This tutorial shows you how to publish AI agents to Google Workspace as Google Workspace add-ons, using Apps Script or HTTP endpoints. After your publish your add-on, your users can interact with the AI agents within their workflows.
Google has released a comprehensive new tutorial that demonstrates how to bridge the gap between complex AI agents and the daily workflows of Google Workspace users. The Travel Concierge sample uses the Agent Development Kit (ADK) to deploy a conversational, multi-agent AI directly into the Google Workspace platform.
While many AI demos focus on standalone chat interfaces, this solution stands out by implementing the agent as a Google Workspace Add-on. This means the AI isn’t just a browser tab; it is a helpful sidebar accessible directly within Gmail, Calendar, Drive, Docs, Sheets, and Slides, as well as a fully functioning Google Chat app.
Key Features for Developers
The sample provides a robust blueprint for developers looking to build “agentic” workflows. Key capabilities include:
Multi-Agent Architecture:Â The solution uses Vertex AI to manage a “Travel Concierge” that orchestrates sub-agents for specific tasks, utilising tools like the Google Maps Platform Places API and Google Search Grounding.
Context Awareness:Â In applications like Gmail, the agent can read the context of the currently selected email to help plan trips based on actual correspondence.
Rich User Interfaces:Â The add-on moves beyond simple text, utilising the Card framework to display rich widgets and interactive elements.
Cross-Platform Persistence:Â User sessions are managed by Vertex AI, ensuring that a conversation started in Google Chat can be seamlessly continued in a Google Doc sidebar.
Flexible Implementation
The Apps Script implementation demonstrates how to connect a standard Workspace Add-on to the powerful Vertex AI backend using UrlFetchApp. It serves as an excellent reference for handling synchronous execution limits and rendering complex agent responses within the constraints of the Add-on sidebar.
Whether you are looking to build a travel planner or a complex enterprise assistant, this sample provides the architectural patterns needed to bring your AI agents to where your users actually work.
In this video we build a Chat app as a Google Workspace add-on with Apps Script and extend it to other Workspace applications (Calendar, Gmail, Drive, Docs, Sheets, and Slides).
To see this new framework in action, Pierrick Voulet from the Google Developer Relations team has released a fantastic video tutorial, ‘Build a Chat app as a Google Workspace add-on with Apps Script’.
The ‘OOO Assistant’: A Practical Demonstration
The video centres on building an ‘Out-of-Office Assistant’ that can block out the user’s Calendar for the day and set a Gmail out-of-office auto-reply. The real magic is how this Chat-based logic extends into a full Workspace Add-on, available in the sidebars of Gmail, Calendar, Drive, Docs, Sheets and Slides. This is achieved with minimal code changes, primarily by configuring the appsscript.json manifest to include:
A homepageTrigger to display a UI card in the add-on sidebar.
universalActions that reuse the exact same functions (blockDayOut(), setAutoReply()) originally built for the Chat quick commands.
The video provides a complete overview of the process, and you can get hands-on with the shared code yourself. For more technical details, check out the official Extend Google Chat documentation.
This is a sample Google Apps Script designed to replace all instances of specific text within a Google Slides presentation, while simultaneously applying a desired text style. The built-in Presentation.replaceAllText() method within the Google Slides service is limited; it efficiently replaces text strings but lacks the functionality to modify text formatting during the replacement process. This limitation poses a challenge when aiming for styled text replacements. This report presents a detailed script solution that overcomes this constraint.
Have you ever needed to replace text across your Google Slides presentation but also wanted to apply specific formatting to the new text at the same time? The standard replaceAllText() method in Apps Script is handy for bulk text replacement, but it falls short when you need to control the styling – like font, size, or colour – during the replacement process.
Community contributor Kanshi Tanaike has developed a clever solution to overcome this limitation. Tanaike has shared a Google Apps Script function that not only finds and replaces text throughout all elements in your slides (including shapes, tables, and grouped objects) but also applies your desired text styles simultaneously.
The script works by iterating through the elements on each slide. When it finds the text you want to replace, it uses TextRange methods to perform the replacement and apply the specified formatting attributes, such as font family, size, colour, bold, italics, underline, and more.
This approach provides significantly more control than the built-in method, allowing you to ensure that automatically replaced text matches the exact styling you need for visually consistent and polished presentations. Tanaike’s post includes the full script, configuration details for specifying the text and styles, and sample slides showing the results.
Learn how to convert Google Slides into high-resolution PNG images using Google Apps Script. Choose between the Google Slides API and the Google Drive API based on your requirements.
Here’s a useful snippet from Amit Agarwal exploring two methods exploring how to convert Google Slides to PNG images with Google Apps Script. The first approach uses the Google Slides API to get the thumbnail images of the slides, fetch the blob of the image, and then upload it to Google Drive. However, this method has limitations including predefined fixed widths and requires two URL fetches.
The second approach uses the Google Drive API, which offers advantages like generating images with the same resolution as the original slide and requiring a single URL fetch. For both code snippets follow the source link.
Use Google Apps Script to create a custom menu that will work inside Google Sheets, Google Docs, Slides and Google Forms.
Tired of writing separate code for custom menus in Docs, Sheets, Slides, and Forms? This nifty Google Apps Script snippet by Amit Agarwal helps you build a universal menu that works across all these apps!
The solution is a small snippet which detects the context to see which of DocumentApp, SpreadsheetApp, FormApp, SlidesApp are available which then lets you switch to get the appropriate .getUI() method.

The Slides Advisor project is an open source, Google Workspace Add-On that uses artificial intelligence (AI) technology to review and give feedback on your presentations, whenever you need it. The project uses Google’s Gemini API image and text processing features to analyze your Google Slides against a set of guidelines and lets you know how you are doing against those guidelines. Even better, you can customize those guidelines to follow your organization’s recommendations, or remind you to improve your presentations based on rules you define for yourself.
We’ve all been there: scrambling to cram too much information onto a single slide. But what if you had an AI assistant to give your presentations a once-over?
The Slides Advisor is a free, open-source Google Workspace Add-on for Google Slides that uses the power of AI to analyze your presentations. It checks your slides against customisable guidelines, helping you ensure they’re clear, concise, and visually appealing.
Everything you need to get started is covered in the source post by Joe Fernandez and Steve Bazyl. One of the highlights for me is seeing how you can setup a service account to access the Gemini AI API with Google Apps Script. The post also covers how you can modify the prompt you use to get different responses from Gemini.
There have been a number of recent updates and announcements around Smart Chips and other integrations to Google Docs, as well as Sheets and Slides. Some have just gone into the Google Workspace Developer Preview Program (DPP), whilst in the case of AppSheet smart chips for Google Docs they are generally available!
AppSheet smart chips for Google Docs
Starting with AppSheet smart chips for Google Docs if you already had the AppSheet Google Docs add-on installed you already have AppSheet smart chips enabled. More details including a link to the Workspace Marketplace Add-on are included in the related Workspace Updates post. The AppSheet smart chips are great way to integrate some of your app functionality in your Google Docs.
Preview links with smart chips in Sheets and Slides
We’ve had custom smart chip link previews for Google Docs for some time, but Google have recently added the same functionality to Sheets and Slides. If you have already developed link previews for Google Docs the good news is there isn’t much more you need to do to enable these for Sheets and Slides (mostly updating your manifest). More details are included on the updated Preview links with smart chips documentation page.
Create third-party resources from the @ menu
Finally, also gone into preview is third-party resource integration which you can use to “let users quickly create resources, such as tasks, support cases, or issues, in your service right from Google Docs. The new resource is then inserted into Google Docs as a smart chip.”. You can read more in the create third-party resources from the @ menu documentation page.
In the case of the preview features a reminder that this is your opportunity to test and give feedback to Google. Links to join and provide feedback are included in the Google Workspace Developer Preview page. Enjoy!
This report introduces the method for retrieving the Emoji reactions from the comments in Google Docs files (Google Documents, Google Slides, and Google Spreadsheets) using Google Apps Script.
Here’s a clever workaround by Kanshi Tanaike for retrieving comments with emoji reactions in Google Docs, Slides, and Sheets using Google Apps Script. The process to achieve this is a little convoluted in that Google Docs, Slides and Sheets are exported in Microsoft equivalent formats, then re-imported into Google formats. To remove some of the pain the post includes sample code snippets for achieving this, which can easily be adapted.
Learn how extract all the embedded images from a Google Document or Google Slides presentation and save them as individual files in a specified folder in your Google Drive.
Often I’ll use Google Docs for drafting blog posts. With the introduction of Duet AI having a generative assistant in situ helps with the creative process. As well as text Google Docs is a really simple canvas for quickly copy/pasting screenshots. Copying content from Google Docs to WYSIWYG editors can sometimes be challenging, particularly, when it comes to images.
Next time I encounter this problem I’ll be using the script solution from Amit Agarwal, which can extract images from Google Docs and Slides and save them to Google Drive. I’m sure there are many other situations where this snippet could come in handy.
This report introduces the method for easily processing the template of Google Documents and Google Slides using Google Spreadsheet as a database using Google Apps Script. Google Spreadsheet is used as a database. Google Documents and Google Slides are used as templates. The simple method for creating new Google Documents and Google Slides using the database and the templates is introduced.
Latest Apps Script magic from Kanshi Tanaike, this time they turn their addition to an easy way to use data from Google Sheets as a ‘document merge’ for templates created in Google Docs and Google Slides. This is achieved by using the TemplateApp Apps Script library, which has lots of useful features including simply methods for sheetRangeToDocuments() as well as the ability to embeded and fixed width images from placeholders. There are some llimitations documented in the GitHub repo, as well as examples for all the methods available in the library.
