About This Software

Typewriter dialogue for VTubers

Type a line, press Enter, and NanaType reveals it on your stream one character at a time in an AVG / RPG-style dialogue box. Everything you say is also kept in a live-chat style history with avatar, name and speech bubble.

Features

• Display box – a transparent overlay with typewriter reveal, per-character effects, pauses, page turns, screen shake and character portrait variants.
  
• Input window – edit directly inside a live skin preview, with rich text (bold, colour, outline, ruby, effects, pacing) or a markup source mode. Line breaks in the editor match the display exactly.
  
• Two input modes – "Edit then send" plays the line at typewriter pace; "Live mirror" follows your typing in real time.
  
• History window – avatar + name + bubble chat list that appears as you type.
  
• 28 built-in skins – Love Letter, Sonnet, Crayon, Night, Parchment, Classic ADV, RPG Window, Pixel Handheld, Terminal, Ink, Sakura, Gothic Rose, Starlit Magic, Forest Spirit, Tidal Aquarium and more. Import / export .ntpkg packages with hot reload.
  
• Steam Workshop – browse and subscribe to skins and sound packs from inside the app.
  
• OBS ready – Spout2 (Windows) or Syphon (macOS) share the GPU texture directly, and keep sending even when the window is hidden. Window capture works too.
  
• Co-op on Steam – up to 8 people in one room. Your own lines stay in your display box, a partner window shows everyone else's lines live, and the shared history keeps what everyone has sent.
  
• VTube Studio, OSC and WebSocket – trigger expressions, hotkeys, parameters and lip sync exactly where they appear in the line.
  
• Chat – read Twitch chat and, after signing in, send your lines to your Twitch channel. Third-party chat through blivechat (open-platform code) and the 彗星号 (Comet) plugin, with @mentions and replies.
  
• Stickers – add your own image folders or Echo-Live emoji sets; animated stickers play in the display, history and OBS output.
  
• Plugins – sandboxed Lua / Wasm feature plugins with no network or file access, and restricted WGSL effects for advanced skins.
  
• Global hotkeys and tray – F8 brings up the input box, F9 continues; lock overlays to click through them.
  
• Languages – English, 简体中文, 日本語.
