## 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

## Speak

Speak is an AI-powered language learning app that focuses on spoken practice, pairing an expert-designed curriculum with an AI tutor that holds real conversations and gives instant feedback. Speak is an AI-powered language learning app built around speaking rather than studying. Its Speak Method loops through three stages — learn the phrases native speakers actually use, practice them until they become automatic, and apply them in real conversation with the AI Speak Tutor, which returns immediate feedback on your pronunciation and phrasing. The curriculum is created by language education experts and personalized by AI, with lessons matched to your level. AI conversation practice: The Speak Tutor holds a real back-and-forth conversation with you in the target language and gives feedback on what actually matters, as many times as you want. Real-time pronunciation feedback: Speak flags pronunciation and phrasing problems as you speak, so you can correct habits before they set in. Phrases-first curriculum: Every lesson is built around the phrases and patterns native speakers use in real situations, avoiding textbook sentences and grammar drills. Personalized lesson paths: The app adapts lesson order and content to your level and goals, with Premium Plus adding Made for You lessons and review built from your own mistakes. Learn on your own schedule: Lessons and tutor practice work on a phone, so a session fits into a commute or a coffee break rather than needing a scheduled class.

**Pricing & Plans:** Free trial plus subscription. Speak offers a 7-day free trial; afterwards a paid plan is required. Two tiers exist — Speak Premium for the core experience and Speak Premium Plus for unlimited personalized lessons, custom review from your mistakes, Made for You lessons and the full tutor experience. Prices vary by plan, region and promotion and are displayed in the app.
