## Chat with PDF

Chat with PDF started as a simple promise: stop reading a dense PDF page by page and just ask it questions. The product has since grown into Paperguide, an AI-native research platform, and the old chatwithpdf.ai address now redirects there. The original idea survives as one of the platform's core features, so you can still drop in a paper, a set of papers, or your own library and hold a conversation with the content.

Around that foundation sits the rest of the research workflow. An AI search engine answers plain-language questions from a large corpus of peer-reviewed papers with citations in place. A reference manager imports from Zotero or Mendeley and keeps metadata, notes and annotations in one place. A research agent compares studies and maps a field, data extraction turns many papers into a cited table, and an AI writer produces citation-grounded drafts and themed literature reviews.

The platform leans hard on traceability. Each answer and extracted value is meant to point back to the exact sentence in the source, which matters enormously for literature reviews, journal submissions and evidence work. Pricing runs from a genuinely useful free tier up through per-seat plans for individuals, teams and institutions, with a separate emphasis on auditable systematic reviews and PRISMA reporting.

**Pricing & Plans:** Freemium with paid tiers. The Free plan includes 1,500 AI credits per month, limited reference management and AI searches, and access to Chat with PDF. Plus is about $12 per seat per month billed annually (12,500 credits), Pro about $29 (50,000 credits), Evidence Teams about $89 (150,000 credits), and Enterprise is custom. Annual billing offers significant savings, and prices can change, so verify on the official site.

- **Chat with PDF and multiple papers:** Ask questions across a single paper or several documents and get answers grounded in the full text, with every claim linked to its source statement.
- **AI-powered literature search:** Search a large corpus of peer-reviewed literature in plain language and receive synthesized answers with citations rather than a raw list of links.
- **Built-in reference manager:** Import from Zotero or Mendeley or add papers by DOI, then annotate, store and reuse everything across search, review, extraction and writing.
- **Literature review and AI writing:** Generate a structured, fully cited literature review from your own protocol, drawing on up to 50 papers at a time and organized by theme.
- **Verifiable data extraction:** Pull study details and outcomes from many papers into custom tables where every value traces back to the sentence it came from.

**Strengths:** Chat, search, references, extraction and writing live in one workspace; Answers and extracted values are citation-grounded and traceable to source sentences; Covers a huge corpus of peer-reviewed literature plus your own library; Generous free tier makes it easy to try the PDF chat and search

**Limitations:** It is now part of a larger, heavier research platform rather than a small single-purpose PDF chat tool; Pricing is per seat and can add up for teams; The most advanced systematic-review features are aimed at professional reviewers and institutions; Some features (GDPR, SOC 2, ISO 27001) are still listed as coming soon

## Paperguide

Paperguide has evolved from a general-purpose "chat with your PDF" study assistant into a research platform aimed squarely at rigorous evidence work. Its current centrepiece is Systematic Review: you define a protocol, run a documented search, screen abstracts and full texts with per-criterion evidence prepared by AI, resolve conflicts between two independent reviewers, and finish with verified extraction tables plus a PRISMA flow diagram generated from your own counts. The design principle is that AI prepares evidence but never casts the decisive vote — every screening call, extracted value and synthesized claim is traceable to a named source statement and a human verifier.

The rest of the product supports that workflow from the front end. AI Search answers plain-language research questions across more than 200 million peer-reviewed papers with each assertion linked to its source; the Reference Manager imports from Zotero or Mendeley, adds papers by DOI and fetches open-access PDFs automatically; Extract Data turns a stack of PDFs into a structured, cited comparison table you can export to CSV or Excel; and the Research Agent handles multi-step literature reviews up to 50 papers, organized by theme.

Paperguide also ships an AI Writer for citation-grounded drafting, an MCP integration, and a plagiarism checker, with shared team workspaces that keep papers, annotations and reviews attached to the project rather than to one person's account. It is used by academic researchers along with medical device, HEOR, pharma and government policy teams, and reports over one million researchers on the platform. Pricing runs from a free tier through Plus, Pro, Evidence Teams and custom Enterprise plans billed per seat annually.

**Pricing & Plans:** Freemium with a free plan (1,500 AI credits per month plus limited agents and reference manager) and paid per-seat tiers billed annually: Plus around $12/seat/month, Pro around $29/seat/month, Evidence Teams around $89/seat/month with dual-reviewer screening, and custom Enterprise pricing. Yearly billing advertises savings up to 41%.

- **AI Search over 200M+ papers:** Ask a research question in plain language and get a synthesized answer drawn from PubMed, arXiv, OpenAlex and Semantic Scholar, with every claim linked to its source paper.
- **Auditable Systematic Review:** Run PRISMA-style reviews with a predefined protocol, recorded screening decisions, dual independent reviewers and a conflict resolver, and a PRISMA diagram generated from your actual counts.
- **AI-native Reference Manager:** Import from Zotero or Mendeley, add papers by DOI, and get metadata and open-access PDFs fetched automatically, with annotations and notes that feed every other workflow.
- **Cited data extraction tables:** Define custom extraction columns and have AI fill them across many papers, with each value linking back to the sentence it came from, exportable to CSV or Excel.
- **Citation-grounded AI Writer:** Draft from your own library and 200M+ papers in the same document, switching between 1,000+ citation styles without manual reformatting and without invented references.

**Strengths:** Statement-level traceability: click any claim to land on the exact source sentence; Combines search, reference management, extraction and writing in one workspace; Per-criterion evidence speeds up abstract screening and improves reviewer consistency; Free tier is genuinely usable, and annual billing discounts are generous

**Limitations:** Credit-based limits can be reached quickly on heavy research-agent usage; The advanced systematic review features and dual review sit behind the pricier team tiers; It is primarily English-oriented, which may suit non-English primary research less well; Newer compliance certifications such as SOC 2 and ISO 27001 are still listed as coming soon
