Yttri 0.86.0-beta.1: First Obsidian Plugin, MLX Engine and Unified Agent Interface

Yttri released version 0.86.0-beta.1 — a major beta update with four directions of changes: the agent received a unified section in the interface, a plugin platform was launched with the first integration for Obsidian, an alternative local MLX engine launched on Mac with Apple Silicon, and voice input and recording went through a tight series of stability patches.

What changed for agent users

Before 0.86.0-beta.1, Yttri's agent functions were scattered across different sections of the application. In the new version, the agent received a dedicated "home" — a unified section with a centralized entry point, from which you can launch tasks, view session history, and manage active processes.

This change solves several problems simultaneously. First, the user no longer spends time searching for the right control element. Second, a unified interface makes agent mode more visible and lowers the barrier for those who haven't used it regularly yet. Consolidation of agent functionality is a typical step of a mature product that transitions from a set of capabilities to a thoughtful user experience.

Why plugins appeared and what Obsidian has to do with it

The main system news of the release is the launch of an official plugin platform. Until this point, Yttri was a closed product without extension points for external developers. Now they have an official architecture for creating integrations.

The first plugin became Obsidian integration — a popular tool for maintaining a personal knowledge base based on local Markdown files. Key details of the update:

• Release — 0.86.0-beta.1 (beta version)
• Plugin platform — open, first plugin already available
• Obsidian integration — direct access to local vault without cloud
• MLX — alternative local engine for Mac with Apple Silicon
• Voice input and recording — several waves of stability patches

Integration with Obsidian allows the Yttri agent to work directly with the user's local notes without uploading them to the cloud. For those who store work archives, research databases, or personal knowledge systems in Obsidian, this opens new scenarios: the agent can build answers taking into account accumulated context, rather than being limited to external sources.

The choice of Obsidian as the first plugin is not accidental. The Obsidian audience largely overlaps with those who seriously work with AI tools: developers, researchers, content creators. Launching a platform with this integration suggests deliberate positioning.

MLX Engine: native AI for Mac on Apple Silicon

Mac users with M1, M2, M3, and M4 chips got MLX support — an open source machine learning framework that Apple released in December 2023. MLX is designed specifically for Apple Silicon's unified memory architecture: it leverages CPU, GPU, and neural engine through a single pool of RAM, which reduces latency when transferring data between components.

In practice, this means faster local inference compared to CPU-only approaches. Data remains on the device — without uploading to the cloud. MLX is added to Yttri as an alternative to other local engines: the user chooses what works best in their specific configuration.

Voice input became more stable

Voice features — speech input and recording — went through a "tight series of stability fixes." In previous versions, voice mode was among the most unreliable components of Yttri. In the current beta cycle, developers clearly made it a priority: specific fixes in the release description are not decrypted, but systematic work on voice is a signal that the feature is moving toward production quality, rather than remaining experimental.

What this means

Yttri 0.86.0-beta.1 is a transition from a set of features to a product platform. Plugins open the ecosystem to third-party developers, MLX closes an important segment of the Mac audience, and consolidation of the agent interface prepares the product for a wider circle of users. What plugins appear next will show the direction the team sees for the future of the tool.
