## ireadfaster

ireadfaster is a small, single-purpose Chrome extension built to answer one question fast: what is this video actually about? Once installed, it adds two panels to the YouTube watch page — "Summary" and "Transcript". Pressing Generate in either panel sends the video's content off to an OpenAI-backed API and returns a condensed overview or the spoken text within seconds. The extension's defining detail is that the output is clickable: tapping any line in the summary or transcript jumps the YouTube player to the corresponding point in the video, which turns a summary into a navigation tool rather than just a wall of text.

The extension is published by the developer not.pizza, based in Chicago, and is listed on the Chrome Web Store at version 0.0.17 with a small but well-rated user base. It is offered free of charge. Because every generation costs the developer a few cents in API usage, the extension may ask you to sign in with a Google account before generating — a light anti-abuse measure rather than a paid tier. The developer's privacy disclosure states that data is not sold to third parties and is not used for unrelated purposes.

As a lightweight utility it is best suited to people who watch a lot of long-form video — lectures, interviews, conference talks, reviews — and want to triage content quickly or search inside a video without scrubbing. It is a browser extension, not a platform: there is no dashboard, no library of past summaries, and no mobile app. Install it from the Chrome Web Store and it appears on the YouTube UI; remove it and nothing is left behind.

**Pricing & Plans:** Free. The extension is published on the Chrome Web Store at no cost, and no paid tier is advertised on its listing. Each generation incurs a small API cost for the developer, which is why a Google sign-in may be requested to prevent abuse.

- **In-page summary panel:** Adds a Summary section beside any YouTube video so you can read the gist before committing to watching.
- **Full transcript on the YouTube UI:** Generates the spoken text of the video without leaving the watch page or opening a third-party site.
- **Click-to-seek output:** Click any line of the summary or transcript to jump the player to that exact moment in the video.
- **OpenAI-powered generation:** Summaries and transcripts are produced through an OpenAI-backed API rather than a fixed template.
- **Google sign-in anti-abuse gate:** A lightweight sign-in may be required before generating, to stop automated misuse of the paid API.

**Strengths:** Free to install and use, with no subscription mentioned on the listing; Summary and transcript appear inline on YouTube, so no tab switching; Click any line to seek to that moment in the video; Small, focused tool — rated 5.0 by early users and used by a modest active base

**Limitations:** Chrome only — no Firefox, Safari or Edge-specific build advertised; Last updated August 2024, so newer YouTube UI changes may affect the panels; Requires a Google sign-in before generating, which some users will not want to do; No archive or history of previously generated summaries

## 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
