Sure! What does your company do? Who's the target customer? What's the pricing model — subscription, per-seat, usage-based? Do you have any existing messaging I should match?

AI has no idea what you built, who you're selling to, or what you charge. Back to square one.

Libram loaded: Company Context
Here's a cold email for your Series A SaaS targeting ops managers at 50–500 person companies, anchored on the $299/seat/month price point and leading with the 40% reduction in manual reporting your case studies show. I've matched the direct, no-fluff tone from your brand voice guide…

AI knows your product, ICP, pricing, and brand voice. Sends you a draft you can actually use.

Sound familiar?

Every AI conversation starts from zero.

You've been re-explaining your project, re-pasting your notes, and re-typing your preferences into every new AI chat. For months. That ends here.

Re-paste the same context

Every chat starts blank. You copy your codebase, your notes, your preferences — again and again across ChatGPT, Claude, Cursor, and Gemini.

Generic AI, generic results

Without your context, AI gives you generic answers. You're prompting in the dark instead of directing a tool that actually understands you.

Knowledge that evaporates

Your best insights are in a Notes app you forgot to check, a doc you can't find, and a conversation thread you'll never scroll back to.

Three steps, two minutes

From scattered notes to AI-ready memory

Write once. Connect to any AI. Your context loads automatically — every session, every tool.

1

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. No noise.

Connect to any AI

Connect via OAuth MCP for Claude & Cursor, or use an API key for any MCP client. Paste your context URL into ChatGPT, Gemini, or Grok. One setup — every tool, every session.

OAuth MCPAPI keyURL paste
Universal compatibility

One context infrastructure. Every AI.

Build your knowledge graph once. Deliver it to any AI tool — however they accept context.

Claude Desktop

OAuth MCP (recommended)

Add the MCP URL and sign in once. Claude auto-discovers your Librams and loads any on request — no API key needed.

Cursor & Windsurf

OAuth MCP

Add the MCP URL to your project config. Sign in once via browser — your Librams load in every coding session.

ChatGPT

Context URL paste

Paste your Libram's public context URL. ChatGPT reads your knowledge instantly — no account needed for public Librams.

Gemini

URL or system prompt

Paste your context URL directly or inject Libram markdown as the system prompt in AI Studio.

Grok

URL or direct paste

Grok's large context window handles full Librams. Paste URL or markdown — your knowledge loads in one message.

Llama / Local Models

API endpoint + curl

Fetch your Libram as markdown with curl and inject as system prompt. Fully private — your notes stay on your machine.

Real Vellums. Real context.

These are the kinds of knowledge documents people build in Viewert and load into their AI tools every day.

What AI conversations actually look like

Without Viewert

"Write me a marketing email."

AI knows nothing about your brand, audience, or tone → generic output

With Viewert Libram loaded

"Using my Brand Voice Libram — write a launch email for [feature] targeting [audience]."

AI knows your tone, audience, vocabulary, and past copy — produces on-brand output immediately
Anyone who uses AI, daily

Built for people who think in AI.

Developers

Load your codebase conventions, architecture decisions, and API docs into Cursor or Claude. AI codes in your style from the first line.

Researchers

Bundle annotated paper summaries into a Libram. ChatGPT or Gemini synthesises your entire literature review in minutes.

Writers & Marketers

Store brand voice, audience personas, and tone guidelines. Every AI draft comes out on-brand without repeated instructions.

Students

Build subject Librams for exam prep. Load them into any AI tutor — no more re-explaining your course context.

Product Managers

Keep user stories, acceptance criteria, and specs in a Libram. AI coding sessions start with full product context automatically.

Anyone re-pasting notes

If you've ever typed "here's some context about me/my project" into an AI chat — Viewert automates that forever.

Live from Hall

See what people are talking about

The Hall is where ideas spark, conversations flow, and the community comes alive.

I used to copy-paste my codebase conventions into every Cursor session. Now I load a Libram and Cursor just knows. It's like it finally has memory.

— Backend engineer, Series B startup

Finally a notes app built for AI-first workflows. The Libram format is exactly what I needed to stop re-explaining my research to Claude every session.

— PhD researcher, Stanford

My AI copywriting went from "pretty good" to indistinguishable from my own work. Viewert loads my brand voice, and the AI speaks in my voice immediately.
