Instead of starting with a blank prompt, you feed it something: a web article you want condensed, a PDF you need to understand, or a research trail you are building. Aili summarizes the material, then lets you ask questions about it in a chat thread so you can drill into the parts that matter. The assistant is model-agnostic by design and has been associated with several engines, including GPT-4, Claude 2 and Llama-2-70b. That flexibility matters for research work, where you may want one model for careful reasoning over a long document and another for quick triage of a stack of links. Aili also collects rather than only consumes. Browser extensions and cross-platform apps let you send pages and notes into the assistant from wherever you are working, so your summaries, questions and saved sources accumulate in a single workspace instead of scattering across bookmarks and note apps. It is aimed at students, analysts, writers and anyone whose job involves getting through a lot of reading quickly and retaining the useful parts. **Pricing & Plans:** Aili is offered on a freemium model, with a free tier and paid upgrades. The live pricing detail could not be retrieved during this review, so check the current plan limits and upgrade costs directly on the Aili website or in the app. - **Web and document summarization:** Condense long articles, pages and documents into short, readable summaries so you can triage reading material quickly. - **Chat with your sources:** Ask follow-up questions about a summary or a document and get answers grounded in the material you supplied. - **Multiple model choices:** Works across named engines including GPT-4, Claude 2 and Llama-2-70b, so you can match the model to the task. - **Cross-platform access:** Browser extension and desktop or mobile apps let you capture and query content from wherever you work. - **Web collection workspace:** Saved pages, notes and summaries accumulate in one place, turning scattered reading into an organized research set. **Strengths:** Summarization-first design makes it genuinely useful for heavy reading workloads; Support for several models, including open-source options; Cross-platform capture keeps research from fragmenting across tools; Combines summarization, chat and collection instead of requiring separate apps **Limitations:** The official site was unreachable during this review, so current limits and features could not be independently confirmed; Summary quality depends heavily on the underlying model you select; Overlaps with general-purpose chatbots that also accept uploaded documents [Profile (Markdown)](https://openaitools.app/tool/aili.md) ## 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 [Profile (Markdown)](https://openaitools.app/tool/chatdoc.md) ## Frequently Asked Questions ### How do Aili and ChatDOC compare in monthly traffic?
