koto 0.1.0

Copy a session to another agent. Keep the context.

• Added local Claude Desktop Code sessions, ordinary Cursor Desktop and CLI, WorkBuddy (China and international), and ZCode.
• Browse multiple session directories and recognized accounts. Choose the destination directory and, where supported, account when copying.
• Copy whole sessions or selected messages and attachments. Compare sessions with a tree and diff.
• Faster startup and progressive loading, with automatic index rebuilding when the format changes.
• Check and install updates from the App or CLI. Update checks include beta releases and never downgrade a newer installed version.

For conversational CLI use, the Agent must have terminal access and call koto. If it does not discover the command, ask it to run koto --help first. No Skill is required.

App and CLI are separate downloads for macOS, Windows, and Linux, on ARM64 and x64. macOS uses DMG; Windows uses a portable EXE; Linux provides a binary and DEB. SHA-256 checksums are in SHA256SUMS.

Install only the CLI:

curl -fsSL https://kotoai.site/install.sh | sh

Windows PowerShell:

irm https://kotoai.site/install.ps1 | iex

macOS packages are ad-hoc signed without notarization. Windows executables are unsigned and require WebView2. Linux requires GTK3 and WebKitGTK 4.1.

If a copied Code session is missing from Claude Desktop, restart the app to refresh its list. Existing local Cowork logs can be copied out; new Cowork tasks and cloud Chat history are not supported. On Windows ARM, use OpenCode 1.19.3's official x64 build; its ARM terminal interface does not start. Attachment handling and native-format limits are documented in Compatibility.

koto 0.1.0-beta.2

Switch agents. Keep talking.

• Added OpenCode session copying and comparison.
• Added portable Windows apps for ARM64 and x64.
• App and CLI are now separate downloads on macOS, Linux, and Windows.
• Fixed continuation commands for custom session folders and DeepSeek Harness, and OpenCode’s imported-session model selection.
• Fixed Windows/Linux appearance settings, Windows window sizing, native keyboard hints, Claude Code message ordering, and cleanup of Codex background processes.

Choose an App download for the desktop interface, or a koto-cli-* download for the standalone CLI. No Skill installation is required. Checksums are in SHA256SUMS.

macOS apps use DMG; Windows apps use EXE; Linux apps are available as a binary or DEB. macOS packages are ad-hoc signed without notarization. Linux requires GTK3 and WebKitGTK 4.1. Windows executables are unsigned, use WebView2, and prompt if the runtime is missing.

OpenCode 1.19.3’s Windows ARM TUI currently fails to start. Its official x64 build works under Windows ARM emulation and was tested for session continuation.

koto 0.1.0-beta.1

Switch agents. Keep talking.

Copy conversations or selected messages between agents. Compare sessions with a tree or diff. The bundled koto CLI lets your Agent copy the current conversation and return a continuation command, without a separate Skill.

This first beta includes the app and CLI for macOS (Apple silicon / Intel) and Linux (ARM64 / x86_64). Windows is not included.

Use the matching DMG on macOS. On compatible Debian/Ubuntu systems use the DEB; portable tar.gz packages are also available. Checksums are in SHA256SUMS.

macOS packages are ad-hoc signed, without Apple notarization. Linux requires glibc 2.36+, GTK3 and WebKitGTK 4.1.
