The problem

Consumer chatbots were never built for privileged work.

Consumer AI plans can retain what you paste and may use it for training. The moment privileged material touches that, you have a confidentiality problem under Rule 1.6, and courts have started to notice. In United States v. Heppner (S.D.N.Y. 2026), documents created with consumer AI tools were found unprotected by privilege; the court drew a line between consumer products and enterprise tools with contractual confidentiality protections and zero data retention. Sidebar is built to land on the right side of that line.

One workspace, every model

Pick the right mind for the matter.

The best model changes every few months, and it varies by task. Sidebar puts the frontier behind one login, and you can switch mid-matter. Your context and the same protections come with you.

Claude Opus 4.8
Anthropic

The close reader. Deep legal reasoning over full case files: contracts, briefs, and anywhere a confident hallucination would cost you. Sonnet 4.6 and Haiku 4.5 included for everyday speed.

Zero data retention
GPT-5.5
OpenAI

The fast drafter. Structured first drafts, summaries, and high-volume triage when speed matters more than nuance. GPT-5.5 Pro included for the hardest reasoning.

Zero data retention
Gemini 2.5 Pro
Google

The long haul. A million tokens of context for sprawling discovery sets, exhibits, and matters spanning hundreds of documents. Gemini 3.5 Flash included for quick work.

Zero data retention

A model appears in Sidebar only once it runs under zero-data-retention terms, and the lineup upgrades as the labs ship new versions. Your in-app selector always shows exactly what your workspace can use today.

The product

Not a chatbot. A workbench.

Matters, documents, and conversations live together. You watch the work happen, citations link back to the opinions they came from, and you get real Word documents out, not markdown you have to reformat.

Matter-scoped

Every conversation files under a matter. Context stays with the case: documents, instructions, and history in one place.

Citations you can check

Research is grounded in real case law via CourtListener. Each citation links to the opinion it came from, so verifying before you file is one click.

Real documents out

Formatted Word documents drafted in the workspace. Watch them compose, then download the .docx.

Built for privilege

The security layer is the product.

Every model runs through one hardened path. The protections are enforced by the workspace and documented, in detail, on our security page.

Zero data retention

The model providers behind Sidebar don't store your prompts or outputs after processing, and never use them for training. That's contractual, on every model we serve.

Encrypted in transit & at rest

TLS 1.2+ on the wire. Conversations and extracted document text are stored encrypted (AES-256) in your firm's workspace.

Isolated by firm

Row-level security partitions every firm's data at the database layer, so even an application bug can't cross tenants. Inside, work is organized matter by matter.

The attorney stays the author

Drafts and research are work product for your review. The workspace shows you what the AI did at each step, and citations link to their sources so you can verify before filing.
