Today, we are excited to announce the release of EmEditor v24.3.0.

In Version 24.0, we introduced AI macros to EmEditor. With this new version (v24.3), we’ve taken it a step further by integrating AI functionality using the OpenAI API directly into EmEditor. This allows you to interact with AI right from within the editor. The simplest way to do this is through the new Chat with AI bar. By default, this bar appears when you select Chat with AI from the View menu. You can enter your prompt here and press Enter to get a response from the AI. For multi-line prompts, use Shift+Enter to add a line break, or you can create your prompt in the editor, copy it, and paste it into the Chat with AI bar. You can also drag and drop your prompt. To copy the AI’s response, right-click and select Copy Message.

You can define frequently used prompts on the AI Prompts page in the Customize dialog. By default, prompts like “Send as is,” “Proofread,” and “Rewrite” are pre-defined. Prompts can include the entire document or selected text. For example, you can use the following placeholders:

$(DocText) Entire document
$(SelText) Selection
$(SelOrDoc) Selection or entire document

Using these, you can create prompts like:

Translate into French:
$(SelOrDoc)

In this example, if text is selected, it will be translated into French; otherwise, the entire document will be translated.

You can select the defined prompts from the AI submenu under the Tools menu, and they can also be accessed easily from the AI toolbar. If the AI toolbar is not visible, select AI from the Toolbars submenu in the View menu.

If you want to slightly modify a prompt before using it, right-click the prompt you want to use as a template from the menu or toolbar, and select New Prompt. This allows you to ask questions based on the selected prompt with modifications.

When defining prompts, you can also specify Output, Max tokens, and Temperature in addition to the message. For example, selecting Create New Document for Output will generate the AI’s response as a new document. If you are proofreading a document, selecting Split and Compare will display the document before and after proofreading side by side. Selecting Image will display the image specified in the prompt within EmEditor as a web browser. Adjusting the Max tokens can limit the number of words in the AI’s response. For example, if the Max tokens is set to 10, the response will be shortened to a few words. The Temperature setting controls randomness; a higher value results in more creative responses, while a lower value yields more consistent and accurate responses. Additionally, setting Save to Chat with AI will output the interaction with the AI to the Chat with AI bar, allowing you to monitor and save the conversation.

If you need common instructions for AI prompts, you can write them in the System role message for AI prompts section on the AI Options page in the Customize dialog. For example, writing “Do not use Markdown syntax” will prevent the AI from using Markdown syntax in its responses.

Additionally, based on customer feedback, you can now specify file names using regular expressions as well as wildcards in the File Types section of the Find in Files dialog. To use regular expressions, click the > button to the right of the File Types dropdown in the Find in Files dialog and select Regular Expression. For example,

Data[0-9]{1,3}\.txt

will target only file names from Data0.txt to Data999.txt for searching.

Since the previous version, an internet connection has been required for product registration, but some customers may not have access to the internet. Therefore, in this version, we have made it possible to register the product offline using the new /ol command line option. For customers who wish to do so, we will send an offline license file via email. Please refer to Offline Registration for more details.

We hope you enjoy using EmEditor, whether you choose the Professional or Free version. Please contact us or write in our forums if you have any questions, feature requests, or suggestions.

Thank you for using EmEditor!

Check out the EmEditor v24.3 New Features for more details and screenshots.

If you use the Desktop Installer version, you can select Check for Updates from the Help menu to download the latest version. If this method fails, please download the latest version, and run the downloaded installer. If you use the Desktop portable version, you can go to the Download page to get the latest version. Store App versions can be updated through the Microsoft Store (64-bit or 32-bit) after a few days.

Today, we are releasing EmEditor v24.2.0.

In the previous version (v24.1), we introduced the AI assisted writing feature using the OpenAI API. In this version, we have made further adjustments. The newly announced gpt-4o model from OpenAI has become the default preferred model, offering improved quality and speed for the writing assistance feature compared to the previous default gpt-4-turbo-preview model, while halving the usage fees incurred from OpenAI. The currently selected preferred model can be checked on the AI page of the Customize dialog. Additionally, we have adjusted to ensure unnecessary spaces do not appear in the suggested text for Japanese writing. Furthermore, the AI macro now acquires the OpenAI key and the preferred model set in the EmEditor core settings for ease of use, with slight adjustments made in prompt creation.

Responding to requests from corporate customers who have concerns about security, we introduced the ability to completely disable AI features. It’s worth noting that even if the AI feature is disabled in EmEditor, it’s impossible to completely prevent access to AI from web browsers or other tools if the computer is connected to the internet. However, it’s a legitimate administrator’s concern to prevent potential leaks of content opened in the text editor. Therefore, in the new version (v24.2), we’ve added a function to entirely disable AI with administrative privileges. By clicking the Disable AI (per computer) button on the AI page of the Customize dialog, it sets DisableAIAdmin = 1 (REG_DWORD) in the registry key HKEY_LOCAL_MACHINE/Software/Emurasoft/EmEditor v3/Common.

If this value exists, it prohibits not only the AI assisted writing feature but also any macros using the fetch function, including the AI macro. Since this value resides in HKEY_LOCAL_MACHINE, it cannot be deleted without administrative privileges. For the Store App version, which has restricted write access to HKEY_LOCAL_MACHINE, you need to manually create this value using the Registry Editor.

We plan to further develop AI-related features in future versions, so please stay tuned.

This version (v24.2) also responds to additional customer requests.

1. Since the initial versions of EmEditor, many customers (1, 2, 3) have requested a feature similar to the “Favorites” in web browsers that allows easy access to frequently used files. Therefore, in this version, we have added a Favorites toolbar and related commands. To add the currently open file to the Favorites toolbar, you can select the Add to Favorites command from the Favorites submenu of the File menu by default. This command saves not only the current file name but also the current cursor position. You can also drag the document tab or file icon from Explorer and drop it onto the Favorites toolbar. However, in the case of drag and drop, the cursor position is not saved. You can rearrange the buttons by dragging and dropping the added buttons. To remove a button from the Favorites toolbar, right-click on the button and select Remove from This List from the menu displayed. This feature is supported in both EmEditor Professional and EmEditor Free.

Furthermore, in EmEditor Professional, you can customize the appearance, icon presence, and display method of the Favorites toolbar on the Favorites page of the Customize dialog box. Additionally, you can display a list of files registered in favorites and edit the cursor position for each file.

To elaborate on the drag-and-drop functionality of the toolbars: similar to the Favorites toolbar, it is now possible to rearrange the order of buttons on the Macros, Markers, and Tools toolbars through drag-and-drop.

2. In response to requests from some customers (1, 2), we have added the GetKeyState method to the Shell object, which retrieves in macros whether a certain key is pressed down.

Additionally, starting with this version, we have ended support for per-computer installations due to security concerns. This change removes the need for administrator privileges during installation and updates, increasing security. From this version, the installer supports only per-user installations, has a new design, and simplifies the installation process. Some settings previously available in the installer can be changed after installation via the Shortcuts page of the EmEditor Customize dialog.

However, some organizations prohibit installing apps in user folders, and require installations in specific folders (for example, C:\Program Files\). If you need to change the installation folder, please see FAQ: How do I change the install folder?

Using the portable version can also help avoid problems. By default, the portable version creates INI files in the same folder as emeditor.exe to save settings. In the new version, settings can be saved to other folders by editing the eeUseIni.ini file located in the same folder as emeditor.exe. For example, if you change the eeUseIni.ini file as follows and save it in UTF-16LE (with BOM), the settings will be saved in the folder C:\Users\(username)\EmEditorSettings.

[IniDir]
IniDir=%UserProfile%\EmEditorSettings

This method allows all users to share the app while having their own settings, similar to installing EmEditor as per computer.

As noted in a previous blog, unfortunately, some users have accidentally purchased or acquired invalid licenses. While those distributing or selling invalid licenses are most at fault, we also acknowledge that EmEditor’s specifications allow usage for a certain period even with invalid registration keys. Starting from this version, an immediate issue notification is displayed if an invalid license is entered. Additionally, entering the email address associated with the Emurasoft Customer Center will be mandatory when entering a registration key. If you purchased a license directly from our website, use the email address provided during purchase. If purchased elsewhere, register your product with the Emurasoft Customer Center and use the email address used during registration. If you forget your registered email address, please contact us.

I hope you like EmEditor, whether you use the Professional or Free version. Please contact us or write in forums if you have any questions, feature requests, or any ideas in the future.

Thank you for using EmEditor!

Today, we are releasing EmEditor v24.1.1.

v24.1.1 includes the following bug fixes.

• Adjusted the AI assisted writing feature to prevent suggestions after a period or newline.
• Adjusted the AI assisted writing feature to allow Ctrl+Space to show a suggestion before the end of line.
• Adjusted the Explorer context menu feature to allow toggling of both the modern and classic context menus separately.

If you use the Desktop Installer version, you can select Check for Updates on the Help to download the newest version. If this method fails, please download the newest version, and run the downloaded installer. If you use the Desktop portable version, you can go to the Download page to download the newest version. The Store App versions can be updated through Microsoft Store (64-bit or 32-bit) after a few days.

Today, we are releasing EmEditor v24.1.0.

In version 24.1, we have added support for the new context menu in Windows 11 Explorer. With Windows 11, the design of the context menu has been revamped compared to Windows 10 and earlier versions, necessitating special handling for apps to support this change. EmEditor is now compatible with the Windows 11 context menu, enabling you to directly select the Edit in EmEditor command. Additionally, when right-clicking on a folder or the background, the Find in Files with EmEditor command becomes available. To use this feature, the EmEditor tray icon must be displayed in the notification area of the taskbar, and it is supported only when running the desktop installer version on Windows 11. This feature is accessible in both the EmEditor Professional and EmEditor Free versions.

Another significant feature added in the new Professional version is the enhancement of AI capabilities. Version 24.0 introduced AI macros using the OpenAI API (hereafter abbreviated as “API”). Version 24.1 introduces an AI assisted writing feature that predicts and autocompletes what you are typing next while composing text. AI autocomplete can reduce typing effort and improve writing speed. I am writing this text using EmEditor and am personally experiencing the convenience of the AI assisted writing feature.

By default, the AI functionality is disabled. To enable this feature, you need to check the Enable AI option on the AI page of the Customize dialog box in EmEditor, and agree to allow OpenAI to process the text data within documents opened in EmEditor. Please read OpenAI’s Privacy Policy, and if you agree, click the Continue button. According to this privacy policy, data sent to the API will not be used for training OpenAI’s models.

Next, enter your API key in the OpenAI API Key text box. If you are logged into OpenAI, you can obtain your API key here. It is recommended to store the API key in the ‘OPENAI_API_KEY‘ environment variable, but if you use the portable version of EmEditor or do not wish to share the key with other apps because you are sharing the computer, you can disable the Use “OPENAI_API_KEY” environment variable option and save the API key exclusively for EmEditor. By default, gpt-4-turbo-preview is the preferred model. It offers more accurate suggestions than gpt-3.5-turbo. For writing in foreign languages, selecting gpt-4-turbo-preview is advisable. Also, to enable this feature, you must activate the AI assisted writing option on the General page of each configuration properties. It is enabled by default for Text, Markdown, and HTML configurations.

When this feature is enabled, as you type, AI will automatically predict and suggest the next text. The suggested text appears in gray by default, and you can accept the suggestion by pressing the Tab or End key. If you want to accept only part of the suggested text, press the Right arrow key for the number of characters to accept, or Ctrl+Right to accept one word. Pressing the Delete key will remove the first character of the suggested text. Pressing the Esc key or another key cancels the suggestion. Moreover, if you want to force a prediction by AI when no suggested text is displayed, or request a different suggestion, press Ctrl+Space.

Simply opening a file in EmEditor does not call the API. It only starts calling the API when you begin typing characters. Moreover, the following conditions must all be met to utilize this functionality:

• Running EmEditor Professional edition
• The Enable AI option is set
• The AI assisted writing option is set
• Not recording or running a macro
• The Read-only option is turned off
• No text is selected
• Not editing a very large file
• Not in CSV mode
• Not comparing files
• The document being edited is active
• The cursor is at the end of line
• Have started typing characters
• After pausing typing (about 100ms)
• Have not pressed the Esc key to cancel a suggestion
• Not just clicked elsewhere with the mouse or executed another command

As described above, we aim to minimize the frequency of API usage. However, using the API still incurs a fee payable to OpenAI, calculated in tokens. Each suggestion consumes about 100 tokens for input and about 10 tokens for output. According to current pricing, using the default gpt-4-turbo-preview model consumes approx. US$0.0013 per instance. Opting for gpt-3.5-turbo significantly reduces the cost to approx. US$0.000065 per instance. For reference, using ChatGPT Plus provided by the same company incurs a monthly fee of US$20 or more, but if you only use the API with EmEditor, you don’t need to pay for ChatGPT Plus. Using AI with EmEditor is unlikely to amount to US$20 a month, making it an economically viable option. Using the AI macro introduced in v24.0, you can ask EmEditor any free-form questions just like with ChatGPT Plus, making it possible to completely replace ChatGPT Plus with EmEditor.

Furthermore, this version responds to customer requests.

1. The hexadecimal characters used for IPv6 addresses in highlight and sorting commands were only recognized in lowercase in previous versions. This was because RFC 5952 recommends writing IPv6 addresses in lowercase. However, based on feedback from a customer indicating that both uppercase and lowercase letters may be mixed, we now support uppercase letters as well.

2. The CommitList plugin has been improved with the addition of the Delete Remote Branch command.

I hope you like EmEditor, whether you use the Professional or Free version. Please contact us or write in forums if you have any questions, feature requests, or any ideas in the future.
