## ReadPilot

ReadPilot positions itself against the familiar problem of the endless reading list: pages you mean to read but never get to. Rather than saving articles for a 'later' that rarely arrives, ReadPilot summarises the content you are already looking at, presenting a digest directly on the webpage so you can decide what deserves your full attention.

The extension works on both text and video. For long articles and webpages it produces a concise summary; for video content it extracts the key points so you can grasp the substance without watching the whole thing. You are not stuck with a single style of output either — you can adjust the length, tone and perspective of a summary, and choose the language it comes back in, which is handy if you read across several languages.

ReadPilot also keeps what you generate: summaries are stored together with their original links, giving you a lightweight knowledge base to return to. The developer, EverGrow Tech Inc., lists upcoming features such as sharing summaries, asking questions about the underlying content, and support for more AI models and languages, signalling that the tool is meant to grow beyond simple summarisation.

**Pricing & Plans:** ReadPilot is freemium. The Chrome Web Store listing notes that it offers in-app purchases, so core summarising is available to try, with additional capacity or features unlocked through a paid upgrade. Specific prices are shown inside the app and may change over time.

- **One-click text and video summaries:** Read any webpage or video and get a concise summary in under a minute, right on the page you are viewing.
- **Customisable prompt:** Set the length, tone and perspective of a summary so the output matches whether you want a quick gist or a structured brief.
- **Multi-language output:** Receive summaries in your preferred language, useful when you read across languages or want consistent output.
- **Knowledge management:** Save summaries alongside their original links so reviewed material becomes searchable, reusable knowledge rather than scattered tabs.
- **Sharing, Q&A and more models (upcoming):** Planned additions include sharing summaries with friends or social media, asking questions about the original content, and support for more AI models and languages.

**Strengths:** Summarises both webpages and videos from one extension; Adjustable length, tone and perspective for each summary; Multi-language output suits readers working across languages; Saves summaries with their source links as a reusable knowledge base

**Limitations:** Small user base compared with some summarizer extensions; Some listed features, such as sharing and Q&A on content, are marked as upcoming; Offers in-app purchases, so advanced capacity may cost extra; Listing was last updated in 2024, so feature velocity is unclear

## 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
