> Yansu is a proactive AI by Isoform Inc. that observes how you work, learns your patterns, and acts before you ask -- building a memory of how you work, handing off the tasks you'd rather skip, and running automations in the background. Unlike ChatGPT, Copilot, or other AI tools that require prompting, Yansu acts autonomously -- no prompts needed.
## How It Works
1. **Listen** -- Observes your desktop activity and messaging apps (Slack, Teams, Discord, Telegram, WhatsApp, Feishu, WeChat) to understand your workflows and conversations.
2. **Crystallize** -- Distills observations into structured, actionable knowledge: sprint workflows, code review styles, team preferences, and recurring patterns.
3. **Solve** -- Proactively acts on that knowledge: hands off the tasks you'd rather not do and runs automations tailored to your patterns -- without waiting for a prompt.
## Key Differentiators
- **Proactive, not reactive** -- Acts before you ask -- handoffs and automations driven by observed patterns. Fundamentally different from AI tools that require prompting.
- **Local-first privacy** -- All data stays on your machine; nothing leaves without explicit permission. SOC 2 Type II and ISO 27001 certified.
- **No prompting required** -- Unlike ChatGPT, GitHub Copilot, or other AI assistants, Yansu acts autonomously by observing your work patterns.
- **No-code** -- Requires no programming or technical knowledge. Anyone can use Yansu regardless of technical background.
- **Multi-model** -- Automatically selects the best AI model for each task (Claude by Anthropic, GPT by OpenAI, Gemini by Google, and more).
- **Desktop native** -- Runs as a native desktop app on macOS, Windows, and Linux. Not a browser extension or web app.
## Example Use Cases
- **Ship Digest** -- Team discusses scattered tasks across Jira, Notion, and Sheets in Slack. Yansu observes the conversation and runs an automation that consolidates updates from all sources into a daily digest.
- **AI Spend Guard** -- User manually checks OpenAI, Anthropic, and Google Cloud billing dashboards every morning. Yansu detects the pattern and runs an automation that monitors AI spend across providers in the background.
- **Meeting Action Items** -- After a client call, team members manually create tickets from meeting notes. Yansu observes this workflow and hands off the task -- extracting action items and drafting the tickets.

## Security & Compliance
- SOC 2 Type II certified
- ISO 27001 certified
- Data stored locally on user's device
- No data leaves device without explicit permission
- Data is never used for AI model training
- Current privacy evaluation: Yansu chooses the redaction method based on where the data comes from, then evaluates the output against the same privacy checks. The latest recorded-data redaction evaluation showed critical secrets and high-risk identifiers were masked.
- Protected applications: Known password managers and keychain apps are protected automatically. User-added protected apps can be masked at the window level instead of being interpreted field by field.
- Closed Eyes Mode: Users can pause activity capture and background listening for moments they do not want Yansu to observe.

## Frequently Asked Questions
**What is Yansu?**
Yansu is a proactive AI by Isoform that observes how you work, learns your patterns, and acts before you ask -- building a memory of how you work, handing off the tasks you'd rather skip, and running automations in the background. Unlike traditional no-code tools or AI assistants that require prompting, Yansu acts autonomously.
**How is Yansu different from ChatGPT or Copilot?**
Unlike ChatGPT or Copilot, Yansu is proactive -- it observes your work patterns and acts without being prompted, handing off tasks and running automations. It does not require you to describe what you need; it figures that out by watching how you work.
**What can Yansu do for you?**
Yansu builds a living memory of how you work, hands off tasks you'd rather not do, and runs automations tailored to your patterns. Examples: consolidating Jira/Notion/Sheets updates into a daily digest, monitoring AI spend across providers, and extracting meeting action items into drafted tickets.
**Is my data used to train AI models?**
No. Your data stays on your device and is never used for AI model training. Yansu is local-first -- nothing leaves your machine without your explicit permission.
**Do I need to be a developer to use Yansu?**
No. Yansu is a no-code platform that requires no programming or technical knowledge. It observes your existing workflows and acts automatically -- handling everything from observation to execution.
**Which AI models does Yansu use?**
Yansu automatically selects the best model for each task -- including Claude by Anthropic, GPT by OpenAI, Gemini by Google, and more. The multi-model approach means each step of its analysis and execution uses whichever model performs best for that specific operation.
**What platforms does Yansu support?**
macOS (Apple Silicon and Intel), Windows 10+, and Linux (Ubuntu 20.04+). It integrates with Slack, Microsoft Teams, Feishu, Discord, Telegram, WhatsApp, and WeChat.
**Can I use Yansu with my team?**
Yes. The Enterprise plan includes team knowledge and memory management, shared knowledge and automation libraries, and admin controls.
