California SB 574
California's new AI rules for lawyers, and where Sidebar fits
SB 574 was signed in September 2026 and takes effect January 1, 2027. It adds Business and Professions Code section 6068.1 and amends Code of Civil Procedure section 128.7.
What the law asksHow Sidebar handles it
The lawKeep confidential, nonpublic and personally identifying client information out of public generative AI.
SidebarA private, encrypted workspace for your firm. GPT-6, Claude Opus 5.5 and Gemini are reached only over channels covered by written zero-retention terms, and nothing you enter is used for training.
The lawTake reasonable steps to verify AI output, and personally read and verify every citation in a court filing.
SidebarEvery case citation is checked against the published opinion, with the quoted passage shown beside it, so reading and confirming each one takes seconds, not an afternoon.
The lawThe lawyer stays responsible. AI can assist, but the practice of law cannot be handed to it.
SidebarSidebar researches and drafts; you decide. Answers link the sources they rely on, so your review starts from the record.
A summary, not legal advice. Sidebar does not certify compliance with SB 574; read the statute and State Bar guidance for your practice.
The two questions lawyers ask first
Is it confidential? Are the cases real?
Confidentiality
Client confidences stay confidential.
Consumer AI plans can keep what you paste. Sidebar reaches every model only over channels covered by written zero-retention terms, so nothing you send is stored by the model provider or used for training. Your work is stored encrypted in your firm’s workspace.

Every citation checked before you see it.
Courts are sanctioning lawyers for AI-invented cases. Sidebar matches every citation to the real opinion, shows you the passage that supports it, and removes anything it cannot find. You still read what you cite.

Rule 1.6 and ABA Formal Opinion 512 already require you to protect what you paste. In United States v. Heppner (S.D.N.Y. 2026), documents created with consumer AI tools were found unprotected by privilege, the court drawing a line between consumer products and enterprise tools with contractual confidentiality and zero data retention.

Why Sidebar exists
Big firms got frontier AI first. Now it's your turn.
Secure, citation-checked AI has been sold to firms with dozens of seats and procurement teams. Sidebar gives the same setup to one attorney, for one monthly price.
Drafts and revisions come back as a formatted Word document, not markdown in a chat window.

Questions lawyers ask
Before you paste anything.
Yes, the same models at full strength. What Sidebar adds is matters to organize the work, research grounded in real case law, real documents out instead of chat text, and terms built for privileged material.
It can try, the way any model can. Every citation is checked against a real opinion and removed if it cannot be verified, and you can read the matched quote and open the passage before relying on it. You remain responsible for what you file.
The model providers retain nothing after processing and never train on it. Your conversations and extracted document text are stored encrypted (AES-256) in your firm's workspace. The details are in our data processing agreement and subprocessor list.
For research grounded in published opinions, no. For secondary sources and citators, that is your call, and many pilot firms run both side by side today.
Yes. Pricing is per seat with a firm admin and one bill, and you can add or remove seats month to month.
Yes. New accounts get 5 days free. Checkout asks for a card, and you are not charged if you cancel before the trial ends. After that it is monthly, per seat, and you can cancel anytime.
It keeps automated sign-ups from using the model capacity real firms rely on. You are not charged during the trial. Cancel from the billing portal before it ends and you pay nothing.
Use the AI you’re not nervous to paste into.
ChatGPT, Claude, and Gemini for research and drafting, for firms of 1 to 50. Per seat, monthly.
