Map concepts across your sources.

YouTube videos • YouTube playlists • YouTube channels • Podcasts • PDFs • Text documents • Direct text notes • 

Built to inspect research, not just summarize it.

Six capabilities, shown as live interface previews from the relational map to your libraries.

Threads

See where your sources converge, diverge, and contradict around a claim. Threads turns the connections in your library into a relational map, so you can visualize the evidence and compare sources more intuitively than a flat summary.

What could you use ConceptSeek for?

ConceptSeek helps you study serious topics across trusted sources, recover ideas you cannot easily keyword search, and navigate long-form material with much greater precision.

Research a topic across trusted sources

Find the exact moments a subject is discussed across the videos, podcasts, documents, and articles you have already chosen.

Recover ideas without exact keywords

Search by concept, not just wording, and surface relevant passages even when you do not remember the precise phrase.

See how sources connect

Trace where your materials converge, diverge, or contradict one another without having to read or watch everything in full again.

Create a personal knowledge library

Bring together the sources you trust and turn them into a structured library you can search by topic, concept, and connection.

Test a thesis against evidence

Compare your idea with trusted content and quickly find the passages that support, refine, or challenge it.

Make long-form research usable

Turn scattered videos, lectures, PDFs, notes, and articles into a searchable library that becomes more valuable over time.

AI where it helps. Sources where it matters.

ConceptSeek uses a mix of deterministic and AI systems to find, compare, and rank every moment. The passages stay visible and directly accessible. The thinking stays yours.
