Sales Support App "LeanCard Sync" Achieves Major Update with LINE×Salesforce Integration. Implements "AI Assistant Function" to Navigate Sales Strategies with AI

EARLYWELL Inc. (Headquarters: Munakata City, Fukuoka Prefecture; Representative Director: Hirokazu Hayai) implemented a major update to "LeanCard Sync," a sales support application that seamlessly links LINE and Salesforce to streamline sales activities for small and medium-sized enterprises, in April 2026.

LeanCard Sync has been responsible for digitizing business cards and handling everything from customer contact to CRM integration. With this update, the latest generative AI has been fully implemented. New features include "Deep Search," which allows natural language searching of Salesforce information from LINE, "AI Company Profiling," which investigates and analyzes the latest company information with a single button click, and a "Business Card List Function" for smarter business card organization. It has evolved beyond a mere data entry tool to become an **"AI assistant that expands the thinking of inside sales and sales representatives and proposes the next actions to take."**

【Why "LINE"? The Core Concept of LeanCard Sync】

The biggest hurdle to CRM (Customer Relationship Management) adoption in sales is the "complexity of input and operation." For busy sales representatives, opening a multi-functional Salesforce screen on the go and performing searches or inputs on a small smartphone screen was a significant burden.

Therefore, LeanCard Sync deliberately adopts "LINE," which everyone is accustomed to using daily, as its user interface (UI). **The learning cost for operation is zero**. With the ease of sending a LINE message to a capable assistant, simply sending a business card image or a message like "Tell me the negotiation status of XX company" will prompt the AI to operate the complex Salesforce database behind the scenes and instantly return an answer.

By seamlessly combining "overwhelmingly easy-to-use LINE (UI)," "advanced generative AI (brain)," and "robust Salesforce (database)," we have realized a sales support system that sales representatives on the ground truly "want to use."

🚀 Three Key Features of This Major Update

1. Cross-Search Salesforce with Natural Language from LINE: "Deep Search"

While on the go or commuting, simply ask questions like "Tell me about the contact person from XX company I exchanged business cards with recently" or "Summarize the ongoing negotiations and past activity history of XX company" in the LINE chat screen. The AI will instantly cross-search data within Salesforce and provide a clear, summarized answer.

• Features: Batch search for accounts, opportunities, activity history, etc. It also supports follow-up questions based on previous conversations (e.g., "What's the negotiation status of that company?"), allowing for information gathering as if chatting with a capable assistant.

2. Investigate Latest Company Information with One Click: "AI Company Profiling"

By pressing the new "✨ Execute AI Profiling" button on the Salesforce account screen, the AI automatically searches, collects, and analyzes the latest information from the internet (company websites, news, etc.).

• Insights Gained: In addition to an accurate summary of business activities and automatic input of a detailed "industry" inferred by AI, it provides **"sales hypotheses (proposal angles and talk scripts) ready for immediate use tomorrow"** in just tens of seconds.

• Benefits: Dramatically reduces the time inside sales and sales representatives spend on preparation before approaching clients. Furthermore, by combining it with the existing "AI Analysis" function, it becomes possible to automatically analyze the acquired latest company information (external data) and past activity history, opportunities, and cases within Salesforce (internal data). Integrating internal and external information enables more specific and accurate approaches tailored to the customer's actual situation.

3. Smooth Organization on Smartphones: "Business Card List Screen"

A new list screen has been added, allowing for the complete organization and registration of business card information within the LINE app.

• Smart Sorting: You can intuitively operate by swiping or tapping to view images and choose options like "Create New in Salesforce" or "Overwrite Existing Data."

• Duplicate Check: The AI automatically checks for duplicate candidates, showing if the same person or company already exists in Salesforce, preventing duplicate data registration.

• Display Switching: You can switch between displaying "Only business cards I registered" and "All business cards in the company" with a single tap, allowing you to quickly find the desired business card.

⚡ Significant Performance Improvement

The process from sending a business card image via LINE to AI reading the text and registering the data in Salesforce has been significantly optimized. This has greatly reduced the waiting time until registration is complete, drastically decreasing the stress of business card processing. Additionally, the response speed of Deep Search (natural language search) has improved, allowing for smoother searches.

💡 Future Developments and Roadmap

1. Renewal of Free Version and Planned Provision of "Free Plan"

The previous "LeanCard Sync (completely free version)" has been discontinued due to changes in the specifications of external linked applications. Moving forward, a feature-limited "Free Plan" based on the new system is planned for provision. **This will allow more small and medium-sized enterprises to experience some of the latest AI assistant functions.**

Furthermore, data import from the business card management app "myBridge," which was widely used by many users in the old version, will continue to be available. The new system has moved away from relying on specific app linkage specifications and has been **refreshed with a general-purpose architecture where "AI automatically processes business card images simply by sending them to LINE."** This enables seamless registration of all business card images to Salesforce, whether shared from myBridge or photos taken on the spot with a smartphone camera, without being affected by external specification changes.

2. Development of "LINE WORKS" Integration Plan (Work Plan)

Currently, a "Work Plan" that integrates with the business chat tool "LINE WORKS" is under preparation. This will allow companies facing challenges with personal LINE usage for business (shadow IT) to utilize LeanCard Sync's AI assistant functions in a secure environment.
