You start by preparing one: upload multiple PDFs or any text file from your device with the built-in upload manager, or simply provide a website link and let the service download and parse the content for you. Documents can be added or removed at any time, and indexing happens in the background so you are not left waiting. A usage tracker shows how much of your upload credit or subscription quota each file or site will consume before you commit. Once the dataset exists, you tune it. You pick a chat model and decide how much context, history and output space to allocate, adjust the temperature to control how creative or deterministic the answers are, and use system prompts to give the AI a name, a personality and a preferred language. Datasets can also be made public and shared by link, effectively turning your knowledge base into something other ChattyDocs users can query. The chat experience is built around traceability and continuity. Answers arrive with their sources attached — file name plus page number for multi-page documents, or a direct link for websites — and you can export every question and answer with one click. Sessions are persisted, so you can pick up a conversation where you left off, and you can attach a standing chat context that gets folded into every query alongside the dataset content. The same sessions are visible whether you use the web app, an embedded web source or the Telegram bot, and ChattyDocs is available on desktop, mobile and Telegram. **Pricing & Plans:** Free trial plus paid plans; the site links a pricing page and tracks consumption against an upload credit or subscription quota. - **Upload files or a website link:** Add multiple PDFs and text files from your device, or supply a URL and let ChattyDocs download and parse the content automatically. - **Model, context and creativity controls:** Choose the chat model, allocate context, history and output sizes, and set temperature to dial creativity up or down. - **System prompts for personality:** Instruct the AI on behaviour, tone and language through system prompts. - **Answers with cited sources:** Responses include the relevant sources, with document name and page number or a link to the crawled website. - **Persistent sessions across channels:** Continue conversations where you left off and preview sessions from the app, an embedded web source or Telegram. **Strengths:** Answers cite their sources with page numbers or links, making verification straightforward; Accepts both file uploads and website URLs, with background indexing; Granular control over model, context size, temperature and system prompts; Same persisted sessions across web app, embedded widget and Telegram **Limitations:** Multi-step setup: you need to build and configure a dataset before chatting; Usage is metered against an upload credit or subscription quota; Shared public datasets expose your knowledge base to other ChattyDocs users by design [Profile (Markdown)](https://openaitools.app/tool/chattydocs.md) ## PDF.ai PDF.ai is an AI document assistant that turns static PDFs into something you can talk to. You upload a file, then ask questions in natural language and receive answers grounded in the document, with citations pointing back to the relevant passages so you can check the source. This makes it practical for long reports, research papers, contracts, manuals and any dense document where you need a specific fact rather than a full read-through. Beyond Q&A, the platform handles common document chores. It can summarize long documents, extract specific fields or structured data, and help you locate details quickly across multiple files. Because answers include citations, it suits readers who need to verify what the AI says rather than trust it blindly. For teams that build their own tools, PDF.ai also ships a developer API. The API can parse documents, extract structured data and split PDFs, letting you embed document understanding directly into your own applications and pipelines. The combination of a polished chat interface for end users and an API for developers makes PDF.ai useful both as a standalone reading assistant and as a building block for document-heavy products. **Pricing & Plans:** PDF.ai uses a freemium model with a free trial. Free access is limited in how many documents and questions you can use each day, while paid subscriptions raise those limits and unlock heavier usage plus API access. Check the official pricing page for current tiers and rates. - **Chat with PDFs, with citations:** Ask questions in plain language and get answers drawn from your document, with citations back to the source passages. - **Summaries and instant answers:** Generate quick summaries and find specific answers in long reports, contracts and papers without reading every page. - **Data extraction:** Pull structured data and fields out of documents to reuse in spreadsheets, apps or other automations. - **Developer API for parsing and splitting:** Use the API to parse documents, extract data and split PDFs programmatically inside your own workflows. - **Multi-question document workflow:** Ask follow-up questions to dig deeper into a document, or jump between multiple uploaded PDFs in one workspace. **Strengths:** Chat with PDFs and get answers with source citations; Handles summarization, Q&A and data extraction in one tool; Developer API for parsing, extracting and splitting documents; Free tier and trial make it easy to evaluate **Limitations:** Free usage is limited in the number of documents and questions per day; Heavier workflows and API usage require a paid subscription; Answer quality still depends on the clarity and formatting of the source PDF; Scanned or image-only PDFs may need good OCR to be understood accurately [Profile (Markdown)](https://openaitools.app/tool/pdf-ai.md) ## Frequently Asked Questions ### How do ChattyDocs and PDF.ai compare in monthly traffic?
