## ChatPDF

ChatPDF started as a simple "chat with your PDF" utility and has grown into a full research and study workspace. You can drop in a PDF, Word document, PowerPoint deck, Markdown or text file, paste a link, or point it at a YouTube video, then ask questions in natural language. Answers are grounded in your sources and come with clickable citations so you can verify anything straight from the original page.

Beyond one-off Q&A, the platform supports folders and multi-file chats, so you can query a whole reading list at once and compare findings across documents. A side-by-side layout keeps the conversation and the document open together, while translation lets you read material in another language or ask questions in a language different from the source. The team has expanded the suite with an AI writer, AI detector, flashcards, slide generation, and a dedicated research mode.

Access is browser-based and device-agnostic, with desktop and mobile apps available. The free tier covers a limited number of documents per day with no sign-up required for the core experience, while the paid Plus plan removes limits and unlocks advanced features. Enterprise-grade handling (SSL in transit, encrypted storage, SOC 2 Type II storage provider) is advertised, and users can delete their documents at any time.

**Pricing & Plans:** Freemium. A free tier lets you analyze a limited number of documents per day, and the core chat experience works without creating an account. ChatPDF Plus is a paid subscription that adds unlimited document analysis and advanced features — check the site for current plan details and regional pricing.

- **Cited answers:** Every response is anchored to your source document with clickable citations that scroll to the exact passage, so verification takes seconds instead of page-by-page searching.
- **Multi-file chat and folders:** Organize documents into folders and query many files in a single conversation to compare arguments, cross-reference findings, or study a whole syllabus at once.
- **Summarization and translation:** Condense long papers, reports, and contracts into key takeaways, and translate or query documents in any language — including mixing a source language with a different question language.
- **Study and writing tools:** Generate flashcards and slide decks from your material, and use the built-in AI writer and AI detector for drafting and checking academic text.
- **Side-by-side reading view:** Keep the chat panel and the PDF open together so answers stay linked to the original content while you read along.

**Strengths:** Answers include clickable citations tied to the original page, which makes fact-checking straightforward; Works with PDFs, Word, PowerPoint, Markdown, text, YouTube links, and web pages in one place; No account needed to try the core chat experience, and the free tier covers light daily use; Multilingual: upload in one language and ask questions in another

**Limitations:** The free plan caps how many documents you can analyze each day; Advanced features such as unlimited analysis and the full study toolkit sit behind the paid Plus subscription; Very large documents or heavy multi-file sessions can be slower and may hit size limits

## AIDojo

AIDojo takes the familiar chat-client formula and pushes it in two directions: voice and your own documents. On the voice side it accepts spoken input, converts it to text, and can read replies back aloud, which makes it useful for hands-free or travel scenarios where typing is inconvenient. On the document side it uses embeddings to index files you attach, so the assistant can draw on your library instead of only its general knowledge.

Beyond the chat surface, the app offers practical housekeeping tools: prompt management, chat history you can browse and organise, adjustable temperature for custom prompts, and per-conversation settings such as auto-focus, vibration feedback and battery protection. Plugins extend reach beyond static knowledge, and the interface can be themed and localised, so the app adapts to how you prefer to read and work.

AIDojo is a client, not a model — you bring your own AI service credentials, and the app's value is in how comfortably it puts chat, speech and document retrieval in one native Apple interface. It has a small but real user base on the App Store, and is distributed free with optional in-app purchases for the Pro tier.

**Pricing & Plans:** Free to download on the App Store with in-app purchases; a Pro tier unlocks additional capabilities. Exact tier pricing is shown in the App Store listing and varies by region.

- **Text and voice conversation:** Ask questions by typing or by speaking. Voice input is transcribed to text and replies can be read back aloud, which is handy when you are travelling or away from a keyboard.
- **Embedding-based knowledge base:** Attach PDFs, EPUBs and plain text files to build a searchable personal library the assistant can draw on, with the option to hide individual items from retrieval.
- **Prompt and conversation management:** Save reusable prompts, browse and organise conversation history, and tune parameters such as temperature for more precise or more creative answers.
- **Plugins for live data:** Optional plugins such as web page and video summarisation pull in current information so answers are not limited to whatever the model learned during training.
- **Personalisation and localisation:** Adjust fonts, themes, languages and per-conversation behaviours like auto-focus, scrolling and vibration feedback to suit how you like to chat.

**Strengths:** Native Apple-first design across iPhone, iPad and Mac from a single app; Combines chat, speech-to-text, text-to-speech and document embeddings in one place; Personal knowledge base supports PDF, EPUB and plain text files; Fine-grained conversation settings including temperature, themes and languages

**Limitations:** The rebrand from OpenChit to AIDojo can be confusing when looking for the app or support material; Some App Store reviewers report playback and plugin errors on the Pro tier; It is a client only, so you must supply and pay for your own AI model access
