PASTEMAX

Local-first AI context builder by Auto Scale Agency.
Build clean, trustworthy prompt payloads from your local codebase without sending files to a cloud service.

Built By Auto Scale Agency

PASTEMAX is made by Auto Scale Agency for developers who work with AI coding tools and need a fast, local, repeatable way to copy the right project context.

It stays focused on the desktop workflow: select a folder, choose the files that matter, add instructions, check the token budget, and copy a structured payload for ChatGPT, Codex, Claude, Gemini, or any LLM workflow.

PASTEMAX 2.1

Version 2.1.0 focuses on polish and trust:

• Local secret warnings before clipboard writes for .env files, private keys, API keys, tokens, JWTs, and similar sensitive values.
• Better copy states for copying, copied, failed, empty selections, and warning-blocked copies.
• Stronger History with search, workspace/project filters, Copy XML, and Restore selection.
• Workspace switching that cleans up stale selections and keeps recent folders easy to reopen.
• Cleaner GitHub Releases update checks with retry, timeout handling, and an Open Releases fallback.
• Better empty and error states across Explorer, History, Workspaces, file scanning, updater, and warning flows.

Core Features

• File tree navigation with search, sorting, and binary-file detection.
• Token estimates for selected files and target model context windows.
• XML-style prompt payloads that keep file paths, file contents, and user instructions organized.
• Workspace management for frequently used projects and folders.
• Copy History for reopening previous payloads or restoring a past selection.
• Local-only secret scanning before copy. Findings are shown with redacted values.
• Automatic update checks through this repository's GitHub Releases.
• Light and dark desktop UI for macOS, Windows, Linux, and WSL workflows.
