Turn folders into finished work.

OpenYak is a desktop AI agent, not a web chatbot skin. It reads local workspaces, runs tools, shows progress, and returns files, reports, tables, and other artifacts inside the app.

Local workspace

  1. Point Yak at a folder and keep the work near your files.

Tool execution

  1. File edits, shell tasks, parsing, browsing, memory, and artifacts in one loop.

Model choice

  1. Use cloud providers, local Ollama models, BYOK, or your subscription.

Private by default

  1. Designed for local-first teams that care about control and traceability.

Desktop workflows

Every use case maps to the real app. The site treats OpenYak like the desktop product it is: chat input, workspace scope, visible tool progress, settings panels, and concrete artifact outputs.

Use Cases

  1. Office Automation
    Rename, organize, and clean up files across folders with auditable logs. No more manual sorting.
  2. Data Analysis
    Parse XLSX, CSV, and document data locally. Spot anomalies, track trends, and export summaries — without uploading a single file.
  3. Team Operations
    Merge notes from PDFs, DOCX, and CSVs into structured briefs. Extract action items and assign owners automatically.
  4. Content & Writing
    Draft internal notices, policy updates, and professional communications from bullet points — all in consistent company tone.
  5. Remote Workflows
    Expose your local AI over a secure tunnel, scan a QR code, and pick up where you left off — from any device, anywhere.
  6. IM & Communication
    Connect WhatsApp, Telegram, Discord, Slack, WeChat, Feishu, DingTalk, WeCom, QQ, Email, Matrix, MoChat, or WebSocket channels. Your desktop AI agent can process messages through the built-in channel runtime.
  7. Knowledge & Memory
    Workspace Memory stores notes as a Markdown document scoped to each project directory. Context is automatically injected into every session, so your AI always knows the project.
  8. Integrations & Connectors
    46 pre-configured MCP connectors for project management, communication, data, design, CRM, and more. Enable with one click, authenticate with OAuth.

Visual System

The palette, density, window chrome, sidebar rhythm, model picker, composer, settings panes, and artifact rail follow the actual desktop application instead of a generic SaaS template.

Features

  1. Desktop shell
    Mac-style window chrome, a translucent dark sidebar, real chat rows, model selection, and the same compact toolbar structure.
  2. Local workspace
    Workspace scope stays visible through folder pills, project rows, and file-aware context instead of abstract marketing diagrams.
  3. Artifact rail
    Finished PDFs, tables, reports, and logs appear in the artifact rail next to the conversation, matching the app's output-first flow.
  4. Settings panels
    Provider, remote, automations, plugins, and memory screens are represented as dark settings panes based on the real app tabs.
