Three one-minute clips recorded from the app.

The clips have no audio and are captioned. They use sample data.

1

Connects directly to Twitch

You sign in once with your Twitch account. LuckyBot receives your channel's events from Twitch and plays the matching alert. That covers follows, subs, gift subs, bits, raids, channel point redemptions, hype trains, polls, and predictions.

2

Runs on your PC

The app includes its own local server and database, and your overlays are served from your PC. Your data is backed up on a schedule and before every update.

Many tools in one app

Alert overlays, combined chat, a chatbot, a subathon timer, channel point rewards, polls and predictions, stats and goals, moderation, and OBS control are all in the same window. They share the same events, media library, and stats.

Alert overlays

A visual alert editor and a code editor.

The visual editor has layers, shapes, motion paths, and keyframe timelines. Each alert can have variants, for example a different alert for tier 3 subs or for raids of 100 viewers or more.

  • Each alert can have its own text-to-speech, queue, and chance of playing
  • The starter pack adds a full set of alerts in one click
  • Advanced overlays are written in HTML, CSS, and JavaScript with a live preview
  • StreamElements overlays and AlertBox setups can be imported with their media

Reactive overlays

An on-screen character that reacts to events.

The character loops an idle animation. Each event type can have its own keyframed reaction, such as a wave on a follow. Layers can be attached to each other and can follow a path you draw.

Chat

A chat client with moderation tools.

Chat shows badges, third-party emotes, replies, and event cards. It can translate messages and highlight first-time chatters.

  • Channels you moderate open in tabs
  • Chat can be docked inside OBS
  • The chat overlay for your stream updates as you change its style

Combined chat

Twitch, YouTube, and TikTok LIVE chat in one window.

If you stream to more than one platform, LuckyBot shows the chats together in one list. Each message is tagged TW, YT, or TT.

  • YouTube chat comes in through Streamer.bot. Super Chats, Super Stickers, and memberships show as cards.
  • TikTok LIVE chat comes in through TikFinity Desktop, which is free. Gifts, follows, subscribes, and shares show as cards.
  • YouTube and TikTok events can trigger your alert overlays.
  • The combined chat also shows in the chat popout, the OBS dock, and the chat overlay on stream.
  • Messages you send from LuckyBot go to Twitch chat. YouTube and TikTok chat are read-only.

Popout windows

Chat and the activity feed open in their own windows.

Each popout is a separate window you can put on another monitor. The activity feed lists follows, subs, bits, raids, and channel point redemptions as they arrive.

  • The chat popout has the same moderation and stream buttons as the main chat
  • The activity feed has buttons to pause alerts, skip an alert, and mute text-to-speech
  • Both can also be added to OBS as docks

Chatbot

A chatbot with commands, timers, and a currency.

Commands are built from more than thirty action steps. Steps can check conditions, fetch a URL, control OBS, Spotify, or Lumia lights, press keys, and play sounds.

  • Tracks watch time and runs a currency with a shop and casino games
  • Includes a builder for your own chat minigames
  • Imports commands, timers, quotes, and balances from Firebot, StreamElements, Nightbot, Streamlabs, and Mix It Up
  • Commands can also run on events such as subs, raids, and cheers
  • Posts from your account or a separate bot account, and keeps running with the window closed

Subathons

A subathon timer that runs in the app.

The timer is kept by the app, so reloading or restarting OBS does not change it. You set how much time each event and sub tier adds.

  • Happy-hour multipliers and milestone goals
  • A log of every time grant, with undo
  • Timer and goals overlays are included

  • Channel point rewards with a redemption queue
  • Unban requests and blocked terms

What it can replace

LuckyBot also works alongside Streamer.bot and cloud relays. If the same event arrives from more than one source, the alert plays once.

Alert box services

Alert overlays are served from your PC to an OBS browser source.

Chat clients, multichat tools, and cloud bots

Twitch, YouTube, and TikTok chat are in one window with the chatbot. You send and moderate Twitch chat from it.

Subathon timers and stats trackers

The timer, goals, and stream counters can be shown in any overlay.
