Buy Once, Keep Using It: Why Daryl Has No Mandatory Subscription

August 31, 2026 · By Michel Valenzuela, Founder of Daryl

When you buy a tool and it continues to serve you well, you should be able to keep using it.

That is the principle behind Daryl’s pricing.

Daryl is a personal AI for Mac, currently in development, designed to process its core conversations on your own computer. For that experience, I’ve chosen a one-time purchase with an included period of feature updates and an optional renewal afterward.

You can keep using your eligible licensed version without paying a mandatory monthly subscription.

I want that arrangement to be understandable from the beginning.

A familiar approach to software

For years, buying software meant purchasing a version you could use while deciding whether a later upgrade was worth the price.

That approach still makes sense to me.

A useful application can become part of your routine. You learn its interface, develop habits around it, and rely on it for particular tasks. If the version you purchased continues to meet your needs, an upgrade should be a choice you make for a reason.

That is the relationship I want people to have with Daryl.

Future improvements should earn your interest through their usefulness.

What local AI makes possible

Daryl’s core processing is designed to happen on your Mac.

Your computer supplies the resources used to generate those local responses. That gives me room to build a business model around the application itself: its interface, specialised development, integration, testing, and improvements.

There is substantial work involved in making local intelligence useful.

Models need to work within supported hardware. Voice interaction needs careful engineering. Installation, permissions, error handling, and updates all affect whether someone can comfortably use the product.

The purchase supports that work.

Local processing and pricing are separate choices. A local application can charge a subscription, and a cloud service can offer free access. For Daryl, I’ve chosen a model that lets people retain use of the version they purchased.

How Daryl’s pricing will work

The planned launch pricing is:

If you choose not to renew, you can continue using your last eligible licensed version.

The annual renewal is an option for receiving further improvements. It is not a condition for retaining access to that version.

What you are choosing after the first year

Suppose you buy Daryl, use it regularly, and find that it does what you need.

After your included update period ends, new features become available. You can assess them against your own work.

Perhaps a new capability would save you time or make the experience more useful. You may decide the renewal is worthwhile.

Perhaps your existing version already meets your needs. You may decide to keep using it.

Both are reasonable decisions.

The pricing should give you room to make that assessment without a monthly payment being required to continue using the software you already licensed.

What “keep using it” means

It is important to be precise about the promise.

Continued use of your eligible licensed version does not mean every future release is included forever. It also does not mean a version can remain compatible with every future change to macOS or hardware.

Software operates within a changing environment. Compatibility work and further development remain real responsibilities.

The commitment is that choosing not to purchase additional feature updates will not, by itself, revoke your licence to use the version you are entitled to keep.

That is the distinction I want people to understand when considering Daryl.

Improvements still need support

I want Daryl to improve over time.

More comfortable voices, better usability, stronger support for decisions, and carefully developed new capabilities all require continued effort.

An optional update renewal provides a way for people who value those improvements to support and receive them.

It also gives me a clear responsibility as the founder: make the improvements useful enough that people want them.

For me, that is a healthy basis for an ongoing relationship between a product and the people using it.

Personal software should give you room to choose

A personal assistant is something you may bring into your everyday thinking.

You might use it to examine a decision, explore an idea, or work through competing priorities. Over time, the application can become familiar in ways that matter beyond a feature list.

I want the purchase arrangement to respect that relationship.

You should understand what you are paying for, how long updates are included, and what happens if you decide to stop purchasing them.

Daryl’s approach is deliberately straightforward: buy the application, receive the included updates, and choose whether future improvements are worth renewing for.

Why I chose this for Daryl

I’m building Daryl around personal control.

Local processing gives people a way to use core AI conversations on their own computer. The purchase model gives them a way to keep using their eligible version without a mandatory recurring fee.

Those choices reflect how I want the product to fit into someone’s life.

A useful tool should earn its place through what it helps you do. A future upgrade should earn its purchase through what it improves.

Daryl is coming soon to Mac.
