Announcements

Updates and notices from MolSketch.

Feature Added

Periodic Table Tool Released

We have released a periodic table tool that allows you to quickly check basic information about elements. With simple operations, you can view information about each element.

Feature Addition

MolSketch Hub Released

MolSketch has been renewed as a tool hub where multiple scientific and educational tools can be used collectively. We will continue to add new tools sequentially.

Feature Addition

Released Chrome Extension "MolSketch Structure Capture"

We have released a Chrome extension that allows you to open chemical structures on web pages and papers in MolSketch Editor as editable structures just by dragging to enclose them. https://chromewebstore.google.com/detail/gggmpmbhhjgingfpkfagglnlgabomhhg?utm_source=item-share-cb

Feature Addition

You Can Now Share the Chemical Structure Being Edited via Link

You can now generate a shareable link for the structure you are editing and share it directly with others. Please use this feature to review and exchange structures.

Feature Addition

Structural Formula Conversion Tool Released

We have released a tool page that can generate structural formulas from SMILES, CAS numbers, compound names, images, and handwriting. The generated structural formulas can be copied, saved, and further edited in the editor.

Feature Addition

You can now adjust the thickness of joints

You can change the thickness from the joint settings. You can adjust only the selected joints or set the thickness for newly drawn joints.

Feature Addition

Added New Types of Arrows

Added thick arrows, dashed arrows, cancellation arrows, and more. You can now create reaction equations and equilibrium expressions more freely.

Bug Fix

Improved Bond Display

Reviewed the bond exclusion area around atoms, making the structural formulas look cleaner.

Bug Fix

Fix for Structure Reset When Switching Languages

Fixed a bug where the structure being edited was reset when changing the display language.

Feature Addition

Support for Polymer Notation Added

Polymer notation indicating repeating units in chemical structures can now be added. It can be used in reaction schemes and structural representations of materials and polymers.

Feature Addition

Structure Check Feature Added

You can now automatically check if the created structure has any problems.

Feature Fix

Improved SMILES Output

We have made it possible to output SMILES that more accurately reflect the structure.

Feature Update

Addition of Usage Limits for AI Features

The use of OCR and handwriting recognition features while not logged in has been limited to 3 times per day. By logging in, you can continue to use all AI features without any limit.

Feature Addition

Support for Export in PowerPoint Format

You can now download created chemical structures in PowerPoint (.pptx) format. The structural formulas can be edited directly in PowerPoint and can be used as-is in presentation materials.

Functional Fix

Corrected Charge Display to Common Notation

The display of charges added to atoms has been changed from the conventional "+2" and "-2" to the more common notation "2+" and "2-". This will make the representation of chemical formulas and individual ions clearer and more standard. There is no impact on the structural data itself.

Bug Fix

Correction of Structural Formula Templates

There were several errors in the structural formula templates, such as amino acid structures, so they have been corrected.

feature fix

Support for Aromatic SMILES Input

In addition to the Kekulé form, aromatic SMILES input is now supported. This allows not only C1=CC=CC=C1 but also aromatic SMILES such as c1ccccc1 to be correctly read.

Feature Update

Addition of Sharing Methods

We now support sharing the site via LinkedIn, WhatsApp, Email, and QR code. Please share your MolSketch with many people!

Support for Exporting as SMILES

We have added a feature that allows you to export the SMILES of the structures you create. Please note that this feature is a simplified version, so the SMILES may not always be as expected. Please review and modify the output results as necessary before use.

Added Login Feature

We have added a login feature. This allows for the persistence of creation history and the ability to share data across different browsers and devices.

Addition of Notification Feature

We have added a notification feature. From now on, update information and more will be delivered through this.
