Chat with any PDF, video, or website and get cited answers in seconds
Every response is anchored to your source document with clickable citations that scroll to the exact passage, so verification takes seconds instead of page-by-page searching.
Organize documents into folders and query many files in a single conversation to compare arguments, cross-reference findings, or study a whole syllabus at once.
Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language.
Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.
Your judgment, answering the team when you can't
Meetings, documents and the tools a team already uses are ingested continuously, so the clone learns from the same material the team works with. A Transcript feature records and transcribes meetings.
Everything is turned into a named thing — people, clients, projects, decisions and rules — including the decisions that were considered and rejected, which usually carry the most context.
The knowledge graph stores the latest decision on each subject along with whatever it superseded, so answers reflect current policy rather than stale documents.
The 'yokai' agents check the graph before answering, and are reachable inside Hakutaku chat, through the Agent Builder, and from Claude or ChatGPT via MCP.
