A drive that files the document and cites the page
Upload a pile of files, have them land in a folder a person would recognize, and answer a question with the page it came from.

Difficulty is an editorial estimate of technical and operational complexity, not a score.
Startup idea analysis by Startup Ideas. Last reviewed Oct 6, 2026. How we read a launch.
The startup idea
Jevbox is an open-source document drive from the Extend team. The post says you upload a file and it is categorized into a folder tree, that a question is answered by picking a folder, then a document, then a section, and that every answer cites the page. It also says access is checked at retrieval, and that an MCP server lets an agent see the same documents a person is allowed to see. The repo is public.
The opportunity is not a better search box on a drive nobody opens. It is the moment a question has to name its source. A team will trust an answer that points at a page they can open. They will not trust a paragraph that could have come from anywhere. Permissions are the product: if someone loses the file, they lose the answers built on it. That is a harder company than a chatbot over a PDF.
Because the launch is open source, a business beside it is hosting, a private folder for one kind of document, or the review step a regulated team needs. The count itself is not the company.
The problem
Company knowledge is a shared drive nobody trusts, so people ask a colleague instead of searching.
Who would pay for this?
- Primary
- A team that already lives in documents and will not paste them into a public chat.
- Secondary
- The person who currently gets asked where the latest version is.
- Early adopter
- One team’s real folder, not a demo corpus.
How could it make money?
Possible models. Nothing here is a claim about what Extend charges.
- The post says it is open source and can be self-hosted. A paid layer is hosting, or a folder with the review a company requires.
- Do not charge for a citation by itself. Charge when someone wants the drive kept for them.
What would the MVP look like?
- One folder of real files.
- An answer that names the page and the section.
- A person who loses the answer when they lose the file.
- No second source until the first folder is the one people actually ask about.
How to validate the idea
- File one week of a real team’s documents by hand, using the folders you think the product should invent.
- Ask ten questions they already ask each other. Count how many answers you can point at a page for.
- If they still message a colleague, the citation is not the thing they needed.
How to differentiate
- One kind of document, such as contracts, specs, or policies.
- The page is the product. A summary without it is a chat.
- Permissions match the file. Do not build a second access list.
- Leave the editor to the tool they already write in.
Original product launch
This launch is inspiration and evidence that someone shipped, not a partnership. The idea above is our reading of the broader opportunity. Extend did not write it.

Product that inspired this idea
An open-source document drive that files what you upload, answers questions, and cites the page. The post says permissions follow the source, and that it ships with an MCP server.

Show which coding session is working, which is stuck, and let a person reply without opening the app.
- Human-looking cursors for computer-use agents
A small open library of mouse motion so an agent cursor does not look like a teleport.
- A browser inside the coding agent’s terminal
Open a real browser from the agent session so the agent can see the page it just changed.
- A coding agent that runs a small model in the browser
A coding assistant that runs locally in the browser on a small model, for people who will not send the repo out.
