## 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

## taggingBox

Most bookmarking tools capture a URL and leave the actual insight buried somewhere on the page. taggingBox instead works at the sentence level: you drag over the passage that matters, and the extension files that exact snippet into a box you define. Boxes act as lightweight projects, so research for one client, one report, or one idea can live together instead of accumulating in a single undifferentiated list. Searching later happens by tag rather than by remembering where you read something.

The tagging layer is what separates it from a plain clipper. taggingBox uses the GPT-4 API combined with its own algorithm to read the context of the saved passage and propose tags, which makes the difference between a messy archive and one that stays navigable as it grows. Because AI does the first pass, consistent tag naming is easier to maintain, and the extension supports both Korean and English source pages, which suits bilingual knowledge workers.

The developer states that browsing history and personal data are not collected. The extension is free to use, with team collaboration and advanced features offered through the taggingbox.im service, which the listing points to for organizations that need shared boxes.

**Pricing & Plans:** Free. The Chrome Web Store listing offers the extension at no cost and directs users to taggingbox.im for team collaboration and advanced features; those paid tiers are handled on that service rather than the listing.

- **Box-based archiving:** Drag any sentence from an article, blog, or document and it is saved instantly into the box you choose, keeping related material together.
- **GPT-4 tag recommendations:** The combined GPT-4 API and proprietary algorithm proposes tags matched to the context of each saved snippet.
- **Korean and English support:** The extension is built to work on both Korean and English web pages, so mixed-language research stays in one system.
- **Tag-driven retrieval:** Find saved material by tag instead of hunting through browser bookmarks or a long uncategorized list.
- **Privacy-conscious design:** The developer states that browsing history and personal data are not collected by the extension.

**Strengths:** Sentence-level clipping captures the actual insight rather than just a link; GPT-4-backed tag suggestions keep a growing archive searchable; Boxes map naturally onto projects, clients, or topics; Free extension with Korean and English page support

**Limitations:** Small user base relative to mainstream note-taking tools, so fewer community resources exist; Team collaboration and advanced features require the separate taggingbox.im service; Effectiveness depends on you adopting consistent tag and box naming habits
