Subject: Moving to One Project Tracker Hi team, To make planning, coordination, and reporting simpler, we are merging our two current project trackers into a single shared tool. Beginning next Monday, all project updates, tasks, timelines, risks, and dependencies should be maintained in the new consolidated tracker. This change is intended to reduce duplicate work, eliminate conflicting information, and give everyone a clearer view of priorities across the team. Instead of checking multiple locations for status updates, owners, or deadlines, we will have one reliable source of truth. Over the next few days, the project operations team will migrate active items from both existing trackers. Please review your assigned projects by Friday and make sure task owners, due dates, status notes, and key milestones are current. If anything is missing or outdated, please update it before migration begins. The new tracker will include familiar views for individual work, team priorities, upcoming deadlines, and leadership reporting. We will also share a short guide and schedule optional office hours for anyone who would like help getting started. Please stop creating new items in the old trackers after Friday at 5:00 p.m. They will remain available in read-only mode for reference during the transition, but all ongoing work should move to the new tool starting Monday. Thank you for helping us make this transition smooth. A single tracker will help us spend less time reconciling updates and more time delivering results. Please reach out to me or the project operations team with questions, migration concerns, or suggestions as we roll this out. Best, [Your Name]

How to read these scores

Each detector's result is converted to a human-likelihood score between 0 and 1. A score of 0 means the detector is sure the text is AI. A score of 1 means it is sure the text is human. Dots are green at 0.50 or above and red below. Hover a dot to see its exact score. The 0.50 cut-off only sets the dot colors. A tool's bypass rate on the leaderboard takes the median of the 7 detector scores for each test, then averages those medians. That gives a continuous number, so it will not match the share of green dots. The same goes for each per-detector rate. It is the average of that detector's scores (the number detector pages rank by), not a count of green dots.

Humanized outputs

Tools that passed more detectors come first. Ties are broken by overall rank this cycle. Each card shows the 7 detector scores, then the tool's rewrite.

Project Tracker Consolidation Hello Team, As part of simplifying our planning and reporting processes we are going to consolidate our two trackers into one. From next Monday all information relating to your project updates, tasks, timeline, risks and dependencies will need to be logged in the new tracker. This will mean no duplication of work, confusion and everyone will have a better overview of our priorities. All project owners will know where to find their project information. Over the coming days our project operations team will move any active items from the trackers. Please ensure by Friday that all your projects have up to date task owners, due dates, comments and key milestone. Please update any missing / outdated information. The new tracker will have all the same views including personal, team priorities, deadlines and reporting to leadership. We will also provide a quick guide and optional office hours. Please do not create any new items in the old trackers after 5pm on Friday. The old trackers will still be accessible but will be read only. All work should be moved to the new tracker from Monday. Thanks for helping us with this. Having just one tracker will mean we will save time on reconciling updates. Please get in touch with me or the project operations team if you have any questions, concerns or suggestions. Best, [Your Name]

Subject: Transition to a Single Project Tracker Dear team, To make reporting, planning and coordination easier, we want to combine our two project trackers into one. Starting next Monday, project milestones, risks, timelines, tasks and updates will go into this single tracker. We believe one tracker will avoid conflicting information between the two, cut down on redundant work and help everyone better see priorities across the team. Instead of looking in two places for deadlines, status, owners and other information on our projects, we could all go to the same source. Over the next few days, the project operations team will be moving items from both of our existing project trackers into this new one. Please check your projects by Friday to make sure due dates, status, key milestones and owners are up to date. If they aren't, please correct them before we move forward. In the new tracker, you'll find views of priorities for the team, individual work, deadlines and reporting to leadership. And we'll post a quick guide to using it. We'll also offer optional office hours for anyone who wants help using it. Please don't add new items to our old trackers after 5 p.m. on Friday. They'll stay up in read-only mode for reference as we move forward, but going forward all project work should go into the new tracker, starting Monday. Thanks for helping make this change as smooth as possible. With just one tracker, we could spend less time trying to bring information together from two sources, and more time producing results. If you have questions about this change, concerns about migrating items or ideas for improving it, please let me or the project operations team know. Sincerely, [Your Name]

## Subject: Moving to One Project Tracker Hi team, To reduce duplication of work, remove confusion and make planning, coordination and reporting easier, we are consolidating two trackers to one shared project tracker. Starting from next Monday, updates to projects, activities, milestone, risks, dependencies and tasks need to be entered into the new tracker. This change will ease redundancies, prevent discrepancies and provide clarity of priorities for all team members. No more having to visit all these sites to get an update on something. There will be one 'single source of truth'. In the coming days, the project operations team will deprecate active items from the current project trackers. Take a moment before this happens and ensure your projects are up to date, including owners, due dates, status notes, and relevant milestones. Do so by Friday. You'll find familiar views in the new tracker for personal work, team priorities, upcoming deadlines, and reporting to leadership. We will provide a brief guide and hold optional office hours if anyone would like help in getting started. Please do not add new items to the old trackers after 5:00 on Friday. They'll be there in a read-only state for reference as we make the switch, but every ongoing task will now take place in the new tool, starting Monday. Thanks for helping us get this right the first time. One tracker will save us hours of combining and allow us to focus on what's important - the results! Feel free to contact me or the project operations team with any questions, migration challenges, or suggestions you have along the way. Best, ## [Your Name]

Subject: Moving to One Project Tracker Hi team, We will combine the two project tracking tools that we use today to simplify how we plan, coordinate and report on projects. All project updates, tasks, timelines, risks, and dependency updates should be entered into the single combined tracker starting next Monday. The purpose of this change is to prevent duplication of efforts, eliminate inconsistencies in data, and allow each member of the team to see what is important to other members. Rather than looking up priority, status update, owner, and deadline information from various sources, you can now find it all in one place. For the next few days, the Project Operations Team will move all of the open items from both of the current tracking systems. Please go through your list of projects by Friday and confirm that each of the task owners, due dates, status updates and major milestones are up to date. If any information is missing or out of date, please take action to update it prior to the migration process. The new tracking tool will feature the same views as before, such as: Individual Work, Team Priorities, Upcoming Deadlines, and Leadership Reporting. In addition to these views, we are creating a brief guide and scheduling optional office hours for users who may need assistance with setting up the tool. Beginning Friday, April 19th after 5:00 PM EST, please refrain from adding new issues to your current tracking tools. Your old tracking tools will continue to be accessible in a "read-only" state so that you can use them as a reference point while we transition into the new tool. All future issue tracking should take place within the new tool beginning on Monday, April 22nd. We appreciate your support during this process. One tracking tool allows us to use less time on updating records and more time producing results. If you have questions about the migration process, concerns with it, or ideas about how we can implement this, please contact either myself or the project operations team. Best, [Your Name]

Subject: Transitioning to One Project Tracker Hello all, In an effort to simplify planning, coordination, and reporting processes, we will consolidate our two current project trackers into one. Starting next Monday, we are moving all information related to projects such as updates, tasks, schedules, risks, and dependencies to one consolidated tracker. This will help us eliminate redundant processes, avoid conflicts, and make information easier to access. Instead of looking for updates and details in multiple places, we will now have one reliable source of truth. In the next few days, the project operations team will transfer all open issues from the two current trackers. Please make sure that the information about all the projects that you are responsible for is up to date by Friday. Make sure the information on task owners, deadlines, status updates, and other milestones are accurate. Our consolidated project tracker will include the same views for personal, team, deadline, and management reports. We will distribute a brief user guide and also schedule optional office hours for any help you might need. Please stop creating any new information in our current trackers after Friday at 5:00 p.m. The current trackers will still be accessible only for viewing purposes, however, starting next Monday, we will be working in one tracker only. Thank you for your cooperation. Consolidation of trackers will help us allocate more time to achieving results rather than reconciling changes and updating information. Please contact me or the project operations team if you have any questions regarding migration process. Best, [Your Name]

Subject: Moving to One Project Tracker Hi team, To simplify planning, coordination and reporting, we are integrating our two existing project tracking systems into a single shared tool. Beginning next Monday, all project progress, tasks, timelines, risks and dependencies must be reflected in the consolidated system. This will reduce redundant work, eliminate conflicting information and provide greater visibility of priorities throughout the team. Instead of accessing multiple sources for information on status, owners and deadlines, we will have a single source of accurate information. During the next several days, our project operations staff will transfer active items from both existing tracking systems. Review your assigned projects by Friday and confirm that information on owners, due dates, status and major milestones is current. Correct any deficiencies or inaccuracies before initiation of the migration. The new tracking system will support familiar formats for individual work, team priorities, upcoming deadlines and reports to leadership. Plus, we will provide a brief guide and arrange optional sessions to assist those who require help with initial implementation. Discontinue creation of new items in the old tracking systems after 5:00 p.m. on Friday. These items will be available in read-only mode for reference during the transition, but all subsequent work must be entered into the new system beginning on Monday. Our efforts to achieve a smooth transition will be greatly appreciated. Using a single system will reduce the time required to reconcile information and increase our ability to deliver results. Contact us or our project operations staff with questions, concerns about the transition or suggestions for improvement. Best, [Your Name]

Hi team, We’re consolidating our two project trackers into one to simplify planning, tracking and reporting. Starting Monday, please use the new project tracker for all project activity. The two old trackers will no longer accept new entries after 5pm on Friday. All current project updates, tasks, schedules, risks and dependencies should be captured in the new tracker. This is designed to reduce duplication, avoid conflicting information and provide a clear, up-to-date picture of team priorities. Rather than searching multiple places for status, owners and deadlines, we will now have one central place to look. Over the next few days, the project ops team will migrate active items from both of the existing trackers. Please check your projects by Friday and ensure all task owners, due dates, comments and milestones are up to date. If anything is missing or incorrect, please update it before migration starts. The new tracker will have the same views as the old ones for managing individual tasks, team priorities, upcoming deadlines and reporting to leadership. We will also publish a quick reference guide and host optional drop-in sessions to help people get started. Please refrain from adding any new items to the old trackers after Friday 5pm. They will still be accessible for reference purposes during the transition period but any new or in-progress work should be captured in the new tracker from Monday onwards. Thanks for helping us make this transition successful. Having one central tracker will allow us to spend less time reconciling updates and more time delivering outcomes. If you have any questions or concerns about the migration, please contact me or the project ops team. We are also happy to receive feedback to improve the new tool as we roll it out. Best regards, [Name]

Subject: Consolidating to a Single Project Tracker Hi team, We're combining our two project trackers into one tool to simplify planning, coordination, and reporting. Starting next Monday, all project updates, tasks, schedules, risks, and dependencies need to be kept in this new, single tracker. This should cut down on duplicated work, stop us from having conflicting information, and give everyone a better understanding of what's most important for the team. Instead of looking in different places for status, who's in charge, or when things are due, we'll have one go-to place for all information. The project operations team will move current items from both old trackers over the next few days. Please check your projects by Friday to make sure task owners, due dates, status updates, and important milestones are up to date. If anything is missing or not current, please update it before the move. The new tracker will have the same kinds of views you're used to for your work, team priorities, upcoming deadlines, and reports for leadership. We'll also provide a quick guide and set up optional help sessions for anyone who wants them. Please don't create any new items in the old trackers after 5:00 p.m. on Friday. They'll still be available to look at for a while, but all new work should go into the new tool starting Monday. Thanks for your help in making this change go smoothly. Having one tracker means we'll spend less time sorting out updates and more time getting things done. If you have any questions, concerns about the migration, or ideas, please get in touch with me or the project operations team. Best, [Your Name]

Subject: Moving to One Project Tracker Hi team, We're making things easier by combining our two project trackers into one. From next Monday, we'll use this new tool to keep track of all project updates, tasks, timelines, potential problems, and how different tasks depend on each other. This change will help simplify planning, coordination, and reporting for everyone involved. We're making this change to avoid doing the same work twice, get rid of confusing information, and make it easier for everyone to see what's important. Right now, we have to look in several places to find out what's going on, who's in charge, or when things are due. With this change, we'll have one place where we can trust the information is accurate and up-to-date. This way, we can save time and focus on what really matters. In the coming days, our project team will be moving all active tasks from the old trackers to a new system. Can you please take a look at the projects you're in charge of by this Friday and make sure all the details are up to date? This includes who's responsible for each task, when they're due, any notes about the status, and important milestones. If you notice anything is missing or out of date, go ahead and update it before we start the migration process. We're introducing a new tracker that will have views you're used to, like individual work, team priorities, and upcoming deadlines, as well as reports for leaders. To help you get started, we'll provide a quick guide and offer optional office hours for anyone who needs a little extra help. Please stop creating new items in the old trackers after Friday at 5:00 p.m. They will remain available in read-only mode for reference during the transition, but all ongoing work should move to the new tool starting Monday. We really appreciate your help in making this transition as smooth as possible. Having just one tracker will save us a lot of time and hassle when it comes to keeping everything up to date, and that means we can focus on getting things done. If you have any questions or concerns about the migration, or if you've got any suggestions on how we can make this work better, please don't hesitate to reach out to me or our project operations team - we're here to help and want to make sure everything goes off without a hitch as we roll this out. Best, [Your Name]
