One memory across every AI you use — ChatGPT
Zero to memory in one click.
Monday, you told it everything about the Henderson job. Tuesday, it asked “Who’s Henderson?” That ends today.
Add UltraMemory to the Claude you already use. From this chat on, your AI remembers you — your projects, your people, the way you work. Tell it something once and it stays told. And when it doesn’t know, it says so.

For you
You never re-introduce yourself again.
“Every morning I re-explain my whole project. Same explanations, same questions, every single day.”
→ Now your AI opens the chat already knowing the project. You start where you left off — never at zero.
“It made something up — and said it with total confidence. I didn’t catch it until it had already caused a mess.”
→ Now it checks its memory before it answers — and when it doesn’t know, it tells you so.
“I set everything up in Claude on my laptop. My phone had no idea who I was.”
→ Now one memory follows you everywhere — laptop, phone, every AI you connect.
It’s not you. Today’s AI is built to forget. Yours isn’t anymore.
Real pain points from public forums (Hacker News, GitHub, Reddit) — paraphrased, not testimonials. UltraMemory is in early access.
How it works
About a minute to set up. Remembering from your first chat.
If you can add a contact to your phone, you can do this. Nothing to install, nothing to learn.
- 1
Click Add to Claude.
Claude opens with UltraMemory ready to approve. One click, one approve. That’s the whole setup.
- 2
Chat like you always do.
Talk about your projects, your people, your decisions — the way you naturally do. No commands to remember.

Tomorrow, your AI already knows you.
New chat, new day, new device — it picks up right where you left off. And when it isn’t sure, it asks instead of guessing.

Tested in public
The memory that says “I don’t know.”
Most AI memory has one dangerous habit: when it can’t find the answer, it makes one up — and it sounds exactly as confident as when it’s right.
So we tested for the opposite. Ask UltraMemory about a meeting it never saw, and it won’t bluff. On LOCOMO, a public test of long-running conversations, it correctly said “I don’t know” 90.2% of the time it didn’t know — instead of inventing something that sounded right.
how often it correctly admitted it didn’t know, when it didn’t. LOCOMO public benchmark, our own published run.
We publish the whole scorecard, not a highlight reel — what it got right, what it got wrong, and exactly how we ran the test, all in the docs. When a number is ours, we show our work.
For your business
One memory for your company. A private one for each person.
Priya joins your team on Monday. By Tuesday her AI already knows your customers, your pricing rules, and the way you write — because the company memory came with her seat.
Your business runs on what people remember.
Right now, your company’s real knowledge lives in a few heads, a shared drive nobody searches, and a binder behind a truck seat. Codes change. Parts get superseded. Products get discontinued. Policies get rewritten. And when your best person leaves, everything they know walks out the door with them.
Your people already ask AI for help. Without your business in its memory, it guesses — confidently.
UltraMemory keeps your company’s knowledge current every day — not just the day someone wrote it down.
Two Memory Layers. One Grounded Outcome.
What your company knows: products, customers, decisions, how you work. Owners and admins decide what goes in, so company knowledge stays clean — and every member’s AI knows it.
Each person’s own memory: their drafts, their notes, what works for them. Not visible to anyone else — not even the account owner. Locked by the server, not by a setting someone can flip.
Every answer draws on both at once: your company’s truth first, personalized to you.
One system. Two memory layers.
Trusted by Teams. Built for Business. Designed for Enterprise.
Guardrails your company controls. Privacy your people trust.
- +Owners and admins decide what goes into company knowledge — it stays curated, controlled, and audited.
- +Every change is logged: what came in, when, and what it replaced. You answer “who knew what, when” — with dates.
- +Each person’s private memory is theirs alone. Not visible to teammates, not visible to the owner. Locked by the server, not by a setting someone can flip.
Drop in documents.
Upload PDFs, Word files, notes, or spreadsheets — they become living memory, with a log of every upload.
Sync from your own systems.
Your knowledge already lives somewhere on your side? Connect your own systems and a nightly sync keeps UltraMemory current, hands-free.
Connect your tools.
coming soonNotion and Google Drive auto-sync, so the source your team already maintains becomes the memory their AI already knows.
Your facts change. Your memory keeps up.
A part gets replaced. The update lands, and every technician’s AI answers with the new part. The old fact isn’t deleted — it retires with its dates, so “what was true in March” is still answerable.
A product is discontinued. A salesperson asks, and gets “discontinued as of June” — not a confident yes on something you no longer sell.
A policy is rewritten. Upload the new handbook. The old rules retire, the new ones answer, and anything unclear waits for a one-click admin review.
Update a fact once, and every member’s AI knows it from that moment. Old truth retires. Current truth answers. Nothing is ever silently made up.
And your people? They do nothing.
No new app. No training day. No password to forget. Their claude.ai and their Claude app on their phone just know — your team’s knowledge is already in every answer. Zero friction is the feature.
Kick the tires free first.
Start on the Free plan yourself — no credit card, no sales call, no demo to sit through. Watch it remember your week. When you’re sure, start a team: $99/month, 3 seats, and the whole company remembers.
You don’t need to ask — UltraMemory already knows. It recalls, reminds, and surfaces what you didn’t even know you needed.
In the wild
Eight businesses. Same Tuesday. Same fix.
Tap any card for the full story. Every one is the same product doing the same job: your business’s knowledge, in every worker’s AI, current every day.
The HVAC dealer whose techs stopped calling the office
12 techs, 4 counties, code rules that change every year.
The truck rolls with this year’s code, not last year’s.
The HVAC dealer whose techs stopped calling the office
An HVAC dealer runs 12 techs across 4 counties. Each county updates its code requirements on its own schedule, and manufacturers replace parts mid-season.
The current rule lives in the senior tech’s head or a binder behind the truck seat. A tech asks an AI for help and it answers from the old spec — confidently. Wrong part ordered, failed inspection, second trip.
The office drops code updates and part bulletins into UltraMemory. Every tech’s Claude — in the truck, on their phone — answers with the current county rule and the current part. The old spec retires with its dates, so “what did the code say in March?” still has an answer.
The truck rolls with this year’s code, not last year’s.
The sales team that stopped selling a ghost
item #2043 was discontinued in June; the catalog sync told every rep’s AI the same day.
Nobody sells what you no longer make.
The sales team that stopped selling a ghost
A distributor carries about 900 items. Item #2043 gets discontinued in June.
Two weeks later a rep quotes #2043 to a customer — the AI helped write the quote from memory of a product that no longer exists. Now there’s a promised order you can’t fill and an apology call to make.
The catalog sync marks #2043 discontinued. Every rep’s AI answers “discontinued as of June — here’s the replacement.” The quote goes out with the right item the first time.
Nobody sells what you no longer make.
The law office where the new procedure took effect everywhere at once
a 9-person firm rewrote its intake rules; the old version retired the day the new one landed.
The whole office runs on the current version — from the day it changes.
The law office where the new procedure took effect everywhere at once
A 9-person firm rewrites its client-intake and conflicts-check procedure.
The new procedure goes out in an email half the office reads. For months, two versions run at once — and nobody is sure which version a given file followed.
The office manager uploads the new procedure. The old rules retire the same day, every person’s AI answers with the current version, and the change is logged: what changed, when, and what it replaced.
The whole office runs on the current version — from the day it changes.
The agency where every writer sounds like the client
12 clients, each with its own voice, banned words, and approval rules, in every writer’s AI.
Every writer sounds like the client — from day one.
The agency where every writer sounds like the client
A 15-person agency serves 12 clients — each with its own voice, banned words, and approval rules.
Client rules live in old kickoff decks and one account manager’s memory. A new writer drafts in the wrong voice, and the client catches it before anyone inside does.
Each client’s rules live in UltraMemory. Every writer’s AI drafts in that client’s voice, skips the banned words, and flags the approval steps — from their first day on the account.
Every writer sounds like the client — from day one.
The consultant whose clients each get a perfect memory
7 clients, zero re-explaining, nothing re-litigated.
Every client gets treated like the only client.
The consultant whose clients each get a perfect memory
A solo consultant juggles 7 clients, each with its own history, numbers, and personalities.
Every work session starts with ten minutes of re-explaining the client to the AI. Details slip. Last month’s decision gets re-argued from scratch.
Each client’s whole history is in memory. Open a chat, name the client, and the AI is current: the numbers, the people, what was decided and why.
Every client gets treated like the only client.
The support team that answers everything once
the current answer lives in one place; when the product changes, the answer changes once, for everyone.
Answer it once. The whole team answers it forever.
The support team that answers everything once
A 6-person support team fields the same 40 questions — and the right answers change with every product release.
Answers live in an outdated help doc and one lead’s chat history. New hires ask the person next to them. Answering the same question all day is exhausting — and wrong answers still reach customers.
The current answers live in company knowledge. Every agent’s AI gives the current answer; when the product changes, the answer changes once, for everyone. And when the answer isn’t there, the AI says so instead of improvising to a customer.
Answer it once. The whole team answers it forever.
The property manager who remembers every building
30 buildings’ quirks, vendors, and service history, out of one coordinator’s head and into everyone’s AI.
Unit 4B’s history answers the phone with you.
The property manager who remembers every building
A property management company runs 30 buildings — each with its own quirks, vendors, and lease rules.
“Which plumber handles the Elm Street building?” and “when did we last service that boiler?” live in one coordinator’s head. When she’s out, everyone waits.
Building histories, vendor lists, and lease rules sit in company knowledge. Anyone’s AI answers with the right vendor, the service history with dates, and the rule for that exact building.
Unit 4B’s history answers the phone with you.
The billing office that keeps up with the insurers
payer rules change constantly; now they change once, for the whole office, the same day.
The claim goes out right the first time.
The billing office that keeps up with the insurers
A medical billing office works claims for 20 practices, and every insurer has its own rules — rules that change all the time.
Payer quirks live on sticky notes and in one senior biller’s memory. A rule changes, claims go out the old way, and denials pile up to be reworked weeks later.
The office keeps its payer rules in company knowledge. Every biller’s AI answers with the current rule for that insurer — and when a rule changes, it changes for the whole office the same day. The old rule retires with dates, so last quarter’s claims are still explainable.
The claim goes out right the first time.

How we compare
Plenty of tools can store. Only one knows when to stay quiet.
Lots of tools save what you tell them. The differences show up later — when facts change, when the answer isn’t there, and when your whole team needs the same recall.

Questions
Straight answers.
Do I need to be technical to use this?
No. If you can add a contact to your phone, you can set this up. One button, one approval, done. There’s nothing to install and nothing to maintain.
Is it really free? What’s the catch?
Really free: no credit card, no trial clock, no surprise bill. The Free plan has every feature and enough monthly memory to feel the difference. When you want more room — or seats for your team — the paid plans are right there. That’s the whole model.
Is my data private?
Yes. Your memories belong to you. Nothing you store is used to train AI models, nothing is sold, and nothing is shared outside your account. You see everything it remembers — and delete any of it — anytime.
Is my team’s shared knowledge private?
Yes — private twice over. Your team’s shared memory is visible only to your team’s AIs, and only owners and admins decide what goes into it. Separately, every member has a personal memory that nobody else can read — not teammates, not the account owner.
Do my employees need to learn a new tool?
No. They keep using the claude.ai and Claude apps they already have. Company knowledge is already in every answer — nothing new to install, learn, or log into.
Can my business try it before paying?
Yes — that’s the intended path. Start on Free yourself: no card, no sales call. Watch it remember your week. Start a team when you’re sure.
What happens when our information changes?
Updates replace, they don’t pile up. When new information arrives on the same topic — from an upload, a sync, or an admin edit — the old version retires automatically, and every member’s AI answers with the current truth from that moment. History is kept with dates; nothing stale is served as current.
Can we remove something we added?
Yes. Admins retire any entry from the company knowledge console in one click, and a staleness review shows what hasn’t been used lately, so the memory stays clean.
What happens if I go over my plan’s limit?
Nothing dramatic. We warn you as you get close (at 80% and 90%), and at 100% new activity simply pauses until your month resets — or you add headroom in one click. Nothing is ever deleted, and everything already remembered stays safe.
Will it slow my AI down?
You won’t notice it. Remembering happens in a blink — and because your AI reuses what it already knows instead of working it out again, chats often get faster, not slower.
How is this different from other memory tools?
Most tools store what you tell them. UltraMemory also admits when it doesn’t know, updates itself when your facts change, and gives a team one shared memory plus a private one per person. See the honest side-by-side — names, sources, and where others beat us — in the detailed comparison.
Am I stuck with you?
No. Your memories are yours: view them, export them, or delete them anytime, and cancel in one click. We earn next month instead of locking you in.
What does “early access” mean?
The product is live and real people use it every day — but we’re early, and we say so. You get direct access to the people building it, and we publish our test results instead of polishing them.
Your AI remembers you now.
One click, and it never asks “Who’s Henderson?” again. It knows you, it knows your business, and it tells you the truth about what it knows.
Developers — the same memory drops into Claude Code, Cursor, or anything you build. One link and a key; the docs walk you through it.
