Chat-first system doctor

Stop googling error codes.
Just ask your computer.

Type what's bothering you — "my PC is slow", "this upload keeps failing" — and Otto checks your machine, finds the actual cause, explains it in plain English, and fixes it with one click. No settings, no jargon, no expertise required.

Otto — new chat Free trial · 5 days left
My laptop has been really slow lately. What's wrong with it?
Give me a moment — checking your disk, memory, startup items and background services…

Found it. Your C: drive is 92% full and Windows Update has failed 14 times in 24h because it can't write staging files. A 18 GB temp folder is making everything worse.
Ready to fix: Clear the temp folder and let Windows Update finish. Fix it

What Otto does

A conversation, not a control panel. It checks what a specialist would check — then talks to you like a person.

1

Ask in plain language

"Why is my computer slow?" "Why won't this file upload?" No settings to configure, nothing to learn. If you can describe the problem, Otto can investigate it.

2

It actually checks your machine

Unlike a chatbot, Otto runs real diagnostics: disk, memory, startup items, services, background processes. Every conclusion comes with the evidence it found.

3

Explains, then fixes

You get the cause in plain English, plus one-click fixes for the safe stuff. Anything risky shows you exactly what will happen before you approve it.

↩

Every action is reversible

Otto keeps a complete journal of everything it changes. If a fix doesn't feel right, undo it with one click — no orphaned settings, no "what did it just do?"

✓

Nothing happens without your approval

Otto never touches your system on its own. Every fix shows exactly what will change and waits for your explicit confirmation. You are always in control.

Inside the app

A chat that can actually touch the machine — safely, transparently, on your terms.

Ask, don't configure

Every answer is a three-part card: the situation, the exact checks it ran with the evidence, and the fixes — each with a one-click button. Nothing hidden, nothing vague.

Finds what you'd never find

Multiple antivirus tools quietly eating your RAM. The one bad file breaking every Google Drive upload. The startup app that's been halving your boot speed for a year. Otto correlates the symptoms and names the culprit — with numbers.

Otto — Knowledge Trial · 5d Pick a checkup — or just ask in chat Playbooks are guided checkups for common problems. % Free up disk find what's eating space ▲ Startup audit what's slowing boot ⇅ Upload failures why transfers break M Memory hogs find RAM eaters ✓ Health check full once-over ~ Network weird wifi / dns issues ✓ Upload failures — yesterday Found 1 file with an unsupported character in the name blocking the whole Google Drive sync.

Guided checkups when you don't have a question

Not sure what to ask? Playbooks are one-click investigations for the usual suspects: disk space, startup, memory, uploads, network. Results are saved so you can compare over time.

What early users say

From people who were about to buy a new computer, to software engineers who thought they didn't need help.

★★★★★

"One of the best tools I've ever used. I was about to buy a new laptop — then Otto cleaned up my storage and now it keeps freeing memory for me on demand. Saved me $1,200."

— Verified beta user, was shopping for a new PC
★★★★★

"Zero setup. You just ask. It's like having a computer expert sitting next to you 24/7."

— Verified beta user
★★★★★

"I'm a software engineer, so I assumed it wasn't for me. Then my Google Drive uploads kept failing — tried everything. Otto found it in one check: one file with an unsupported format was blocking the sync."

— Verified beta user, software engineer
★★★★★

"I thought my computer was fine. Otto found several antivirus programs quietly eating my memory in the background. It's the only PC tool I can actually use — no settings, just questions. And unlike ChatGPT, it can actually check my machine and do the fix for me."

— Verified beta user, self-described computer novice

Common questions

How is this different from just asking ChatGPT?
A chatbot can only guess from what you type. Otto runs real diagnostics on your actual machine — disk, memory, services, event logs — and bases its answer on evidence it collected. Then it can perform the fix for you, with your approval. A chatbot can't do any of that.
Is it safe to let it "fix" things?
Yes, by design. Safe actions (clearing temp files, disabling a redundant startup app) are one-click and reversible. Anything risky shows you exactly what will change before you approve it — and v1 ships read-only first, so it can only tell you, never touch. Write actions arrive in v2 behind explicit approval.
Where does my data go?
Your diagnostics run on your machine. The data goes to the AI that answers your question — and nowhere else. We don't store it, sell it, or train on it. What we keep server-side is just what billing needs: your license status and usage counts.
Do I need my own AI key or a ChatGPT account?
No. Every plan includes AI credits — free tokens during your trial (enough for several complete fixes), a generous monthly allowance with Pro. Nothing to paste, no OpenAI account to set up.
Do I need to configure anything?
Nothing. Download, ask your first question — the AI is already included and already set up. No settings to learn; the whole product is a conversation.
What exactly do I get free? What's the catch?
Seven days, every feature, on one computer — including real fixes, not a demo. We include free AI credits worth several complete diagnose-and-fix cycles, enough to actually solve a few real problems with your machine. When the credits or the week run out, Pro is $4.99/mo (first month $2.99) — no ads, no data sales.
How does the first-month $2.99 work?
When you click "Subscribe" during or after the trial, Stripe Checkout automatically applies a one-time $2.00 discount, so the first invoice is $2.99 instead of $4.99. From the second month on, the standard $4.99/month kicks in. You can cancel anytime from the Stripe customer portal before the next charge.
What happens when I cancel?
Your subscription stays active until the end of the current billing period. After that, the app reverts to the trial state — but because each machine only gets one trial, you'll need to subscribe again to run more diagnoses. Your history stays on your machine regardless.
Is the installer signed?
Yes. We sign with a code-signing certificate so Windows SmartScreen doesn't flag the installer as "unknown publisher".
