LINA, sitting at a sunny table with a blue mug

Someone who remembers you, and finishes what she starts.

We are Chotree, a small company in Seoul. We make LINA, a personal agent, and Aegis Alpha System, an open-source engine for investment research.

LINA is one ongoing conversation that follows you across devices and years. You can talk about your day, think out loud, or bring her a problem. She remembers what you have already tried and picks up on what keeps coming back.

When something is worth doing, LINA takes it on: research, planning, the actual work, and checking that it works. She coordinates the agents doing each task and reports back in the same conversation. You decide what matters and whether the result is right.

No reintroductions

New laptop, new phone, same LINA. Your history comes with you.

Done means done

A task is closed when there is proof it works, not when a model says so.

Nothing gets lost

Decisions and results are versioned, so you can look back and restore them.

Works with your tools

GitHub, Google and any MCP server. Every change she makes is recorded.

“You bring the intent. LINA carries it through.”from the LINA manifesto

Aegis Alpha System

A Python engine that handles the data and math behind investment research, so apps and agents can rely on its numbers. It covers asset allocation (Aegis), single stocks (Alpha) and defensive positions (Hedge).

  • Data with a historyPrices, financials and macro data are stored with their source and every revision.
  • As of any dateInputs are read as they were known at the time, which keeps backtests honest.
  • Repeatable runsEach backtest returns a hashed receipt you can check again later.
  • Runs on your machineSQLite and DuckDB built in. No database server to set up.
# install and check $ uv tool install . $ aas init $ aas doctor # run a registered strategy $ aas db run-install $ aas run execute --request request.json --sha256 <hash> → run-0123… status SUCCESS certified false

AAS is a research tool. It does not place live orders or give investment advice.

About

A small company that got tired of copy and paste.

Chotree started in February 2023 in Seoul, selling online and doing investment research with very few people. Most of our time went into carrying information from one tool to the next. LINA and AAS came out of wanting that work done for us.

We build both with Claude and Claude Code.
