Trustworthy vs. Prisidio vs. Next of Kin Plan
Last updated: August 3, 2026
Pricing and features verified August 2026. All three companies change their plans, so check each site before you buy.
All three of these help families organize important information. They are built for different jobs, and picking the wrong one is the most common way people end up paying for something they never open again.
The question is not which app looks nicest. It is whether you mainly want a safe place to keep your documents, or something else: a plan another person could pick up and use. Not the files, but the information, access, contacts, and instructions someone would use to step in.
That second thing has a name. It is called estate readiness, and it is a different job from storage.
Here is the short version.
- Choose Trustworthy if you want an organized filing system for a household with a lot of paperwork and several professional advisors working inside it with you.
- Choose Prisidio if you want a simple, secure place to store documents and share them one at a time.
- Choose Next of Kin Plan if you want your family to know what to do, whether you are preparing your own household or helping a parent.
We build Next of Kin Plan. We have tried to describe the other two the way their own customers would.

Quick comparison
Trustworthy
Trustworthy launched in 2020 and calls its product the Family Operating System. Its category structure is the deepest of the three, and document organization is clearly the center of the product.
What it does well. The category structure is deep. IDs, money, property, passwords, insurance, taxes, legal, business, contacts. It scans and files documents automatically, and it is built so an attorney, accountant, or financial advisor can work inside it alongside you. If several professionals regularly ask you for paperwork, that alone saves a lot of email.
Where it fits less well. Its depth may be more than a simpler household uses, particularly one that does not work with multiple professional advisors. The free plan is a single member, so an actual family starts at a paid tier. And like any filing system, what you get out is what you put in. It organizes documents rather than producing instructions.
Pick it if: your household has real paperwork complexity, you already pay professionals, and you want a serious system that holds all of it in one place.
Prisidio
Prisidio is a digital vault. It has an AARP partnership, so many people find it through an AARP branded version.
What it does well. It is simple, which is a real feature. You store documents, people, places, and things. You can name a Co-Owner who helps manage the vault and a Keyholder who gains access later. Item level sharing means you can hand one person one document without opening the rest. The mobile apps are solid.
Where it fits less well. It is storage by design. There is less automation and less structure than Trustworthy, and fewer plan options. If you want something that tells your family what to do next, that is not what a vault is for. It holds what you put in it.
Pick it if: you want a well built safe place for documents without extra machinery, and price matters.
Next of Kin Plan
Next of Kin Plan is built for estate readiness. It exists because of one specific gap.
Storing a 40 page insurance policy is not the same as knowing which company to call. Families in a hard week are not reading documents. They are looking for a phone number, an account number, and a due date. So the product is built around answers first and files second.
It is for the person who holds everything. Sometimes that is an adult coordinating for a parent. Often it is the one person in a household who knows what is on autopay, which policies are active, and who to call, while nobody else does.
Where it fits less well. It is not a general document manager. If your main goal is a tidy digital filing cabinet for a household with several advisors and a large volume of paperwork, Trustworthy is built for that and this is not.
Pick it if: you want the people around you to be able to step in without scrambling.
What only Next of Kin Plan does
These are the differences that do not show up in a feature grid, because the other two are not attempting them.
- Snap a bill and it fills itself in. Photograph a bill and the company, account, amount, and due date get pulled out for you. Both other products are upload and file. For a parent who is not going to fill in a form, a camera is the difference between using something and abandoning it.
- Ten categories, set to Now or Later, per person. Your spouse can see the mortgage today. Your adult son sees professional contacts only. Life insurance waits until later. Any single item can also be shared early or held back on its own, so one awkward account never forces you to open a whole category. Sharing at this resolution is not something the others offer.
- Executor access that stays closed until it should not be. A named executor sees nothing at all. Access opens only when a trusted person you chose confirms it, from a link that requires no account of their own. Then nothing actually opens for 24 hours. You are emailed the moment it starts and can stop it with one click. That mechanism does not exist in a vault.
- Heirs property handled properly. Deeds, title status, tax parcels, and named claimants recorded per property. For families who have lived in a home for three generations without clear title, almost nothing else in this market addresses it.
- A 72 hour plan. First calls in order, the autopay list, and what to handle in what sequence. This is the output. A filing cabinet has no output.
- Medications with per item visibility. Each prescription can be shared or hidden individually, because families are not one single audience.
- Share with a professional, on a timer. Send your attorney, accountant, or advisor a read only link to just the sections you choose. No account for them to create. Expires in seven days, revocable instantly, and account numbers are never sent.
- Built for the phone your parent already uses. Big text, large buttons, and a camera step instead of a form.
On professionals specifically, both products let you bring them in. The designs are different.
Trustworthy gives an advisor an ongoing seat inside your files. Next of Kin Plan sends them a link instead. You pick which sections they see, they open it in a browser with no account and no password, and the link expires after seven days. You can revoke it instantly at any point, and you get an email the first time they open it. Account numbers are never included, even for the sections you share.
That difference matters most to the professional. An attorney reviewing your file for an hour does not want ongoing custody of your account numbers in a system they do not control. A link that opens, shows what you chose, and closes itself is the arrangement most of them would pick.
What none of the three do
None of these write your will. None of them create a trust or a power of attorney.
These platforms are not substitutes for legal advice. Wills, trusts, and powers of attorney may require an attorney depending on your circumstances and your state.
What all three do is organize the information and instructions that legal documents alone do not provide. A will names who inherits the house. It does not say which bank holds the mortgage or when the payment is due. Anyone selling you a subscription as a replacement for legal work is selling you something else.
Security: what to check on all three
You are putting account numbers, medications, and family details into one of these. Ask all three the same questions before you decide.
- Is sensitive information encrypted where it is stored?
- Is two step login required, or only offered?
- Can you control what each person sees, or is access all or nothing?
- What happens if you lose access to your own account?
- Can you export everything and can you delete everything?
Here are Next of Kin Plan's answers, so you have a baseline to compare against.
- Encryption. Sensitive fields such as account numbers are encrypted where they are stored, using AES-256-GCM.
- Two step login. Required on every account, not optional.
- Access control. Every record is protected at the database level. A family member sees only what has been shared with them, checked on every single request rather than hidden in the interface.
- Files. Stored privately. Links to open a document expire after 10 minutes.
- A permanent record. Access events are written to a log that cannot be edited or deleted by anyone, including us. If a family ever disagrees about who opened what and when, there is an answer.
- Your data. Export a PDF at any time. Request deletion at any time, completed within 30 days. Nothing is sold to third parties.
Trustworthy and Prisidio both publish security information on their own sites. Read all three before you decide. This is the right thing to be picky about.
How to choose in two minutes
- Do you mainly want documents filed, or people prepared? Filed points to Trustworthy or Prisidio. Prepared points to Next of Kin Plan.
- Do you have advisors you would want working inside the system? If yes, look at Trustworthy first.
- Is a simple secure place for documents the whole job? If yes, Prisidio is the shortest path.
- Would someone else be able to run your household next month? If the honest answer is no, that is the gap Next of Kin Plan is built to close.
All three have free tiers or trials. Test with one real bill and one real contact before you pay for any of them.

Common questions
What is the difference between a digital vault and estate readiness?
A digital vault stores documents. Estate readiness pulls the answers out of those documents so your family can act without reading them. A vault holds the insurance policy. Readiness means the company name, the policy number, and the phone number are already on top, and the right person can see them.
Is Trustworthy worth it?
For households with several professional advisors and a large volume of paperwork, it is built for exactly that and worth a look. For a household that mainly wants the people around them to know what to do, a filing system answers a different question.
Is Prisidio the same as the AARP Digital Vault?
The AARP Digital Vault is built on Prisidio through a partnership between the two companies. AARP members have historically been able to add it to their membership for a lower annual price than the standard plan. Check AARP for current terms.
Can I use more than one of these?
You can, but most families should not. Information split across two systems is worse than information in one, because now your family has to know about both.
Which one is best for organizing an aging parent's information?
Next of Kin Plan, for three reasons: you can photograph a bill instead of typing it in, you can decide exactly what each family member sees, and medications are tracked with individual visibility controls. Those three things matter more in a parent's situation than storage capacity does.
I already work with an attorney and an accountant. Do I still need something like this?
Your professionals each hold their own piece. Your attorney has the will. Your accountant has the returns. Nobody holds the map that connects them, and none of them can tell your daughter which bank holds the mortgage or what your mother takes every morning. That map is what estate readiness is.
You can also bring those professionals in directly. Share with a Professional sends them a read only link to the sections you pick, with no account required on their end, an automatic expiry after seven days, and account numbers excluded.
