What is Kari
Kari (かり・雁, Japanese for “wild goose”) is a user-centric AI agent application for reading through your local files together with AI and getting work done. It brings everyday tasks into a single screen, including drafting emails, summarizing and translating documents, drafting slides, analyzing data, researching the web, vibe coding, and browser automation. There is no need to re-upload files into a chat window — Kari works directly with the files already on your machine.
Along with signing in with your Claude or ChatGPT subscription, Kari comes pre-configured for more than 70 AI providers (including Google Gemini, Microsoft Azure, and local LLMs), and also supports adding your own providers and running local models. With Kari you get AI agent capabilities without any additional development. Combine it with OumiGo, and you can easily build a self-contained AI system within Japan.
The interface and the documentation are both fully available in Japanese, and Kari is designed for use in Japanese-language environments.
Use cases for Kari
- Summarize meeting notes and PDF / Word documents
- Translate PDF, Word, and PowerPoint files
- Draft PowerPoint presentations
- Aggregate and visualize Excel data
- AI agent data analysis: have the agent parse and type raw CSV, Excel, and SQLite data, then run correlation and segment analysis, build charts, and draw out insights
- Create flowcharts
- Search web pages, and search across large numbers of local files
- Vibe coding
- Browser automation: on sites with no Web API or MCP support, the built-in browser carries out search, navigation, and downloads for you (parliamentary records, court decisions, government statistics, social media trends, and more)
Automated data analysis with AI agents
Kari now supports data analysis by AI agents. You can hand the agent the whole sequence: working out the structure of the raw data, aggregating and correlating it against your hypothesis, building the charts, and drawing out the insights. Cleaning, reshaping, and aggregating raw data has traditionally taken significant effort, and every change of hypothesis meant repeating the same work. With Kari that repetition finishes quickly, so you can get through more iterations in the time you have.
Register a CSV, Excel, or SQLite file in a data collection and Kari works with it as a table, referencing the file where it sits rather than copying it. Ask for AI parsing and the agent determines and applies the right type for each column — and because it leaves the work behind as a Python script, you can go back and check exactly what was converted and how. Give it an analysis instruction next, and the filtering, derived variables, correlation analysis, and charts are saved together as a data flow, ready to re-run when you revise the hypothesis.
The documentation walks through two worked examples built on Japanese public statistics.
- Tokyo real estate price analysis with AI: 207,636 transaction records (28 columns, 39.3 MB) for the 23 wards of Tokyo from the MLIT Real Estate Information Library — parsed, then analyzed for the correlation between the per-square-meter price of pre-owned condominiums and 26 other variables, the price growth rate by segment, and the correlation between that growth rate and population change across the wards
- Inbound consumption trend analysis with AI: published Excel data from the Japan Tourism Agency and JNTO, parsed and joined, then analyzed for visitor-count and total-spending trends by nationality and region
If you are going to act on the results, always check the figures the AI produces against the source data. Each documentation page marks the places worth verifying under “Human-in-the-loop のポイント”.
