## HackSEO

HackSEO is a browser extension with a deliberately blunt promise: it sifts through internet nonsense and translates it into something you can actually understand. Web pages are increasingly written for search engines, procurement departments or legal review rather than for readers, and the result is text that is long, padded and full of jargon. HackSEO applies AI to that text and hands back a clearer version.

The extension fits into normal browsing rather than replacing it. Instead of copying paragraphs into a separate chatbot, you invoke it on the page you are already reading and let it simplify, shorten or restate the content. That makes it practical for dense product documentation, marketing pages full of buzzwords, policy documents, news analysis and technical write-ups where the underlying facts are simple but the wording is not.

The listing is a small, single-developer extension — version 1.0.0 from April 2024 with a modest user base and no ratings so far — which is worth knowing before you depend on it. Its store page also discloses collection of personal, financial, communications, browsing and usage data, so reading the developer's privacy policy is a sensible first step if you plan to use it on sensitive pages.

**Pricing & Plans:** Listed as a freemium browser extension. The Chrome Web Store listing shows no price, so check the store page or developer for current costs.

- **Plain-language rewriting:** Rewrites dense articles, reports and product pages into shorter, plainer phrasing that is easier to grasp quickly.
- **Summarisation of long content:** Condenses long passages so you can judge whether the substance is worth reading in full before committing.
- **Jargon removal:** Turns corporate, legal and technical vocabulary into everyday words without needing a dictionary detour.
- **In-browser workflow:** Runs in the browser as a Chrome extension, so it works alongside your normal browsing rather than in a separate app.

**Strengths:** Straightforward, single-purpose tool with no learning curve; Runs inside Chrome, so simplified text stays in your reading context; Useful for jargon-heavy corporate, legal and technical pages; Lightweight extension at roughly 351KiB

**Limitations:** Very small user base and no ratings, so reliability signals are thin; Last updated April 2024, so the underlying AI may lag newer models; Listing discloses broad data handling, which warrants privacy review

## 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
