We’re excited to announce the release of EmEditor v24.5.0. We strongly recommend all users update to this new version.

Many users depend on EmEditor for managing large files daily, so ensuring seamless opening, editing, and saving is essential. However, from versions v22.4.0 to v24.4.1, there was an issue where file sizes could increase when reopening large files (around 300MB or more) from certain hard drives, even though the first opening was fine. This was reported by a customer, and we appreciate his feedback and apologize for any inconvenience. This issue didn’t occur with fast hard drives like SSDs, but on slower drives with disk cache enabled, duplicate lines could appear. We fixed this in v24.4.2. In v24.5, we’ve added code to prevent such unknown issues by showing a message if there’s an internal file size inconsistency. Therefore, we strongly recommend all users update to v24.5.

Additionally, v24.5 introduces a new Verify command in the File menu. By selecting this command right after opening a file, you can save the current document as a temporary file and compare its size and SHA256 hash value with the original file.

The results are displayed in the File Verification Results dialog box, and you can copy the size and SHA256 hash value. Normally, the original and temporary files should match in size and hash value. However, discrepancies might occur if the original file contains NULL or invalid characters, or if there are hard drive or memory errors. For important files, please use the Verify command immediately after opening to ensure everything is correct.

We’ve also added an option in the File page of the Customize dialog box for automatic verification every time a file is loaded.

The new version (v24.5) also includes several other features, many of which were requested by users.

When dealing with large files, it can be convenient to open only a smaller section and navigate to the previous or next section by clicking a button. This was suggested by a customer. In v24.5, we’ve added << and >> buttons to the Large File Controller, allowing you to move to the previous or next section within a specified size range.

We’ve improved the AI-assisted writing feature by expanding the options available with the OpenAI API, which was initially introduced in version 24.1. Previously, suggested text would automatically appear in gray as you typed. Now, you have the option to display suggestions only when you press Ctrl+Space, which helps reduce the frequency of OpenAI API calls. If you prefer the automatic display of suggestions like before, they will only appear when the AI’s suggestion meets a certain confidence threshold, which you can now adjust. For instance, if you set the confidence to 40%, the AI will show suggestions only when it predicts the next text with at least 40% confidence. To minimize suggestions from less certain predictions, you can set a higher confidence, like 80%, ensuring that suggestions are shown only when predictions are more reliable, thus reducing the number of OpenAI API calls. Additionally, we’ve added options to adjust the length of the input text used for predictions and the output text for candidate suggestions. Using longer input text for predictions increases accuracy but also raises the OpenAI API usage fee. Similarly, longer output text results in more words being suggested.

Moreover, based on a request from a customer, we’ve made it so that pasting in the Chat with AI window won’t immediately send the message.

Bugs found during the preview version development have been fixed.

Finally, while EmEditor requires an internet connection for product activation, some environments need a proxy for internet access. In this version, we’ve added a Proxy Settings link in the Register Product dialog, enabling you to configure proxy settings easily. The desktop installer now includes a PROXY option for command line installation.

Today, we are releasing EmEditor v24.4.1.

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!
