What you paste determines how ARC treats it. This choice is not cosmetic.
Firecrawl fetches the page and strips navigation, ads, and cookie banners. ARC records the URL, the retrieval timestamp, and a SHA-256 of what was captured, because pages change and get taken down.
Firecrawl runs the search and brings back each page in full, not a snippet and not a summary. Results are real pages: you get the URL, the text, the retrieval time, and a hash. Nothing is added to the case until you add it.
Paste raw question and answer material: a NotebookLM Q&A, an interview transcript, your own notes. Gemini restructures it. It will not answer a question the source left hanging, it flags contradictions by quoting both sides, and any follow-up questions it suggests are marked as unasked.
