sivtr

sivtr turns terminal output into reusable text. Pipe output into a browser, wrap command execution, search across past captures, copy structured command blocks, or pull the last useful turn out of a Codex session without opening the transcript by hand.

It is not a terminal emulator, multiplexer, or replacement shell. It works beside the terminal you already use.

Why it exists

Terminal output is usually treated as disposable. Once a command scrolls away, the useful part is trapped in scrollback, copy mode, or a giant log. sivtr gives that output a small workspace:

• capture output from stdin, subprocesses, or shell integration;
• browse output in a Vim-style TUI;
• select character, line, or block ranges;
• copy recent command blocks by semantic selector;
• search saved output with SQLite FTS5;
• reuse Codex conversation blocks from the current project.

First command

Install from the repository, then pipe output into sivtr:

cargo install --path .
cargo test 2>&1 | sivtr

Inside the browser, use j and k to move, / to search, v or V to select, y to copy, and q to quit.

Common workflows

Goal	Command
Browse command output	cargo test 2>&1 | sivtr
Run and capture a command	sivtr run cargo test
Open the current session log	sivtr import
Copy the latest command output	sivtr copy out
Pick one or more recent blocks	sivtr copy --pick
Copy the latest assistant reply from Codex	sivtr copy codex out
Search saved captures	sivtr history search "panic"
Start the Windows Codex hotkey	sivtr hotkey start
