AUDOIR

What is AUDOIR?

AUDOIR is a portal for AI applications and technical tutorials, operated by Audoir, LLC; it is not a single efficiency tool. The official website currently showcases four AI applications designed for personal use, job hunting, and language learning, along with practical tutorials for developers.

Audoir, LLC was founded in 2016; its official website states that the team is located in the San Francisco Bay Area. Users should choose the appropriate sub-product based on their specific needs, as accounts, functions, data, and pricing methods may be independent of one another.

AUDOIR’s current AI applications

Reflection: AI Diary

Reflexion is designed for personal reflection and journaling; it can analyze the content entered by users, provide encouragement and personalized insights, and allow users to converse with an AI assistant that understands the context of the journal entries. It should not serve as a substitute for psychotherapy, crisis intervention, or professional medical advice.

Resunet: AI resumes and cover letters

Resunet analyzes job descriptions and company information, then creates customized resumes and cover letters based on the user’s original resume. The user still needs to check the experiences, skills, dates, and achievements to avoid submitting false information to employers.

Youhan: Personalized Chinese learning

Youhan assists users in learning Chinese through adaptive flashcards, contextual example sentences, and audio recordings of phrases. The system adjusts the difficulty level of the vocabulary based on the user’s responses, but it is still recommended to have teachers or native speakers check the pronunciation and the AI-generated example sentences.

Vowels: AI language conversations

Vocali uses AI-powered voice conversations to simulate real-life communication scenarios, and it incorporates spaced repetition to aid in vocabulary retention. The languages available currently are English, Spanish, Mandarin, French, German, Japanese, Arabic, Portuguese, Russian, Korean, and Hindi.

AUDOIR Technical Tutorial

The official website also provides practical articles and sample projects for developers. Tutorials are not equivalent to hosting services; readers usually need to set up their own development environment, obtain third-party accounts, and cover the costs associated with relevant APIs.

AI Agent

• Use Next.js and the Vercel AI SDK to create streaming chat and structured outputs.
• From basic chatbots to LangGraph, MCP, and database tools.
• It introduces multi-agent systems, observability, evaluation, data pipelines, and manual review.
• It covers long-term memory, group collaboration, checkpoints, and time reversal.

DevOps and system design

• Kubernetes: from local clusters to cloud-based production deployments.
• GitHub Actions events, workflows, and continuous integration practices.
• Comparison of REST, GraphQL, and gRPC communication patterns.
• WebSocket, WebRTC, and real-time speech transcription.
• Usage patterns of Kafka, RabbitMQ, SQS, SNS, and Redis.

Full-stack and testing

• Interfaces are built using Next.js, Express, NestJS, Flask, and FastAPI.
• Performance handling for infinite scrolling and virtual lists in React.
• Testing workflows for Jest, React Testing Library, Playwright, and Cypress.

How to use AUDOIR

1. First, determine whether you need a personal diary, job application materials, Chinese language learning resources, voice conversation tools, or development tutorials.
2. Access the corresponding application through the AUDOIR portal, and review that application’s own privacy and terms of use.
3. Use a free trial or a small amount of credits to test the core processes; do not submit large amounts of data at once.
4. Before uploading diaries, resumes, or audio files, remove any unnecessary identity, customer, and account information.
5. Manually verify the AI-generated experiences, example sentences, pronunciations, analyses, and suggestions.
6. When learning to develop, understand the concepts through the relevant tutorials and work on the accompanying example projects.
7. Before running the sample code, check the dependencies, environment variables, API keys, and security settings.
8. Add authentication, permissions, logging, monitoring, and error handling before production use.

Usage restrictions and precautions

• AUDOIR is a portfolio portal; there is no single account or set of guidelines that applies to all applications.
• The data types, storage strategies, and pricing methods for different sub-products need to be checked separately.
• AI-powered diary analysis cannot replace psychological counseling, diagnosis, or emergency assistance.
• The content of the resume must be accurate; errors and exaggerations can affect credibility in job applications.
• Language learning materials may contain issues related to pronunciation, grammar, and context.
• The tutorial examples are intended for educational purposes and cannot be deployed in production without going through security reviews.
• The cloud services, models, and third-party APIs used in the examples may incur separate charges.
• Old music and lyric creation apps are no longer supported, and should not be recommended as core features anymore.

AUDOIR price

As of August 26, 2026, the AUDOIR official website does not provide a unified membership plan or overall price. The four applications are operated separately; the public pages indicate whether a trial version is available or what the pricing structure is, but there is not enough information to create a reliable list of prices for different subscription plans.

• Reflection: The current portal provides access to the application, but no explicit price is available on the public page.
• Resunet: The official website offers a free trial option; the specific amount of free usage and the pricing for paid services have not yet been made public.
• Youhan: The official website offers a free trial option; the specific packages and quotas are not yet available publicly.
• Vocali: It offers a free trial and allows points to be purchased on demand; the amount of points available for purchase is not displayed on the public page.
• Technical tutorials: Articles on the official website can be read directly; readers are responsible for any costs associated with third-party models, cloud services, and deployment.

Prices, trial quotas, and payment methods by region may change as the application is updated. It is necessary to refer to the purchase page specific to each sub-product or the real-time information available in the app store before making a purchase.

Old applications that are no longer supported have been discontinued.

The official website now states clearly that Melodea, Lyricai, Quick Lyrics AI, Rhyme Lines AI, AI Lyrics Assistant, Lyrics to Music AI, AI Music Magic, and AI Music Builder are no longer supported. The music and lyrics features included in previous evaluations can no longer be part of AUDOIR’s current product lineup.

Some old product pages, terms, or historical information are still accessible on the website, but this does not mean that the services are still being maintained. Users should not store important data in these old applications or rely on their availability.

Data and Privacy

The latest update to AUDOIR’s general privacy policy was made on June 12, 2026. The company may collect contact information, account credentials, usage data, IP addresses, browser types, and device identifiers, and use this information for the operation of its services, their improvement, sending notifications, as well as to ensure security and compliance with legal requirements.

The policy states that encrypted methods are to be used for transmitting and storing static data, and access to personal information is restricted; however, it does not specify the exact retention period for all contents within each application. When diaries, resumes, voice recordings, and learning records contain sensitive information, it is necessary to consult the policies specific to those sub-products and limit the amount of data that is uploaded.

Is AUDOIR open source?

Reflexion, Resunet, Youhan, and Vocali are not listed on their official websites as open-source applications; therefore, they should be considered closed-source online services. Audoir has made some example repositories available on GitHub alongside tutorials, but these codes do not contain the complete source code for commercial use.

When using tutorial repositories, it is necessary to check the license and dependencies of each repository separately. Public code examples do not automatically grant the right to use the AUDOIR brand, application data, or to deploy online services.
