Uploading a document as a file comes with two hassles. You have to download your Google Doc as a .docx or .md, and you have to rebuild the file every time you edit the document. As a result, the version you submit often drifts out of sync with the draft you are actively editing.
Google Docs is built for real-time collaboration, which means your document is constantly evolving. The 'last saved file' is never really the latest version — the live document is. Link import is a way to narrow that gap.
Importing via link changes three things. First, there's no step of downloading a file and uploading it again. Second, if you revise your document before submitting, importing the link again picks up the updated content. Third, when multiple co-founders are working from the same link, version confusion drops significantly.

The table below lists the document types you can import by link and the conditions each requires. Check these before importing — unmet conditions will cause an error.
| Document Type | Supported | Required Condition | Notes |
|---|---|---|---|
| Google Docs | Yes (home page link import) | Sharing set to 'Anyone with the link — Viewer' | Only addresses in the docs.google.com/document/d/… form are imported, and only the body text exported as plain text is read |
| Notion page | No link import | — | Upload a file exported as Markdown (.md) |
| Google Slides | No | — | Not a document link, so it can't be imported. Move the content into a Google Doc or a .docx/.md file |
| Google Sheets | No | — | Not a document link, so it can't be imported. Move key tables into a Google Doc |
| HWP or PDF file URL | No | — | File URLs are not imported. Upload PDF (up to 20MB) and HWP/HWPX (up to 4MB) through the upload area after signing in |
| Private Google Doc | No | — | Set sharing to 'Anyone with the link — Viewer' and try again |
For Google Docs, change the sharing setting to 'Anyone with the link — Viewer' before importing. With any other setting, the link won't give OpenSeed access to the text. Notion pages are not imported by link; export the page from Notion as Markdown (.md) and upload that file in the home page upload area. PDF and HWP/HWPX files can also be uploaded in the same area after signing in.

Below is the complete step-by-step flow, from the Google Docs sharing setting to starting your diagnosis in OpenSeed. The route for Notion users — exporting a Markdown file and uploading it — is included alongside.
- [Google Docs] Open the document you want analyzed and click the 'Share' button in the top-right corner.
- [Google Docs] Set general access to 'Anyone with the link' and the permission to 'Viewer,' then click 'Copy link' to copy the URL.
- [Notion] If your plan is in Notion, open the '… (More)' menu in the top-right corner of the page and select 'Export.'
- [Notion] Choose Markdown as the export format and save the downloaded .md file.
- [OpenSeed] Go to the openseed.kr home page and sign in. Before you sign in, a sign-in prompt appears instead of the area for adding a document.
- [OpenSeed] For Google Docs, press the Google Drive icon button in the row below the upload area to open the link field, paste the URL you copied, and press 'Import.' For a Notion .md file, drag it onto the upload area or choose it from your computer.
- [OpenSeed] When the import finishes, a row with the link address (or file name) and a 'Loaded' mark appears. The content is not previewed on screen, so confirm it's the right document by its address or file name; if not, clear it with the × button and import again.
- [OpenSeed] Check the required consent item and press the diagnosis button. (On the Korean or Japanese home page, if you know which K-Startup call you're applying to, you can first pick an open call with the 📢 button.) From here, the flow is identical to a file upload.
What gets analyzed is the body text exported from your document. Tables or text inside images you've placed in a Google Doc are not included, so write important content in the document as text as well. If the imported text is shorter than 50 characters, you can't submit it.

Here are four errors you may see during a link import, along with how to fix each one. Even if the exact error message looks slightly different, the root cause almost always falls into one of these categories.
| Error | Common Cause | Fix |
|---|---|---|
| 'Couldn't read the document' | Sharing is restricted (private), or the permission isn't 'Anyone with the link — Viewer' | In the Google Docs sharing settings, choose 'Anyone with the link' and 'Viewer,' then import again |
| 'Not a Google Docs link format' | The link is a Google Slides or Sheets link, or the address isn't in the docs.google.com/document/d/… form | Copy the Google Docs address as-is and paste it. Move Slides or Sheets content into a Google Doc, or save it as a file and upload |
| 'The text is too short (50 characters or more required)' | The document has almost no text, or its content is mostly images | Write the key content as text, then import again |
| 'Loading the document is taking too long' | The document is very long, or loading was temporarily delayed | Try again shortly. If it keeps happening, download it as .docx or .md and upload |
If your Notion page uses database-style views — for example, a competitive analysis laid out as a table view — the table may be split into a separate file when you export to Markdown. If those details are important to your analysis, copy the table into the main body of your document as a standard table before exporting. The same goes for a Google Sheet embedded in a Google Doc: don't assume the embedded sheet's content is included in the import, and copy it into the body as a table.

Link import is just the delivery method — the quality of your analysis depends on the structure and content of your document. Even with the same core idea, how your plan is organized determines the range of strengths and weaknesses the report can point out. Before you import, run through the checklist below.
- Is the problem statement in its own section — and does it spend at least a paragraph explaining why this problem matters?
- Is your solution described concretely — with a clear distinction between where you are now and what comes next?
- Is your target customer defined — not 'everyone,' but a specific, narrowed-down profile?
- Is your revenue model or use-of-funds plan written out with actual numbers?
- Is there a team section — with each person's name, role, and at least one line of relevant experience?
- Is the core content written as text, rather than embedded primarily in images or attachments?
- Does what you imported or uploaded match the latest version you're editing right now?
If your document covers all seven points, the report can give specific, item-by-item feedback on each one. Missing sections won't stop the analysis from running, but you'll likely see comments along the lines of 'insufficient evidence to assess this area.' Fill in the missing items in your document before you submit.

Here are answers to questions that commonly come up about link import.
- Q: When I import a Google Docs link, does OpenSeed access my Google account? — No. It only reads the plain-text export address of a document you've made public, without any sign-in credentials, and does not access your Google account or other documents. The imported text is used for the analysis; see our privacy policy for details on data retention.
- Q: Will tables I've inserted as images in Google Docs be analyzed? — Import reads the body text exported from your document, so image-based tables are not included. If an image contains important information, transcribe it as text in the document.
- Q: Can I paste a Notion link directly to import it? — The home page has no button for importing Notion links. Export the Notion page as Markdown (.md) and upload the file. If you need the content of sub-pages, gather it onto one page before exporting.
- Q: Does link import or file upload produce better analysis results? — Analysis quality comes from your document's content and structure, not the delivery method. That said, a scanned PDF can't be read, so prepare text-based documents as .docx or .md, or import them through a Google Docs link.
- Q: Can I edit the content on screen after importing? — There is no way to edit the imported text on screen. Make your changes in the original Google Doc and import the link again.
- Q: Can I use Google Slides, Google Sheets, or PowerPoint? — Slides and Sheets links can't be imported, and PowerPoint files can't be uploaded. Move the content into a Google Doc or a .docx/.md file.
