Clean up duplicates without guessing.

Attio already lets you merge People and Companies. Neon Deer adds an Attio workspace scan, configurable matching rules, grouped review, AI-assisted prioritization, saved false-match exclusions, and bulk merge approvals. It uses Attio’s merge operation when you approve a merge. If you only have one known pair to combine, Attio’s native merge may be enough.

Duplicate Detection scans and merges People and Companies, not Deals, custom-object records, or duplicate list entries. Matching rules can use related custom-object data as evidence when comparing People or Companies.

Yes, when another matching rule connects the records. For example, combine a similar person name with the name of their linked company, or compare company domains after subdomain normalization. Similar-name matching is available for names; other field comparisons use normalized exact values. A shared company or email domain alone does not prove two people are the same. Choose matching rules.

Choose the record whose values should take priority and inspect the merge preview for conflicts. Attio combines the originals into a new record with a new ID and URL. The selected record determines value priority; it does not keep its original ID. Review the result before relying on saved record IDs in another tool. Read the merging guide.

No. It finds potential duplicates already in Attio, including checks on new or updated records. It does not block an import or form submission. Schedule scans to catch new duplicates, and approve the merges you want to make. Set a scan schedule.

Yes. Score selected duplicate sets or all sets matching your filters, including results beyond the current page. Filter by a minimum AI score, such as 80 or 90. A set appears when at least one candidate meets that score; review the other candidates and conflicts before approving the group. Approve the matches you trust in batches. Rescan and refresh scores to review further matches. Scores are estimates, not calibrated probabilities or automatic merge approvals, and scoring uses your plan’s AI allowance.

Yes. Scheduled duplicate scans are included on Free and Paid. Each full scan of People or Companies uses one scan from the same allowance as a scan you start yourself. Check your plan’s monthly allowance before choosing a daily, weekly, or monthly schedule. See scan allowances, trial limits, and add-ons.

Finding duplicates does not merge your records. Review the results and approve the merges you want to make.

Those two records stop being flagged as duplicates of each other in later scans and automatic detection. Your team can remove the exclusion from the Not duplicates page. Either record can still match a different record. See how exclusions work.

It saves every original record’s field values and relationships, plus the IDs of related notes, comment threads, tasks, list entries, files, meetings, and recordings. It also captures references from other records and list-entry attributes pointing to those originals. Related-item contents are not copied. Before approval, the confirmation lists related-data categories outside your connection’s granted permissions. See backup coverage.

Yes. Backups are on by default and disclosed before approval, but your team can turn them off or skip a running backup if your data policies require it. Turning backups off deletes saved backups for the organization. Completed merges cannot be undone, with or without a backup. See backup controls.

No. Matching rules and record comparisons work without AI scoring. Paid plans include an AI allowance if you want help prioritizing duplicate sets.

Your billing tier counts records across all objects in your connected Attio workspace. Duplicate scans and merges run on People and Companies. See pricing and the scan docs for details.
