AI visibility chart annotation, so every change has a reason
Proofsource puts a marker on your AI visibility chart wherever a fix went live, and lets your team add notes, including straight from Slack. Shared reports draw the same fixes, notes and model changes as the dashboard. It is for marketers and agencies who need to explain why ChatGPT, Perplexity or Claude visibility moved, without a separate change log.

|---|---|---|---|
| Week 4 | Fix live | Otter comparison page published | Proofsource |
| Week 7 | Note | Product Hunt launch | Priya |
| Week 8 | Model change | ChatGPT answers shifted | Proofsource |

What is a chart annotation for AI visibility?
A chart annotation is a small marker on a time chart that says what happened on that day: a page went live, a pricing change shipped, a press story ran, an AI model was updated. Without annotations a line chart shows that something changed but not why, and teams waste time reconstructing history from memory, tickets and chat threads.
AI visibility needs annotations even more than web analytics. Answers from ChatGPT, Perplexity, Gemini, Copilot and other AI engines shift for reasons on your side (a fix you shipped) and on theirs (a model change). Seeing both on the same chart is how you tell one from the other.
Proofsource adds a Fix live marker on the AI Visibility chart whenever a fix it tracks goes live, and anyone on your team can add a note, in the app or from Slack with a note command or message action. The same markers appear on shared reports and drive the week-by-week work list on AI traffic, so the story stays the same wherever people read it.
How it works
Markers on your AI visibility chart for every fix that went live and every note your team adds, including from Slack, carried into shared reports.
Ship a fix
When a tracked fix goes live, a Fix live marker appears on the AI Visibility chart for that day.
Add context as a note
Add a note for launches, campaigns or press so the chart explains itself later.
Or note it from Slack
Use the note command, or the message action on any Slack message, and the note lands on the chart under your name.
Share the same story
Shared reports draw the same fixes, notes and model changes, so clients see what your team sees.

Questions about AI visibility chart annotation
What is a Fix live marker?
It is a marker Proofsource places on the AI Visibility chart on the day a fix it tracks went live, so you can see visibility before and after that change.
How do I add a note from Slack?
Use the Proofsource note command in Slack, or the message action on any message. The note is written to the brand's chart as the member who sent it.
Do shared reports show the same markers?
Yes. Shared reports draw the same fixes, notes and model changes as the dashboard charts, so clients and colleagues read the same story.
What is a model change marker?
It marks a change on the engine side, such as a new model behind an assistant, so you do not credit or blame your own work for a shift the engine caused.
Which engines does the chart cover?
The AI Visibility chart covers every engine your plan tracks, up to 10 from ChatGPT and Perplexity to Gemini, Copilot and Grok.
Can I read markers through the API?
Yes. Chart markers are available through the Proofsource API for your own dashboards.
How is this different from Profound's chart annotations?
Profound also lets teams log site changes as annotations. Proofsource places fix markers automatically when tracked fixes go live, accepts notes from Slack and carries all of them into shared reports and the weekly work list.
