TextFold · Fold Any Text, From a Map to Every Word

, ,

TextFold is a free, open-source tool and Python package that folds any text into five hierarchical levels, ranging from broad section maps down to individual words, enabling layered reading and analysis. It runs locally without uploading files, integrating with AI models for generating levels while preserving the original text, and supports various document formats on macOS, Windows, and Linux. Users can access it via a standalone app or embed it in AI workflows, making it useful for reading, summarizing without loss of source text, and agent-based document processing.

Privacy, Full Disk Access and AI Agents

, , ,

Apple is intensifying its review and enforcement of Full Disk Access (FDA) permissions in macOS to enhance user privacy, especially with the advent of AI agents like Meta’s Muse that require broad access to user data to operate autonomously. These AI agents demand sweeping FDA rights to interact with sensitive data such as Messages and Mail, raising concerns about potential inaccuracies, unexpected actions, and vulnerabilities like prompt injection, with users ultimately held responsible for agent behavior. Apple aims to refine FDA controls carefully to better protect privacy without adding complexity, though it remains uncertain whether this will effectively mitigate risks posed by autonomous AI on Macs.
