## 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

## ChatDOC

ChatDOC turns long documents into something you can question. Instead of scrolling through hundreds of pages, you upload files and chat with them: ask for a summary, request an explanation of a clause, or have the tool pull specific data points out of dense tables. Unlimited pages and files can be processed on paid plans, and the assistant handles formats including PDF, DOC, DOCX, scanned images, web pages, EPUB, Markdown and plain text.

A key part of the experience is verifiability. ChatDOC highlights the passages behind each answer, so you can click through to quotes, cross-page tables, formulas and images rather than trusting an opaque response. It also speaks more than 25 languages, supports OCR for scanned documents, recognises formulas, and can translate whole files while preserving the original layout.

Beyond the main chat product, ChatDOC offers ChatPaper for conversational reading of academic papers and a separate PDF Parser API for developers who need structured extraction inside their own applications. A Chrome and Edge extension keeps the assistant available while browsing. A free tier with daily question and page limits lets you evaluate it before committing to the annual Pro plan.

**Pricing & Plans:** Freemium. A free plan offers limited daily questions and total question caps with small file-size and page limits; the Pro plan is billed in 30-day or 360-day terms and unlocks unlimited questions, pages and larger files. Image analysis is a paid add-on.

- **TapSource answer tracing:** Every answer highlights the source passages, tables and images behind it so claims can be verified in one click.
- **Wide format and OCR support:** Handles PDF, DOC, DOCX, scanned files, websites, EPUB, Markdown and TXT, with OCR and cross-page table recognition.
- **Multi-language translation:** Chat in 25+ languages and translate entire documents while keeping the original layout intact.
- **ChatPaper and PDF Parser API:** Use ChatPaper for academic papers, or integrate the PDF Parser API to extract structured content into your own product.
- **Prompt library and visual outputs:** Save reusable prompts and turn findings into infographics to share results with a team.

**Strengths:** Answers link back to highlighted sources instead of being opaque; Handles scans, formulas and cross-page tables that basic PDF chat tools miss; Free tier with no card required makes evaluation easy; Separate API and ChatPaper options cover developer and academic needs

**Limitations:** Free plan caps daily questions, total questions and file size; Image analysis is a paid add-on rather than included; Best value requires committing to an annual Pro plan
