## 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

## YTchat

Watching a ninety-minute interview, lecture, or podcast just to find one answer is a poor trade. YTchat removes that trade by putting a chat interface directly beside the player. You open the YouTube video you care about, click the extension icon, and the chat appears next to the video. From there you can ask for the main takeaways, request specifics, or pull out a fact you half-remember, and receive quick responses grounded in the video's own content.

Because the assistant is scoped to the video's transcript, its answers stay on topic instead of drifting into general knowledge. You can also phrase your queries to steer the output — asking for a shorter answer, a bulleted format, or a focus on a particular detail. The interface is intentionally minimal, with a quick open-and-close flow so you can chat and get back to watching without a learning curve.

One important limitation: YTchat depends on the video having subtitles. It works best with videos that carry their own captions and can often handle auto-generated ones, but a video with no captions at all will not produce useful chat results. The extension was published in January 2024 and requests access to personally identifiable information and website content.

**Pricing & Plans:** Free to install from the Chrome Web Store. No subscription or paid tier is offered.

- **In-page AI chat:** Open a chat panel right next to the YouTube player without switching tabs or tools.
- **Video-scoped answers:** The assistant responds strictly within the context of the video you are watching, so answers stay relevant.
- **Ask for specific details:** Pull out a particular fact, quote, or section from a long video without hunting for the right timestamp.
- **Customizable responses:** Phrase your prompt to change the length or format of the reply, or to focus on the details you care about.
- **Minimal, fast interface:** A simple panel designed for instant open, quick question, instant close.

**Strengths:** Free with no account required; Answers stay grounded in the video you are watching; No need to jump between YouTube and a separate AI chat site; Simple interface with almost no setup

**Limitations:** Requires the video to have subtitles to work well; Only 22 users and no reviews, so track record is thin; Last updated in January 2024, so it may lag behind YouTube changes
