Quick verdict
Bottom line up front: Logically — the research assistant formerly known as Afforai — bundles a reference manager, a PDF annotator, and an AI document writer into one workspace, with chat that answers from your own library. The free plan caps every kind of AI help at 5 uses a day. For researchers who live in PDFs, Unlimited at $12 per user/month billed annually is easy to justify; just know the product renamed itself, and older Afforai pricing around the web no longer applies.
What does Logically do?
Logically combines four tools researchers usually buy separately. The Reference Manager stores papers, auto-extracts metadata, and cites in 10,000+ styles with automatic bibliographies. The File Annotator lets you highlight PDFs and download them with annotations included. Logically AI chats with selected files, or searches Semantic Scholar and the web, answering with inline citations. The AI Document Writer drafts with autosuggestions that cite from your library. Mini Tools (citation generator, paraphraser, summarizer, grammar checker) round it out; uploads include PDF, EPUB, DOCX, PPTX, TXT and Markdown, plus URLs and DOIs.
It sits closest to Elicit, which specializes in extracting data tables from papers, and Paperguide. Logically’s pitch is breadth: references, annotation, and writing in one subscription instead of three.

What the pricing page doesn’t make obvious
Two details matter. First, the rebrand broke the internet’s price memory: directories still list Afforai’s old Unlimited tier at around $8/month, but Logically’s current page shows $12/month on annual billing, plus a separate $600/year Frontier tier. Second, the student discount has a clock on it: Logically’s pricing FAQ says the 50% student coupon — earned with a university email after completing the product tours — expires 72 hours after you complete the tours. Tour the product “to decide later” and you can quietly lose half the discount. Paid plans carry a 30-day money-back guarantee.
What are Logically’s strengths?
- One workspace instead of four subscriptions: a paper moves from library to annotated PDF to cited draft without exports.
- Citations are structural: 10,000+ styles, auto-populated references on upload, and answers that point back to their sources.
- Honest free plan: no credit card, all four products, and daily (not one-time) AI allowances.
- Model choice on paid tiers: Unlimited unlocks advanced and reasoning models; Frontier adds frontier Claude, GPT and Gemini models with adjustable effort.
What are Logically’s weaknesses?
- The free caps bite fast: 5 chat messages a day disappears inside one literature-review session, and free bibliographies are limited to 2 entries per document.
- Rebrand residue: Afforai links and lifetime-deal expectations still circulate, and old terms do not automatically map onto new plans — check your account.
- Frontier is a big step up: at $600/year, most individual researchers will never need its model tier.
Who is Logically for?
Graduate students, academics, and R&D professionals who manage a real paper library and write from it — especially anyone juggling a reference manager plus a separate chatbot subscription. If your research is occasional, Consensus on its free tier may cover you without another workspace to maintain.
Frequently asked questions
Is Logically the same product as Afforai?
Yes. Afforai rebranded to Logically; the old domain redirects, and Afforai Inc. remains the company behind it. The current product is broader than the original document-chat tool.
Is Logically free to use?
Yes. The free plan needs no credit card and includes all products with standard models, capped at 5 AI autosuggestions, 5 chat messages, and 5 AI commands per day, with 100MB of storage.
How much is Logically Unlimited?
$12 per user/month billed annually, per Logically’s pricing page checked November 1, 2026. A 30-day money-back guarantee applies; eligible students get 50% off the first year, but the coupon expires 72 hours after completing the product tours.
Verdict: is Logically worth paying for?
Yes — for active researchers, Unlimited at $12/month billed annually replaces several overlapping subscriptions with one workspace for the full read-annotate-write loop, and cited answers make its AI output easier to trust than a bare chatbot’s. Casual users should stay on free: the caps make it a sampler, and the value only appears when a paper library is your day job.
