Audience
Researchers, students, writers and professionals who need source-linked research articles, independent AI perspectives and a saved research library.
About Ithy
Ithy — I Think Why — turns research questions into articles with sources. Fast Research provides focused answers. Deep Research preserves separate AI researcher perspectives and combines findings into a final article.
Users can inspect source links and passages, save a library, organize folders and download HTML. Pictures, video, charts and maps depend on the question, evidence and settings. New answers start private; link sharing and public search publication are separate choices.
Free access is available. Pro costs $20/month or $120/year, billed annually, with 1,000 answers/month under current allowances. Ithy runs in desktop and mobile browsers. Founded by Winson Luk in November 2024.
AI answers can contain errors; check important claims and original sources.

Watson Discovery is AI-powered search and text-analytics that uses innovative, market-leading natural language processing to understand your industry’s unique language. It finds answers in your content fast and uncovers meaningful business insights from your documents, webpages and big data, cutting research time by more than 75%. Semantic search is much more than keyword search. Unlike traditional search engines, when you ask a question, Watson Discovery adds context to the answer. It quickly combs through content in your connected data sources, pinpoints the most relevant passage and provides the source documents or webpage. A next-level search experience with natural language processing that makes all necessary information easily accessible. Use machine learning to visually label text, tables and images, while surfacing the most relevant results.

Agent Bayes
Agent Bayes is an AI research assistant for graduate students, postdoctoral researchers and other academics. Users add papers as PDFs or sync them from Zotero, then ask questions about their library. The agent searches those sources and builds a mindmap of claims, each linked to the passage and page supporting it. Users can open a citation to inspect the passage or PDF page, and competing findings can remain on the map as separately sourced positions. AI Verification assesses whether cited passages support a claim; the feature is included in paid plans. An MCP server lets compatible tools such as Claude Code, Codex and Cursor search the user's library and work with its cited answers and mindmaps. The free plan includes 50 credits per month, and paid subscriptions start at $11/month, billed annually.

ScholarIQ
ScholarIQ is a web-based AI research assistant for searching and reviewing scientific literature. Researchers can pose a question, search records from OpenAlex, ORCID and PubMed, or upload search results and source documents. The platform ranks articles against review criteria, supports citation-based snowball discovery, and helps users screen records, highlight relevant passages, and extract specified information from uploaded texts. Answers and suggested values link to cited sources, while reviewers retain control of inclusion decisions, risk-of-bias judgments, and conclusions. ScholarIQ records reviewer identity, decision rationale, and supporting passages to make review work traceable. It also provides a public research metadata atlas linking papers, researchers, journals, institutions, and topics. It serves individual researchers and review teams doing literature searches, evidence screening, and systematic reviews.
