Claustar is a “context-first” AI document preparation platform for business contracts. Users describe a transaction or employment scenario in natural language, and the system asks targeted follow-up questions to fill in key details. It then generates a structured draft based on lawyer-reviewed templates, marking missing facts clearly with [MISSING] instead of guessing. The platform explicitly states that it is not a law firm and does not provide legal advice.
Claustar covers a lightweight contract workflow from drafting to signing: AI Q&A-based drafting, risk alerts, structured templates, AI clause editing, DOCX/PDF export, multi-party e-signatures, and a single workspace for managing documents, signers, and status. It currently supports employment agreements, IP assignments, service agreements, NDAs/confidentiality agreements, freelance and client contracts, and similar document types. For team collaboration, the site mentions projects, signers, status tracking, and Business/Enterprise capacity for teams, but does not disclose role-based permissions, approval workflows, audit logs, or SSO.
Pricing is fairly clear: Pro costs US$39/month and includes 20 documents/month and 10 active projects; Business costs US$79/month and includes 100 documents/month and 25 active projects. Both plans include exports, AI editing, and e-signatures. Annual billing comes with a 20% discount. Enterprise is custom-priced, with emphasis on custom capacity, workspace limits, onboarding, and dedicated support. New accounts can start with a Pro trial without a credit card, and first-time Pro/Business subscriptions come with a 7-day refund policy.
On security, Claustar states that contract content is not used to train AI models, that users retain ownership of their content, and that encryption is provided both in transit and at rest. Based on the available description, deployment appears to be cloud-based SaaS, with no self-hosting option mentioned. APIs, webhooks, third-party integrations, compliance certifications, and similar capabilities are not publicly disclosed, so companies that need deep integration into internal business systems should verify these points further.
Its strengths are a low learning curve, an end-to-end workflow, and transparent pricing, making it a good fit for startups, SMBs, freelancers, and service teams handling standard contracts. Its limitations are that complex, high-risk, or cross-jurisdictional disputes still require lawyer review, and information on template coverage and enterprise-grade controls is limited.
Mainland China access, payment methods, and local compliance information are not disclosed, so their status is unknown. If local e-signatures, contract circulation, and compliance are important, compare it with 法大大, 上上签, e签宝, and similar providers. If you only need initial English contract drafts, Claustar can be evaluated as an overseas contract drafting tool.
