Bots That Deliver
Property Concierge Bot
A chat assistant built into a tenant-management platform. Landlords and butlers handle daily operations by chatting on WhatsApp, Telegram or Feishu.
Challenge
Landlords managing multiple units juggle repetitive questions (room details, contract terms, vacancy status) across scattered calls and messages. New-lease onboarding means tedious manual data entry from signed contracts, and properties without smart meters need someone to record every utility reading by hand each month.
Solution
Built a LangGraph tool-calling agent connected to the tenant-management system. Landlords ask about rooms, tenancies, vacancies or contracts in plain language (English or Chinese), and it answers from the live system. Send a photo of a signed contract and a vision-LLM pulls out the tenant, rent, deposit and dates to confirm before saving; send a meter photo and it reads the value and logs the usage.
Diagnostics Support Bot
An internal support chatbot for an EV-charging platform. Operators ask what's wrong with any charger or session in plain English, and it investigates the live system to find out.
Challenge
When a charge fails on an EV network of multi-vendor hardware, ops staff had to dig through OCPP status codes, database records and log stores across several systems to work out why. That slow work needed deep platform knowledge, so problems sat unresolved.
Solution
Built a conversational diagnostics agent into the admin console. Describe a symptom and anchor it to a charger or session, and it runs a guided investigation across 12 tools over the live database and OCPP logs, streaming its progress, then replies with a plain-English diagnosis and next steps. Seven root-cause playbooks steer it, personal data is redacted before the model sees it, and it's multi-LLM with side-by-side model comparison.
