Post-Casetext replacement
Casetext was acquired by Thomson Reuters in 2023, and the standalone Casetext route now points into CoCounsel. The replacement problem for solos is not only finding another AI chat box; it is keeping source links, citation checks, matter context, and review records together before a filing leaves the office.

Migration FAQ
Start with the replacement workflow that preserves source links, citation status, matter context, and review notes. A tool list is not enough if the old memo cannot be reconstructed from public authority.
Score each candidate on four migration dimensions: source portability, citation-risk controls, proprietary-content dependency, and audit-trail retention. That keeps the decision tied to filing risk rather than demo polish.
Treat old AI-assisted text as unverified work product until the cited authorities reopen cleanly and still support the proposition. Reuse the research question, not the unchecked citation string.
Use enterprise research when a matter requires proprietary citators, treatises, Practical Law content, or firm-approved workflows. CiteCanon is meant for source-first verification and drafting hygiene, not a waiver of professional review.
Source portability
Research packets favor CourtListener, Cornell LII, govinfo, and eCFR routes a lawyer can open outside the product.
Citation policy
Unsupported citation-shaped text is flagged or blocked instead of polished into final output.
Audit posture
The migration path keeps source links, session ids, and review checkpoints separate from generated prose.
