Workflow

Build the material you want to think with.

Libraries define your research space, shape the material inside them, and let you control search scope with precision.

Step 1 - Create a library

Create a library for the domain you want to explore.

Build clear research containers first, so each search starts from a deliberate body of knowledge.

Step 2 - Add and shape content

Add and shape the material behind each library.

Bring in the sources you want to think with, then choose one or multiple libraries per search to narrow or expand scope with precision.

Step 3 - Define scope for each search

Choose exactly which libraries to search before every query.

Select one focused library or combine multiple domains in the same search. Scope stays explicit at query time, so each result set reflects the material you intentionally selected.

Step 4 - Search by concept

Find ideas even when the wording is different.

ConceptSeek searches by meaning, not just exact keyword matches. You can phrase a question naturally and still surface relevant passages across transcripts, videos, and research notes.

Step 5 - Review overview and synthesis

Get a grounded overview built from retrieved evidence.

Each search returns a synthesis of how the concept appears in your selected sources. The overview is tied to concrete passages, helping you build arguments from evidence instead of assumptions.

Step 6 - Open the exact moment

Jump to the original source at the right timestamp or location.

Open any result directly where it appears: a precise video timestamp, transcript location, or source segment. Verify context immediately without re-searching or scanning manually.
