Solo sound

What is a solo sound?

DuyXiang is a lightweight AI companion app for taking notes; its full name is “DuyXiang – Your AI Social Circle”.

After users record their daily activities, emotions, and random thoughts, a custom AI character will participate in responding, chatting, and engaging in long-term interactions.

Main functions

• Use a private circle to document daily life, thoughts, and emotions.
• Create AI characters with names, settings, and personalities.
• Have multiple AI characters respond to the same update.
• Experience realistic chat features such as typing, undoing actions, and internal thoughts.
• Enhance goodwill and the relationship through continuous interaction.
• Receive virtual gifts offered by AI characters.
• Use white noise and an interactive switch to accompany you during sleep.
• Draw, learn, or engage in role-playing activities with the characters.
• Obtain exclusive characters or content by getting gacha toys.
• Use local and cloud backups to save records.

Light Notes and Private Circle

DuyXiang combines the styles of diaries and social media posts, but it is designed for interaction with AI characters rather than with real people on social networks.

“The fact that no real people see it” describes the social aspect of the product; it does not mean that the data is never processed by servers or through technical means.

Custom AI characters

Users can set the identity, personality, tone, relationships, and background of the character, so that the responses are closer to the desired style of interaction.

1. Determine the relationship between the character and you, as well as its core personality.
2. Specify age, experience, values, and way of speaking.
3. Add topics that the character likes, dislikes, and is reluctant to touch.
4. Provide two to three example conversations that meet the requirements.
5. It is clearly prohibited to impersonate real people or give high-risk advice.
6. First, test the stability of the character using ordinary daily conversations.
7. When a deviation is detected, adjust the settings rather than keeping adding content.
8. When real persons are involved, their names, images, and personal rights must be respected.

Simulated chatting

Companionship system

• White noise: Provides ambient sound for use while resting or falling asleep.
• Interactive switch: Controls whether the character participates in a specific accompaniment.
• Paint together: interact together around creativity and visuals.
• Learning companionship: helping to organize plans, review material, and stay consistent.

Sleep and emotional support fall under the category of entertainment and lifestyle aids; they do not possess the capability for medical diagnosis or psychological treatment.

Gifts, gashapon toys, and ringing stones

The platform offers features such as virtual gifts, gacha toys, and exclusive characters; some of these contents may require Echo Stones or membership.

• Double date: Advance the interactive story within a set scenario.
• Paint together: Create content based on the creativity of characters and users.

Free version and paid version

Duy Xiang is available for free download, with in-app purchases such as Premium, Premium Pro, and Xiang Shi.

Membership does not necessarily include all Rongshi products, and topping up Rongshi does not automatically grant membership benefits.

Member price

The prices for the App Store in China listed below were verified on August 31, 2026; prices may vary in other channels and regions.

The annual plan is cheaper than purchasing it for 12 consecutive months at the current price, but the ultimate benefits, renewal rules, and refund policies are as specified on the settlement page.

Annual membership payment comparison

The nominal savings take into account only the listed price on the page, and do not include discounts, differences between channels, taxes, or costs associated with unused services.

Price of resonant stones

The unit cost of large packages is lower, but Echo Stones are virtual currencies used within the application; therefore, one should not top up more money than is actually necessary just to take advantage of discounts.

Supported platforms

Offline and cloud data boundaries

The official website states that it supports offline use as well as dual backup on local devices and in the cloud, but the AI functions that require an internet connection still need to send inputs to the backend.

“Available offline” and “all AI processing takes place locally” are not the same concept; sensitive information should still not be entered.

AI input processing

The official privacy policy states that AI inputs are used for real-time responses only, and are not utilized for training models, creating user profiles, or any other purposes.

• The content sent includes chat messages and query texts submitted by the user voluntarily.
• The account ID, phone number, and device identifier are not sent to the AI model.
• Input is processed by the officially operated Duying text large model service.
• The original input is discarded after processing and is not stored for an extended period.
• AI input is not shared with external services such as OpenAI or Claude.
• Other accounts, backup data, and application data are still handled separately in accordance with the relevant policies.

Personalized recommendations and third-party SDKs

“Guess You Like” generates recommendations based on browsing and clicking history; users can turn it off in the settings.

• Once it is turned off, the generation of personalized recommendations based on relevant behavior data will cease.
• The push SDK may handle device identification and application status.
• Crash and Performance Services may collect diagnostic information.
• The clipboard should only be read when the user voluntarily shares it.
• Cameras and photo albums are used for profile pictures or images in notes.
• Check the latest list of third-party SDKs before installation.

Suggestions for privacy settings

1. Do not write down your ID card details, address, password, or verification code in notes.
2. Cover faces, receipts, and chat notifications before uploading images.
3. Turn off “What You Might Like” when no recommendations are needed.
4. Only grant the necessary permissions such as for the camera, album, and notifications.
5. Regularly check the status of cloud backups and cross-device synchronization.
6. Export or organize important records before disabling the role.
7. When the account is not in use, follow the application’s procedures to cancel it and confirm its deletion.
8. After the system update, read the privacy policy and permission list again.

The boundary between APIs and open source
