## Screenova

Screenova is a browser add-on built around one simple loop: grab it, read it, understand it. You take a screenshot of any part of a web page, and the extension uses optical character recognition to lift the text out of the image, then hands that text to an AI model that can explain concepts, produce a summary, or turn a messy block of text into a short list of action items. It is the kind of tool that quietly removes friction from research, studying, and inbox triage.

Because the extension lives in the browser toolbar, it works across almost any site — documentation, lecture slides pasted into a chat, a scanned receipt, a thread you want condensed. The listing advertises model selection among well-known chat models (ChatGPT 3.5 and 4 are named), so you can pick the level of reasoning you need for a question versus a quick gist. Everything runs from a single capture flow rather than a dashboard, which keeps the learning curve near zero.

The project is small and independently maintained, offered by the Screenova.app team, with a stated policy of not selling user data and limiting collection to website content. It has a modest install base and no rating history yet, so it is best treated as a handy utility rather than a heavy-duty enterprise tool. Version history is short, but the listing remains published and installable in the Chrome Web Store.

**Pricing & Plans:** Freemium. The extension installs free from the Chrome Web Store; the listing does not publish per-plan prices, and premium capability is generally tied to the AI provider you connect or to in-app upgrades. Check the extension's own page for the current terms.

- **One-click screenshot capture:** Highlight any region of a web page and capture it instantly from the browser toolbar, with no separate desktop app required.
- **OCR text extraction:** Optical character recognition pulls editable, copyable text out of screenshots, images, and captured page regions.
- **AI explanation and summarization:** Send extracted text to an AI model to get plain-language explanations, short summaries, or condensed key points.
- **Action-item generation:** Turn dense paragraphs — meeting notes, instructions, long posts — into a tidy checklist of next steps.
- **Model selection:** Choose between different tiers of chat models, from fast lightweight responses to more capable reasoning, depending on the task.

**Strengths:** Free to install and very fast to use — one click from the toolbar; OCR plus AI reasoning in a single flow instead of two tools; Works on any page you can view, including images and PDFs in the browser; Explicit privacy stance: data not sold to third parties, collection limited to website content

**Limitations:** Small user base and no ratings yet, so long-term support is unproven; Last published update dates to late 2024; feature velocity appears slow; AI quality depends on which model tier you select or connect

## 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
