I build AI software and care how it feels to use

I joined the team that became flowith in November 2022, before the company was registered. I wrote Mirro’s front end from the first line and led the architecture of flowith’s first version. Later I worked on the flowith browser, and on Matrix and Agent.Space from day one. What bothers me is any moment where someone has to pause and figure things out, or learn something first. If I find one, the feature isn’t finished.

Mirro’s first screen: a chat where its AI picks up the conversation

02Mar 2023 – Aug 2025

Mirro AI

An AI app for the people you half know

A person can keep up about a hundred and fifty relationships. Mirro used language models to keep track of the people you half know, and to keep conversations going. In June 2023 it was pitched at MiraclePlus’s spring demo day in Beijing, with the line “Dunbar’s number, times ten.”

flowith

A canvas for making things with AI

I wrote flowith from its first version in 2023, front end and back end. The team was small, so product and interface calls often fell to me too. In 2024 I started on the agent behind Oracle mode: how it breaks a task down and how it calls its tools. Nothing off the shelf could do it then, so I wrote it from scratch; it later became Agent Neo. I also open-sourced canvas-cowork, the part that lets agents work directly on the canvas.

Matrix

You set the goal. Matrix hands the work to a team of agents, keeps them going until it’s done, and checks the result before handing it over.

Software for a few more aha moments

For now it’s just me, making two things. Mochi sits in your Feishu group; Galta opens beside the page you’re reading. Neither takes learning, and both run on your own Mac and AI account. Mochi is a felt cat; the mark is a ring of ‘ahaha’, a laugh.

Mochi

A cat that lives in your Feishu group and reads your GitHub

Someone asks, “Is this live yet?” It goes through the repo and comes back citing its sources. When the group settles something, give a nod and it files an issue with an owner. At the agreed time, it reports back to the group.

Galta at work: a circled cup, before and after “Make the cup terracotta”

Galta

A canvas that opens beside the page you’re on

See something you like, drag it in. To change something, circle it and write a line. It works from the whole canvas and the page beside it, and makes images, video and sound.
