- Do review all outputs before sending/filing
- Do maintain organized folder structures
- Do back up important documents before processing
- Do document your workflows for team replication
Don'ts
- Don't automate privileged analysis without controls
- Don't rely on Cowork for final legal conclusions
- Don't process client documents without proper security
- Don't skip verification of extracted data
- Don't use for regulated workflows without compliance review
Quality Control Checklist
For every Cowork-generated deliverable:
- Spot-check extracted data against source
- Verify document formatting is correct
- Review any legal conclusions
- Check privilege/confidentiality handling
- Confirm file saved to correct location
- Test any Excel formulas
- Review before client/counterparty sharing
Part 13: Limitations and Workarounds
Current Cowork Limitations
| Limitation | Workaround |
|---|---|
| Desktop for macOS only (current preview) | Verify release notes before planning cross-platform rollout |
| Research preview risk profile | Use approval checkpoints and human review before external sharing |
| No projects support in Cowork | Organize work by folder and task-specific runs |
| No memory across Cowork sessions | Include matter context in each new run |
| Not captured in Audit Logs/Compliance API/Data Exports | Do not use for regulated workflows requiring those controls |
| App must stay open during runs | Prevent sleep/closure during long tasks |
| File size limits | Split large documents |
| Complex formatting | May need manual polish |
When to Use Traditional Approach Instead
- Highly confidential matters (privilege concerns)
- Regulated workflows requiring audit trails
- Complex formatting requirements
- When human judgment is critical
- One-off tasks that don't justify setup
Do This Now
- Set up Cowork on your Mac and create a working folder for legal documents
- Process a batch of 5–10 documents (e.g., NDAs or contracts) with Cowork
- Generate one professional document (Word, Excel, or PowerPoint)
- Extract tabular data from documents into Excel
- Create a track-changes document with comments for one contract
