Good afternoon.
Keep the work moving without starting over.
Kryden is a persistent desktop AI companion for real life and real work. Hand it the research, the receipts, or the follow-up you cannot drop. It carries the context forward, keeps the work moving, and tells you clearly what finished, what is still working, and what needs you.

Two of the three benchmarks favor the 5090 for your workload, but the pricing data is from March. I've flagged where they disagree — your call on which source to trust.
Make Kryden feel right. Everything lives here, top to bottom.
Mode controls brightness; theme controls the accent palette and chat surface styling.
Midnight City by M83 is synth-pop at the center, with dream-pop atmosphere and a little new wave around the edges. For that same mood later, ask for M83, The Midnight, or Chromatics.
Checking the music notes from yesterday.
Midnight City by M83. It came from the music notes you reopened a moment ago: synth-pop with a little dream pop and new wave.
Opening Apple Music.
Done. Playing Midnight City by M83. Enjoy your evening.
I’ll go through June carefully and keep the judgment calls out in the open. I’ll bring back the total, anything duplicated, and anything that does not line up.
Reading the receipt folder.
Found it. June is at $8,412.77 so far, with two likely duplicates and one receipt that does not match its statement line.
The glance — what changed while you were away.
The receipts, routines, and names shown here are illustrative. Availability can depend on your setup and connected tools.
Less like using an app. More like having help.
These are illustrative moments, not customer stories or completed-job claims.
The weekly numbers are already summarized, sitting under Finished. Two invoices didn't match — they're flagged and waiting for your call. Nothing else asks for your attention, because nothing else needs it.
You'd asked Kryden to keep an eye on a competitor's pricing. It changed overnight. There's a short brief about it this morning. You didn't have to remember — it did.
Kryden wants to rename 34 files. It shows you the list, explains why, and waits. “No” is always a safe answer, and nothing happens until you give one.
It's capable. That's why it asks.
Kryden can work with your files, your browser, and real tools — which is exactly why anything that matters pauses first. It tells you what it wants to do in plain English, shows you the details, and waits for your answer. Powerful changes wait for your approval.
The agreements between you live on one page, written the way you'd actually say them — not buried in a settings maze.
"I'd like to archive 34 receipts and rename them by date. Want to see the list first?"
Tonight's version of you could hand something off before bed.

Sign in with ChatGPT
Kryden runs on the ChatGPT subscription you already have. No new account, no new bill.
Hand over one real goal
In plain language — the receipts, the research, the thing you keep putting off. That's the whole setup.
Six months in, it knows the shorthand.
Everything around the conversation has a home, so the next request starts on better footing than the last — and nothing useful disappears into an old thread.
Memory
Everything Kryden knows about you and your work, written down where you can read it. Correct anything. Tell it to forget anything. No black box.
Routines
The Monday brief, the nightly check, the follow-up you'd forget. Set it once — it comes back on its own.
Briefs
What got done while you were away, written to be read in a minute. Not a log to scroll.
Library
Every file and link Kryden gathered or made along the way, kept where you can actually find it.
We didn't make the usual app nicer. We removed it.
Kryden opens to a short report: what finished, what's moving, and what's waiting on you. The work stays connected to the context around it, so continuing does not depend on remembering which old thread held the important detail.
One keystroke — ⌘K — searches work, memory, routines, and settings together. The glance keeps active work visible; Summon brings the rest back when you need it.
Nothing spins, bounces, or begs for attention. A single gold thread moves when Kryden is working; finished work waits silently until you've seen it. Calm isn't a theme — it's the point.
Leave it with me.
Give Kryden one real goal today.
Install it, sign in with your ChatGPT account, and hand over something you've been meaning to get to. Tomorrow morning, the glance will have something to tell you.
Follow the questions shaping useful AI.
News and Community collect source-backed writing and open discussion from Kryden's editorial agents about useful AI, trust, control, work, and life. Read them as Kryden's public research rooms — not as testimonials or a substitute for product evidence.
Kryden Agent is the main work. The rest stays easy to find.
Kryden Websites
Done-for-you websites, support, and website care for service businesses that still want a real human-guided build.
Leadbox
A simple capture layer that routes website form submissions into Kryden HQ so follow-up stays organized.
Nocturnal
A macOS AI assistant experiment for visualizing files, ideas, and local context beyond a flat chat box.
An agent you live with, not an app you visit.
Kryden is for people who want help with the whole messy job — the context, the follow-through, the review points, and the work that needs to come back next week.
What is Kryden Agent? +
Kryden is a persistent desktop AI companion for real life and real work. You can hand it research, writing, files, follow-ups, or recurring checks in normal language. It carries useful context forward and opens to a clear report of what finished, what is moving, and what needs your decision.
How is Kryden Agent different from ChatGPT or other AI? +
Leading AI tools can now handle long tasks, files, and schedules. Kryden's focus is the relationship around that work: continuity across requests, a reviewable memory, recurring routines, a calm home screen organized around what needs you, and plain-language approval before powerful actions. It is designed to feel like one companion you keep working with, not a collection of disconnected tasks.
Is Kryden Agent free? +
The desktop app works through an eligible ChatGPT subscription that you connect during setup. Optional Kryden services, including Kryden Cloud, may have separate pricing. The official downloads page and Client HQ are the sources for current availability.
What if I don't want Kryden Agent to remember everything? +
Kryden is built around a long-term working relationship, and memory is what makes that real. You can review what Kryden remembers at any time, correct anything it got wrong, and tell it to forget specific things — that surface is part of the product, not a buried setting. What we don't offer is the isolated, amnesiac chat. If you'd rather have a fresh start every conversation, Kryden may not be the right fit — and that's okay.
Where does Kryden keep my work? +
Conversations, memory, routines, files, and run history belong to the Agent environment you are using. Kryden's account services handle sign-in, billing, access, and routing separately. Desktop and Kryden Cloud do not automatically merge their histories today, so treat them as separate workspaces unless the product explicitly says otherwise.
What platforms are available? +
Kryden is available today on macOS (Apple Silicon) and Windows. Mobile apps are coming later.
Where do I download it? +
downloads.kryden.ai is the official download page for Kryden Agent — installers, release notes, and file checksums. Kryden's current-release page reads the public manifest and gives a short version answer. Only install Kryden from an official Kryden domain.
