The secure AI workspace
for legal teams.

Sidebar gives attorneys Anthropic's most capable Claude — paired with grounded research and a matter-aware workspace. Zero data retention from AI providers.

Data isolation by default

Your prompts are routed through enterprise AI infrastructure, not consumer endpoints. Providers do not retain inputs or outputs.

No training on your data

AI providers are contractually prohibited from using your data to train or improve their models.

Built around real workflows

Upload documents, organize by matter, and keep conversation history in your firm's encrypted workspace.

The legal landscape for AI

In United States v. Heppner (S.D.N.Y. 2026), the court found that using consumer AI tools could jeopardize attorney-client privilege.

The decision drew a distinction between consumer AI products and enterprise tools with contractual confidentiality protections and zero data retention. Sidebar is built to land on the right side of that distinction.

The most capable AI,
grounded in real sources.

Most legal AI products run smaller or older models behind a domain-specific wrapper. Sidebar runs the same frontier model the engineers building tomorrow's AI use themselves.

Frontier intelligence

Sidebar always runs on Anthropic's most capable Claude. As Anthropic ships smarter models, your firm gets them automatically — you're never working with last-generation intelligence behind a legal-flavored wrapper.

Research with real citations

Drafting needs sources. Sidebar's Research mode pulls from current legal databases, regulatory filings, and academic sources, and anchors every claim to a clickable citation. You can verify every assertion against the underlying source — not a paraphrase or a summary you have to take on faith.

What you get

A complete AI workspace with the security controls your practice requires.

Frontier model from Anthropic

Sidebar always runs on Anthropic's most capable Claude. New releases roll out automatically, so your firm is never on last-generation AI.

Grounded research

Pull from current legal databases, regulatory filings, and academic sources. Every claim is anchored to a clickable citation you can verify against the underlying document.

Document Analysis

Upload contracts, briefs, and filings. Sidebar indexes your documents so Claude can reference specific sections.

Case Workspaces

Organize conversations and documents by matter. Set case-specific instructions and search across uploaded files.

Zero Data Retention

AI providers do not store your prompts or responses. Conversations are saved only in your firm's encrypted database.

Enterprise-grade security

Row-level tenant isolation keeps every firm's data fully separated. Conversation history and documents are encrypted at rest (AES-256) and in transit (TLS 1.2+).

AI that takes confidentiality as seriously as you do

Built for attorneys who need AI without compromising confidentiality.
