Oxygen AI Positron for Desktop

• OpenAI GPT-5.2 Models Available - The flagship GPT-5.2 and GPT-5.2 Thinking models, OpenAI's flagship models for agentic tasks, are now available in the list of OpenAI models to choose from. The Thinking variant is designed for complex tasks and multi-step decisions where accuracy matters more than speed.
• Sensitive Data Masking for AI Requests - Personal or private information (such as email addresses, phone numbers, IDs, or API keys) is now automatically identified and masked in AI requests to help protect sensitive data. You can extend this protection by adding custom patterns to cover additional data types. The masked information is automatically restored in the AI response, ensuring that users see the correct content and that any generated or updated files remain accurate.
• Improved Review Experience for AI-Modified Files - All files created or modified by AI now appear directly in the chat area, so you can review the proposed changes and accept or discard them without leaving the conversation. You can also open each file individually and accept only a subset of the proposed changes while rejecting the rest.
• Optimized Token Consumption for AI Prompts and Tools - The prompts and tools that the AI uses to generate answers have been improved to consume fewer tokens/credits.
• New Planner Chat Mode for Resource Consuming Tasks - The newly-introduced Planner chat mode is available for complex, token-intensive operations (e.g. "Translate all files in the current folder" or "Find all conrefs and replace them with conkeyrefs in userguide.ditamap"). After being given the prompt, the AI explores your project, proposes a multi-step plan, and after your approval, delegates each step to the most suitable AI agent. This means large, project-wide changes can be coordinated without hitting LLM context limits, while still showing you the tool calls and results for review.
• Smarter PDF/Word Attachment Expansion in Planner Mode - When using the Planner chat mode with PDF or Word (.docx) attachments, the document is automatically split into multiple Markdown files, with embedded images extracted into a temporary folder. This allows the Planner to invoke sub-agents that can process, transform, or convert the extracted files and assets as needed (for example, converting them to other formats or generating new project structures).
• More Context Information Available in Chat - The AI chat now automatically includes additional information about your environment and editing context, such as the Oxygen application version, operating system details, current date, main file information, and caret or selection data (Oxygen 28.1 or newer).
• Tools Selector - You can now customize the AI's capabilities for each chat mode. The new Tools selector allows you to disable or enable specific tools (either added via Model Context Protocol or provided in the chat mode definition), giving you more control to fine-tune the AI's responses and behavior for your specific tasks.
• Chat Selection Includes Images - When you use the AI chat with content selected in your document, any images within that selection are now also included for the LLM to analyze along with the text.
• Create New AI Chat Modes - You can now extend the AI chat by creating your own custom chat modes. This allows you to build specialized assistants tailored to your specific needs and workflows.
• AI Positron Fix Action Turns Agentic - The AI Positron Fix action now automatically applies proposed fixes directly in your document and continues to explore additional sections when more context is needed.
• Documentation and APIs to Create New Chat Modes - You can now officially define new chat modes by creating new AI actions that contain the "output-action": "agentic" property.
• Tools to List and Invoke AI Agents - Newly added tools make it possible to create powerful new chat modes to plan complex changes and then use separate agents for each part of the plan.
• Tool to Run Command Line - A newly added tool is available in all chat modes and can be used to invoke a command line process. Note that the tool needs explicit user approval when it is invoked.
• Tool to Copy/Move/Rename Local Resources - A new tool is available in all chat modes and can be used to copy, move, or rename a local file or folder path. When used in Oxygen 28.1 and newer, if the Main Files feature is enabled in Oxygen, references to the moved or renamed resource are also automatically updated.
• Control AI Action Visibility - You can now choose whether a defined AI action is visible in the UI or only available to other AI actions as a sub-agent by using the new visibility property.
• Create AI Actions with Vision Support - You can now decide whether a custom AI action sends both content and referenced images to the LLM by using the "input-type": "markup-with-images" JSON property. This helps you include images only when they are relevant for the AI response.
• Generate Image Alternate Text Improvements - The Generate Image Alternate Text action can now be used on all images that are referenced within a document at once, while you can still use the action on individual selections as well.
• Preserve Structure and Styles for Attached Word and PDF Documents - When attaching Word (.docx) or PDF documents in the chat, their internal structure (headings, lists, tables, code blocks) and styling (bold, italic) are now preserved when being sent to the AI so that it better understands the document.
• Updated Model Context Protocol Library - The Model Context Protocol SDK that is bundled with AI Positron 8.1 has been updated to contain the latest fixes in the 0.16.0 SDK.
• Removed Support for Older Models - Support for older models (such as GPT-4, GPT-4 Turbo, GPT-4o, Sonnet 3.7, and more) has been removed. Alternatives with improved characteristics are available, such as models with higher intelligence, lower prices, or larger context windows.
