## 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

## Trans Frame

Trans Frame solves a very specific and very common annoyance: text that lives inside images, graphics, video frames or canvas-rendered UI, where ordinary copy-and-paste simply does not work. You activate the extension on a page, drag a frame around whatever you want to read, and Trans Frame captures that region as an image, applies AI text detection to recognise the characters, and returns a translation you can read immediately. Because the source is a screenshot rather than the page's DOM, the approach works equally well on infographics, scanned documents, photographed signs, embedded video subtitles and content bundled into third-party widgets.

The extension is lightweight in concept and free to install. It ships with no subscription, no account requirement and no data-collection disclosure beyond the developer's statement that user data is not sold or shared for unrelated purposes. The store listing shows a small but genuine user base and an update that keeps the extension compatible with current Chrome builds. It appeals most to language learners, travellers and cross-border knowledge workers who regularly hit the wall of unselectable foreign text.

If you already use a page-level translator, Trans Frame is complementary rather than a replacement: it covers the visual layer those tools usually miss. The main trade-off is that AI recognition on screenshots is only as good as the image quality it receives, so small, low-contrast or heavily stylised text can produce imperfect results. For clean, well-lit content it is a fast and frictionless way to break through a language barrier without leaving the page.

**Pricing & Plans:** Free to install and use. The Chrome Web Store listing shows no paid plans, subscriptions or in-app purchases; the developer states that collected data is not sold or shared for unrelated purposes.

- **Screenshot-based text capture:** Draw a frame over any area of a web page and capture it as an image, so text inside images, videos and canvas elements becomes readable.
- **AI text recognition:** AI text detection reads the characters in your captured region and turns the image into editable, translatable text.
- **Instant translation:** The recognised text is translated straight away so you can understand foreign-language content without leaving the page.
- **Works where copy-paste fails:** Because capture is visual rather than DOM-based, the extension handles infographics, scanned documents, subtitles and rendered widgets.
- **Free and account-free:** Install from the Chrome Web Store and start using it immediately with no sign-up, subscription or paywall.

**Strengths:** Free with no account or subscription required; Solves the problem of unselectable text inside images and video; Simple capture-a-frame interaction that requires no learning curve; Works alongside ordinary page-level translators rather than competing with them

**Limitations:** Recognition accuracy drops on small, blurry or stylised text; No offline mode, so results depend on an active connection; Full-page translation is not its purpose, which may surprise some users
