Show HN: AI tools for high lvl researchers who need assistance – not answers (www.ubik.studio)

Ubik is a researcher-focused AI assistant that emphasizes grounded, citation-backed help rather than authoritative answers. You can @mention PDFs, notes, canvas docs and open-access papers (click-to-add from ArXiv and Semantic Scholar) and have agents highlight source text down to the line, pin quotes, and insert line-level citations into generated outputs. The workspace syncs notes and tagged excerpts so you can generate drafts, summaries or literature reviews with explicit source traceability, or switch to looser ideation modes without citations. Technically, Ubik combines document parsing/OCR, fine-grained retrieval (RAG-style line-level retrieval), and a model-agnostic inference layer that lets you pick from 20+ models for speed, cost, or fidelity tradeoffs. Integration with a 200M+ paper index and in-app citation tooling aims to reduce hallucinations, improve reproducibility, and streamline workflows—supporting both critical close-reading (agents help you interrogate and annotate sources) and rapid exploration. For researchers this means faster, source-grounded writing and literature discovery while retaining manual control of every suggestion.
