(Don't include 184 | the brackets!) The text should be enclosed in the appropriate 185 | comment syntax for the file format. We also recommend that a 186 | file or class name and description of purpose be included on the 187 | same "printed page" as the copyright notice for easier 188 | identification within third-party archives. 189 | 190 | Copyright [yyyy] [name of copyright owner] 191 | 192 | Licensed under the Apache License, Version 2.0 (the "License"); 193 | you may not use this file except in compliance with the License. 194 | You may obtain a copy of the License at 195 | 196 | http://www.apache.org/licenses/LICENSE-2.0 197 | 198 | Unless required by applicable law or agreed to in writing, software 199 | distributed under the License is distributed on an "AS IS" BASIS, 200 | WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. 201 | See the License for the specific language governing permissions and 202 | limitations under the License. -------------------------------------------------------------------------------- /README.md: -------------------------------------------------------------------------------- 1 | # Slides Advisor 2 | 3 | Proof-of-concept Google Workspace Add-on using Gemini to analyze and provide feedback on presentations. 4 | 5 | ## How it works 6 | 7 | The add-on uses the Slides API to extract 8 | thumbnails and speaker notes for a presentations. That information is then sent to the `gemini-vision-pro` model along 9 | with a prompt asking it to review the material based on common best practices. The feedback is presented to the user in the add-on. 10 | 11 | The demo uses a zero-shot prompting approach -- no example slides or feedback are provided. Nor has any fine tuning of the base Gemini model been performed. 12 | 13 | ## Customizing & improving results 14 | 15 | Exploration and experimentation is encouraged. There are several ways to customize the add-on and improve the quality of the feedback. 16 | 17 | * Change the guidelines in the prompt. The current guidelines are generic and cover a subset of recommendations for slides. Change the prompt to fit your own guidelines. 18 | * Switch to few-shot prompting. Providing examples of slides that adhere to your guidelines or violate them may help Gemini 19 | provide more relevant feedback. 20 | * Use a fine-tuned model. If you have a large content library with feedback, consider fine-tuning your own model for the task. 21 | 22 | ## Setup 23 | 24 | These instructions assume some familiarity with Apps Script, Add-ons, and Google Cloud Platform. 25 | 26 | 27 | 1. Create and install an add-on following the [quickstart](https://developers.google.com/apps-script/add-ons/translate-addon-sample) 28 | 1. Update the add-on source code & script manifest with the code from the `src` folder. 29 | 1. Enable Vertex AI in the Google Cloud project for the script. 30 | 1. Create a service account in the same project and grant it the `Vertex AI User` role. 31 | 1. Create and export a JSON key for the service account. 32 | 1. Set the `SERVICE_ACCOUNT_KEY` script property with the JSON key contents. 33 | 34 | Open Google Slides to try the add-on. It should appear in the right hand side panel as an eye icon. -------------------------------------------------------------------------------- /docs/code-of-conduct.md: -------------------------------------------------------------------------------- 1 | # Code of Conduct 2 | 3 | ## Our Pledge 4 | 5 | In the interest of fostering an open and welcoming environment, we as 6 | contributors and maintainers pledge to making participation in our project and 7 | our community a harassment-free experience for everyone, regardless of age, body 8 | size, disability, ethnicity, gender identity and expression, level of 9 | experience, education, socio-economic status, nationality, personal appearance, 10 | race, religion, or sexual identity and orientation. 11 | 12 | ## Our Standards 13 | 14 | Examples of behavior that contributes to creating a positive environment 15 | include: 16 | 17 | * Using welcoming and inclusive language 18 | * Being respectful of differing viewpoints and experiences 19 | * Gracefully accepting constructive criticism 20 | * Focusing on what is best for the community 21 | * Showing empathy towards other community members 22 | 23 | Examples of unacceptable behavior by participants include: 24 | 25 | * The use of sexualized language or imagery and unwelcome sexual attention or 26 | advances 27 | * Trolling, insulting/derogatory comments, and personal or political attacks 28 | * Public or private harassment 29 | * Publishing others' private information, such as a physical or electronic 30 | address, without explicit permission 31 | * Other conduct which could reasonably be considered inappropriate in a 32 | professional setting 33 | 34 | ## Our Responsibilities 35 | 36 | Project maintainers are responsible for clarifying the standards of acceptable 37 | behavior and are expected to take appropriate and fair corrective action in 38 | response to any instances of unacceptable behavior. 39 | 40 | Project maintainers have the right and responsibility to remove, edit, or reject 41 | comments, commits, code, wiki edits, issues, and other contributions that are 42 | not aligned to this Code of Conduct, or to ban temporarily or permanently any 43 | contributor for other behaviors that they deem inappropriate, threatening, 44 | offensive, or harmful. 45 | 46 | ## Scope 47 | 48 | This Code of Conduct applies both within project spaces and in public spaces 49 | when an individual is representing the project or its community. Examples of 50 | representing a project or community include using an official project e-mail 51 | address, posting via an official social media account, or acting as an appointed 52 | representative at an online or offline event. Representation of a project may be 53 | further defined and clarified by project maintainers. 54 | 55 | This Code of Conduct also applies outside the project spaces when the Project 56 | Steward has a reasonable belief that an individual's behavior may have a 57 | negative impact on the project or its community. 58 | 59 | ## Conflict Resolution 60 | 61 | We do not believe that all conflict is bad; healthy debate and disagreement 62 | often yield positive results. However, it is never okay to be disrespectful or 63 | to engage in behavior that violates the project’s code of conduct. 64 | 65 | If you see someone violating the code of conduct, you are encouraged to address 66 | the behavior directly with those involved. Many issues can be resolved quickly 67 | and easily, and this gives people more control over the outcome of their 68 | dispute. If you are unable to resolve the matter for any reason, or if the 69 | behavior is threatening or harassing, report it. We are dedicated to providing 70 | an environment where participants feel welcome and safe. 71 | 72 | Reports should be directed to *[PROJECT STEWARD NAME(s) AND EMAIL(s)]*, the 73 | Project Steward(s) for *[PROJECT NAME]*. It is the Project Steward’s duty to 74 | receive and address reported violations of the code of conduct. They will then 75 | work with a committee consisting of representatives from the Open Source 76 | Programs Office and the Google Open Source Strategy team. If for any reason you 77 | are uncomfortable reaching out to the Project Steward, please email 78 | opensource@google.com. 79 | 80 | We will investigate every complaint, but you may not receive a direct response. 81 | We will use our discretion in determining when and how to follow up on reported 82 | incidents, which may range from not taking action to permanent expulsion from 83 | the project and project-sponsored spaces. We will notify the accused of the 84 | report and provide them an opportunity to discuss it before any action is taken. 85 | The identity of the reporter will be omitted from the details of the report 86 | supplied to the accused. In potentially harmful situations, such as ongoing 87 | harassment or threats to anyone's safety, we may take action without notice. 88 | 89 | ## Attribution 90 | 91 | This Code of Conduct is adapted from the Contributor Covenant, version 1.4, 92 | available at 93 | https://www.contributor-covenant.org/version/1/4/code-of-conduct/ -------------------------------------------------------------------------------- /docs/contributing.md: -------------------------------------------------------------------------------- 1 | # How to Contribute 2 | 3 | We would love to accept your patches and contributions to this project. 4 | 5 | ## Before you begin 6 | 7 | ### Sign our Contributor License Agreement 8 | 9 | Contributions to this project must be accompanied by a 10 | [Contributor License Agreement](https://cla.developers.google.com/about) (CLA). 11 | You (or your employer) retain the copyright to your contribution; this simply 12 | gives us permission to use and redistribute your contributions as part of the 13 | project. 14 | 15 | If you or your current employer have already signed the Google CLA (even if it 16 | was for a different project), you probably don't need to do it again. 17 | 18 | Visit to see your current agreements or to 19 | sign a new one. 20 | 21 | ### Review our Community Guidelines 22 | 23 | This project follows [Google's Open Source Community 24 | Guidelines](https://opensource.google/conduct/). 25 | 26 | ## Contribution process 27 | 28 | ### Code Reviews 29 | 30 | All submissions, including submissions by project members, require review.

Do not suggest improvements if the score is 80 or above. 25 | 26 | * Simplicity -- Slides should focus on one main idea per slides and any text or images should be consistent with the idea. Slides should have either a few brief bullet points or 1 to two sentances to make an impactful statement. Score the slide 27 | lower if the main message is not clear. 28 | 29 | * Color and typography -- Slides should have consistent fonts that are large enough to read. Colors can be used for emphasis and should always have a high contrast ratio. Slides with low contrast ratios 30 | or font sizes that are too small should be scored lower. No more than 3 different fonts should be used on a slide. 31 | 32 | * Structure and whitespace -- Slides should have a clear structure and adequate whitespace to not feel cluttered or crowded. 33 | 34 | * Graphics & icons -- Bold imagery or charts to emphasize the message are encouraged and should be scored higher.
