads.2
  • Shortwave leans into AI organization -- summaries, writing help, and even AI filters that can label, star, or archive using natural-language rules.3
  • Microsoft Copilot in Outlook supports thread summaries so you can catch up quickly.4

Those are strong products. But they largely live inside one surface area (email) or one ecosystem (like Microsoft 365).

Clastines is going after something slightly different: an AI-native work assistant that helps you manage communication as a workflow -- not as a pile of messages.

What AI-native means to us (in plain English)

AI-native doesn't mean we added AI to a dashboard.

It means:

  • the assistant is the interface
  • context is the default
  • and the output is built for action (with oversight)

A lot of AI email tools optimize for speed (reply faster, read faster), which is valuable.2 Clastines also optimizes for continuity -- so you stop losing time to reloading context and re-deciding the same thing.

Why this matters now

Work has changed. Communication volume has exploded. Expectations are instant. And the hidden tax is attention: context switching, inbox anxiety, and the feeling that your day got spent reacting.

We think the next era of work software is not more features. It is delegation -- done safely.

The Clastines promise

Clastines exists to help you spend time on decisions, not busywork.

If you've ever finished a day thinking: "I didn't do my real work -- I just managed messages," then you already understand the problem we're solving.
