Kinso — Unified Inbox

Product design, AI, Design systems

Kinso puts a working day in one place: a calendar, an AI that has read your messages, and one inbox for Gmail, Slack, WhatsApp, LinkedIn and Instagram. I designed across the product as Staff Product Designer, from the home screen to the Kin design system.

The problem

A working day is spread across five inboxes and a calendar

A founder or executive has five inboxes and a calendar in another tab. The work of the day is knowing which three of a hundred messages actually need them.

Gmail

For investors.

Slack

For the team.

WhatsApp

For the people who matter most.

LinkedIn

For recruiting.

Instagram

For everything else.

A unified inbox is easy to draw and hard to make useful

Pulling five sources into one list is solved. Making it useful is not: a Slack thread and a WhatsApp voice note should not pretend to look alike.

Where Kinso started

The first version opened on a greeting and a count: four new and nine active conversations. Expanding the briefing gave a long, accurate summary: one more thing to read before you could act.

My role

Across the whole product, through Owlry

I led design across Kinso through Owlry, my design studio, including the AI panel and mobile. I worked with the Kinso team and engineering through to a Figma-to-code workflow, so what shipped matched the design.

The process

Write the day down first

Learning from the products people already use

What we learned

Superhuman

How far speed and keyboard flow can carry email, and how AI can schedule from a thread.

What we learned

Fyxer

Automatic categorisation, and drafts in your own voice.

What we learned

Beeper

How many chat networks can share one inbox and keep their identity.

A mood board of calm, high-trust tools set the tone: Kinso had to feel quieter than the products it pulled from.

The day as a flow

The key flow

  1. ArriveOpen Kinso
  2. OrientWhat needs me today?
  3. ActHandle what matters
  4. EvolveA new signal
    Go deeperResolve
  5. Wind downEnd of day
  6. TomorrowA clean slate

And tomorrow starts again

Every surface had to earn its place in one of these steps.

The flow became the spine of home, inbox and calendar, and the filter for every later feature request.

Ideation

I explored home as cards that each carried one decision, such as an offer pending or a payroll discrepancy.

The card became the unit of the product, with three next steps on hover: done, remind me later, or more.

The solution

Orient, act, get back to work

Orient before you act

Home does not open on 40 unread messages. It opens on one sentence saying what has been cleared and what needs you.

What's been cleared

"We've cleared 13 conversations for you" comes first, and one click shows what was set aside.

A later direction grouped the day by topic and by the action needed: a reply, a decision, or a promise.

Home grouped into actions across topics

One inbox, five sources

The inbox groups by priority, unread, unanswered and everything else, and each conversation keeps its source icon.

One inbox, five sources

Threads with the context already read

Beside each conversation, Kinso's brief gives the decision in two sentences, related conversations from other sources, and the next actions.

A calendar people trust

To move a real week in, the calendar needed the unglamorous details: dragging across days, time zones, several accounts, and editing one repeat without breaking the rest.

The design system

Kin: a calm frame around five products

Kinso shows other products' content, so its own interface had to recede. Kin uses warm neutrals, quiet surfaces and a few components that hold any kind of message.

Foundations

Every foundation is a token shared with engineering.

Figma to code

Tokens and components in Figma mapped directly to code.

The impact

One frame, one library, one day

Home, inbox and calendar were all designed on Kin, giving engineering one component library and the product one calm frame. The flow gave the team a shared way to decide what to build, and what not to.

Reflection

The flow kept the product honest

Every feature request had to belong to a step of the day. If it didn't, it didn't belong in Kinso yet. Next time, I would test the flow with real users earlier.
