NDA
AI NDA review in plain English
Non-disclosure agreements look standard until you read the fine print. Pinnacle scans every clause for scope creep, one-sided obligations, and missing carve-outs — so you know what you're agreeing to before you sign.
Key takeaway
An NDA should protect specific confidential information for a defined period — not lock up your prior knowledge, public facts, or ability to work in your field.
Who should review a nda?
Sign an NDA before a job interview, investor meeting, vendor evaluation, or freelance kickoff? You should read it — even "standard" NDAs can restrict what you can say, build, or work on afterward. A quick review helps you understand the scope before you share anything sensitive.
Common red flags we catch
- ⚠Confidentiality scope that covers public information or your prior work
- ⚠Perpetual or multi-year obligations with no sunset date
- ⚠One-sided indemnification for breaches you didn't cause
- ⚠Broad definition of "confidential information" that includes your own ideas
Key clauses explained
Definition of confidential information
This is the heart of the NDA. Watch for definitions so broad they cover your existing knowledge, publicly available data, or information you develop independently. A reasonable NDA excludes information that is already public or known to you before disclosure.
Mutual vs. one-way obligations
One-way NDAs bind only the receiving party. If both sides share sensitive information, the obligations should be mutual. Asymmetric NDAs are common when only one party discloses — but make sure that matches the reality of your deal.
Term and survival period
Confidentiality obligations should have an end date — typically 2–5 years for business information, sometimes longer for trade secrets. Perpetual obligations without carve-outs are a red flag unless you're truly handling highly sensitive IP.
Permitted disclosures
Most NDAs allow disclosure when required by law, court order, or to professional advisors under similar confidentiality terms. Missing these carve-outs can put you in an impossible position if you're legally compelled to disclose.
Residuals and residual knowledge
Some NDAs add a residuals clause allowing use of information retained in unaided memory. That can be reasonable for high-volume reviews — or dangerously broad if it swallows the confidentiality promise. Read residuals language carefully.
What we review in your nda
- Mutual vs. one-sided confidentiality obligations
- Carve-outs for publicly known or independently developed information
- Term length and survival period after the agreement ends
- Return-or-destroy requirements for shared materials
Pre-sign checklist
- ✓Is the NDA mutual if both parties are sharing information?
- ✓Does the definition exclude public information and prior knowledge?
- ✓Is there a clear term limit on confidentiality obligations?
- ✓Are return-or-destroy requirements reasonable and time-bound?
- ✓Can you disclose to your lawyer or accountant under confidentiality?
- ✓Does residuals or non-compete-like language go beyond confidentiality?
Annotated example clause
Example one-way NDA definition (fictional)
Confidential Information means any information disclosed by Disclosing Party, whether oral or written, including all business, technical, and financial information, and any information Recipient creates that relates in any way to Disclosing Party’s business. Obligations survive indefinitely.
“any information disclosed … whether oral or written”
Extremely broad — can cover casual conversation with no marking requirement.
“any information Recipient creates that relates in any way”
Can claim ownership-like control over your independent work product.
“Obligations survive indefinitely”
Perpetual terms are hard to manage; prefer a defined term plus trade-secret carve-outs.
Drafting-party friendly
Broad one-way definition, oral disclosures covered, perpetual survival, limited exclusions.
Balanced
Mutual NDA, written or confirmed disclosures, 3-year term, standard exclusions including prior knowledge and independent development.
Counterparty friendly
Narrow definition limited to marked written materials, short term, strong residuals and advisor carve-outs.
Worked examples
Interview NDA vs product NDA
A candidate is asked to sign an NDA before a hiring interview that shares roadmap slides.
Takeaway: Scope should cover interview materials, not a permanent ban on working in the industry or using general skills.
Vendor evaluation
Two companies exchange pricing and architecture details during a POC.
Takeaway: Use a mutual NDA with a clear term and return/destroy duties when the evaluation ends.
Common pitfalls
- Signing a one-way NDA when you will also disclose sensitive information
- Accepting perpetual confidentiality with no public-information carve-out
- Missing that "affiliates" or "representatives" expand who can receive your data
- Confusing confidentiality with a non-compete that limits where you can work
Negotiation tip
Ask to narrow the definition of confidential information and add a clear term limit (e.g., 2–3 years) with standard exclusions for public data and prior knowledge.
Negotiation moves to consider
- Ask for mutual obligations if both sides will share information.
- Narrow the definition and add standard exclusions (public, prior knowledge, independent development).
- Cap the confidentiality term and keep trade-secret rules separate if needed.
- Add advisor and legal-compulsion disclosure carve-outs.
When to contact an attorney
- NDAs bundled with non-competes or broad invention assignment
- High-stakes M&A, fundraising, or regulated-data disclosures
- Threats of enforcement or unclear trade-secret exposure
Frequently asked questions
Should I sign an NDA before a job interview?
Many employers ask for NDAs before sharing product details or strategy. Read the scope — it should cover interview materials only, not your prior work or general industry knowledge. If it feels overly broad, ask for a narrower version before signing.
What's the difference between an NDA and a non-compete?
An NDA restricts how you use or share confidential information. A non-compete restricts where you can work after the relationship ends. They often appear together in employment contexts but serve different purposes.
Can an NDA prevent me from working in my field?
A well-drafted NDA shouldn't. It protects specific confidential information — not your general skills or experience. If the language effectively blocks you from using your expertise, that's closer to a non-compete and worth pushing back on.
Do I need a lawyer to review an NDA?
For short mutual NDAs with standard exclusions, many people do a careful self-review first. Get counsel when the NDA is one-sided, perpetual, tied to employment restrictions, or covers highly sensitive regulated data.
