• Scanned PDFs may require text recognition to be completed first.
• Complex tables, formulas, and page headers/footers require careful review.
• The membership quota is calculated based on the number of words translated, rather than the number of files.
• Before uploading sensitive documents, it is necessary to verify the cloud processing requirements.

• Keep the original text and its translation side by side for reading.
• Select the text to view the translation quickly.
• Members can use the web translation service unlimited times.
• Some login pages, script pages, or restricted pages may fail.

Voice and video translation is charged per minute, with different members receiving varying amounts of usage per 30 days.

• SVIP provides 180 minutes every 30 days.
• The reference rate for additional time is 0.3 yuan per minute.

• Keep the image clear and avoid reflections.
• Make sure there is a clear contrast between the text and the background.
• Removing irrelevant areas can improve recognition efficiency.
• Handwritten text and decorative fonts may lead to recognition errors.
• IDs and personal photos should not be uploaded casually.

Voice translation and simultaneous interpretation

The privacy policy states that voice content is processed in real time and the results are returned, without any related voice information being stored.

• A quiet environment helps improve recognition accuracy.
• Speak at a moderate pace and reduce overlapping speech among multiple people.
• Names, numbers, and technical terms need to be confirmed again.

• Establish fixed translations for brands, products, and organizations.
• Specify whether to retain the original abbreviations.
• Distinguish between the tone intended for internal and external readers.
• Regularly clean up conflicting or expired terms.

• First, verify whether the document parsing is complete.
• Try to specify the issue as precisely as possible in terms of chapter, subject, or time.

Comparison between Regular Version, VIP, and SVIP

As of August 30, 2026, the official frontend and documentation highlight the following key benefits.

The amount displayed on the member page varies depending on the duration, channel, and ongoing promotions; the amount shown on the settlement page after logging in should be taken as the reference before making a purchase.

Member prices and purchase duration

The member center offers VIP and SVIP tiers, with options for monthly, quarterly, annual subscriptions as well as subscriptions with a fixed duration.

On public pages where users are not logged in, the current unified amount is not displayed consistently; therefore, expired prices are not used.

• First, compare the number of documents required for VIP and SVIP.
• Confirm whether it belongs to the auto-renewal plan.
• The prices on the App Store and on web-based payment platforms may differ.
• Coupons and new user promotions may change the actual amount to be paid.
• Check the account number, membership level, and expiration date before making the payment.

Quota refresh rules

The monthly membership quota is typically updated every 30 days starting from the date of activation, and any unused quota does not carry over.

• Monthly, three-month, and six-month memberships are renewed on a 30-day cycle.
• After purchasing an annual membership, it is usually refreshed for the first time on the 5th day.
• After becoming an annual member, the renewal is also done every 30 days.
• Renewing a membership of the same tier only extends the duration; it does not immediately increase the credit limit.
• Upgrading from VIP to SVIP allows for an immediate update according to the SVIP quota.
• The remaining credit after the membership expires cannot be used any longer.

Extra volume packages and overage billing

For documents, videos, and AI Q&A services, additional packages can be purchased when the available quota is insufficient.

Chinese and Japanese are counted character by character, English is counted word by word; punctuation marks may also be included in the character limit.

Refunds and handling of incorrect purchases

According to the official assistance guidelines, if a refund is requested due to personal reasons such as selecting the wrong account, service, or duration, no refund will be given, nor will the service be changed or any difference in price refunded.

• Logging in with a phone number and logging in via WeChat may correspond to two separate accounts.
• Check your account ID in the personal center before making a payment.
• Confirm whether the purchase is for VIP or SVIP.
• Confirm whether you are purchasing a membership or an additional package.
• To disable auto-renewal, you need to go to the corresponding payment channel.

Invoice rules

The invoice for online top-ups must be requested within three months after the top-up is made, and it is usually issued within five working days.

• When applying, it is necessary to provide account details and payment order information.
• You can apply for regular invoices, special invoices, or electronic regular invoices.

Difference between ColorCloud Mini Translator members and translation APIs

• Members use it for the translation features in the App, Web, and plugins.
• APIs are used for third-party software and developer systems to connect.
• The amount spent by members cannot be converted directly into API balance.
• An API requires a separate request for a Token on the open platform.
• The password for membership cannot be used as the key required by third-party tools.

Caiyun Translation API

The Caiyun Translation API is available for both commercial and non-commercial applications; it is necessary to register on the open platform and comply with the requirements regarding source attribution.

The open platform protocol specifies that non-commercial developers can obtain a free quota after going through verification.

• The free quota is 1 million characters.
• The validity period for free characters is one month.
• Calls will be suspended once the balance is exhausted.
• The excess price is determined based on the real-time page of the API console.
• The application must indicate the source of the translation service in accordance with the agreement.
• Before going live officially, it is necessary to protect the Token and set call limits.

Open-source status

As of the time of verification, no official open-source repository for the complete ColorCloud Mini Translator product was found.

Scripts on GitHub, third-party clients, and API integration projects do not represent open-source versions of official products.

• Making an API available publicly does not mean making the server source code public as well.
• Browser scripts may use unofficial interfaces.
• The stability and privacy of third-party tools need to be assessed separately.
• Developers should give priority to using official open-platform tokens.

Privacy and data processing

The platform processes text, documents, images, audio, device information, and operation logs based on its functions.

• Account login may involve processing phone numbers or information from third-party accounts.
• To translate a document, it is necessary to read the content of the file uploaded by the user.
• Photo translation requires a camera or access to images.
• Voice translation requires microphone permissions.

How to protect translation materials

• First, delete the ID number, password, and internal contact information.
• When a confidentiality agreement is involved, first confirm the permission for cloud processing.
• Only the device permissions necessary to carry out the current function are granted.
• After using a public computer, log out of the account and clear the records.
• For important translations, the original local text and the revised version are retained.

Is the translation reliable?

Machine translation may misinterpret context, pronoun reference, technical terms, and cultural expressions.

• Numbers, dates, units, and negative words must be checked.
• Legal, medical, and contractual content should be reviewed by professionals.
• A terminology database can only assist with standardization; it cannot guarantee the correctness of the context.
