"Who's who in my zoo?"
Your clients told you
in confidence.
An AI memory that actually keeps it that way.
Coaches, clergy, solo financial advisors — if your work comes with a confidentiality obligation, most AI tools aren't an option. WhosWhoZoo runs entirely in your own Cloudflare account. Your notes never reach us — there is no WhosWhoZoo server for them to sit on.
The name comes from an Australianism — "who's who in the zoo" means who matters, who does what, all the characters in your world. The phrase is the best description of what this is.

What it is
▸
WhosWhoZoo remembers your world — the people who matter to you (faces included — attach photos to anyone's record), your private journal, quick fragments you'd otherwise lose (links, contacts, things to look up), and open loops you're tracking. Tell it something, ask questions later. Every conversation loads your entire active memory, so Claude always has the context, history, and details you've noted — and your archive is one toggle away when you need it.
Think of it as a smarter notebook that talks back — and that no company keeps a copy of. Voice and text. Mobile-first.
Your notes live as plain text files in your own Cloudflare account — not on any company server. You own them completely. No subscription — you pay Anthropic and OpenAI directly for usage (a few dollars a month to start, growing with your memory).

When you'd use it
▸
Coach with a back-to-back schedule? "What did we work on last session with Sarah?" — answered before she walks in, stored in your own account instead of a vendor's database.
Pastoral counseling notes? They belong in a confessional, not a corporate server — and structurally, WhosWhoZoo doesn't have one to put them on.
Solo financial advisor or RIA? Client budgets, family situations, risk tolerance — in a Cloudflare account you own, under your own credentials, not a vendor's shared database. Your books and records stay somewhere you can actually produce them from, and there's no vendor-review queue standing between you and getting started.
Starting a new job? Remember every name, role, and quirk from your first 90 days of intros.
1:1 in ten minutes? "What did we talk about last time with Maria?" — answered before you sit down.
Family reunion coming up? Pull up your cousin's kids' names before you walk in the door.
Good with names, bad with faces? Send a photo in chat and ask Claude to save it to someone's record. Next time you look them up, you don't just remember who they are — you remember what they look like.
Meeting someone twice in two years? Recall what they care about before the call.
Keeping a private journal? Save reflections, get them back when you need to remember how something felt — written to an account only you hold the key to.
Tired of losing links and contacts? Drop a fragment — "that article on negotiation tactics" or "Sara's direct line at the vendor" — and ask for it later in plain English. Better than bookmarks, because you can ask what you meant instead of guessing what you titled it.
Why professionals choose it
▸
🔒 No server to breach. There is no WhosWhoZoo database. Client notes live in your own Cloudflare account — nothing to subpoena at our end, nothing to leak if we shut down, nothing for a vendor breach to expose.
🎙️ Intentional input only. No passive recording, no always-on mic. You choose exactly what gets saved — a professional requirement, not just a preference.
📄 Plain files you own forever. Notes export as plain markdown. If this project ever shuts down, your records don't disappear with it. No lock-in, no hostage data.

What makes it different
▸
🧠 Curated, not captured. You build your memory deliberately — adding people, correcting what you got wrong, archiving what fades. Unlike passive recorders that dump everything into a haystack, yours reflects your actual understanding of your world. The more you tend it, the more accurate it gets.
🔎 Every answer shows its work. Tap View Sources under any response to see which of your notes it cites — each one checked against your actual records, and anything cited but missing called out. Spot something wrong? You're one tap from editing the record itself. Almost no AI memory tool lets you audit an answer back to its source — and none of the ones in our comparison do.
👁️ Sees everything, every time. Every question loads your entire active memory before Claude answers — the whole file, not a search result. No vector-search guessing at which notes might matter, and archived material is one toggle away when you want it. It gets the full picture every chat: what you wrote is what Claude receives, every single turn.
🔐 Technically yours — not just promised. Your memory lives in your own Cloudflare account. We don't have a database. There's nothing to breach at our end, nothing to sell, nothing to lose if this project shuts down. Plain markdown files — and your photos — in your own cloud, forever.
🚫 No always-on mic. Hardware memory devices record everything — your conversations, other people's conversations, things you'd never want saved. WhosWhoZoo requires intentional input. That's not a limitation. That's a privacy and legal boundary most passive tools quietly ignore.
Stays manageable as it grows
▸
Active records are always available. Older ones archive automatically. Deep history stays searchable forever without cluttering your day-to-day. The app handles the tiers — you just talk to it.
Privacy & cost
▸
⚠️ Most AI tools store your notes on shared servers. Coaches, clergy, and advisors often can't use them for that reason alone. WhosWhoZoo has no server. Your files sit in your own Cloudflare account — structurally impossible for us to access, even if we wanted to.
💰 Most memory apps charge a subscription and keep your data on their servers. This is $39 once, then you pay Anthropic and OpenAI directly for what you actually use — a few dollars a month starting out, more as your memory grows. There's no WhosWhoZoo server holding your notes, so there's no subscription propping one up.
🛡️ Your notes are not used to train AI. Anthropic's API terms exclude API inputs and outputs from model training by default — distinct from the consumer Claude.ai service. Your memory is processed to answer your question, then forgotten. Not stored long-term, not used to improve any model.
🔒 We hold no copy of your notes, and no key to them. There is no WhosWhoZoo memory database and no back-end your files pass through — they sit in your own Cloudflare account, under credentials we don't have. This isn't "we promise not to look"; there is nothing on our side to look at. The one moment we handle anything of yours is during install, when the setup relay forwards your keys to your own account without storing them — spelled out in full on the privacy page.
📷 Your photos live in your storage, not on ours. Attach a photo in chat and it goes to Claude once — that's how it knows what it's looking at and offers to file it. Save it, and that's the last trip it ever takes: from then on the assistant only sees a filename pointing at your own Cloudflare storage. Export your memory and the photos come with it — faces, not just notes.
🔑 Your API keys pass through once, then never again. During setup they travel through whoszoo.app on their way into your Cloudflare account — that's how the wizard can install them for you. We don't log them and don't store them; they exist in memory for the one request it takes to forward them, then they're gone. Once your Worker is deployed, whoszoo.app is completely out of the loop — your app talks to Anthropic and OpenAI directly, every time, forever.
💳 No subscription — fill a bucket. Prepay Anthropic and OpenAI directly and spend only what you use. Early on, with a small memory, that's a few dollars a month. It climbs as your memory does — every question re-sends everything you've ever written — so a heavily-used install with years of notes can land at $15–25/month. Type
/costs any time to see your running total, and set a daily ceiling so it can never surprise you. ElevenLabs voices are optional, same pay-as-you-go deal.📡 No trackers, no phone-home. This landing page loads no tracking scripts and sets no cookies, and the app never calls home — once it's installed you could block whoszoo.app at your firewall and never notice. Your notes, your chats, your usage: I see none of it, ever. For this website I do see aggregate visit counts — which pages, how many, roughly where from — with nothing that identifies a person. The one thing I keep per install is a single line: your purchase email, licence key, and a hashed account ID, so I can spot a licence being shared. That's the whole list, and it's itemised on the privacy page.
📱 Built mobile-first. Voice in, voice out. Biometric unlock. Designed for one-thumb use on a phone.
🌐 English, Spanish, French, and Hindi UI. Switch languages in Settings. All labels, buttons, and menus translate — Claude already responds in whatever language you write in.

★★★★★
“brilliant idea. I have used [WhosWhoZoo] to record reflections of trips and reviews of cruise ships. Works fantastic in recalling all the small details that I have forgotten. Easy to use and install. Definite must use.”

Get it
$39 one-time · works in any browser, any device · no subscription
You'll get a license key by email — it unlocks the setup wizard. Nothing to download. The $39 buys the setup, not the software: the app is MIT licensed and on GitHub if you'd rather deploy it by hand. That $39 is everything you ever pay me. After setup, the only ongoing cost is what you pay Anthropic and OpenAI directly for what you use — a couple of dollars a month for most people, and nothing at all in a month you don't use it. You set a hard spending cap in the app, and none of it comes to me.
14-day refund guarantee — if setup doesn't work out and I can't help you fix it, email [email protected] for a full refund.

How setup works — 3 steps, ~20 min total
▸
1
Get the prerequisites. Create accounts on Cloudflare (free), Anthropic (~$5 prepaid), and OpenAI (~$5 prepaid). Grab your API keys from each — this is most of the 20 minutes.
2
Run the setup wizard. Nothing to download or install — go to whoszoo.app/setup in any browser, paste your license key, then step through your Cloudflare token and API keys. Each one tests live before you can continue. It deploys a private Worker + database directly into your own Cloudflare account. ~2–3 minutes.
3
Open the app. The wizard shows your App URL and a one-time Access Key on the result screen. Save both, pick a passphrase, and you're in. Start adding people.
