## Eightify

Eightify is built for people who watch or skim a lot of long-form video and want to know what matters before committing an hour. Install the extension, open any YouTube video and the summarizer returns the key ideas directly alongside the player. Because the insights are timestamped, you can jump straight to the topic that interests you instead of scrubbing through the timeline. The same summaries are available on the web and through the iOS and Android apps, so a saved video can be caught up with on mobile.

Beyond bullet points, Eightify generates transcriptions that often beat YouTube's own subtitles, lets you skim the top comments to gauge whether an audience found the video useful, and produces summaries and translations in more than 40 languages. One-click sharing turns a finished summary into a readable article you can send to a colleague or classmate, which is why it is popular with students, educators, journalists, analysts and busy professionals who need the gist of a lecture, podcast or hearing.

The product is freemium: there is a free entry point and paid subscriptions for heavier use, and it has been used by hundreds of thousands of people worldwide. It works on virtually any YouTube video, including long committee hearings, multi-hour interviews and your own uploads.

**Pricing & Plans:** Freemium, with a free tier to try the summarizer and paid subscription options for regular, heavy use. Exact prices depend on the current plan menu shown at checkout.

- **Timestamped key insights:** Get the main ideas of a video with timestamps so you can jump directly to the topic you care about.
- **High-quality transcripts:** Access transcriptions that users report are cleaner and more accurate than YouTube's built-in subtitles.
- **Top comment overview:** Skim a digest of the top comments to see whether viewers like you found the video useful.
- **40+ language support:** Generate summaries and translations in more than 40 languages for global content.
- **Shareable summary articles:** Turn a finished summary into a readable article and share it in one click with colleagues or classmates.

**Strengths:** Works inline on YouTube as an extension plus web and mobile apps; Timestamped summaries let you navigate straight to the relevant section; Transcript quality and top-comment digest add context beyond bullet points; Summaries and translations in 40+ languages

**Limitations:** The most intensive usage sits behind a paid subscription; Requires an extra extension install for the smoothest YouTube experience; Summary quality still varies with audio clarity and video type

## 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
