Move your team from CoCounsel to Lexis+ AI.
Each person gets a short interview, then a personalized step-by-step guide showing exactly where their saved work, prompts, and projects land in Lexis+ AI — and the few things that need a manual step, walked through. You send one invite; nobody becomes the help desk, and nothing in CoCounsel is changed or cancelled. Want to see where you’re paying for both first? Run the free audit.
Both tools provide AI-assisted contract and document drafting grounded in authoritative legal sources and firm precedents — CoCounsel drafts from firm precedent contracts or Practical Law templates and delivers output directly into Microsoft Word via a web-to-Word pipeline; Lexis+ Protégé drafts through the Protégé AI assistant, drawing on LexisNexis sources and documents in the firm's connected Vault or DMS. To migrate from CoCounsel to Lexis+ Protégé: export your firm's precedent contracts from CoCounsel and upload them to a Protégé Vault (or connect the DMS); recreate any custom playbook instructions as Protégé custom workflow prompts. To migrate from Lexis+ Protégé to CoCounsel: upload precedent contracts to CoCounsel to generate custom playbooks; note that CoCounsel also surfaces Practical Law's 650+ standard templates, which broadens the starting-template library compared to building from scratch. In both directions, jurisdiction-aware drafting requires specifying jurisdiction in the prompt.
- Warning: CoCounsel delivers drafts end-to-end into Microsoft Word as the primary output surface; Lexis+ Protégé outputs through its AI assistant interface and requires a manual copy step to Word unless iManage/SharePoint/NetDocuments is connected.
- Warning: CoCounsel includes access to Practical Law's curated standard templates on the CoCounsel Legal tier; Protégé's template library depends on what the firm has stored in its Vault or DMS — no equivalent out-of-the-box standard template catalog is documented.
- Warning: Redlining support is explicitly part of Lexis+ Protégé's drafting capability; CoCounsel's nodes document drafting and playbook deviation-flagging but redlining as a discrete tracked-changes mode is not separately documented — verify with each vendor before switching if tracked-changes redlining is a core workflow.
Both tools perform AI-driven review of uploaded legal documents — CoCounsel processes batches of thousands of documents simultaneously returning sortable, filterable tables of extracted information and flags conflicts against loaded playbooks; Lexis+ Protégé handles documents organized in Vaults (up to 50 vaults, each 1–500 documents) and performs summarization, key citation extraction, risk identification, and missing-authority detection. To move from CoCounsel to Lexis+ Protégé: download your existing document sets from CoCounsel, organize them into Vault groupings by matter in Protégé, then connect to iManage/SharePoint/NetDocuments if your firm uses a DMS to avoid re-uploading repeatedly. To move from Lexis+ Protégé to CoCounsel: upload documents through the CoCounsel web interface and apply the relevant playbook to replicate the risk-flagging workflow that Protégé's risk-identification step provides.
- Warning: CoCounsel supports batch analysis of thousands of documents in a single run; Lexis+ Protégé Vaults cap at 500 documents per vault, so very large discovery or due-diligence sets must be split across multiple vaults.
- Warning: CoCounsel returns results as sortable, filterable tables optimized for due-diligence workflows; Protégé surfaces findings through a conversational AI interface — the output format difference requires workflow adaptation for teams accustomed to spreadsheet-style review outputs.
- Warning: Document history and AI-generated annotations are not portable between platforms; export summaries or flag reports from the outgoing tool before decommissioning access.
Both tools answer legal research questions in natural language against authoritative primary law databases — CoCounsel grounds answers in Westlaw (150+ years of case law, statutes, secondary sources) with KeyCite citation flags; Lexis+ Protégé grounds answers in LexisNexis primary law plus 25+ practice-area secondary sources with Shepard's validation. To migrate from CoCounsel to Lexis+ Protégé: re-run research queries in Protégé's conversational interface; your research history does not transfer, so export or copy prior CoCounsel research summaries to a document vault before cancelling. Switching from Lexis+ Protégé to CoCounsel: set up the CoCounsel Legal web interface, then use the Deep Research feature for multi-step, survey-of-law queries that parallel Protégé's conversational mode. On either side, authority validation is automatic in-line (KeyCite on CoCounsel; Shepard's on Lexis+).
- Warning: CoCounsel's Deep Research (multistep AI planning) is available only on the CoCounsel Legal tier; CoCounsel Essentials has more limited research depth. Verify your subscription before comparing feature parity.
- Warning: Lexis+ Protégé lets users toggle between Legal AI mode (LexisNexis-grounded) and General AI mode (multiple LLM providers); CoCounsel does not offer an ungrounded 'general' mode — all answers are Westlaw-sourced.
- Warning: Research history, saved queries, and annotated results are siloed in each platform and cannot be exported in a structured format; plan for a transition overlap period where both products run in parallel to avoid losing active research threads.
Both products support litigation workflows, though from complementary angles — CoCounsel Legal provides end-to-end AI assistance for litigation tasks (complaint analysis, discovery batch review, event chronology, agentic strategy workflows integrated with Westlaw and Practical Law); Lexis+ Protégé's litigation analytics module surfaces data-driven intelligence on judges, courts, opposing counsel, win/loss rates, and motion outcomes to inform strategy. When adding Lexis+ to a CoCounsel-led litigation workflow, use Lexis+ Litigation Analytics early in matter intake to benchmark the judge and opposing counsel before using CoCounsel for document review and drafting. When moving off CoCounsel litigation support toward Lexis+ as the primary tool: use Protégé pre-built litigation-preparation workflows for brief and motion drafting and configure the Vault with matter documents; rely on Litigation Analytics for strategy intelligence that replaces CoCounsel's Westlaw-integrated case assessment.
- Warning: CoCounsel's litigation support is available only on the CoCounsel Legal tier (not Essentials); confirm tier before planning a migration that depends on agentic litigation workflows.
- Warning: Lexis+ Litigation Analytics' jurisdictional coverage varies by subscription scope and is negotiated per enterprise contract for larger firms; solo/small-firm plans purchased online may have narrower coverage — verify before relying on it for a specific court or jurisdiction.
- Warning: CoCounsel integrates Practical Law's litigation guides and checklists directly; Lexis+ does not include Practical Law content — firms moving from CoCounsel to Lexis+ must source equivalent practice guides elsewhere or maintain a separate Practical Law subscription.
Both tools allow firms to encode their own processes and standards into reusable AI workflows — CoCounsel generates custom playbooks from uploaded firm precedent contracts and applies them during document analysis and drafting to flag non-standard language; Lexis+ Protégé provides a no-code workflow builder where teams build custom multi-step AI workflows (research, drafting, review, litigation preparation) drawing on the firm's Vault and DMS. To move playbook logic from CoCounsel to Protégé: export or document the key deviations each playbook flags, then encode those as instructions or workflow steps in Protégé's custom workflow builder; upload the underlying precedent contracts to a Protégé Vault so the AI can ground answers in them. To move from Protégé workflows to CoCounsel: upload the precedent contracts driving each workflow to CoCounsel's playbook generator; replicate multi-step workflow sequences as separate CoCounsel tasks chained manually or via agentic workflow features on the Legal tier.
- Warning: CoCounsel playbooks are auto-generated from uploaded precedent contracts and are applied automatically during batch document review; Protégé custom workflows are built step-by-step in a workflow builder — the mental model and authoring effort differ significantly, requiring workflow redesign rather than a direct import.
- Warning: Practical Law's 650+ expert-curated playbooks are available out of the box in CoCounsel; Protégé ships pre-built workflows for common tasks but does not include access to Practical Law content, so firms lose that curated library when moving to Lexis+.
- Warning: CoCounsel playbook flagging runs automatically across batch document analysis without per-document setup; Protégé workflows may need to be explicitly triggered per matter or document set — check whether the custom workflow builder supports automatic batch application before assuming equivalent behavior.
