You can upload PDFs, slide decks, notebooks, EPUBs and other formats, then ask natural-language questions and pull out summaries, key points and exact quotes. Multi-document chat lets you compare several files at once, so contracts, research papers and reports can be interrogated side by side instead of read end to end. Two newer capabilities anchor the current product. The AI Agent builds a chatbot trained on your approved website pages and documents, which you can embed on most sites and frameworks to answer visitor questions around the clock and cut repetitive support tickets. The AI Form Filler reads a fillable or flat PDF form, takes data from another document, a text file or pasted text, and maps the right values into the right fields, which is aimed at onboarding forms, applications, intake documents and recurring filings. Around those core tools sit a document library, instant summaries, shareable conversations, tuneable assistants, a document widget and more than 40 free utilities for writing, editing and content creation. AskYourPDF states that it is GDPR compliant and applies encryption and access controls to the content you train on and the conversations your agents handle, and it reports more than five million users worldwide. **Pricing & Plans:** Freemium. A free tier and a large set of no-signup free tools are available, with paid plans and API access for heavier chatbot, form-filler and document-chat usage; enterprise pricing is available on request. - **Chat with documents:** Ask plain-language questions across one or many PDFs, decks, notebooks and e-books, and get summaries plus pinpoint quotes. - **AI website chatbot agent:** Train a support agent on approved website and document content, embed it on most sites, and let visitors open support tickets when the bot cannot answer. - **AI PDF form filler:** Auto-complete fillable or non-fillable PDF forms by pulling values from another PDF, a text file or pasted text. - **Summaries, translation and extraction:** Condense long documents, translate them, extract structured content and generate podcasts or literature reviews. - **40+ free AI tools:** A no-signup suite covering writing, editing, captions, essays, splitting and merging PDFs and more. **Strengths:** Handles both a single PDF and multi-document conversations in one interface; Combines chat, form filling and an embeddable chatbot rather than one narrow feature; Large library of free tools that require no signup; Explicit GDPR and encryption messaging for sensitive content **Limitations:** Free tier limits are tight enough that regular users will likely need a paid plan; Feature sprawl across agent, form filler and dozens of utilities can be hard to navigate; No public sticker pricing for the heavier plans, so costs require a sales conversation [Profile (Markdown)](https://openaitools.app/tool/askyourpdf.md) ## Sider Sider's premise is that you should not have to leave the page you are reading to use an AI assistant. Its sidebar overlays the browser, detects the content in view, and responds with chat, summaries, translations or explanations using frontier models from multiple providers. The result is a lightweight research and reading workflow: highlight a paragraph, ask for a simpler explanation, translate a PDF and keep the original in sight. Recent versions push Sider beyond chat. Sider Hand is a browser agent that works across real websites and uses your logged-in sessions to carry out multi-step jobs such as comparing prices while shopping, filling forms, doing cross-site research or triaging a Gmail inbox. Sider Code goes the other way, letting you instruct changes to a website's appearance or behaviour in plain language and preserving the customisation for next time. A Create module generates images, videos, slides and documents from the same panel. Pricing moves from a limited free tier to credit-based paid plans aimed at heavier users. Lower plans suit occasional chat, summarisation and translation, while higher tiers add a dedicated cloud computer that keeps the browser agent running around the clock and a larger monthly credit allowance. Sider ships as browser extensions for Chrome and Edge plus desktop and mobile apps for macOS, Windows, iOS and Android, and is used by a very large installed base. **Pricing & Plans:** Freemium. Free tier available with limited credits; paid plans advertised at roughly US$10/month for occasional use up to around US$100/month at the top tier, with higher credit allowances and a dedicated cloud computer on the upper plans. - **AI sidebar on any page:** A persistent panel that reads the page you are on and answers follow-ups with GPT, Claude or Gemini without copying content into another tab. - **Summarise and chat with documents:** Summarise long articles, PDFs and YouTube videos, extract key points, and ask detailed questions about the source material. - **Translation and read-aloud:** Translate webpages, PDFs and images, compare bilingual output side by side, and have content read aloud for review on the move. - **Sider Hand browser agent:** Delegate multi-step tasks across real websites — price comparison, form filling, research and inbox triage — using your existing logged-in sessions. - **Sider Code page customisation:** Describe a change in plain words and have Sider restyle or simplify any website, remembering the modification for future visits. **Strengths:** Works inside the browser you already use, with no context switching; Access to multiple frontier models from one subscription; Strong reading toolkit: PDF chat, YouTube summaries, translation and read-aloud; Increasingly capable agent features for multi-step browser tasks **Limitations:** Useful credits run out quickly on the free and lower tiers; Model availability and quota rules change over time, so expectations must be checked per plan; Some agent and code features depend on a cloud machine and heavier plans [Profile (Markdown)](https://openaitools.app/tool/sider.md) ## Frequently Asked Questions ### How do AskYourPDF and Sider compare in monthly traffic?
