Paperguide
AI research assistant with semantic paper search
Overview
Paperguide is a research assistant that searches across 100M+ papers, surfaces evidence-based answers with citations, and helps draft literature reviews. Free tier; subscription for higher quotas and team workspaces.
Use cases
What you can produce with Paperguide
- Ask a research question in plain language and get an evidence-based answer with citations drawn from a 200M+ paper index.
- Upload a PDF and chat with it - asking for the methodology, sample size, or key findings and getting answers tied to specific passages.
- Build and organize a reference library, then insert citations and bibliographies in your required style while drafting.
- Extract structured data (populations, interventions, outcomes) from a stack of papers into a comparison table for a literature review.
- Draft a literature-review section with the AI writer, grounded in the papers saved to your library.
- Summarize a batch of papers into skimmable digests to decide which deserve a full read.
- Capture papers from the web into your library using the Chrome extension while browsing journals or Google Scholar.
ASEAN Perspective
Paperguide in Southeast Asia

Paperguide bundles AI literature search, citation-backed answers, a reference manager and an academic writing assistant over a large paper database, putting several research workflows in one tool. The free tier is unusually generous and paid plans ($9-$16/mo) are affordable for students.
It suits students and early-stage researchers who want an all-in-one assistant rather than best-in-class point tools; AI-generated drafts still need human verification for accuracy and integrity. API access is gated to Enterprise, and there is no ASEAN-specific localisation, though the English interface works regionally.
What people say
Paperguide is the 2024 rebrand of ChatWithPDF, founded in 2023 in Alpharetta, Georgia by Mallik Gaddam and co-founders. The pivot took it from a single-trick PDF chatbot to an all-in-one research assistant: semantic search across a claimed 200-million-paper index, evidence-based answers with citations, a reference manager, data extraction from PDFs, and an AI writing assistant. It runs a free tier (10 AI generations a day) with paid plans from roughly $9-12 per user per month, plus lifetime deals sold through AppSumo.
Independent reviewers and users who like it call the combination genuinely useful - one place to search, summarize, manage references, and draft, where competitors make you stitch together Zotero, Elicit, and ChatGPT. The chat-with-PDF lineage shows in its strongest feature: asking questions of an uploaded paper and getting answers pinned to specific passages, which several reviewers say saved them hours and kept hallucination low.
The complaints are real, though. Multiple reviewers found the semantic search underwhelming - some queries return few or zero results where free alternatives like Semantic Scholar surface plenty - which is a serious weakness for a tool whose headline promise is literature discovery. Others describe the interface as confusing, with menus and buttons that make simple tasks harder than they should be. It is also a young, small product: the AppSumo lifetime-deal channel attracts bargain hunters but raises the usual questions about long-term sustainability, and it has nothing like the review depth or institutional adoption of Zotero or EndNote.
Paperguide fits students and early-career researchers who want an affordable, all-in-one workspace and are willing to tolerate rough edges. Researchers whose work depends on exhaustive, reliable literature search should treat it as a supplement to established discovery tools rather than a replacement.
