Memory & knowledge for MCP agents
Your AI agent, with a memory that sticks.
Persistent memory and grounded knowledge from your own docs — as native MCP tools your agent calls directly. Drop in any file, URL, or YouTube video; skip building and babysitting a RAG stack. One API, no re-pasting, no token waste.

Your AI forgets everything.
Great model, zero memory. Sound familiar?
Every session starts from zero
Your agent re-asks what it learned yesterday.
Your documents are trapped in PDFs
Formats your model can't read are knowledge it doesn't have.
Your RAG stack is 5 services and a prayer
Vector DB, parser, embedder, reranker — all yours to babysit.
Context is scattered everywhere
Docs in one tool, chats in another, memory nowhere.
The fix
One API that gives your AI a memory.
Nine problems your stack has. One platform that solves them.
Memory your agent calls itself
“Goldfish memory kills good agents.”
remember, recall, and search — as MCP tools your agent uses mid-conversation. It keeps users, preferences, and decisions across every session.
- remember / recall / search over REST or MCP
- Auto-created Memory knowledge base
- Near-duplicate dedup · every memory versioned
Drop in any doc, get it grounded
“If your AI can't read it, it can't use it.”
Any file or URL in, clean Markdown out — chunked, embedded, and searchable. The convert-to-ground flow, without a stack to build.
- PDF, Word, Excel, PowerPoint, CSV, HTML, images (OCR), YouTube
- Batch up to 25 · URL fetch · same-domain crawl
- Scheduled URL refresh — keep sources current automatically
New
Chat with YouTube videos
“Hours of video your AI can't read.”
Paste any YouTube link and the transcript becomes a document your AI can search, cite, and chat with.
- Lectures, talks, podcasts, tutorials — any captioned video
- Transcript lands in a knowledge base like any doc
- Ask questions, get answers with citations
Semantic search
“Keyword search misses how people actually ask.”
Find by meaning, not just matching words — hybrid retrieval that combines vectors and full-text, then reranks.
- Vector embeddings catch paraphrases and intent
- Full-text catches exact terms, codes, and names
- Reranking puts the best passage first
Knowledge bases it actually cites
“Scattered docs mean ungrounded answers.”
Group documents into searchable KBs your AI answers from — with sources, not guesses.
- Grounded chat with cited answers
- Feedback corrections that stick
- Visual graph of connected docs · @mention to scope
MCP-native, wired in one command
“Integrations shouldn't take a sprint.”
The same tools work in Claude, Cursor, and any MCP agent — one install, any model.
- /plugin marketplace add l33tcy/kitforai-claude
- Agent self-setup at kitforai.com/llm-setup
- Same tools over REST
Up to 90% fewer tokens
“Every token you send is cost and latency.”
Your agent pulls only the passages it needs — never a window-burning document dump. Measured up to 90% fewer tokens on real workloads.
- Targeted semantic search instead of whole-KB dumps
- Compact cited results — no JSON bloat or unused metadata
- Lower cost, lower latency, sharper answers
Retrieval built in-house
“Most RAG platforms are thin API wrappers.”
A hybrid retrieval stack built end to end — not a wrapper around someone else's vector DB.
- Hybrid vector + keyword, fused with Reciprocal Rank Fusion
- In-house relevance scoring and reranking
- Fast enough to sit in the request path
Private by default
“Your data isn't someone's training set.”
Your documents stay yours — encrypted, isolated, and never training data.
- Stored files encrypted at rest
- API keys hashed · spaces isolate projects
- Delete means gone — no shadow copies

Clean Markdown from any URL.
Turn any URL into clean Markdown or structured data for AI agents — the article, not the nav bars, ads, and footers around it.
- Works on the real web: JS-heavy, gated, and region-specific sites
- Main-content extraction — clean Markdown, not raw HTML
- Works exactly like files: same output quality, everywhere you use us
https://example.com/blog/building-with-ai .md
# Building with AI Clean, structured Markdown — ready to feed straight into your **LLM, RAG, or agent**. ## Why it matters - No nav, ads, or cookie banners - Tables preserved as Markdown - Works on JS-heavy pages
💡 Use cases

Clean, chunk-ready Markdown for vector stores and retrieval.
AI agents
Feed agents structured context instead of raw PDFs.
Invoice & form extraction
Pull typed JSON fields with your own schema.
Fine-tuning datasets
Turn document libraries into clean training data.
Knowledge bases
Make internal docs searchable and answerable.
Batch processing
Convert at scale via the API with per-key rate limits.

“Pointed the MCP server at Claude and my agent had persistent memory in under five minutes. No SDK, no glue code.”
Sarah K. — ML Engineer
“KB chat cites the exact paragraph it pulled the answer from. Our support bot went from plausible to trustworthy.”
Miguel R. — Founder, devtools startup
“Fed it a 200-page PDF full of tables and got Markdown clean enough to ship straight into our RAG pipeline.”
Priya N. — Data Engineer
“Point it at a URL and it comes back as clean Markdown, not a wall of HTML. I deleted a thousand lines of scraping code.”
Tom H. — Backend Developer
“Spaces keep every client project isolated — each agent only sees its own knowledge bases. Exactly how it should work.”
Aisha B. — AI Consultant
“We replaced a homegrown vector-store setup with knowledge bases. Retrieval got faster and I decommissioned three services.”
Daniel W. — Staff Engineer
“Scanned invoices → OCR → structured JSON with our own schema. It just works, batch after batch.”
Elena V. — Automation Lead
“Best conversion quality I've tested — headings, tables, and code blocks all survive the trip to Markdown.”
Jonas M. — Technical Writer
“Our agents call one API for memory, conversion, and search. One key, one bill, a lot less yak-shaving.”
Ryan C. — Indie Hacker
“Cited answers made compliance review painless — every claim in KB chat links back to the source document.”

Private by default
Your data is yours — never a training set, never resold.
Isolated infrastructure
Runs on dedicated, isolated infrastructure — no shared tenancy.
Encrypted at rest

Scoped API keys
Keys are hashed, per-key rate-limited, and revocable anytime.
Project isolation
Spaces keep each project's knowledge separate — no cross-over.
Delete means gone
Remove data and it's gone for good — no shadow copies.
