Take a look around.

Walk through a city made from mock sessions. Select a building or replay a day. Your own records stay untouched.

01 / EVERY BUILDING HAS A BACKSTORY

Every building
has a backstory.

Every session leaves a trace. Oh Agent gives you a place to explore where it came from, how much it used, and when it happened.

Selected demonstration building with session source, tokens, time and event details
Actual product view · demonstration workspace
  1. 01

    A session becomes a building.

    Select a data building to see its source, recorded activity, and token usage.

  2. 02

    Your sources shape the skyline.

    Agent tools form districts. Token volume shapes building height. Decorative buildings are separate from your sessions.

  3. 03

    Your history has a rhythm.

    Replay activity within the loaded time range and explore how the view changes over time.

Building height represents token scale, not productivity. Construction and growth are visual metaphors, not task completion. The app shows how much of your history is loaded.

02 / FOLLOW YOUR CURIOSITY

A little curiosity.
A clearer picture.

Follow your curiosity beyond the skyline. The Mac app offers usage, cost basis, and session evidence when you want a closer look.

01 / USAGE

See where activity adds up.

Review token usage by source and time, then look into the sessions behind a busy day.

Illustration · sample data
02 / COST BASIS

Know what a number means.

Keep subscription fees, usage-based estimates, and evidenced spend distinct. Unknown prices stay unknown.

Subscription / month
$20.00
API-equivalent estimate
$14.60

Sample amounts. An estimate, not a bill or money saved. Separate analysis view; cost is not shown in City.
03 / SESSION EVIDENCE

Find a session worth a look.

Explore available traces and supported signals such as consecutive tool failures. Review the evidence in context.

Illustrative sequence. A retry is a clue to inspect, not proof of wasted work.

03 / A PERSONAL WORLD

Your work is personal.
Your world stays local.

Your sessions hold your work, ideas, and context. Oh Agent analyzes supported records on your Mac. Session data is never uploaded for analysis.

BEFORE YOU STEP INSIDE

A few things
to know.

Is the sample city using my data?

No. This website uses synthetic sample sessions. It never reads your local agent records. Your own city is generated by the installed macOS app using supported local records.

Which agents and computers are supported?

The desktop app targets macOS on Apple Silicon. Sources include Claude Code, Codex, DeepSeek Harness, and WorkBuddy; available statistics, traces, and cost evidence vary by source and version. Intel, Windows, and Linux desktop support is not currently claimed. Check the release notes before installing.

What does a building represent?

Data buildings represent loaded sessions. Their height reflects token volume, and sources form districts. Decorative buildings provide scenery. Building growth is a visual metaphor and does not measure task completion or output quality.

Will I see my complete history?

The current City view loads up to 500 recent sessions within the selected time range and reports its coverage. Available history depends on the records your agent tools retain. Missing records are not replaced with invented activity.

What if I have no data yet?

Use a supported agent first so it creates local records. In the desktop app, check source status, permissions, and synchronization. No records, denied access, and read failures require different follow-up steps; the website sample remains available to explore.

Are costs actual charges or savings?

Usage-based amounts can be estimates, not charges. Subscription fees and evidenced spend are shown with their own basis; currencies are not directly added together. Comparing a subscription with an API-equivalent estimate does not prove money saved. City itself does not currently project cost data.

Do I need an API key or an account?

No API key or cloud account is required for local analysis. The app reads records your supported tools already leave on the Mac; macOS may require permission to read those locations.

Where can I download it and inspect the code?

The project code is MIT licensed. The configured public repository and release URLs are not currently accessible anonymously. Public download and source links will appear here after they are verified. This preview does not offer an available download.
