## Noiz

Noiz is built around a simple promise: skip the watching and still get the knowledge. Instead of copying a link into a separate tool and crafting a prompt, you install a browser extension, open a YouTube video, and click summarize. Noiz returns the key ideas as a clear list, optionally with timestamps that jump to the exact moment, plus a full video-to-text transcript when you need the words, not just the gist. It handles everything from a two-minute clip to a multi-hour course or podcast.

The product also ships mobile apps for iOS and Android, so the same summaries are available when you are away from your desk. Beneath the summarizer sits a wider library of free AI utilities covering transcripts, PDF and article summaries, text summarizers, content generators, and YouTube growth helpers like title, description, and tag generators. Summaries can be translated into more than 40 languages, and a weekly top-100 view helps you track what is trending on YouTube.

Noiz positions itself as a learning and productivity companion rather than a media downloader. The audience is students, researchers, and professionals who consume a lot of long-form video and want structured notes instead of raw playback time. It reports more than half a million users, with a free trial that leads into a paid subscription.

**Pricing & Plans:** Free trial, then paid subscription. You can test Noiz before subscribing; plans are purchased through the extension or mobile apps. Check the official site for the latest prices and tiers.

- **Key Ideas Extraction:** Get the essential points from any topic and length of video as a short list or a detailed breakdown, without watching the whole thing.
- **Timestamped Summaries:** Each summary point carries a timestamp that links back to the moment it came from, so you can verify or jump straight to the relevant section.
- **Video to Text Transcripts:** Convert YouTube audio into accurate, readable text that you can scan, quote, or use as notes for research and study.
- **41-Language Support:** Summarize and translate content across 41 languages, making international lectures, interviews, and creators accessible in your own language.
- **Browser Extension and Mobile Apps:** Summarize directly on YouTube from the extension, or on the go with the dedicated iOS and Android apps, so learning fits wherever you are.

**Strengths:** Summarizes on YouTube itself, with no tab switching or prompt writing; Timestamped summaries make it easy to verify and jump to source moments; Handles very long videos up to about 12 hours, including podcasts; Companion iOS and Android apps extend it beyond the desktop browser

## 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
