AI DOCUMENT SEARCH · PERSONAL KNOWLEDGE MANAGEMENT
Where the contract is, what was decided in the last meeting, and what changed in the latest document.
ASTERON KMS continuously indexes Windows work folders and HWP, PDF, and Office files, searches them by content and meaning, and returns AI answers linked to the original evidence.

THE HIDDEN WORK
Open the mailbox, change the search term, and check the attachments one by one.
The file name alone is not enough, so I end up trying to open several documents again.
Whenever we have a meeting, we review material that we have already read from the beginning.
“This project has been in progress since last year...”
Explaining contextSelect the file, upload it, and explain the context of the company and project again.
Your work data is already sufficient. The problem was that there was no system to remember it.
KMS, WITHOUT THE PROJECT

FREQUENTLY ASKED QUESTIONS
ASTERON KMS is a personal knowledge management program for Windows that indexes your work folders and connected documents, searches them by content and meaning, and answers questions with links to the source documents.
It searches HWP, HWPX, PDF, Word, Excel, PowerPoint, CSV, and text files. It can also connect supported email, calendar, Google Drive, Notion, and Microsoft 365 sources.
No. Original local files stay in their existing folders, and search indexes are stored on the user's PC. When cloud AI is enabled, only the context needed for the question may be sent to the selected model.
Yes. ASTERON KMS connects answers to the documents and passages used as evidence so you can return to the original source and verify the result.
Yes. Personal Lite is free and includes automatic folder indexing, keyword search, Alt+Space quick search and basic alerts. Mail, Drive, Notion, Microsoft 365 and calendar connections, asking your documents and semantic search start with Standard.

YOUR WORK, ALREADY UNDERSTOOD
01 · SEARCH & KNOWLEDGE
Contracts, quotes, emails, meeting minutes and cloud documents are searched at once. Instead of having to re-read the materials you find one by one, you can summarize them on the spot, extract the amount, check the period, add evidence, and ask questions.
From work manuals to technical documents, papers and lecture materials. Find what you need in the documents you already have, and check the source of every AI answer in the original.
Instead of hunting for the right chapter in a thick operations manual, ask for the steps directly. The manuals the answer used collect in the source documents panel, where you can expand the exact passage.
No need to page through a long API specification. Narrow the scope to that one spec, get the authentication flow and required parameters in one answer, and expand the passage it came from.
Ask what your own lecture materials say, not a generic explanation. The answer shows which materials it came from, and you can open the original file right away.
The document names and content in this demo are fictional samples made for illustration.
Sources are not mixed. Each result is divided into local documents, mail, calendar, Drive, Notion, OneDrive, and OneNote, and clicking them takes you to the source managed by the user.
Register multiple folders and follow changes with real-time file monitoring and coordinated scanning at startup.
Incrementally synchronizes Google Docs/Sheets/Slides and PDF/Office files in the selected folder.
Search shared pages, subpages, and database rows and properties as they are structured.
Index OneDrive documents and OneNote pages, and also merge Outlook calendars into the search scope.
Use both search for exact words and search for content with close meaning, without losing the location and source of results.
When the app is on, it detects creation, modification, deletion, and movement, and any changes made while it was off are caught up the next time it runs. Files that have not changed will not be read again.
Read business documents, including HWP·HWPX, through to the text and find them considering the Korean format. Scanned PDFs can be processed through OCR to make text in images searchable.
If the exact expression of the contract is known, text search is supplemented, and if the expression is different but the meaning is the same, semantic search supplements. Even if you only remember the file name, you won't miss it.
It does not show which document the results came from. Available formats even show page, Excel sheet, and PowerPoint slide locations to reduce double-checking time.
You can now call the Quick Search window while working in another program. Return to the KMS screen and immediately open the document you need without having to navigate through menus.
Summarize documents, extract amounts, and check contract durations from highly relevant results. Save the results you've already created so you don't have to repeat your AI usage even if you click on the same document again.
Draw knowledge maps with local index statistics without AI calls. Browse through multiple views to see key words throughout the material, relationships that appear together, frequently modified folders, and locations where the material is concentrated.
Works even without AI. Knowledge maps and basic searches are handled locally, and you will still be able to find resources even if you turn off Cloud AI or run out of limits.
Find text and related materials that are close in meaning, even if you can't remember the exact words.
Open local files using Explorer, and open cloud files using Drive·Notion·OneDrive·OneNote.
If there is no answer in the search excerpt, open and read the related document, and leave a checkable source for each answer.
NEXT WORKFLOWIf the data keeps accumulating, it's time for the project to remember.
02 · PROJECT INTELLIGENCE
Not only documents in the main folder but also externally linked data, emails, schedules, follow-up actions, and user notes are collected in the same project context. Compare new data based on confirmed values and evidence, and continue the decision and change history to the next task.
As data increases, presence becomes more important than retrieval.
Document 184 · Mail 37 · Schedule 8 · Follow-up 6
Review of contract changes
Check SLA scope
Customer confirmation of delivery date
AI usage does not go away just by opening tabs or viewing lists. Saved documents and status are displayed first, and only functions that require analysis are executed after the user clicks.
Ask only project-scoped questions, see current status briefings, change candidates, incomplete follow-ups and notes all in one screen.
View documents under the main folder and documents linked directly from outside the folder together. Expand the scope of your project without moving or copying the originals.
Collect e-mails connected to the project, and HWP, PDF, and Office attachments received from e-mails are also linked to the project document while maintaining the source.
Manage key project values such as customer, amount, period, and person in charge by section. Each value is linked to a supporting document, and confirmed values are locked to prevent automatic changes.
You can leave a list of project status, risk, and handover reports, and reopen past and new reports as if they were versions.
Beyond file changes and notes, it keeps decisions in time order: which change candidates were applied or dismissed, and which linked mails were sent.
Index all documents under path
Outside folder·Drive·Notion·OneDrive data
Conversations and files linked to projects
Confirmed schedule/follow-up/memo
All functions use the same project data collection scope to avoid briefings, change analysis, and reports looking at different data.
The contract amount or period confirmed by the user is not quietly overwritten even when a new document is received. It is separated into conflict candidates and displayed first.
Determine the up-to-date status of the brief with the project document fingerprint. If there are no changes, the saved version is used as is, and if only some changes are made, it is updated by adding only the changed documents.
AI analysis failure does not spread to documents, specifications, memos, and saved briefing inquiries. The default workspace will continue to open with only local data.
NEXT WORKFLOWConnects requests received by email to actual work on the project.
03 · MAIL TO ACTION
Don't stop at summarizing your mail and drafting a reply. Find to-dos, promised dates, attached documents and related projects and suggest them as candidates for next action.
AI organizes and suggests.
Addition, reflection, and sending are determined by the user.
Screen, search, and AI use a local copy directly synchronized with the mail server. Already received emails can be found offline, and the original emails remain in the existing service.
Connect Naver Hiworks and general IMAP/SMTP accounts to view integrated received mail and account-specific folders. Read, Star, Move, and Delete are reset to the mail server.
Put your mailbox, message list, body, and ASTERON Context panels on one screen. As you read the text, check related projects, materials, and extracted tasks.
Put the title, body, and sender in the same search flow as the document. Search results distinguish between email sources and take you directly to the original conversation.
HWP·PDF·Office attachments in project connection emails are indexed through the existing document parser. Even if there are corrupted attachments, they are isolated to a separate parser process.
Group the same conversations based on References and In-Reply-To. Instead of re-reading long email threads, summarize the entire flow or prepare a reply with selected material.
Sanitize email HTML and display it in a sandbox. Remote images that may contain tracking pixels are blocked by default, and external links are opened in the system browser.
First check the sending address, customer company, project name, and existing thread using the rules. If you are confident, connect it, and if it is ambiguous, leave it as a candidate.
Create a one-time analysis of summaries, requests, deadlines, schedules, and change candidates in your work email and save them to avoid repeating costs when you open them again.
“Request for revised quote by Friday” is shown as a candidate for follow-up, and “Change inspection date to September 22nd” is shown as a candidate for rescheduling.
The actual status changes only when [Add Follow-up] and [Reflect Calendar] are pressed. Manual project linking always takes precedence over the following automatic rules:
Creates a draft based only on the current thread and the document/project specifications checked by the user. Drafts only come to the writing window and there is no automatic sending route.
Requests, schedules, and projects found in the email are all candidates. No tasks, schedules or shipments will change until you approve them.
NEXT WORKFLOWThe confirmed schedule prepares the necessary context in advance of the meeting.
04 · READY BEFORE THE MEETING
Gather local schedules and Google Calendar/Outlook schedules on one screen. Schedule inquiry and rule notifications operate without AI, and related project documents, emails, and current status are analyzed only when creating a meeting briefing.
Connect the external calendar to the KMS schedule table rather than attaching it as a separate screen. So, notifications, projects, searches, and meeting briefings all use the same schedule.
Connect meetings, deadlines, contracts, and other schedules to projects and manage them directly. Schedule inquiry and notifications work without AI.
Direct writing · Project connectionLinks the selected calendar to synchronize changes. Read-only ICS subscriptions are also supported, so you can choose a method that fits your organization's policies.
OAuth Sync · ICS SubscriptionReads your Microsoft account's calendar and uses it to prepare KMS calendars and meetings. The original calendar is managed in Outlook.
Read-only · Automatically reflectedWhen a schedule is approaching, create a readiness alert by checking unfinished follow-ups and the number of documents changed since the previous meeting.
Organize past decisions, recent changes, customer requests, and unresolved issues based on related documents and emails.
Re-find the necessary evidence through project questions, and leave notes and follow-up actions on what has been confirmed.
When new schedules, emails, or documents come in, they become new material for the next notification, change analysis, and report.
Rule detector checks local data every 5 minutes. Notify again only when steps progress or values change, and apply different notification levels for each project.
NEXT WORKFLOWWhen new documents come in after a meeting, we look for differences from the current status.
05 · CHANGE INTELLIGENCE
Read the new document together with the current specification committed to the project. Rather than secretly modifying the confirmed value, AI shows the old and new values, basis location, and whether there is a conflict with the confirmed value for each change candidate and then waits for user approval.
In the Knowledge tab, the customer company, amount, period, conditions and the basis for each value confirmed by the user are used as a comparison standard.
Read documents such as new contracts, estimates, and requirements, and select numbers, dates, conditions, and expressions that are different from the current value as candidates.
Shows the old value, new value, original location, and supporting document. If it differs from the locked deterministic value, it will be marked more strongly as a conflict.
Only candidates you apply become the new current value. Apply and dismiss decisions stay in the History tab so you can retrace them later.
A simple phrase comparison only shows line changes. ASTERON organizes the information based on whether the new material conflicts with the values currently managed in the project.
Displays the old and new values of numbers that directly affect decision-making, such as contract amount, quotation amount, quantity, and unit price, side by side.
Find changes connected to the project schedule, such as start date, delivery date, inspection date, and contract expiration date, and even review the calendar impact.
Condition changes that are difficult to capture with numbers alone, such as maintenance scope, SLA, delivery conditions, and excluded items, are also organized as candidates.
It doesn't just show the AI's conclusions. You can check the original document on which part of the document the candidate was created.
User-locked values are treated with a higher level of trust. Even if different content is found, it is separated by conflict rather than automatically changed.
Whether each candidate was applied or dismissed is kept in the project history. The next brief and report are written from the latest applied state.
It is not compared between new documents, but is based on the current value confirmed in the project.
It also presents what has changed, the location of the original text, and whether there is a conflict with the confirmed values.
Only candidates accepted by the user become the new current state of the project.
NEXT WORKFLOWThe accumulated current status and change history become reports and decision data.
06 · FROM KNOWLEDGE TO OUTPUT
Reassemble project specifications, briefings, documents, emails, follow-up actions, and supporting materials into actual work results. Reports and decision-making data can be modified, updated, and exported even after creation.
Rather than AI speaking confidently,
AI that shows grounds for opposition and even insufficient information.
Once you determine the purpose, audience, period, and table of contents of the report, ASTERON first researches the project facts locally and creates a body with connected evidence.
When an agenda item is registered, related data is collected, alternatives are created, and the scores for each standard, as well as the pros and cons, risks, and grounds for opposition are reviewed together.
8.2/10 · 18% lower cost · 2 counter-evidence items · 1 missing piece of information
After creating a fact sheet through project specifications, briefing, follow-up, records, and document retrieval, use AI at the writing stage to reduce unnecessary calls.
Separate AI's interpretation from the facts confirmed in the document, and leave any parts that lack evidence as items requiring confirmation.
Replace results only after the new section or update is complete. Even if you run into problems while editing, you can still read the reports you've already created.
The contract received today becomes the new basis for the project, the requests in the email become follow-up actions, and the schedule continues with the meeting briefing. The information accumulated in this way becomes the material for the next result.
