Ask plain-language questions about company history and decisions, and get streamed, citation-backed answers pulled from Slack.
AskTiz turns an organization's Slack workspace into a searchable knowledge base, continuously indexing conversations and letting employees ask plain-language questions about company history, technical decisions, and documentation instead of scrolling back through old threads.
Under the hood it combines hybrid search (full-text plus vector similarity), AI reranking, and retrieval-augmented generation, then streams Claude-generated answers with inline citations linking straight back to the original Slack messages, so answers stay traceable to their source.
