SpeedReaderRust

RSVP (Rapid Serial Visual Presentation) reading overlay. Displays text word by word with highlighted center letter (ORP). Press Space to pause and jump to the exact reading position in the editor. I use this application for fast reading of SDD.

Install

cargo install speed-reader

Or from source:

git clone https://github.com/bimawa/SpeedReaderRust
cd SpeedReaderRust
cargo install --path gui

Usage in Zed

1. Add task (global)

Add to ~/.config/zed/tasks.json:

[
  {
    "label": "SpeedReader: Read current file",
    "command": "speed-reader",
    "args": ["$ZED_FILE"],
    "tags": ["speed-reader"],
    "hide": "on_success"
  }
]

2. Run

Cmd+Shift+P → SpeedReader: Read current file

3. Keybinding (optional)

Add to ~/.config/zed/keybindings.json:

{
  "context": "Editor",
  "bindings": {
    "cmd-shift-r": ["task::Spawn", { "task_name": "SpeedReader: Read current file" }]
  }
}

Then Cmd+Shift+R from any buffer.

4. Read buffer (pbpaste)

Launch the reader with selected text instead of the full file:

Add a second task to ~/.config/zed/tasks.json:

[
  {
    "label": "SpeedReader: Read current file",
    "command": "speed-reader",
    "args": ["$ZED_FILE"],
    "tags": ["speed-reader"],
    "hide": "on_success"
  },
  {
    "label": "SpeedReader: Read buffer",
    "command": "bash",
    "args": ["-c", "pbpaste | speed-reader"],
    "tags": ["speed-reader"],
    "hide": "on_success"
  }
]

Usage:

1. Select text in the editor.
2. Cmd+C to copy selection to clipboard.
3. Cmd+Shift+P → SpeedReader: Read buffer.

Or add a keybinding in ~/.config/zed/keybindings.json:

{
  "context": "Editor",
  "bindings": {
    "cmd-shift-t": ["task::Spawn", { "task_name": "SpeedReader: Read buffer" }]
  }
}

Then select text, copy, and press Cmd+Shift+T.

Configure editor (not just Zed)

Edit ~/.config/speed-reader/config.json:

{
  "editor_cmd": "code",
  "wpm": 300
}

Supports any editor with editor file:line:col CLI syntax (Zed, VS Code, Vim, Helix, etc.).
