What is Yansu? +
Yansu is a proactive AI app builder by Isoform that observes how you work, learns your patterns, and automatically builds custom applications before you ask. Unlike traditional no-code tools or AI assistants that require prompting, Yansu acts autonomously. Learn more about Isoform.
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 app generation uses whichever model performs best for that specific operation.
What platforms does Yansu support? +
Yansu is available for macOS (Apple Silicon & 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 crystal libraries, and admin controls. Yansu can observe team-wide patterns and build apps that benefit everyone.
How is Yansu different from ChatGPT or Copilot? +
Unlike ChatGPT or Copilot, Yansu is proactive -- it observes your work patterns and builds custom applications without being prompted. It does not require you to describe what you need; it figures that out by watching how you work.
What kind of apps can Yansu build? +
Yansu builds custom internal tools, dashboards, trackers, and workflows tailored to your team's specific patterns. Examples include project trackers that consolidate data from Jira, Notion, and Sheets, AI spend monitors, and automated meeting action item extractors.
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. Isoform is SOC 2 Type II and ISO 27001 certified.
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 builds apps automatically. You just keep working as usual -- Yansu handles everything from design to deployment.
