Everything You Need to Build Your AI Knowledge Base
Upload your documents. Clip articles and AI outputs. Organize your knowledge. Share it with any AI tool in one click. No technical setup. No learning curve.
Upload your documents. Clip articles and AI outputs. Organize your knowledge. Share it with any AI tool in one click. No technical setup. No learning curve.
AI Context Keeper works on a simple loop that makes every AI conversation better than the last.
Save documents, clip web articles, capture AI outputs worth keeping.
Keep everything in folders and workspaces that make sense to you.
Give any AI tool instant access to your knowledge with a simple link.
Save valuable AI outputs back. Knowledge base gets richer. Repeat.
Most AI tools treat every conversation as a one-time event. AI Context Keeper turns them into a compounding investment.
You've got knowledge locked in Word docs, PDFs, spreadsheets, presentations, and web pages. AI tools don't handle most of these well — they choke on formatting, miss table structures, and waste space on invisible junk.
AI Context Keeper converts everything automatically into a clean format that AI models understand perfectly. Your content takes up about 70% less space, which means you can share 3x more knowledge in every AI conversation. You don't need to do anything special. Upload your files the way they are. We handle the rest.

~70% smaller · 3x more context per conversation
Every file and every folder in your knowledge base gets a shareable link. When you start an AI conversation — in Claude, ChatGPT, Gemini, Perplexity, Grok, or anything else — paste the link. Your AI instantly has access to that knowledge.
No re-uploading. No copy-pasting documents. No choosing which AI tool gets your best context. One link. Every tool. Done.
Share a single file when you need specific context
Share an entire folder for comprehensive knowledge about a topic, client, or project
Works from anywhere — cloud-based links work on laptop, phone, and tablet
// Start any AI conversation like this:
Context: https://app.aicontextkeeper.com/share/abc123
(Your full knowledge base, instantly loaded)
"Write a proposal for Acme Corp based on our previous work together."
The same shareable links that work with Claude and ChatGPT work identically with LM Studio, GPT4All, Ollama, or any local inference tool.
Use local models for everyday tasks. Save premium tokens for complex work. Your knowledge base stays consistent across every tier — from a free local Llama model to Claude Opus.
A Word doc takes ~68K tokens. That same content in ACK markdown? ~22K tokens. That's the difference between fitting in a local context window and being completely unusable.
ACK doesn't just save space with frontier models — it makes local AI viable for knowledge-intensive work.
// Works across your entire AI stack:
Build whatever structure makes sense to you. Create workspaces for different areas of your work. Add folders and subfolders. Search across everything. This isn't a dumping ground — it's a knowledge library designed to grow with you.
Most users start with a few folders and naturally build out their structure as their knowledge base grows.
Workspace examples:
When we convert your files, we don't just grab the raw text. We preserve the structure so both you and AI can work with it easily.
Your knowledge base is yours. Period.
The Chrome extension is how your knowledge base grows without extra effort. It works right where you already spend your time — in AI conversations and on the web.
You know those moments when AI nails it? A perfect summary, a framework you'll want again, an analysis that connects ideas? Instead of letting it vanish into chat history, click "Save to ACK." Choose a folder. Done.
This is the feature that turns AI from a disposable tool into a compounding one.
Reading an article with useful data? Found a competitor's positioning page? Highlight text, right-click, save. Your knowledge base grows while you browse.
Need to share context mid-conversation? Open the extension sidebar, browse your files, copy a share link. Never leave the page you're on.
Works with Claude, ChatGPT, Gemini, Perplexity, and Grok.

Writing a Proposal
Before
Open AI. It remembers a few basics about you, but nothing about this client or this deal. Upload the RFP, paste in your product specs, explain the relationship history. Fifteen minutes of setup before you even start writing.
After
Paste your company knowledge link and your client workspace link. Ask for a proposal. AI already knows your product, your voice, your client's business, and the style of proposals that have worked before. First draft is 80% there.
Doing Research
Before
Read 10 articles across different tabs. Try to remember the key points. Open AI and summarize from memory. Miss connections between sources.
After
Clip articles to your knowledge base as you read them. Share the research folder with AI. Ask it to synthesize across all sources, find contradictions, identify gaps.
Starting a New Project
Before
New project, new AI conversation. Sure, Claude remembers your name — but it doesn't know this project's context. You spend 20 minutes uploading docs and explaining the specifics.
After
Paste your project workspace link. AI instantly has your full project context. You skip straight to the real work.
Picking Up Where You Left Off
Before
You had a great AI session last Tuesday that produced exactly the framework you need today. But which chat was it in? You scroll through dozens of conversations. Can't find it. Re-do the work from scratch.
After
You saved that framework to your knowledge base last Tuesday. Today you find it in 5 seconds, share it with a new AI conversation, and build on it immediately.
Every AI tool has a limit on how much it can read at once. When you upload a Word doc or PDF directly, a huge portion is invisible formatting overhead. AI Context Keeper strips all of that automatically.
| What you upload | What AI reads | With AI Context Keeper |
|---|---|---|
| Word doc (.docx) | ~68,000 tokens of bloat + content | ~22,000 tokens of pure content — room for 2 more docs |
| ~71,000 tokens — even worse | ~22,000 tokens — 3x more efficient |
Cloud models offer 200K tokens — room for waste. A local model on your MacBook? Maybe 8K–16K. At that scale, format is everything.
| Format | Tokens | Fits in local context? |
|---|---|---|
| Raw PDF | ~71,000 | No — Won't fit at all |
| Word doc | ~68,000 | No — Consumes entire window |
| ACK Markdown | ~22,000 | Yes — Room left for prompt + response |
ACK handles that conversion automatically for every document in your knowledge base.
AI Context Keeper is powerful for individuals. When you want your team on the same page, it's built for that too.
Create workspaces your team can access. Everyone draws from the same knowledge.
Decide who can view, edit, and share within each workspace.
Pro includes 5 members. Premium includes 10. Add more at $2/month each.
If you're technical (or have someone technical on your team), our API and MCP server unlock a more advanced workflow.
The API and MCP server let AI tools interact with your knowledge base automatically — not just reading context, but writing back to it.
Think of it as the difference between manually filing papers and having an assistant who reads, organizes, and files everything for you.
Most users get full value from core features without touching the API.
We're building toward a future where your knowledge base does more of the heavy lifting for you.
Upload raw sources and let AI compile structured summaries automatically.
Your knowledge base will suggest links between related documents.
Periodic scans to flag outdated info, find contradictions, identify gaps.
Type a question and get answers synthesized across everything in your library.
Connect your Google Drive and import documents directly.
Access and build your knowledge base from your phone.
Every AI conversation should build on the last one. Start your free knowledge base in 5 minutes.
