OpenYak

A local-first AI agent for files, tools, long threads, and real desktop work.

Run an agent on your own computer, work with local files, use local models when you can, and choose cloud providers only when you want them.

Why OpenYak

OpenYak is built for people who want an AI agent that lives on their machine instead of behind another hosted workspace account.

• No OpenYak account. Install the app, choose a local model or bring your own provider key, and start working without login, billing, seats, or recharge flows.
• Local-first agent runtime. Files, conversations, memory, generated artifacts, tool permissions, and workflow state stay on your device.
• Work from your actual files. Attach DOCX, XLSX, PPTX, PDFs, CSVs, and local project context, then ask for briefs, tables, follow-ups, plans, and reusable artifacts.
• Keep the workflow in one thread. Start with analysis, continue into a RACI, ask for a follow-up email, and preserve context across long conversations.
• Choose your model boundary. Run local models through Rapid-MLX or Ollama, or opt into direct BYOK calls to OpenRouter, OpenAI, Anthropic, Google, and other providers.
• Use your desktop agent from another device. Remote access lets you scan a QR code and send tasks to your computer through a secure tunnel.

What It Feels Like

Office Workflows

From Memo to Executive Brief

OpenYak can turn a dense memo into a structured brief that is ready for a manager, team update, or follow-up email.

From Spreadsheet to Finance View

Use spreadsheets as working inputs, not screenshots. Ask for budget variance, forecast risks, owner-level action items, and meeting-ready talking points.

From Multiple Files to an Artifact

OpenYak can synthesize several files in the same thread and open a right-side artifact panel for reusable briefs, plans, diagrams, and structured outputs.

Multi-Agent Task Batches

Split a larger request into focused child-agent tasks, run them in parallel, and keep the parent thread as the place where progress, links, and the final aggregate result come back together.

Long Threads and Auto-Compress

Real office work rarely fits in one message. OpenYak is designed for follow-ups, revisions, and long conversations where the important context needs to remain available.

Get Started

1. Install OpenYak for your platform.
2. Choose where inference runs: local Rapid-MLX/Ollama for offline work, or a BYOK cloud provider when you want hosted models.
3. Start a new conversation and attach a real file.
4. Ask for a deliverable, not just a summary: brief, action plan, RACI, email, table, or artifact.
5. Review the result in the chat and artifact panel, then continue in the same thread.

Example prompt:

Please read the files I uploaded and turn them into a concise team brief.
Start with three key takeaways, then list risks, owners, and next actions.
Finally, write a follow-up email I can send to the team directly.

Model Options

Local First

• Rapid-MLX: Apple Silicon macOS users can start and switch curated MLX models from Settings. OpenYak connects to Rapid-MLX's OpenAI-compatible API on localhost.
• Ollama: Run any model available through Ollama. Local models are auto-detected and can be used without an internet connection.
• Custom local endpoints: Point OpenYak at a local OpenAI-compatible server when you run your own model stack.

Optional Cloud Providers

Cloud and subscription paths are optional. OpenYak does not provide hosted model accounts and does not proxy model traffic; requests go directly from your desktop to the provider you configure.

Core Capabilities

• File understanding: office docs, spreadsheets, slide decks, PDFs, CSVs, local folders, and generated artifacts.
• Artifact workspace: reusable Markdown briefs, tables, diagrams, checklists, and structured outputs.
• Tool execution: read, write, rename, organize, and automate files with user-controlled permissions.
• Long-context work: continue from analysis to planning to follow-up without starting over.
• Remote access: connect from mobile through QR code and Cloudflare Tunnel.
• Automations: schedule recurring cleanup, reporting, and file workflows.
• Privacy controls: local storage, no OpenYak account, BYOK provider access, and local model support.
