Instead of copying a passage into a separate chatbot, you select it on the page and a small icon appears with an AI input field. Whatever you ask is answered inline, in the flow of reading, which keeps the source material and the conversation in the same visual context. The distinguishing design decision is that MARK•R does not restrict itself to the highlighted fragment. It reads the surrounding page as well, so questions can be about the wider argument, the definitions used elsewhere in the article, or the assumptions behind a claim. That makes it more useful for interpretation and analysis than a simple selected-text rewriter, and it is the reason the plugin is marketed for research, study and content development rather than only for editing. Practical applications cluster around comprehension and production. Students and researchers use it to unpack difficult concepts and terminology; professionals use it to clarify technical, legal or medical language; writers and marketers use it to generate summaries, outlines and alternative phrasing; and anyone drafting email in a browser can highlight the message they received and ask for suggested replies. Access is tiered: a free plan with a modest daily allowance of GPT-3.5 calls, paid Standard and Pro plans that add higher limits and GPT-4, and custom builds for organisations. The published plan structure references GPT-3.5 and GPT-4, so newer model options may not be available on this tool. **Pricing & Plans:** Freemium. A free tier provides 15 calls per day, 2,000 highlighted characters, 500 characters of prompt input, GPT-3.5 and 1,000 output characters. Standard is $8 per month and Pro is $12 per month, adding higher daily call limits, larger character allowances, longer output and GPT-4 access (one GPT-4 call equals 20 GPT-3.5 calls). Custom builds are available for organisations and enterprises. - **Highlight-to-ask interaction:** Selecting any passage on a page activates a dynamic icon and AI prompt field, so a question can be asked at the exact place you are reading rather than in a separate chat window. - **Whole-page context:** Responses draw on the surrounding article or page, not just the highlighted fragment, which supports deeper questions about argument, terminology and implications. - **Inline content generation:** Ask for an executive summary, a white-paper outline, slide talking points, suggested email replies or rewritten copy without leaving the browser. - **Comprehension support:** Explain difficult terms, unpack technical or legal jargon and request simpler phrasing, which helps with dense academic, medical and financial material. - **Tiered daily allowances:** Free, Standard and Pro plans set different daily call limits, character allowances, output lengths and model access, with custom enterprise builds available. **Strengths:** Works inline on any page, so you never have to copy text into another tool; Uses the whole page as context, not just the highlighted passage; Low entry price with a genuinely usable free tier and clear plan differences; Broad range of applications from study and research to summaries and email replies [Profile (Markdown)](https://openaitools.app/tool/mark-r.md) ## SEER SEER is a browser extension for people who constantly interrupt what they are doing to look something up. Rather than opening a new tab, reformulating a question in a search engine and sifting through results, you keep working in the current page and let the extension answer in context. The publisher's own description frames it as a way to navigate any platform and get the information you need right away. The extension is free, very small (around 394 KiB) and published by an individual developer. The Chrome Web Store listing carries version 0.0.1, updated in August 2024, and a small user base — in other words, it is an early build. The listing title itself references a Next.js Chrome extension starter template, which suggests the product is a working demonstration of an AI assistant concept rather than a mature, feature-complete platform. On privacy, the developer discloses that SEER handles user activity data and declares it is not sold to third parties, not used for unrelated purposes and not used for creditworthiness or lending decisions. Because the tool is at an early version and updated infrequently, treat it as a convenient experimental helper rather than something to depend on for critical workflows. **Pricing & Plans:** SEER is free to install and use; the Chrome Web Store listing shows no paid tier, subscription or in-app purchase. Its pricing model is listed as Free. - **In-page AI answers:** Ask for information while staying on the page you are working in, instead of switching tabs to a search engine. - **Platform navigation help:** The assistant is designed to help you find your way through a site or web app and locate what you need. - **Instant lookup rather than searching everywhere:** Consolidates a lookup that would otherwise mean checking several sources into one quick request. - **Very small footprint:** About 394 KiB in size, in English, running in Chrome without a heavy install. - **No account or payment required:** Install from the Chrome Web Store and use it without a subscription or billing details. **Strengths:** Free to install and use, with no subscription; Very small download size; Answers are delivered in the page, reducing tab switching; Clear privacy disclosure about user activity data **Limitations:** Early version (0.0.1, last updated August 2024) with a very small user base; No ratings on the Chrome Web Store listing; Published from a starter/demo template, so depth of features is limited; English-only interface [Profile (Markdown)](https://openaitools.app/tool/seer.md) ## Frequently Asked Questions ### How do MARK•R and SEER compare in monthly traffic?
