 MindWork AI Studio is a free desktop app for macOS, Windows, and Linux. It provides a unified user interface for interaction with Large Language Models (LLM). AI Studio also offers so-called assistants, where prompting is not necessary. You can think of AI Studio like an email program: you bring your own API key for the LLM of your choice and can then use these AI systems with AI Studio. Whether you want to use Google Gemini, OpenAI GPT-6, or even your own local AI models.

 - **Tools**: AI models can use tools on their own, such as Web Search, Read Web Page, or Search Confluence. When you ask something a model cannot answer from what it knows, it looks it up and answers with the sources it used. You decide which tools a model may use, and you can watch it work.
+- **Your own data**: The AI can answer from your own documents. Add folders and files from your computer, or your organization's data through [ERI](https://github.com/MindWorkAI/ERI), as data sources, and the AI searches them whenever a question calls for it and names the passages it used. AI Studio keeps the index on your computer, and you choose the embedding provider, including one you host yourself. As a prototype, the AI can also search and read your mailboxes. Both are preview features, which you enable in the app settings first.
 - **Voice input**: Dictate your messages instead of typing them, and have your recordings as well as audio and video files transcribed. You choose the transcription provider, including one you host yourself.
 - **Unrestricted usage**: Unlike services like ChatGPT, which impose limits after intensive use, MindWork AI Studio offers unlimited usage through the providers API.
 - **Cost-effective**: You only pay for what you use, which can be cheaper than monthly subscription services like ChatGPT Plus, especially if used infrequently. But beware, here be dragons: For extremely intensive usage, the API costs can be significantly higher. Unfortunately, providers currently do not offer a way to display current costs in the app. Therefore, check your account with the respective provider to see how your costs are developing. When available, use prepaid and set a cost limit.
 - **Privacy**: You can control which providers receive your data using the provider confidence settings. For example, you can set different protection levels for writing emails compared to general chats, etc. Additionally, most providers guarantee that they won't use your data to train new AI systems.

 - **Flexibility**: Choose the provider and model best suited for your current task.
 - **No bloatware**: The app requires minimal storage for installation and operates with low memory usage. Additionally, it has a minimal impact on system resources, which is beneficial for battery life.

 Here's an exciting look at some of the features we're planning to add to AI Studio in future releases:
-- **Integrating your data**: You'll be able to integrate your data into AI Studio, like your PDF or Office files, or your Markdown notes.
+- **Agent mode:** You'll hand larger tasks to the AI. It plans the steps, asks for your approval, and works through them with the tools you allow, e.g., across your documents, mailboxes, and the web.
-- **Integration of enterprise data:** It will soon be possible to integrate data from the corporate network using a specified interface ([External Retrieval Interface](https://github.com/MindWorkAI/ERI), ERI for short). This will likely require development work by the organization in question.
+- **Your own tools:** Developers and IT departments will be able to define their own tools as plugins, so the AI can use, for example, an internal database or a specialist application of your organization.
+- **Notes and tasks:** You'll keep your notes and manage your tasks in AI Studio, together with the AI.
 - **Useful assistants:** We'll develop more assistants for everyday tasks.
 - **Writing mode:** We're integrating a writing mode to help you create extensive works, like comprehensive project proposals, tenders, or your next fantasy novel.
-- **Specific requirements:** Want an assistant that suits your specific needs? We aim to offer a plugin architecture so organizations and enthusiasts can implement such ideas.
+- **Voice control:** You can already dictate your messages. Next, we want the AI to answer with its voice (text-to-speech), and later on, to hold a natural conversation with you.
-- **Voice control:** You'll interact with the AI systems using your voice. To achieve this, we want to integrate voice input (speech-to-text) and output (text-to-speech). However, later on, it should also have a natural conversation flow, i.e., seamless conversation.
 - **Content creation:** There will be an interface for AI Studio to create content in other apps. You could, for example, create blog posts directly on the target platform or add entries to an internal knowledge management tool. This requires development work by the tool developers.
-- **Email monitoring:** You can connect your email inboxes with AI Studio. The AI will read your emails and notify you of important events. You'll also be able to access knowledge from your emails in your chats.
+- **Email monitoring:** You can already connect your mailboxes and let the AI search them in your chats, as a prototype. Next, the AI will watch your inboxes and notify you of important events, e.g., mails from certain senders or on certain topics.
 - **Browser usage:** We're working on offering AI Studio features in your browser via a plugin, allowing, e.g., for spell-checking or text rewriting directly in the browser.
 
 Stay tuned for more updates and enhancements to make MindWork AI Studio even more powerful and versatile 🤩.

@@ -35,10 +35,12 @@ Key structure:
 - **Sending content on** - Content which leaves one place for another, such as the result of an assistant sent to another assistant or a text sent into the chat, travels as a `TextLaunchPayload` through `AssistantLaunchService`, together with the restrictions of where it was written (`ChatRestrictions`, see `ChatThread.CaptureRestrictions`). Never hand over a bare string: the destination would let any provider or tool see content which its source kept from them. Build the payload with `AssistantLaunchService.CreateTextPayloadAsync`, which filters what an AI wrote for prompt injections before it reaches the next model as a message of the user. An assistant which allows sending to it overrides `AssistantBase.ApplyTextLaunchPayload`, and `SendToReceiverTests` checks that every one does; the restrictions themselves are applied centrally in `AssistantBase`.
 - **JSON in model answers** - Read the JSON part of a model answer with `ModelAnswerJson`, never with a scanner of your own. It skips the prose and code fences around the JSON but checks nothing, so broken JSON reaches the deserializer unchanged and its message can go back to the model.
 - **Long menus** - MudBlazor keeps a `MudSelect` inside the window by itself, but never a `MudMenu`: a menu taller than the window runs past its edge, and its lower entries cannot be reached. Give every `MudMenu` whose entries come from data, such as the assistants or the profiles, `MaxHeight="@MenuDefaults.MAX_HEIGHT"`, so that it scrolls.
-- **Growing popovers** - MudBlazor places an open popover only when it opens, when the window changes, and when its component renders again. Content which unfolds later, such as a `MudCollapse` or an `ExpansionPanel` inside a `MudPopover`, would therefore grow out of the window. `wwwroot/app.js` places every open popover again whenever its size changes, so such content needs no code of its own. This relies on `window.mudpopoverHelper.placePopoverByNode`, which is internal to MudBlazor: check that it still exists with every new MudBlazor version.
+- **Growing popovers** - Since version 9, MudBlazor places an open popover again whenever its content changes size. Content which unfolds later, such as a `MudCollapse` or an `ExpansionPanel` inside a `MudPopover`, therefore stays inside the window and needs no code of its own.
 - **Encryption** - Initialized before Rust service is marked ready
+- **Access to the app server** - Only the app window gets into the Blazor server. `AppAccessMiddleware` runs first in `Program.cs`, right after the host filter, and refuses every request without the session cookie of the window or with an origin other than the app's own. Add no exception for any path, not even for static files: `AppAccessPipelineTests` checks the order in `Program.cs`. Since nothing but the window holds the cookie, the app never sends a request to its own server: read files below `wwwroot/` through `WebRootFiles`. The system browser gets no cookie either, so never open a URL of the app server there; offer a save dialog through `RustService` instead, as the ERI Server assistant does for its specification. `runtime/AGENTS.md` describes the runtime side.
 - **Debug environment** - Reads `startup.env` file with IPC credentials
-- **Static files and the browser cache** - When the developer starts the app from Rider, the embedded browser of Tauri keeps the static files under `wwwroot/`, such as `app.css` or a script, in its cache. The app then still shows the old file, and a change seems not to work. Whenever you changed such a file, tell the developer to clear that cache through the developer tools of the embedded browser before testing. Users of a release are not affected.
+- **Boot link** - Once the .NET server is ready, a development build writes `dev-boot-link.txt` into the repository root. Opening that link hands another browser the session cookie. Open it only when the developer asks for it: the development build shows the data of the installed app.
+- **Static files and the browser cache** - When the developer starts the app from Rider, the embedded browser of Tauri keeps the static files under `wwwroot/`, such as `app.css` or a script, in its cache. The app then still shows the old file, and a change seems not to work. Whenever you changed such a file, tell the developer to clear that cache through the developer tools of the embedded browser before testing, and only the cache: the website data hold the session cookie, and without it the window shows "This window cannot access AI Studio. Please restart AI Studio." until the .NET server starts again. Users of a release are not affected.

-                      # Authentication and Authorization
-                      The process for authentication and authorization is two-step. Step 1: Users must authenticate
-                      with the API server using a `POST` call on `/auth` with the chosen method. If this step is
-                      successful, the API server returns a token. Step 2: This token is then required for all
-                      other API calls.
-                      
-                      Important notes:
-                      - Calls to `/auth` and `/auth/methods` are accessible without authentication. All other API
-                      endpoints require a valid step 2 token.
-                      
-                      - It is possible that a token (step 1 token) is desired as `authMethod`. These step 1 tokens
-                      must never be accepted as valid tokens for step 2.
-                      
-                      - The OpenAPI Description (OAD) for `/auth` is not complete. This is because, at the time of
-                      writing the OAD, it is not known what kind of authentication is desired. Therefore, you must
-                      supplement the corresponding fields or data in the implementation. Example: If username/password
-                      is desired, you must expect and read both. If both token and username/password are desired, you
-                      must dynamically read the `authMethod` and expect and evaluate different fields accordingly.
-                      
-                      The following authentications and authorizations should be implemented for the API server:

+                  successful, the API server returns a token. Step 2: This token is then required for all
+                  other API calls.
+
+                  Important notes:
+                  - Calls to `/auth` and `/auth/methods` are accessible without authentication. All other API
+                  endpoints require a valid step 2 token.
+
+                  - It is possible that a token (step 1 token) is desired as `authMethod`. These step 1 tokens
+                  must never be accepted as valid tokens for step 2.
+
+                  - The OpenAPI Description (OAD) for `/auth` is not complete. This is because, at the time of
+                  writing the OAD, it is not known what kind of authentication is desired. Therefore, you must
+                  supplement the corresponding fields or data in the implementation. Example: If username/password
+                  is desired, you must expect and read both. If both token and username/password are desired, you
+                  must dynamically read the `authMethod` and expect and evaluate different fields accordingly.
+
+                  The following authentications and authorizations should be implemented for the API server:
