Document intelligence built for how law firms actually work
AI contract editing with Word-native tracked changes, Matters for legal work management, Review Workbooks for document sets, playbooks for consistent review, and legal research across six databases.
The Challenge
- Contract review is manual, inconsistent, and slow
- Knowledge walks out the door when associates leave
- AI tools generate text but don't edit actual documents
- Matter context is scattered across workstreams, emails, and document lists
- Diligence findings are hard to compare consistently across document sets
- Legal research requires switching between multiple databases
- Clause standardization is informal and undocumented
Tracked changes your clients understand
Sphere produces real OOXML tracked changes. Send the reviewed document to your client or counterparty. They open it in Word and see standard Accept/Reject revision marks. No explanations needed. No new tools to learn.
- Standard Word tracked changes (Accept/Reject)
- Paragraph-level precision: insert, replace, delete
- Batch commit semantics for atomic review rounds
Playbooks preserve institutional knowledge
Your senior partners' review methodology shouldn't exist only in their heads. Sphere playbooks codify review criteria, risk thresholds, and preferred language into reusable templates. New associates follow the same methodology from day one. Approved workflows can be favorited, shared, hidden, and versioned.
- GDPR DPA Review, NDA Risk Assessment, SLA Analysis
- CP Checklist, Credit Agreement Summary, Shareholder Agreement Summary
- Custom playbooks for your firm's specializations
- Protected prompts with curation and sharing controls
Matters keep legal work together
Sphere Matters group workstreams, documents, issues, deadlines, timeline events, and AI-suggested admin updates. The agent can surface accessible same-matter context while workstream-level privacy boundaries stay intact.
- Matter-level command center above individual workstreams
- Workspace explorer for sibling workstreams and related documents
- Issues, deadlines, milestones, and AI admin review
Review Workbooks for diligence and portfolio review
Turn repeated legal questions into a spreadsheet-style review. Rows are documents. Columns are issues. Cells include cited answers, status, and reviewer context. Export CSV for client reports or closing checklists.
- Cited answers for each document-question cell
- Regenerate individual answers without rerunning the workbook
- Chat over the review table and export findings
Clause bank builds institutional memory
Every approved clause your firm has negotiated becomes searchable institutional knowledge. Hybrid search finds clauses by meaning. Usage tracking shows which clauses work. Jurisdiction tags keep multi-market work organized.
Legal research without tab-switching
Search Fedlex, EUR-Lex, BGE, CJEU, ECHR, and commentary from within your document. Insert citations directly. Deep Research synthesizes multi-source analysis for complex questions.
