Doudou

What is DouDou AI?

Doudou AI is a multi-modal AI companion centered around game scenarios, developed by Beijing XinYingSuiXing Technology Co., Ltd.

It plays games with users through table pets or floating balls, and offers real-time interaction via visuals, sounds, dialogue, and guides.

Main functions

• Identify game visuals in real time and understand the current scene.
• Answer strategy questions through online searches and reasoning.
• Provide proactive suggestions, celebrations, or conversation companionship in specific situations.
• Use real-time voice calls for natural conversations.
• Interact via text, key-based communication, desktop pets, or floating balls.
• Remember the conversations and shared experiences in different games.
• A review and analysis are provided after the match is over.
• Choose an original IP, a creator avatar, or a virtual streamer partner.
• Unlock stories, tasks, and topics through affinity.
• It extends to watching shows, shopping, learning, and providing companionship in daily life.

Multimodal game companionship

Identification and strategies are only supplementary information; real-time suggestions in competitive games may be delayed, inaccurate, or inappropriate for the current version.

General support and deep customization

Officials state that universal recognition covers over 90% of PC games, while the list of supported games includes more than 5,000 titles.

“Game support” does not mean that all games have the same level of depth; it is necessary to check the details page of each specific game before using it.

Selected game scenes

• Competitive games: battle analysis, equipment recommendations, and highlight celebrations.
• 3A games: Boss strategies, map breakdowns, and tips for getting stuck.
• Indie games: gameplay guidance, collection routes, and narrative support.
• Multiplayer games: Provide voice alerts or comments based on the situation.
• Post-match phase: Review the entire match and identify actions that need improvement.
• Leisure scenario: Light conversations and emotional companionship centered around the image.

Intimacy with AI companions

Partners include original characters, digital avatars of content creators, virtual streamers, and other collaborative characters, with each character having its own unique design.

AI characters are not real people, and the expressions of their collaborative counterparts should not be regarded as the actual opinions or professional advice of those individuals.

Real-time voice and intercom communication

Real-time voice is suitable for continuous chatting, while button-based communication is better suited for gaming scenarios where it is not desired to keep the microphone active all the time.

1. Verify that the microphone device and its driver are functioning properly within the system.
2. Go to the settings for Doudou and select the correct input device.
3. Use the call button with a floating ball to start real-time voice communication.
4. To use button-based intercom, press Alt+X to start recording.
5. After saying that, press Alt+X again to end and send.
6. If the device is switched mid-call, re-enter the call after hanging up.
7. If shortcut keys conflict, they can be reconfigured in the settings.

Table pets and floating balls

The floating ball may still block the game buttons; its position should be adjusted first, and it is necessary to verify that the game’s or anti-cheat rules permit the use of such a overlay.

Non-game companionship

• Watching dramas: Discussing the plot, expressing opinions, or reviewing the events.
• Shopping: Discuss products and make selections based on the current screen.
• Learning: Organizing notes, clarifying thoughts, and answering questions.
• Spoken language: Practice conversations through real-time voice communication.
• Work: Assisting with understanding and communication in the authorization screen.
• In daily life: companionship through text, voice, and long-term memory.

Suggestions for shopping, studying, and working may be incorrect; manual judgment is necessary when it comes to payments, exams, or company-related matters.

The official version notes from August 2025 state that Commo Coins and battery level have been discontinued, and they have all been replaced by the term “energy”.

Supported platforms

Screen recognition and privacy

Screen sharing on mobile devices is disabled by default; image capture only starts once the user gives explicit permission.

• Camera and album: Modify the profile picture or select an image.
• Screen sharing: Identifies games or other current visuals.
• Floating window: A minimized component that appears above the Android app.
• Storage: Save or update the necessary roles and media assets.
• Device information: used for security, crash, and performance analysis.
• Notifications and auto-start: Ensures message and content alerts.

Suggestions for privacy settings

1. Enable screen sharing only when identification is required.
2. Pause recognition before accessing payment, chat, or corporate systems.
3. Turn off the notification pop-ups to prevent private messages from appearing on the screen.
4. Give priority to using the button-based intercom to reduce the time spent listening to audio continuously.
5. Crop the account name, username, and personal information before sending the screenshot.
6. Regularly check chat records, memories, and account settings.
7. Turn off the floating window, microphone, and auto-start when they are no longer in use.

Content accuracy

• The guide may be applicable to older versions, different regions, or different modes.
• Image recognition is affected by resolution, occlusion, and special effects.
• Real-time suggestions may experience delays or misinterpret the current situation.
• Online searches may cite incorrect or unverified content.
• Character expressions do not represent the real-time opinions of the associated figures.
• Advice on consumption and health cannot replace professional judgment.

The boundaries between open data and open source

• Errors can occur in screen display, audio, and strategy recognition.
• Real-time functionality depends on the network, device performance, and system permissions.
