Note 1
Start writing...
Built for private work first.
Use Boolean locally with GGUF models. Sign in only when you want optional cloud tokens or online providers.
Browser beside chat
Open pages, read visible content, send screenshots to notes, and keep research inside the same workspace.
Notepad included
Keep snippets, screenshots, drafts, and selected chat text in a clean paper-style notepad.
Local models
Run supported GGUF models on your PC with no required account for standard local use.
Optional cloud
Google Sign-In, Boolean Cloud tokens, or your own provider API key are available when you want online models.
User controlled
Local mode keeps prompts and files on the computer. Risky actions can require approval.
Offline models
Pick a model, download once, use it locally.
Boolean can help users choose a home-friendly model, download it into the right folder, and switch when the task changes.

Compare
Boolean is built for local-first desktop work.
