Save what you know. Find what you don't.

TextData is an online and open-source platform that helps you save what you know and find what you don't. Use our website or Chrome browser extension to form communities, bookmark webpages, and take notes to create and save online information.

Then, using everything that you and your collaborators have saved, we'll help you find old information, ask and answer questions, and contextualize new information.

What does TextData Provide?

Below, we describe how TextData helps you create, save, and find online information.


Form Communities

A community is where you save information. A community consists of any number of users, all generally interested in a similar topic. Learn more.

Create a Community

Make one for private personal archives, for class notes, for working on a class project, or for thoughts on interesting articles.

Join a Community

You can join a community by copy-pasting the community join key (accessible from clicking the 'Key' icon).

Collaborate with Others

All information saved to a community is accessible by any member of the community, and only members of a community can see the content.


Create and Save Information

Create markdown-style notes and save them to any of your communities. Learn more.

Optionally Add an External URL

Adding a Submission URL will link your notes to an external webpage. Use this to take notes with respect to something online (e.g., a lecture video).

Add a Title and Description

The title should briefly describe the note's purpose, and the description can be whatever you like.

Submit from Anywhere

You can create submission from the website and from the Chrome browser extension.


Find Information

Search, view recommendations, ask questions, and more from the content submitted to your communities. Learn more.

Search and Browse Your Communities

The submissions to your joined communities are searchable using the search bar on the website or in the extension.

Get Recommendations

View your recommendation feed on the homepage or open the extension on a webpage to see contextual recommendations. Open the extension with highlighted text to see submissions tailored to your selected context.

Interact in Context

Use the extension to ask questions in context, summarize selected text, and drive curiosity with automatically generated questions.


Interact with Submissions

Visit a submission's TextData-specific page to read, reply, visualize, share. Learn more.

Edit, Delete, Share

You can edit a submission, add or remove it from a community, delete it entirely, or provide feedback.


Replying to a submission will create another submission and display it beneath the description. This way, any future user who visits this submission will see your reply


See how similar submissions are related by interacting with the graph.

For some pages, your highlighted text will not be captured by the extension. You can tell that this is the case when the “Highlighted text” area doesn’t display any text. If you want to save the highlighted text in the context or ask a question about the highlighted text, then first copy-paste it into the field right below the highlighted text display.

You can add a fragment in the URL. For example, if you would like to submit page 9 of this PDF, you can add “#page=9” to the end of the URL in the address bar. That results in this link. Once you do this, you can open the extension, and it will pull the URL with the fragment for a submission.

If you want to make a submission at a specific time, you can change the webpage URL to include the video time (right click video → copy URL at current time → paste into address bar). Once you do this, you can open the extension, and it will pull the URL with the fragment for a submission.

You can highlight the transcript and open the extension, and it should register the highlighted text.
