Logically
An AI workspace for citation-backed research, reference management, PDF annotation, literature review, and academic writing.
About Logically
Logically is the current official product name for the research workspace previously known as Afforai. It brings an AI research assistant, reference manager, document writer, PDF annotator, shared libraries, and citation tools into one browser-based workflow. The strongest fit is academic or evidence-heavy work where the user needs answers tied to sources rather than unsupported AI text. A researcher can upload PDFs, URLs, DOI records, or imports from other reference managers, organize material with folders and tags, ask questions across selected files or Semantic Scholar results, annotate documents, and move useful findings into a draft. The product is less compelling for people who only need a general chatbot or a lightweight citation generator, because its value comes from keeping research material, writing, citations, and collaboration connected. Pricing is freemium: the official pricing page promotes free use without a credit card, while the Unlimited plan unlocks unlimited AI usage, premium models, premium export and bibliography features, and larger storage terms.
Best for
Best use cases
Building a literature review from uploaded PDFs, DOI imports, and Semantic Scholar searches before drafting a paper.
Moving a Zotero, Mendeley, or EndNote library into a workspace where references can be tagged, searched, cited, and discussed with AI.
Annotating a dense PDF, asking AI about highlighted passages, and inserting useful notes into a draft document.
Writing a paper section while pulling citation-backed suggestions and automatic bibliography entries from the same research library.
Coordinating a shared reference library for a class, lab, or research group with invitations, permissions, and ownership transfer.
Compare before choosing
Compare with Zotero or Mendeley if your main need is mature reference management, offline library control, or established desktop workflows.
Compare with Elicit or Consensus if the main job is systematic literature discovery, evidence extraction, or screening papers before writing.
Compare with ChatGPT, Claude, or Gemini if you need a general assistant rather than a research workspace with citations, PDFs, and libraries.
Compare with NotebookLM or PDF-focused chat tools if the workflow is mostly private document Q&A and does not require reference management or document writing.
Features
Pros
- Combines research discovery, document Q&A, reference management, annotation, and writing instead of splitting them across separate tools.
- Official help content emphasizes inline citations and data sources, which is important for academic and evidence-heavy work.
- Supports imports from Zotero, Mendeley, and EndNote through standard export formats, reducing migration friction.
- Free access lowers the trial barrier, while yearly Unlimited pricing is clearly shown in the current official pricing UI.
- Team and shared-library features make it more suitable for labs or departments than a solo PDF chat tool.
Cons
- The official site is JavaScript-rendered, so some pricing and feature details are easier to verify from the rendered app or bundled code than from plain HTML.
- The old Afforai name still appears in help links, infrastructure URLs, and some support resources, which can confuse procurement or citation of the product identity.
- Unlimited storage has a terms-linked note saying it starts at 10GB, so very large libraries should verify storage policy before committing.
- Users who only need a general AI assistant, search engine, or mature offline reference manager may find the all-in-one workspace heavier than necessary.
