NDA residuals clause
A residuals clause in an NDA says whether someone may use what they remember after seeing confidential information. In plain English, it is a memory rule.
A broad memory rule can weaken an NDA in a big way. It can turn "keep it private" into "I remembered it, so I can use it." This page explains what to look for and what to ask for.
Quick answer
A residuals clause says whether someone may reuse remembered information after seeing confidential information. In a strong NDA, there is no broad memory exception, or any memory concept is kept very narrow and limited to general skills and general know-how.
If the clause is broad, it can be used to justify reuse of specific details, technical instructions, product ideas, prompts, code, or data while claiming that no copy was kept.
Common red flags include:
- the NDA allows reuse of what someone remembers from confidential information
- the memory rule is broad enough to cover real details, not just general skills
- only one side gets the benefit of the memory rule
- the NDA allows reuse of specific facts, numbers, steps, or designs
- the NDA allows reuse of remembered code, queries, prompts, or technical recipes
- the NDA does not require proof that later work was created without using the confidential information
- the memory rule has no clear time limit
- the NDA allows remembered information to be used for AI training or analytics
- the memory rule could be used as a loophole around the main duty to keep information confidential

Glossary (quick definitions)
Definition:
The residuals clause explains whether someone may use what they remember from confidential information after seeing it.
Why it matters:
- A broad memory rule can let sensitive details leak into products, plans, engineering work, or AI systems without anyone keeping a copy.
- It can create arguments about whether later work came from memory or from confidential information.
- If the wording is too broad, it can weaken the NDA more than most people expect.
Common red flags:
- The NDA allows reuse of what someone remembers from confidential information.
- The memory rule is broad enough to cover specific details, not just general know-how.
- Only one side gets the benefit of the rule.
- The NDA allows reuse of specific facts, numbers, designs, code, prompts, or technical recipes.
- The NDA does not require proof that later work was created without using the confidential information.
- The memory rule allows AI training or analytics.
What a reasonable clause looks like:
- There is no broad memory exception at all, or it is very narrow.
- Any memory concept is limited to general skills and general know-how, not specific details learned from the other side.
- It does not override the main duty to keep information confidential.
- Any limited memory concept ends when the NDA's confidentiality duties end.
- It does not allow remembered information to be used for AI training, analytics, or later product work.
What to look for
Below are common problems people miss and what to look for.
| Red flag | Why it's risky | What to ask for |
|---|---|---|
| The NDA allows reuse of what someone remembers from confidential information. | That can become a loophole for reusing details without keeping a copy. | Remove the residuals clause or narrow it sharply. |
| The memory rule covers specific details, not just general skills or general know-how. | Specific facts, designs, prompts, or technical steps can get reused under the label of "memory." | Limit any memory concept to general skills and general know-how only. |
| Only one side gets the benefit of the memory rule. | The clause can become one-sided in a way many readers miss on a quick pass. | Remove the rule or make the NDA mutual if a memory concept is truly intended. |
| The NDA does not require proof that later work was created without using the confidential information. | It becomes hard to challenge later work that may have been influenced by what was learned under the NDA. | Require clear proof if someone wants to rely on an independent-work argument. |
| The memory rule allows AI training, analytics, or later product work. | Shared information can feed future systems or products long after the original discussion ends. | Say the clause does not allow AI training, analytics, product development, or reuse of specific details. |
Why not use ChatGPT or an AI contract assistant?
Chatbots and lighter-weight AI tools can help you review a contract faster, but they usually stop short of giving you a negotiation-ready output. For founders and business operators, the hardest part often comes after the review step: turning suggested changes into a real redline, explaining those edits clearly, and sending them back with confidence. Vesk is designed to take you further through that workflow for supported contract types.
Chatbots and AI contract assistants
- Better if you want a flexible, lower-cost starting point
- More sensitive to prompt wording and less consistent across repeated runs
- Often produce suggestions or summaries rather than a sendable package
- You still have to redline the Word document and defend the changes yourself
Vesk
- Better if you want an end-to-end NDA review, redlining, and negotiation workflow
- Designed for more consistent NDA review across repeated runs
- Benchmarks against industry-standard model agreements to help catch what matters
- Delivers a secure redline package with Word files, a negotiation brief, and a deal room

What’s included in a secure redline package
Reviewing a contract is only part of the job. You still need a clear, professional way to send changes back and explain them, especially when the other side has procurement or in-house counsel. That is often the most stressful part for founders and business operators without legal training. A secure redline package is designed to make that step more organized, more defensible, and easier to handle with confidence. A secure redline package includes:
A negotiation brief that explains and supports the requested edits
A downloadable redlined Word .DOCX file with Track Changes on
A downloadable clean Word .DOCX file with the requested edits accepted
A secure deal room link you can review yourself or share with the counterparty
