Most teams run on a dozen SaaS tools and use maybe 20% of each. The rest is someone else's workflow that you're paying for.

We built Yansu to fix that. It learns how you work — your desktop, your Slack, your Teams — and proactively builds bespoke tools tailored to you. You don’t need to prompt. It sees a pattern, builds a solution, and surfaces it for you to use or toss.

Like, I do the same things before every call: look through Linkedin, see any open threads on email, read the latest blog/news of the company and any relevant slack conversations. Yansu noticed and built me an app that pulls all of the information together. I can always browse it before / during / after the call now.

How Yansu works:

Listen — learns from your desktop activity and messaging apps Crystallize — distills patterns into structured knowledge about how you work Solve — builds tools based on that knowledge, without being asked

It builds apps/GUIs when you need to see things, CLIs when you need to automate or script things. Depends on what it learns about how you work.

Everything processes locally on your machine. When it needs an LLM, it sends structured context to whatever model you configure, be it Claude or GPT.

Free tier: bring your own agent, no credit card. $20/mo if you want managed AI. Available from today on macOS, Windows, Linux.

Turn that exploratory work to product would be the challenges. It is hard to balance the two

Background:

We been helping mid-market companies for the past 1.5 years and finally ready to share the internal platform publicly. Yansu (严肃) is a AI coding platform that use spec + TDD to build complex software projects. It is more like a SOP than coding agent. We focus on understanding requirements and checking outcomes against those requirements while iterating the code based on the tests.

Yansu tries to learn as much tribal knowledge as possible. These are things you don’t write down in google doc or Notion. Yansu absorbs these knowledge by continuously talking to users and distilling learning from them.

It's as if a spec + TDD platform had a baby with character.ai.

Why care about requirements? B/c 80% of any software development is understanding requirements and what exactly we want to build. We also focus on outcomes, the only thing that matters. We deliver satisfying outcomes by simulating scenarios and generating tests based on those scenarios. Our agents take that tedious testing part of the code away from others.

We prioritize accuracy over latency/cost, using a mixture of agents (not limited to CC, codex, and etc) to get the job done. We then run through continuous-testing-generating pipelines until all things pass.

What does Yansu mean? “Serious” in Chinese. Just like my favorite artist, Rene Magritte, painting in his kitchen in a suit. I want to give my coding respect and care.

Our goal is to level people up from IC to tech leads, to work on the high leverage work of planning, validating, and educating.

We made a launch video to celebrate human work that builds on all of the creative minds before us. Shoutout to CinemaSings for making this happen.

The job of human is providing teaching via feedback. Your manager does the same thing to you too. And you can distill those feedback into learnable experience for your llm to be better next time.

We are not automating ourselves out of the job, we are changing the nature of the job. From writing to teaching.
