Managing Duplicate Entries in Your Chronology
Last updated: February 23, 2026
Managing Duplicate Entries in Your Chronology
Quick answer: Mary automatically consolidates duplicate entries within a single processing session. When consolidation occurs, you will see a "+n" badge next to the source page label. If you still see duplicates, keep the best version and delete the others. Use relevance filters to surface the most important entries and reduce clutter.
Tip: If you want to check specific facts without scrolling through duplicate entries, try Fact Explorer. Ask Mary a direct question and she will find the answer with source references. Look for the Fact Explorer tab on your matter.
How Duplicate Consolidation Works
Mary automatically detects and consolidates duplicate entries when processing your documents. When this happens, you will see a small "+n" badge next to the source page label on the right side of an entry (for example +1 or +3). Click the badge to see all source documents that feed into that single entry.
"+n" means the same event was found in n additional source locations.
Important: Consolidation (clustering) only runs within a single processing session. If you extend your chronology by adding more documents later, Mary does not re-run consolidation across the original entries and the new ones. This means you may see entries from the new batch that look similar to entries from the original batch.
When Duplicates Do Not Consolidate
Sometimes entries that look the same will not consolidate. This can happen when:
The entries were created in different processing sessions (e.g., after extending a chronology with new documents)
The wording or context differs enough that Mary treats them as distinct events
The chronology is very large and contains entries from many overlapping documents
Why "Deleted" Entries Seem to Reappear After Extending
If you delete an entry and then extend your chronology with additional documents, you may see what looks like the same entry appearing again. These are not your deleted entries being restored. They are new entries extracted from the newly uploaded documents that happen to describe a similar event.
You can confirm this by checking the source document attribution on the entry. It will reference the new document, not the original one you deleted from.
For example, in a workers compensation matter, if both a GP referral letter and a specialist report mention the same workplace incident, deleting the entry from the GP letter will not prevent a new entry from appearing when the specialist report is processed later.
What to Do About Duplicates
Use relevance filters first. Set the relevance filter to "Very High" or "High" to surface the most important entries and hide lower-priority duplicates from your working view.
Keep the best version. If two entries describe the same event, keep the one with clearer language or better context and delete the other.
Copy useful detail before deleting. If the duplicate contains a useful detail that the keeper does not, edit the entry you are keeping and add that detail before deleting the duplicate.
Check the "+n" badge. If you see the badge, consolidation has already occurred. Click it to review all sources feeding into that entry.
Known Limitations
Consolidation has significantly improved and duplicates should be extremely minimal now. If you do notice duplicates after extending your chronology, you can manually delete the less useful version. We will endeavour to add manual merge capabilities in the near future.
If This Doesn't Resolve Your Issue
Check the source document attribution on suspected duplicates to confirm whether they come from different documents.
Use relevance filters to reduce the visible entry count and focus on the most important events.
If you are seeing an unusual amount of duplication across a single processing session (not from extending), email support@marytechnology.com with the matter name and we can investigate further.
