17a-4 LLC has added an API to its DataParser Hub that lets clients send proprietary content into Microsoft Purview and Copilot. The New York company announced the feature on October 21, 2026. DataParser already captures more than 30 types of messaging and collaboration data, including Slack, Webex, Symphony, and Zoom. Some clients also hold custom content, such as JSON exports from agentic AI, that no standard connector covers. The new API offers a formatted schema for ingestion, so clients need not build their own M365 integrations. Data sent to Hub can appear in Outlook, be available to Purview's Communications Compliance and eDiscovery, and feed into Copilot. Clients can also store it in Azure Blob. Output can tie into a client's Active Directory, and metadata can flag data type or classification.

Software engineer Dominik Picheta has built KillSwitch, an open-source programming language designed to confuse large language models (LLMs). Picheta is a senior software engineer at Cloudflare and a core developer of the Nim language. The language uses adverbs as identifiers, and calling one requires an anagram of it. Most text in a program is ignored by the interpreter, while phrases such as "ignore previous instructions" call functions. The spec document also contains deliberate lies to mislead models that scrape it. Picheta tested several major models. The best scored 66.8% on KillSwitch coding tasks, while most struggled to pass 50%. He does not believe even that score shows the models understand the code. KillSwitch is available on GitHub.

A new open-source tool called RemoveMacAI allows users to completely remove Apple Intelligence from macOS and reclaim up to 12GB of storage space. Created by Om Lahorey, the tool emerged after Apple made it nearly impossible to fully disable AI features in macOS 27, with settings scattered across multiple locations. RemoveMacAI eliminates Siri AI, ChatGPT extensions, Genmoji, writing suggestions, notification summaries, and automatic photo clean-up. It works by installing a configuration profile using Apple's own restriction keys and removing models through Apple's asset service. The tool has gained over 1,500 stars on GitHub. Users can install it via Homebrew or a curl command, disable features selectively or completely, and revert changes if needed. Apple System Integrity Protection remains enabled, and dictation continues functioning. However, future macOS updates might break the tool's functionality.
