The extension captures the relevant parts of your conversations and stores them in a memory layer that lives in the browser, so you can move from ChatGPT to Claude, or from Gemini to Mistral, without re-typing the same background information. The product is built around a dashboard where you can view, search, edit, add or delete individual memories. Memory can be applied manually with a button or a keyboard shortcut, or paused entirely for a session or a specific AI tool. Because memory is synced through Hiperyon's cloud, the same context is available across the devices you sign in on. Hiperyon is positioned around data ownership and privacy: the company states that your data belongs to you, that it is not sold to third parties, and that conversations and memories are encrypted in transit and at rest. The extension follows a freemium model, with a free basic tier and premium plans for advanced features. **Pricing & Plans:** Freemium. The basic Chrome extension is free, and premium plans unlock advanced memory features. Hiperyon says there are no hidden fees and no credit card required to start, and subscriptions can be cancelled at any time. - **Unified memory across models:** Context captured in one AI chat is instantly available in others, so you can switch between ChatGPT, Claude, Gemini, Mistral, Grok and more without repeating yourself. - **Memory dashboard:** View, search, edit, delete or manually add individual memories, and decide exactly what the assistant is allowed to remember. - **Manual memory control:** Trigger memory with the Ctrl+Q shortcut or a button when you want it applied, and disable memory per tool or pause capture entirely. - **Cloud sync:** Memories are stored on Hiperyon's servers so your context follows you across multiple signed-in devices. - **Privacy and GDPR posture:** Encrypted in transit (SSL/TLS) and at rest, with a stated policy of not selling or commercially exploiting your data. **Strengths:** Removes repetitive re-prompting when switching between AI chat tools; Granular, user-facing control over what is stored and when memory is applied; Cloud sync keeps context available across signed-in devices; Clear freemium entry point with a free basic tier **Limitations:** Requires a browser extension, so it only works where the extension is installed; Supported model list is still growing and may not cover every AI tool you use; Memory quality depends on Hiperyon's automatic relevance detection [Profile (Markdown)](https://openaitools.app/tool/hiperyon.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 Hiperyon and Sider compare in monthly traffic?
