Yansu vs Dreamer
Dreamer builds autonomous AI agents that execute tasks. Yansu observes how you work 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, all from observed work patterns.
Last updated: March 2026. Yansu is made by Isoform. This comparison is based on publicly available information.

What is Dreamer?
Dreamer is an AI agent-building platform that lets users create autonomous agents via natural language prompts rather than building conventional web or mobile applications. The platform centers on "Sidekick," a personal agent that assists in creating and configuring other agents. Dreamer provides hosted infrastructure, removing the need for users to manage databases or API keys, and includes a community gallery where agents can be remixed and cloned. Agents run across desktop, iOS, Chrome extension, and email, and the platform supports self-modifying agents that can spawn sub-agents for complex workflows. Dreamer launched its open beta in February 2026. In March 2026, Meta acquired the founding team in an acqui-hire, with the technology licensed into Meta's Superintelligence Labs division. Dreamer's pricing was not publicly disclosed prior to the acquisition; the platform operated on a revenue-sharing model with tool creators rather than a conventional subscription.
What is Yansu?
Yansu is a proactive AI by Isoform that observes how you work, learns your patterns, and acts before you ask. Unlike tools that require prompting, Yansu runs in the background as a native desktop application on macOS, Windows, and Linux, continuously monitoring your desktop activity and messaging conversations across seven platforms including Slack, Microsoft Teams, Discord, Telegram, WhatsApp, Feishu, and WeChat. When Yansu identifies an opportunity to save time or reduce friction, it autonomously acts -- capturing knowledge, handing off a task, or setting up an automation -- tailored to your specific needs, with real data integrations from over 65 sources via OpenCLI. Yansu automatically selects the best AI model for each task from Claude, GPT, Gemini, and others. All data stays on your device with SOC 2 Type II and ISO 27001 certification. The free Basic tier includes limited daily chats and core features.
Key Differences
Proactive Action vs Agents
The most fundamental distinction between Yansu and Dreamer is what they produce. Dreamer creates autonomous agents -- background processes that receive instructions, execute tasks, and report results. An agent might monitor a news feed, draft a weekly summary, or trigger actions in other services. Yansu produces knowledge, handoffs, and automations -- it builds a living memory of how you work, takes discrete tasks end-to-end, and runs recurring jobs in the background using real data integrations. A Yansu automation might consolidate updates from Jira, Notion, and Slack into a daily digest, or monitor a competitor by refreshing from 65+ live data sources; a Yansu handoff might extract meeting action items and draft the tickets for you. Agents and Yansu serve different purposes: agents are best for repeatable background execution you configure, while Yansu acts on its own from observed patterns. Yansu does this proactively, without requiring you to describe what to do.
Code Ownership
Yansu's knowledge, memory, and automations live on your device in the ~/.yansu-agent directory. You can open, inspect, modify, and export any of it at any time. There is no vendor lock-in -- it is yours. Dreamer agents exist entirely within Dreamer's proprietary platform. There is no code export and no self-hosting option. All agent logic, configuration, and data lives on Dreamer's infrastructure. For teams with compliance requirements, data sensitivity concerns, or a preference for owning their tooling, Yansu's local-first approach provides substantially stronger guarantees. With the Dreamer team's March 2026 acquisition by Meta and the technology licensed into Meta's Superintelligence Labs, the long-term availability and independence of the Dreamer platform as a standalone product is an open question that teams should factor into any build-vs-buy decision.
Proactive vs Reactive
Dreamer requires you to initiate agent creation: you describe the agent's purpose, configure its behavior, and deploy it. The system is reactive -- it responds to your instructions. Yansu operates differently. It runs in the background, monitors your work across the desktop and seven messaging platforms, identifies recurring friction points and opportunities, and sets up automations and handoffs to address them without waiting to be asked. A team that repeatedly cross-references spreadsheet data in a Slack channel would find Yansu running an automation that surfaces those lookups before anyone thought to request one. This distinction matters most for non-technical users and busy teams: Yansu eliminates the step where you need to recognize a need, articulate it precisely, and spend time configuring a solution. The help arrives because Yansu observed that you needed it.
