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) ## Yoptio Information overload is the defining problem of following the news. Yoptio approaches it the way a careful reader would: it does not try to replace your sources with an algorithm, it simply takes the RSS feeds you already trust and makes them manageable. Everything lands in one chronological stream, so you decide what matters rather than a black-box ranking. The AI layer is there to shorten the distance between headline and understanding. Each article can be condensed into a summary, read aloud, or folded into a daily briefing that surfaces the day's essentials. Keyword muting adds a defensive filter: if a word or phrase reliably ruins your day — a spoiler, a rage-bait hook, an ad term — you can hide it entirely. In practice Yoptio targets people who read a lot on purpose: researchers, journalists, developers, analysts and anyone who has quietly accumulated dozens of feeds. It is a focused, subscription-style reader rather than a social network, and it is positioned as a free tool, so it is easy to try against your existing reading routine. **Pricing & Plans:** Yoptio is presented as a free AI-powered RSS reader. No dedicated pricing page is published, so confirm current plan details and any limits on the site. - **Unified chronological feed:** Bring the RSS feeds you already follow into one clean, time-ordered stream instead of hopping between apps and tabs. - **AI article summaries:** Every article gets a concise AI-generated summary so you can judge whether it is worth the full read. - **Audio playback:** Have articles read aloud so you can catch up while commuting, cooking or working out. - **Daily AI news briefing:** A daily AI-curated digest rounds up the most relevant items from your sources in one short briefing. - **Keyword muting:** Mute chosen keywords to hide spoilers, ragebait, ads and any other topics you would rather skip. **Strengths:** Turns a messy pile of feeds into one tidy chronological timeline; AI summaries and audio playback cut reading time significantly; Keyword muting is a genuinely useful defence against spoilers and ragebait; Simple, reader-first design with no algorithmic agenda **Limitations:** The interface is deliberately minimal, so anyone expecting a social or algorithmic discovery layer will find it plain; You supply your own feeds — there is no built-in feed directory or recommendation engine; Some newer capabilities depend on signing in, and pricing details are not spelled out on a dedicated page [Profile (Markdown)](https://openaitools.app/tool/yoptio.md) ## Frequently Asked Questions ### How do Sider and Yoptio compare in monthly traffic?
