Main functions

• Intelligent dialogue: Multi-round dialogue based on a large language model, supporting role setting and system prompt word customization. Suitable for daily consultation, brainstorming, text polishing and other scenarios. Conversations support contextual references and memory recall to avoid repeated input of background information.
• Multi-modal file understanding: Supports uploading pictures (JPG/PNG), PDF, Word, Excel, TXT, Markdown and other format files. AI automatically extracts and understands the file content, and can perform question and answer, summary and information extraction based on the file content. Excel files support table-level Q&A and multidimensional perspective analysis.
• Automatic generation of weekly reports: Automatically generate a structured weekly report based on the user's conversation records and document operations this week. Supports template customization (Markdown/HTML), data cycle selection (weekly/biweekly/monthly) and export format settings. Reduce weekly report writing time from tens of minutes to minutes.
• Long-term memory: AI stores user information (project background, personal preferences, completed items) in three dimensions: entities, relationships, and timelines, and automatically references it in subsequent conversations. Supports manual editing and deletion of memory entries to ensure users have control over their data.
• Personal Knowledge Base: Import documents, notes, and web content to build a knowledge base, and AI automatically retrieves relevant knowledge during conversations. Supports folder-level batch import, manual annotation of priorities and knowledge base search. The knowledge base capacity is 5GB for the Pro version and 500MB for the free version.
• Team Collaboration Space: Create a workspace, invite members to join, and share knowledge base and conversation history. Members can collaboratively edit documents, comment and communicate in the space. Suitable for project information management of small teams (2~20 people).
• Cross-device synchronization: All conversations, knowledge bases and settings are automatically synchronized to all logged-in devices (Web/iOS/Android), and the data created on the desktop can be accessed on the mobile phone at any time.
• Markdown Export: Conversation content and knowledge base entries can

One-click export to Markdown or PDF for easy backup and external use.

Model and version evolution

Version	Release Date	Key Changes
v2.3	2026-06	Weekly report template engine, knowledge base folder-level import, memory retrieval optimization
v2.2	2026-04	Multi-modal file understanding, conversation history search, Markdown export
v2.1	2026-02	Long-term memory online, personal knowledge base Alpha, cross-device synchronization
v2.0	2025-11	Major product reconstruction: new UI, team collaboration space, API openness, multi-language support
v1.0	2025-03	First release: Intelligent dialogue and basic file summary

From v1.0 to v2.3, Fruit AI has a clear evolution path: v1 verifies the basic scenario of dialogue + file summary, v2.0 achieves platform transformation (team collaboration + multi-language) through architectural reconstruction, and subsequent versions successively complete differentiated functions such as memory, knowledge base, and weekly reports. Version records are subject to the official changelog.

Technical advantages

• Hybrid model architecture: Dynamically route to the most suitable underlying model (self-developed + third-party large model) based on task type (conversation, document understanding, summary generation), ensuring quality while controlling inference costs. Document understanding tasks are routed to multi-modal models, and conversation tasks are routed to more cost-effective plain text models.
• Progressive Context Management: Through a hierarchical context compression strategy, high-density information retention is achieved within approximately 128K context windows. Key information (user settings, project background) is retained first, and secondary information (chat, repetition) is compressed regularly, taking into account the coherence and response speed of long conversations.
• Hybrid retrieval of knowledge base: Combines vector retrieval (Embedding) and keyword retrieval (BM25) to conduct hybrid recall of user knowledge base. Vector retrieval is responsible for semantic matching, and BM25 is responsible for exact matching. The combination of the two improves the recall rate of low-resource languages ​​and fuzzy queries.
• Structured Memory System: User information is stored and indexed three-dimensionally by entities (people/projects/documents), relationships (associations, dependencies), and timelines (creation/modification time), supporting precise retrieval and reference across sessions. The memory system supports manual management by users, who can view, edit and delete memory entries.
• End-to-End Encryption: All data transmission (TLS 1.3) and storage (AES-256) encrypted. The team version supports administrator rights audit logs to record members’ operating behaviors.

Application scenarios

• Personal Knowledge Management: Freelancers, researchers or writers can import the documents, papers and work records they read daily into the knowledge base, and directly ask AI questions when they need information. Compared with the traditional folder retrieval method, knowledge base + AI Q&A can shorten the time of single information location from 3-5 minutes to 10-30 seconds.
• Team Weekly Report Automation: Small teams enable the weekly report generator, and AI automatically summarizes each member's work content and key results for the week. Managers only need to review the tweaks before issuing them. Verification method: Compare the average time taken to write weekly reports in each of the four weeks before and after activation to confirm the efficiency improvement.
• Document review and information extraction: Upload PDF/Word documents such as contracts, reports, papers, etc., and AI will automatically extract key information (date, amount, decision, to-do) and generate a structured summary. Verification method: Manually review the accuracy of key fields extracted by AI. It is recommended to conduct sampling verification on document types used for the first time.
• Cross-language communication assistance: Supports dialogue and document understanding in three languages: Chinese, English, and Japanese. Non-native users can read foreign language documents in their native language, and AI provides translation and interpretation. Restrictions: The translation quality may be biased in terminology in professional fields (law, medicine), and is not recommended for formal translation scenarios.
• Project Information Center: Small teams gather project documents, meeting minutes and communication records into the team space. After new members join, they can quickly query the project background and decision-making records through AI. Verification method: Simulate the onboarding scenario of new members and test the accuracy and completeness of the AI's answer to project history questions.
