HiFiles is an AI document assistant from Typing AI Biometrics, positioned as a “Files Chat / Ask Docs” product. After uploading files, users can ask questions about documents in natural language, extract key information, and work with multiple files within the same chat session. It also supports embedding an AI chatbot into a website or app for document-based Q&A aimed at visitors.
According to the official site, its chatbot uses ChatGPT, and it also mentions Pinecone and LangChain for other purposes. In terms of file support, it works with PDF, TXT, PPT, CSV/XLS/XLSX, EPUB, DOC/DOCX, HTML, LaTeX/TEX, and more, giving it fairly broad coverage. Two search modes are especially useful: Vector Search focuses more on similarity matching, while Semantic Search emphasizes understanding meaning and user intent. Users can also switch between strict file mode and general knowledge mode. Strict mode answers only based on uploaded files, which is useful for compliance, legal, research, and similar scenarios; general mode is better for explanation and broader reasoning.
HiFiles offers three tiers: Free, Standard, and Premium. Free costs $0/month, and the page says it supports around 0.33 Million uploaded words, or about 13 files of 100 pages each. Standard costs $20/month, while Premium costs $30/month, with higher upload and conversation limits, embedded widgets, and customization features. One thing to note: the scraped pricing page shows several display issues, such as “0 tokens” and “NaN% OFF.” Annual discounts and exact quotas should be verified again before paying.
The main advantage is a clear onboarding flow: upload files, ask questions, export chat history, and optionally embed it on a website. Multi-file conversations and source tracking are also practical for information-heavy work. The downside is limited disclosure: it does not specify the exact ChatGPT version, Chinese-language performance, API documentation, data retention period, or whether uploaded data is used for training. The pricing page also contains display errors. On privacy, it claims encryption, access limited to the uploader, and provides a GDPR policy link, but the main content lacks more detailed enterprise-grade compliance information.
HiFiles is suitable for students, researchers, legal consultants, project managers, and small to midsize teams that want to embed a document knowledge base into a website. Access from mainland China is not mentioned in the main content, so it is considered unknown; payment methods are also not disclosed. If access or payment is restricted, alternatives to consider include ChatPDF, AskYourPDF, ChatDOC, or self-hosted options such as Dify, FastGPT, and AnythingLLM.
