The problem
AI chat tools can answer questions, but people still copy, paste, reformat, and apply those answers back into real documents and spreadsheets.
About Lesser
An AI desktop workspace for document work that starts from your files.
Lesser is an AI desktop workspace that helps you work with Word, Excel, HWP, PowerPoint, and other office files in context. It is designed for the work that happens after an AI chat answer: reading files, comparing context, drafting edits, organizing tables, and saving useful work back into the files your team already uses.

Why not just ChatGPT?
ChatGPT, Claude, and Copilot are useful. Lesser is different because it is organized around your files, document context, and the workflow of turning an answer into reviewable work.
Start from files on your computer
Lesser is designed around the files and work context already on your computer. The MVP uses cloud AI models when needed; the point is not local model execution, but starting from the files and workflows you already use.
