StashBase is an innovative writing workspace designed to cater to writers who prefer a local-first approach. It is open-source and allows users to write, edit, and search documents without needing a constant internet connection. The platform integrates Claude and Codex, enabling users to draw on their own sources and past work to create content that truly reflects their voice.

The workspace functions similarly to an Integrated Development Environment (IDE) but is tailored for writing. Users can bring their files, editor, and agents together to explore ideas and write alongside their sources. StashBase offers features like text extraction and search, allowing users to find references in their documents, PDFs, and recordings.

StashBase is free to use under the Apache 2.0 license, with optional paid plans for those who wish to use the hosted Default Agent. The Plus plan is available for $10/month, and the Pro plan for $20/month, both offering additional agent credits. Users who already have subscriptions to Claude Code or Codex can use these without any extra charges.

The app is compatible with macOS, Windows, and Linux, making it accessible to a wide range of users. It is particularly beneficial for writers who want to maintain control over their documents and prefer not to rely on cloud storage. The platform's local-first approach ensures that files remain on the user's computer, with browsing, editing, and keyword search functioning independently of a cloud account.

StashBase was developed by Bing Wu and Li Liu, who have backgrounds in machine learning and vector database work, respectively. Their expertise has shaped the platform's capabilities, making it a robust tool for writers looking to integrate AI into their workflow without losing their personal touch.
