A natural language command bar for your Mac's Finder window
Substage is a natural language command bar that docks neatly underneath your Finder windows. Tell it what you want to happen, and it takes action: "convert to a 1080p mp4", "word count", "zip these up", "author of this PDF?" and more! Free to try!
Substage handles document conversions (DOCX to Markdown, PDF extraction, page rotation, merging) and can automatically install required tools like Pandoc and Ghostscript. Users describe conversions in plain English rather than using separate applications.
Substage answers math questions (e.g., '5 foot 9 in cm?'), checks system specs ('What processor does this Mac have?'), and performs unit conversions using built-in tools. Results appear instantly without AI latency for deterministic calculations.
Substage Predicts simulates every command before running it, showing which files will be created, moved, deleted, or modified. Users set auto-run policies by side-effect category, ensuring they never execute unexpected destructive operations.
Substage translates plain English commands into terminal operations for tasks like converting video to MP4, resizing images, zipping files, and organizing folders. Users avoid learning shell syntax while maintaining full control through command preview before execution.
Substage subscription includes built-in access to multiple frontier AI models (OpenAI, Anthropic, Google, Mistral) with no configuration required. Alternatively, users can bring their own API keys or local models via Ollama for privacy-conscious workflows.
