What is Dola AI? How to use ByteDance's AI assistant in 2026

AI assistants have become everyday work tools rather than something people try out for curiosity. According to Microsoft, 75% of knowledge workers were using AI at work by 2024. Amid this wave, what is Dola AI, and how is it different from familiar AI assistants? This article will help you understand what Dola AI is, what it can do, and how to use it for chatting, writing, and translation. You can also explore Aniday’s AI app library for comparison.

What is Dola AI?

Dola AI is a multifunctional AI assistant developed by ByteDance that allows users to chat, create content, translate text, summarize documents, generate images, and ask questions across a wide range of topics. The app is available on iOS, Android, Windows, and the web, supports 19 languages including Vietnamese, and follows a freemium model with optional in-app upgrades. As a product from the same company behind TikTok, it is backed by a major technology corporation.

Dola AI is not an entirely new product. It was originally launched in August 2023 under the name Cici before being rebranded as Dola on November 3, 2025. Within Aniday’s ecosystem, it belongs to the category of AI virtual assistants designed to support everyday productivity.

Who developed Dola AI and how is it related to Doubao?

Dola AI was developed by ByteDance, the parent company of TikTok, and is built on the same underlying AI model family as Doubao, ByteDance’s domestic AI assistant in China. This connection matters because it shows that Dola is powered by a model already tested at massive scale. According to TechNode, Doubao surpassed 100 million daily active users by the end of 2025. Dola serves as the international-facing version of this product line.

What is Dola AI used for?

Dola AI can be used for question-and-answer conversations, writing and editing text, translation, summarizing long-form content, generating images, and coding assistance. You can ask it to draft emails, create job descriptions, summarize reports, or explain code snippets. It functions as a versatile AI assistant that combines multiple capabilities into a single platform.

Can Dola AI chat with PDFs and files?

Yes, Dola AI can read uploaded documents and answer questions based on their content, including PDF files. You can upload a lengthy document, ask for key takeaways, or request section-by-section summaries, and the app will provide responses grounded in the uploaded material. This feature is particularly useful for people who regularly work with contracts, reports, or research documents.

Does Dola AI support Vietnamese?

Yes, Dola AI supports Vietnamese as one of its 19 supported languages. Vietnamese users can chat, write, and translate directly in their native language, making it more accessible than assistants that primarily focus on English. Its translation capabilities between Vietnamese and other languages also make it a convenient option among AI translation and summarization tools. For formal documents such as contracts or legal materials, however, human review is still recommended before use.

How to use Dola AI for chatting, writing, and translation

The core workflow consists of four steps: installing the app, providing instructions, refining the output, and reviewing the results before using them. This process applies to chatting, writing, and translation tasks and can easily fit into your existing productivity workflow.

Step 1: Download the app and sign in

Download Dola AI on iOS, Android, Windows, or access it through the web version. Sign in and check whether the app is available in your region before installation.

Step 2: Chat or assign a writing task

Enter a question for conversation or clearly describe the writing task, including context, audience, and desired length. The more specific your prompt is, the more accurate and useful the response will be.

Step 3: Translate and refine

Paste the text you want translated, choose the target language, and ask the AI to adjust tone or style if needed. You can continue the conversation to refine specific wording instead of translating the entire text again.

Step 4: Review before using

Always review the output before sending or publishing it, especially when it contains numbers, proper names, or important translations. AI assistants can occasionally present incorrect information with a high degree of confidence, making verification an essential step.

Is Dola AI available on both mobile and desktop?

Yes, Dola AI supports multiple platforms, including iOS, Android, Windows, and the web, allowing seamless use across smartphones and computers. One important consideration is regional availability. The app is restricted in certain markets, including the United States, Canada, Australia, and China. Before installing it, check whether it is officially available in your location.

Is Dola AI free?

Dola AI offers a free tier with optional in-app subscription plans that unlock additional usage capacity and advanced features. The free version is sufficient for most everyday chatting, writing, and translation tasks. For heavier professional use, a paid plan may be more suitable. Always check the latest pricing information directly within the app before subscribing.

How is Dola AI different from Cici and Doubao?

Dola, Cici, and Doubao are different names within the same ByteDance product family, distinguished mainly by branding and target markets. Cici was the former name of Dola before the rebrand in November 2025. Doubao is the China-focused version and has already achieved massive user adoption. Understanding this relationship helps clarify that Dola is not a completely new product but rather the international version of a well-established AI assistant ecosystem.

Learning how to effectively use an AI assistant like Dola is increasingly becoming a valuable professional skill. According to Microsoft, workers increasingly expect AI to handle repetitive tasks such as drafting and summarizing, making proficiency with these tools a practical workplace advantage. You may also explore career development resources to maximize these skills.

Conclusion

Dola AI is ByteDance’s multifunctional AI assistant, formerly known as Cici, designed for chatting, writing, translation, and document summarization. It supports Vietnamese and works across both mobile and desktop platforms. The key things to remember are regional availability restrictions and the importance of reviewing AI-generated outputs before using them. When used effectively, Dola AI can save hours of work every week.
