OpenYak helps you turn documents, spreadsheets, decks, PDFs, chats, and local project context into finished deliverables while keeping the workspace on your machine.

OpenYak is an open-source desktop agent for people who need AI to work with actual files, not isolated prompts. It combines chat, local tools, artifacts, model choice, and workflow continuity in one desktop workspace.
| What teams need | How OpenYak helps |
|---|---|
| Work from local context | Read and synthesize DOCX, XLSX, PPTX, PDFs, CSVs, folders, and project files. |
| Produce usable outputs | Generate briefs, tables, plans, diagrams, emails, and reusable artifacts in the same thread. |
| Keep data under control | Store conversations, files, memory, and artifacts locally by default. |
| Choose the model path | Use OpenRouter, bring provider keys, connect a ChatGPT subscription, or run local models with Ollama. |
| Continue beyond one prompt | Preserve long-thread context from analysis to planning, revisions, and follow-up work. |
Turn dense notes or office documents into a decision-ready brief with risks, owners, next steps, and a follow-up draft.
Use spreadsheets as working inputs. Ask for variance analysis, forecast risks, anomalies, owner-level action items, and meeting-ready talking points.
Synthesize several files in one thread and open a right-side artifact panel for reusable briefs, plans, diagrams, and structured outputs.
Real work rarely fits in one message. OpenYak is designed for follow-ups, revisions, long context, and clear recovery when something needs attention.

- Continue in the same thread as the work becomes more specific.
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.
