Tell your AI once.
Every AI remembers.
Viewert keeps your decisions, rules and preferences in one private place, and gives them to Claude, ChatGPT and any AI you use. Connect once. Never re-explain yourself again.
Free plan · No credit card · Ready in two minutes
An example. You tell Claude that your project now uses Postgres 16 and not MySQL. Claude saves it to your Viewert as a Memory, and it is in force straight away. A week later, in a new ChatGPT chat, you ask which database to use, and ChatGPT answers Postgres 16, because it read your Memory from Viewert.
Say it once
Tell any AI a decision, a rule or a preference, in your own words.
Every AI knows
Claude, ChatGPT and any other AI you connect read the same Memories.
You stay in charge
Private to you. Look through, edit or undo anything an AI writes, any time.
Claude is a trademark of Anthropic and ChatGPT of OpenAI. Viewert is not affiliated with, or endorsed by, either.
Connect Claude or ChatGPT in a minute. Nothing to install.

Everything you use, in one place
Your car, your phone, your barber, the company that keeps the lights on — five areas of daily life around a fire that grows as you add. Each one tap from its help. Private until you share.
Try it — these are examples
Tap a + to light a place. Every area you start makes the fire bigger.

AI is powerful. But it keeps forgetting you.
Every new chat starts from zero — because your knowledge lives everywhere except where AI can reach it.
Every AI conversation, you:
Your knowledge is:
From scattered notes to AI-ready context
Write once. Connect to any AI. Your context loads automatically — every session, every tool.
Write your knowledge
Create Vellums — rich-text docs for anything you keep re-pasting: your coding style, brand voice, research notes, project specs, or study guides.
Bundle into a Libram
Group related Vellums into a Libram — a curated context bundle. Toggle each Vellum's AI switch to control exactly what the AI sees.
Connect to any AI
One MCP URL. Paste it into Claude, Cursor, ChatGPT, Gemini, or Grok — one setup, every tool, every session.
A real, live Vellum — not a mockup. This is what people actually write.
Same question. Completely different answer.
Pick a role and see exactly what changes when AI finally knows who you are.
AI has no idea what you built, who you're selling to, or what you charge. Back to square one.
AI knows your product, ICP, pricing, and brand voice. Sends you a draft you can actually use.
Obsidian helps you think.
Viewert helps AI think with you.
Private by default
Vellums and Librams are yours alone unless you choose to share — your research, architecture decisions, and brand voice stay secure.
Rated when shared
What you publish to the Hall gets real feedback — Poor · Good · Excellent — building your reputation from actual use, not vanity metrics.
We Built Viewert
for Ourselves First
Every AI session started the same way: open Claude, open Cursor, and immediately start copy-pasting the same context. Every. Single. Time.
We were re-explaining our own product to an AI 40 times a day — so we built Viewert. Once we stopped re-explaining ourselves, the quality of every AI session changed completely.
“The competitive advantage wasn't which AI we used. It was the quality of context we gave it.”
We're opening it to everyone who works with AI and knows there's a better way. Join us.
Stop re-explaining
yourself.
Build your knowledge layer once. Every AI you work with loads it automatically — every session, forever.
