For people whose work is thinking.
A desktop app that turns everything you’re working on into connected knowledge and lets AI agents work with you directly in your files. Everything is saved on your machine.
For the work you can't paste into ChatGPT.
Request early accessConnected knowledge
Chester connects information across your files and conversations, then surfaces the topics that matter most right now. Your files and knowledge stay in your local workspace.
Your documents, meetings, emails and AI chats become connected knowledge on your machine. Chester and other AI agents can draw on it, so the context you build stays useful across tasks, conversations and tools.
Your knowledge grows. Your AI starts ahead.
Chester recognizes the topics you’re working on and brings the related material together. See the proposal, the meeting that shaped it and the latest email side by side, without hunting through folders or remembering filenames.
Follow the subject. Not the folder.
Turn a client, project or research question into a living brief. As your knowledge grows, Chester brings changes, decisions and open questions into focus, with links to the sources behind them.
Stay current. See what changed.
Agent power
You and Chester work in the same files, backed by the connected knowledge of your workspace. Refine a paragraph or update a hundred documents.
Chester drafts and revises directly in your document, using your workspace’s knowledge. No copying into chat and back.
Build research databases, project trackers and comparison tables with Chester. Filter, group and summarize, with your data and saved views in one open file.
Bring ideas, sources and relationships onto one canvas. Map a strategy, connect the evidence and work through the big picture together with Chester.
Tools & automation
Chester writes and runs code, connects your tools and builds repeatable workflows. From complex analysis to finished reports, it turns your workspace’s knowledge into execution. No coding required.
Chester runs the workflow and saves the results and reusable code in your workspace.
Package your process, templates and standards into a skill you can use again.
Get briefings, reports and checks delivered to your workspace automatically.
Connect your apps so information and actions flow across one workflow.
Let compatible agents use your connected knowledge and workspace tools.
Ownership & choice
Your strategy, client context, decisions and methods are knowledge you’ve built over time. Chester keeps your files and accumulated memory in a local, portable workspace you control.
Choose a built-in model, connect your own provider or use a local or self-hosted model. Change the AI behind Chester without rebuilding your knowledge.
Chester is built around your workspace, not a conversation. It connects your documents, meetings, emails and AI chats into a growing memory of your work. You and Chester work directly in the same files, from writing and analysis to scripts and recurring workflows.
Your files, accumulated knowledge and reusable workflows stay together in a local, portable workspace you control. Change the AI behind Chester without starting over.
Yes. Your documents, data and scripts are saved in your workspace, not trapped inside Chester. You can open and edit all files in other tools, and run your scripts with the software they require.
Even Grids and Pulses use open, readable formats such as JSON, so other AI agents can read and interpret their contents without Chester.
Chester is for people who turn scattered information into decisions and useful work, from founders, managers and advisors to investors, analysts and researchers. If your work spans notes, documents, meetings and data, Chester is built for that kind of task.
Chester is optimized for business context and knowledge work, not developer workflows. It can write and run code for analysis and automation, but it is not designed as a dedicated software-development agent.
Grids are structured tables where you and Chester can compare options, organize records and analyze data together. Pulses are living briefs that show where a client, project or research question stands, with decisions, open questions and links to supporting sources.
Use a Grid to work through structured information. Use a Pulse to stay oriented as the underlying information changes.
Your workspace data and agent execution are local. Model processing depends on your configuration: a cloud model receives relevant content, while a local model processes it on your machine. Connected tools and any storage sync you use may involve other services. An offline workflow needs all of its required services to run locally.
