Add the material
PDFs, websites, YouTube transcripts, pasted text, and markdown go into one notebook. SourceLab extracts the text, splits it into passages, and indexes them.
A notebook for your own sources
A notebook that answers from your sources
Add a PDF, website, YouTube transcript, or notes. Ask a question, then open the passage the answer came from, including the page on a PDF.
Features
Built from the sources you add
A notebook holds your material. Chat and study tools stay tied to those sources.
Answers you can check
Each claim can open the passage it came from. On a PDF, the citation includes the page.
Memory across notebooks
SourceLab can recall what you have already worked through when you ask again later.
See how an answer was found
Open the steps above a reply: the search, the passages that came back, and whether the answer stayed on those sources.
Study tools
Use the same sources to study
Generate a study aid from the notebook instead of rewriting the material yourself.
Cited chat
Ask in the notebook and follow a citation back to the source.
Flashcards and quizzes
Practice from the sources, with an explanation on each quiz answer.
Mind maps
Expand a map of the material and ask about a selected node in chat.
Summaries and reports
Get a summary, key takeaways, or a longer report from the same sources.
Who it’s for
For people working through a set of sources
Students, researchers, and anyone who would otherwise reread the same files.
Students
Keep a course packet, lecture notes, and videos in one notebook, then quiz yourself from them.
Researchers
Ask a set of papers a specific question and open the page instead of searching the PDF again.
Project work
Drop in docs and videos for a project and check a claim against the source that said it.
How it works
Look up the notebook, then answer
SourceLab searches the notebook when you ask, instead of answering from general knowledge. Web results, if you turn them on, are marked separately from notebook citations.
Step 1
Add sources
You add files and links. SourceLab splits them into passages and prepares those passages for search.
Step 2
Index the notebook
Each passage is embedded and stored in that notebook’s index, so a later question can find it.
Step 3
Answer with a citation
The question retrieves the closest passages, checks the match, and the reply points back to them.
