FAQ
Frequently asked questions
- What is ConceptSeek?
- ConceptSeek is a semantic search workspace for long-form content. You build private libraries from your sources — YouTube videos and text notes — then search across them by concept. Results are exact passages from your own content, not AI-generated answers.
- How is ConceptSeek different from ChatGPT or Claude?
- ChatGPT and Claude generate text responses, which means they can hallucinate or paraphrase inaccurately. ConceptSeek does not generate answers. It retrieves verbatim passages from the sources you have added, with the source title and — for YouTube — the exact timestamp. Every result is directly citable.
- How is ConceptSeek different from NotebookLM?
- NotebookLM uses your sources as context for AI-generated responses. ConceptSeek returns the actual text — no generation, no paraphrasing. The difference matters when you need to cite: ConceptSeek results are the original words with the original source attached. See a full comparison →
- What sources does ConceptSeek support?
- Currently: YouTube videos and plain text notes. When you add a YouTube URL, ConceptSeek fetches the transcript automatically. Text notes are pasted or typed directly. PDF import and web link scraping are not yet available.
- How does YouTube search work?
- When you add a YouTube URL, ConceptSeek retrieves the video's transcript, splits it into timestamped passages, and builds a semantic index. Search results show the exact passage and the timestamp so you can navigate directly to that moment in the video.
- Does search use keyword matching or semantic/vector search?
- Both. ConceptSeek runs a two-stage pipeline: PostgreSQL full-text search for lexical precision, followed by vector similarity search using OpenAI embeddings for conceptual relevance. Results from both stages are merged and ranked. This means you can search for the exact words or the underlying idea.
- Can I search across multiple sources at once?
- Yes. You select one or more libraries to search across. All sources within those libraries are searched simultaneously, and results are ranked by relevance regardless of which source they come from.
- What is a Library?
- A Library is a named collection of sources you group together. You might create one library per project, topic, or research question. Search always runs within the libraries you select, so you control the scope.
- Who is ConceptSeek for?
- Researchers, journalists, students, and knowledge workers who deal with large volumes of long-form content and need to locate specific ideas, arguments, or quotes precisely — with the source verified. It is built for people who need to cite, not just summarise.
- What happens to the content I add?
- Content you add is stored in your private account. It is not shared with other users, not used to train models, and not accessible outside your account. Transcripts and embeddings are stored in a dedicated database tied to your user ID.
- What is Founding Member status?
- Founding Member status is for early supporters and includes launch perks such as a permanent badge and discounted paid plans where applicable. ConceptSeek is now live, so account access follows your active plan. See the Pricing page for tiers and pricing.
- Is there a free plan?
- Yes. ConceptSeek has a free plan with core access to the app, plus paid plans with higher limits for libraries, sources, and monthly credits. See current plan details on the Pricing page.
- Where can I see pricing?
