## 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

## SummaryGPT

SummaryGPT is a Chrome extension for people who consume a lot of text online. Open any article, blog post, or long web page, click the extension, and it returns a condensed summary or a list of key bullet points within seconds, so you can decide what deserves your full attention.

Beyond summarizing, it offers a chat-style side panel. You can ask questions about the page, request a specific format, or drill into a section you care about, and the assistant keeps the page content as context. Prompts are customizable, so the output can be tuned to the shape you prefer, whether that means short bullets, a paragraph, or a specific extraction.

The tool targets students, researchers, and busy professionals who skim news, papers, and documentation daily. It is a lightweight extension, and a paid tier at summarygptai.com unlocks unlimited usage and enhanced features if the free allowance is not enough.

**Pricing & Plans:** Freemium. The extension can be used for free for standard summarization, and a Premium plan sold at summarygptai.com for $4.99 per month adds unlimited usage and enhanced features.

- **Instant summaries:** Generate a concise summary or list of key points from any article or web page in a few clicks.
- **Interactive chat:** Ask follow-up questions about the page and refine your queries through a clean chat interface.
- **Customizable prompts:** Adjust prompts so summaries focus on the specific facts, angles, or formats you care about.
- **Dynamic side panel:** A resizable side panel keeps the summary next to the original text so you can read and reference at once.
- **Multitasking friendly:** Works alongside your normal browsing without forcing you into separate tools or tabs.

**Strengths:** Fast summaries and key-point extraction directly on the page you are reading; Chat interface lets you ask targeted questions about page content; Customizable prompts make output adaptable to different needs; Resizable side panel supports reading and summarizing at the same time

**Limitations:** User base is small, so fewer public reviews and community tips are available; Summaries and chat depend on AI providers, which may require an account or API key; Core value is limited to in-browser reading workflows rather than standalone research
