## 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

## TabMagic - AI Tab Manager

TabMagic - AI Tab Manager is a free Chrome extension built to tame tab overload. It tackles the everyday problem of too many open tabs by giving you labelled groups and a saved-tabs shelf, then adds an AI layer on top so you spend less time reading and more time acting. It is distributed through the Chrome Web Store and installs like any other extension.

The AI side is deliberately bring-your-own-key. To summarize a page or chat with its content, you supply your own OpenAI or Google Gemini API key, and the extension routes requests through your account. That keeps the developer's side free and lets you choose the model tier you want, but it also means your AI costs come from your provider plan rather than a TabMagic subscription. The extension lists a simple set of core jobs: grouping tabs, saving and reopening favourites, summarizing a page into key points, and chatting with the page you are on.

The extension is currently marked Early Access Preview and is free while the developer gathers feedback, with a small but positive user base. Because AI features depend on your key and your chosen model, quality varies with the provider and plan you bring. If you mainly want tidier tabs with an optional AI summarizer you control, it is a low-commitment way to try that workflow.

**Pricing & Plans:** TabMagic is free. It is currently in Early Access Preview as the developer collects feedback, and there is no developer subscription. AI features use your own OpenAI or Google Gemini API key, so any AI usage cost is billed by your chosen provider.

- **Organize tabs into labelled groups:** Keep your tabs tidy by sorting them into custom, labelled groups so related pages stay together.
- **Save frequently used tabs:** Save the tabs and collections you use most and reopen them in a click for quick access.
- **Summarize tab content:** Get a concise key-points summary of any web page instead of reading the whole thing.
- **Chat with tab content:** Ask questions and interact directly with the content of your open tabs through an AI chat, using your own key.
- **Bring your own API key:** Plug in your own OpenAI or Google Gemini API key to power the summarization and chat features at your preferred model tier.

**Strengths:** Free to install and use, with no developer subscription; Combines practical tab grouping with an AI summarizer and chat; Bring-your-own-key design supports both OpenAI and Google Gemini; Simple, focused feature set that is quick to learn

**Limitations:** Requires your own OpenAI or Gemini API key for AI features, so usage cost depends on your provider plan; Still labelled Early Access with a small user base, so the feature set may change; AI summarization and chat are only as good as the page content and your chosen model
