Wisa is WinSell's AI office assistant, built for people who work in Vietnamese. Instead of switching between separate tools, you ask a question, attach a document and get the result in one workspace.

## What Wisa handles

Wisa focuses on four recurring jobs:

- Reading and summarising PDF, DOCX and TXT files up to 25MB.
- Drafting emails, reports, proposals and plans in Vietnamese.
- Running five-step Deep Research with an Evidence Ledger you can check.
- Turning ideas into software with KODA, a local agentic coding platform.

## How it differs from a plain chatbot

Wisa routes each request to 43 models from 9 providers: OpenAI, xAI, Anthropic, Zhipu AI, Google, DeepSeek, Moonshot AI, Longcat and MiniMax depending on the task. You can see which model answered, what it cost and which steps ran.

Reasoning Cards and Execution Traces make the work inspectable. When an answer matters, you check the evidence instead of trusting an unsourced paragraph.

## CUBE pricing

Wisa uses CUBE as its billing unit. The public rule is simple: 1 CUBE = 1 VND, with no markup on the underlying API price. The current plans are:

| Plan | Monthly price | CUBE |
| --- | --- | --- |
| Free | 0 VND | 10 |
| Starter | 99,000 VND | 100,000 |
| Standard | 199,000 VND | 220,000 |
| Unlimited | 499,000 VND | 600,000 |

You can start free and move to a paid plan when your workload grows.

## Who should use it

Wisa fits office, marketing, HR and teaching work, plus small teams that do not want to pay for several AI subscriptions. If your main job is writing code, KODA is the more direct choice.

## Getting started

Open wisa.vn, sign in with Google or email, and ask your first question. For long documents, upload the file and ask for a summary by section. For high-stakes work, use Deep Research and read the Evidence Ledger before sharing the result.

## Câu hỏi thường gặp
