Your Unfinished Thoughts Deserve Privacy, Too

August 28, 2026 · By Michel Valenzuela, Founder of Daryl

There is a moment before an idea becomes something you are ready to share.

You have a direction, but you cannot quite explain it. You are considering a change, but you have not decided what it means. You write a sentence, read it back, and realise you believe something slightly different.

That stage matters to me.

Much of my work begins there: between a feeling that something is possible and a clear understanding of what to build, say, or do next.

It is also one of the reasons I’m building Daryl.

I want a place to think with AI where keeping the conversation on your own computer is part of the design.

The draft contains more than the final version

A finished piece of work is selective.

A proposal presents the direction you chose. An email communicates what you decided to say. A business plan describes the assumptions you are prepared to act on.

The thinking behind those things is often much less orderly.

You might explore an idea you later reject. Express frustration you would never put in a message. Question a commitment before deciding to honour it. Consider several possible futures before choosing one.

Those thoughts help you reach the final version. They also reveal things the final version leaves out.

When we use AI to help develop our thinking, that distinction deserves attention. We may be sharing the entire process of arriving at an answer.

Having a thought is different from endorsing it

Exploration needs room for revision.

You should be able to ask whether an idea makes sense without treating the question as a declaration of belief. You should be able to examine an uncomfortable possibility and then dismiss it.

I value that freedom in my own work.

Sometimes I need to make the strongest case for a direction before I can see its weaknesses. Sometimes I need to write the blunt version of a message before I understand what I actually want to communicate.

The rough version serves a purpose. It does not have to represent me forever.

A personal thinking tool should make it possible to work through that process with understandable boundaries around what is shared and what is preserved.

Privacy belongs in ordinary moments

People often discuss privacy in terms of particularly sensitive information: passwords, financial records, confidential documents.

But everyday thinking can be personal, too.

You might be wondering whether to take on another project. Preparing to ask for more responsibility. Trying to understand why a collaboration has become difficult. Exploring a creative direction that feels too fragile to explain yet.

None of those situations needs to be extraordinary to deserve discretion.

The value of a private space is that you can use it before you have decided how much of the thought belongs outside it.

What changes when AI joins the process?

An AI conversation can bring together more context than you would normally put in a single document.

To get useful help, you may explain what happened, why it matters, what you are worried about, and what you hope will happen next.

That context can make the exchange more useful. It also makes the choice of tool more consequential.

I think people should be able to understand the arrangement before bringing their personal thinking into it.

Where is the conversation processed? What is stored? Can you review it? Can you remove it? Does an optional feature send information to another service?

These are practical questions. Clear answers help you decide what to share.

Why I chose local processing for Daryl

For Daryl, I chose to build around local processing for core conversations.

Daryl is a personal AI for Mac, currently in development, intended to help you explore ideas and think through decisions through voice and typing.

Processing those conversations on your computer reduces the need to transmit their contents to a remote AI service.

That matters to me because the experience I want to create invites people to bring thoughts that are still developing. I want the architecture to reflect the personal nature of that work.

Local processing is one part of the design. Storage, permissions, and any optional online capabilities also need clear boundaries. People should understand what happens when they use a feature.

Remembering should be a choice

Continuity can make an assistant more useful.

Context about a project, a preference, or a goal can help a later conversation begin somewhere productive. But useful memory also needs room for correction and removal.

You may change your mind. A project may end. Something relevant last month may no longer belong in the picture.

Daryl’s local memory and continuity system is part of the development roadmap. My intention is to give people control over the context they choose to preserve, including the ability to review and remove it.

Remembering everything is not the objective. Keeping useful context under your control is.

A space before the world sees the work

I have spent much of my life making things.

Across art, business, and software, I keep returning to the same experience: the early version rarely looks like the finished work. Getting somewhere worthwhile requires experimentation, uncertainty, and the willingness to revise.

I want technology to support that stage with care.

An idea can become a product. A difficult question can become a clear decision. A rough paragraph can become the message you were trying to write.

Before any of that happens, you deserve space to work it out.

That is part of the thinking behind Daryl.

Your unfinished thoughts deserve privacy, too.
