Documents that keep piling up,
turned into knowledge that answers when you ask.
Business plans, contracts, research notes, review memos. Upload the PDFs, Office files and Hangul documents scattered across your drive and chat apps into one place, and get back answers with the document name and page attached. Who changed what, and when, is kept too.
No credit card, start for free. We're taking early-access requests before signup opens. Start alone, and once a team forms, just widen who can see it.
Not a tool for writing new documents —
a repository for the documents you already have
Different from a note-taking app, and different from a tool that answers questions about a handful of PDFs. We'll tell you honestly which one fits.
This fits if
- You have hundreds of PDF, Hangul and Word documents piling up, and more keep coming
- You ask "which document was that in?" every week, and answers need a source
- You work with documents where versions and history matter, like contracts and submissions
- You want to open, edit and share PPT/Excel/Hangul files as-is, without retyping them
- You'd like scanned paper documents to be searchable too
- You're starting alone but expect to share with a team eventually
A different tool fits better if
- Your main use is writing and organizing new notes — a note-taking app fits
- You just need to summarize two or three PDFs once, then you're done
- You need an organization-wide rollout with approval routing, audit logs and data connections. See the PAASUP ACE
Your team's documents are only organized in a few people's heads
It's not a problem while the team is small. But once material piles up and people change, the same person ends up answering the same question every time.
- Startups
- Research labs
- Legal & IP
- Accounting & consulting
- Any team with a lot of documents
"Where's that file again?"
Material is scattered across five different places
Shared drives, personal laptops, chat attachments, inboxes. You can only ask the one person who remembers where it went.
"Is this actually the final version?"
Nobody's sure which one is current
plan_final_v3_actually_final.pptx. Without a record of who changed what and when,
you end up making the same confirmation calls every time.
"That was the person who left, so…"
When people leave, the knowledge leaves with them
Contract terms, submission history, response standards. Even if it's on record somewhere, if you can't find it, it might as well not exist.
Don't retype it.
Open, edit and share the file as it is
No organization-management features to wade through — just documents and knowledge. Every screen below is an actual product screen.
View 8 file formats without downloading them
PPT, Excel, Word, Hangul, PDF, CSV, Markdown, JSON. No more downloading a file just to check it, or being unable to open it because you don't have the right program. Turn pages and search inside documents right in the browser.
Every change is kept, and you only see the pages that changed
Who changed what, and when, is recorded automatically. Office documents like Word and PowerPoint are compared against the previous version to show which pages and sentences changed, so you're not re-reading all 40 pages from scratch.
Share a document or folder with a single link
No more sending files one by one. Share a whole folder as a link, and set its expiry, a 4-digit password, and how much can be downloaded. Recipients can view it right from their phone — no signup needed.
A repository just for you
Only you see your own documents. Start in a personal repository fully separate from any shared one, and move only what you choose to publish into a team space.
Large files and scanned copies, as they are
Scanned contracts, tens-of-megabytes proposals, engineering drawings. No need to store them separately because of size or format — keep them alongside your other documents, and see each one's processing status.
Find it, ask about it, and get a first draft
Finds sentences with the same meaning even when the wording differs, alongside keyword search. Answers are grounded in your own documents, and you can turn that answer into a new draft and keep only the parts you want.
Edit with the program you already use. No downloading and re-uploading round trips
Click Edit, and your Hangul, Word, PowerPoint or Excel app on your own PC opens the file directly. Save in that program, and it's uploaded as a draft right away — click Apply, and it's recorded as a new version. Works on both Windows and Mac.
Connect your own AI tool to your repository
Connect an MCP client like Claude Desktop, and it searches and cites your documents inside that same tool, under the same permissions — no need to open yet another chat window. Issue a token from your account settings and just add the server address.
Not just search — it reads and answers
The moment you upload a document, it goes through processing suited to its file type and becomes knowledge. Below are the actual stages one file passes through.
You can check the processing status per document, so you can tell what's already searchable from what's still being processed.
Reads Hangul documents and scanned paper too
HWP files from government-support paperwork, and scans or image PDFs with no embedded text, are turned into readable text through character recognition. Upload a plain scan of a contract, and it becomes searchable too.
Understands tables and charts as sentences
Tables of raw numbers, and org charts or flowcharts drawn as images, are also turned into a written explanation kept alongside them — so you can ask "what was that value in that table?"
Shows the source document and page alongside the answer
It doesn't just hand you an answer. It also shows which document and page it came from, so you can open the original and check it right away.
You can trust us with it
Since this service handles contracts and submitted paperwork, security isn't a feature — it's the baseline. It's operated directly by PAASUP, a B2B platform company certified to the international information security management standard ISO/IEC 27001:2022.

Encrypted at rest and in transit
All traffic is encrypted over TLS, and documents and attachments are kept server-side encrypted in cloud storage. Passwords and connection keys are stored only hashed or encrypted.
Isolated cloud infrastructure
Runs inside an isolated network (VPC) on AWS, with server access allowed only through security groups and keys. The database is never reachable directly from outside.
Monitored and logged around the clock
Server resources and errors are monitored continuously, with alerts firing the moment a threshold is crossed. Who opened or downloaded which document, and when they logged in, is kept on record for after-the-fact review.
Your documents are yours; team documents stay within permissions
Nobody but the owner — not even an administrator — can view a personal repository's contents. Team repositories set who can see them at the repository and folder level, and search and answers stay within that same permission boundary.
Never used to train AI models
Documents and questions you submit are used only to generate your answer, never to train an AI model — guaranteed by contract terms with our AI model providers.
Minimal personal data, handled as disclosed
Only the email and name needed to sign up are collected. Our collection, use, retention and deletion standards are published in the Privacy Policy, and data is deleted on request when you leave.

Four steps, and you're done
No adoption consulting, no taxonomy design needed. Sample documents and suggested questions are ready right after signup, so you can get your first answer immediately.
Upload your documents
You can upload a whole folder at once. PDF, Hangul, Word, scanned PDFs — as they are.
It reads them automatically
Uploaded documents are processed automatically and become searchable and askable. No tagging needed.
Ask
Ask in plain language, like "what were last year's contract renewal terms?", and get an answer with the source document attached.
Keep it as a document again
Save the answer you got as a new document, and that document becomes knowledge for the next question too.
On your phone, snap a photo, upload it, and ask
Photograph a paper contract, a business card or a whiteboard with your camera, upload it, and ask the AI about it right there, photo in hand. Scanned PDFs you've stored are searchable on mobile too — right before a meeting, ask "what were that contract's renewal terms" and check the source page. Shared links you receive also open directly on your phone, no signup needed. Save the editing and organizing for your PC.
Start alone, grow into a team, then an organization.
You don't need to roll out a company-wide system from day one. Expand only as far as you need, and whichever stage you're at, the repository you've been using stays the same.

Team adoption
We're looking for early users
A shared team repository is opened after a short conversation. It's enough to tell us where your documents currently live, and roughly how many people will be sharing it.
It's enough to tell us where your documents currently live. We'll review your setup and reach out individually once we're ready.
- Setting up your team space and inviting members
- Checking in advance whether it fits your team's documents
- If you need an organization-wide rollout, we'll point you to the PAASUP ACE
