GitHub Copilot Sessions Viewer

A local viewer for listing, inspecting, and searching the history of GitHub Copilot CLI sessions, including sessions from the GitHubCopilot VS Code extension. You can also attach labels to content you want to remember and search for it later.

This tool supports Japanese / English / Simplified Chinese / Traditional Chinese.
Feedback and feature requests are always welcome. Feel free to open an issue.
The first launch is relatively heavy, but after the initial load completes, the app runs quickly thanks to caching.
- Lazy loading is planned soon to improve startup speed further.

How to Start

Download the app-framework-dependent folder from Releases, extract it, and then run run.cmd inside it.

Note: Running this tool requires either the .NET 10 SDK or the .NET 10 Runtime. If you are not sure whether it is installed, or you prefer not to install it, download the app-self-contained folder instead.

Note: If you want to build from source, run the following PowerShell script.

Framework-dependent build (if the .NET 10 SDK or .NET 10 Runtime is already installed)

.\publish.ps1 -CleanOutput

Self-contained build (if the .NET 10 SDK or .NET 10 Runtime may not be installed, or you do not want to install it)

.\publish.ps1 -SelfContained -CleanOutput

UI Features

Header
- Language switcher (日本語 / English / 简体中文 / 繁體中文) in the upper-right corner
- Buttons for Label Management, Cost View, Meta View, Shortcuts, and toggling the list view on mobile
- A "Today's usage" summary below the header so you can quickly check REQUEST and PREMIUM REQUEST
- Meta View is hidden by default. It can show the selected session's session root, path, cwd, time, source, events, and raw lines
Left pane: session list
- Two tabs: Session List and Label List
- Displays sessions with source (CLI / VS Code), session labels, and last updated time
- Shows the count as sessions: filtered/total at the top of the list
- Sorting tabs for Newest First, Oldest First, and Last Updated
- Clear resets the search and filter conditions in the left pane
- Show Filters / Hide Filters collapses or expands the search and filter area
- In vertical layout, Hide List / Show List in the upper-right header toggles the entire left pane
Left pane search and filters
- Filter by cwd / Start Date / End Date / Event Start DateTime / Event End DateTime / keyword / source / session label / event label
- In the keyword field, text wrapped in double quotes is treated as a single phrase
  - Example: search "Working Space" as one phrase
- cwd / date-time / source / label conditions are always combined with AND
- The AND/OR toggle applies only to the keyword field
  - AND: must contain all space-separated keywords
  - OR: must contain at least one of the space-separated keywords
- The time field for event date-time becomes enabled after the corresponding date is entered
- Filter conditions are preserved for the next launch
Left pane label list
- Labeled sessions and labeled events are grouped by label
- Distinguishes message, function_call, function_output, and agent_update
- Clicking an item jumps to the target session or event
Right pane: chronological event view for the selected session
- Shows a loading indicator on the first detail load, and an updating overlay during manual Refresh
- The detail toolbar is organized into Display, Actions, Search, and Range Selection
- Detail Actions, Search, and Range Selection can each be expanded or collapsed independently
- When no session is selected, display, search, and range-selection controls are disabled
Right pane display and actions
- Display options: "Show Only User Instructions" / "Show Only AI Responses" / "Show Only Each Input and Final Response" / "Reverse Display Order" / label filter
- Refresh reloads only the selected session
- Clear resets the entire state of the right pane
  - Display filters
  - Detail keyword input and Filter / Search state
  - Selection mode and selected events
  - Anchor selection mode, anchor point, and before/after anchor display state
  - Any open label picker
- "Copy Session Resume Command" copies codex resume <session ID>
- "Copy Displayed Messages" copies all currently displayed message items
- Session label display and "Add Label to Session"
- Label display / add / remove for each event
- Each message event has its own Copy button
Right pane search and selection
- Detail keywords separate Filter and Search
  - Filter: shows only events that contain the keyword
  - Search: highlights matches and lets you move with Previous / Next
  - Hit count is shown as current / total
  - Clear Search: clears the input field, filter, and search state together
- Detail keyword matching is literal substring matching, not AND/OR parsing
- Search targets are message, function_call, function_output, and agent_update
- Pressing Enter in the search field starts a search, then releases focus so you can move with N / P
- Event Start DateTime / Event End DateTime can narrow the event timeline shown in the right pane
- Right-pane event date-time filters also use separate date + time inputs, and the time field is enabled after a date is entered
- In Selection Mode, you can check events individually and copy them together with Copy Selected
  - Even when a filter is applied, events that were already selected remain selected
- Show Only Selected Events filters the view down to selected events only
- In Anchor Selection Mode, you can choose a single message and filter with Show Only After Anchor / Show Only Before Anchor
Event display
- message (user / assistant / developer)
- user uses a light blue background, while execution context such as AGENTS.md and environment_context uses a gray background
- function_call / function_output
- agent_update
Label management
- Opens in a separate window from the Label Management button in the upper-right corner
- Shares the same language setting as the main window
- Manages session labels and event labels together
- Label colors can be entered directly as #hex, rgb(...), or oklch(...), or selected from preset colors
- Label-addition UIs also show candidates with their colors applied
Cost view

Notes

On Windows, wsl.exe -l -q is used to enumerate WSL distributions, and sessions under each distro's home directory are scanned for Copilot / VS Code Server data.
To handle large logs, the list is limited to 300 items and events are limited to 2000 items.
By default, the viewer listens on localhost only (127.0.0.1).
