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) ## Simagizer Simagizer is a lightweight Chrome extension aimed at people who read a lot online and want a faster way to capture the essentials. Highlight or load a page, and it produces a condensed summary of the text, saving you from scrolling through long articles or reports. The distinctive part is what it does with that summary: Simagizer turns the text into a visual, image-style card that you can share on social media or download for later reference. That makes it useful for turning a lengthy article into a single glanceable graphic. Later versions extend beyond text, adding audio features that transcribe and translate spoken content using OpenAI-powered APIs. The extension is free to add from the Chrome Web Store, and pricing for any premium features is not published on the listing. **Pricing & Plans:** The extension is listed as free in the Chrome Web Store. No official price list for premium tiers is published on the listing page; any API usage depends on the OpenAI account you connect. - **Web content summarization:** Condense long articles, documents, and pages into short, readable summaries. - **Summary-to-image generation:** Turn each summary into a visual card you can download or share on social media. - **Audio transcription and translation:** Transcribe and translate audio content using OpenAI-powered APIs. - **Browser-based workflow:** Works directly as a Chrome extension without leaving the page you are reading. **Strengths:** Combines summarization and image output in one extension; Free to install from the Chrome Web Store; Adds audio transcription and translation **Limitations:** Requires your own OpenAI API access for AI features; Small user base and few ratings; Chrome-only, so other browsers need alternatives [Profile (Markdown)](https://openaitools.app/tool/simagizer.md) ## Frequently Asked Questions ### How do Sider and Simagizer compare in monthly traffic?
