## 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

## Summatim

Summatim is a Chrome extension whose whole purpose is to stop you from spending hours on a YouTube video that may not contain what you are looking for. Once installed, it can analyze the content of a video and return a concise summary of its key points, so you can quickly gauge whether the material matches your interests before deciding to watch the whole thing.

The extension is deliberately small and focused. It is not a general-purpose page reader or a note-taking suite; it exists to add a summarization action on top of YouTube. That makes it a natural fit for people who use video as a primary source of information — students working through recorded lectures, professionals following long interviews or conference talks, and anyone who wants to preview a review or tutorial rather than sit through all of it.

Summatim presents itself on the Chrome Web Store as a follow-up to its original YouTube summarization concept, with the extension listed as "Featured" and rated 5.0 by its (currently modest) set of reviewers. Because the value of a summarizer depends heavily on how faithfully the summary represents the source, it is best used as a fast orientation tool: get the gist first, then watch the segments that actually matter to you.

**Pricing & Plans:** Freemium. The Chrome Web Store listing categorizes Summatim as freemium, with the core extension available to install and paid options offered through the listing.

- **YouTube video summaries:** Run the extension on any YouTube video and receive a short digest of its key points.
- **Save viewing time:** Check whether a long video contains what you need before committing to watching it all.
- **Lightweight browser extension:** Installs as a small, unobtrusive Chrome extension that adds a summarize action to YouTube.
- **Works on long-form content:** Useful for lectures, interviews, reviews and long-form talks where the important parts are buried in the middle.

**Strengths:** Purpose-built for YouTube videos; Very small extension footprint; Helps you decide fast whether a video is worth watching; Highly rated by its current reviewers

**Limitations:** Small installed base compared with mainstream summarizers; Latest listing update dates to April 2024, so newer YouTube layout changes may affect reliability
