## 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

## TransGull

TransGull is an AI translation tool designed for 'every cross-language moment' — travel, study abroad, international work, language learning and following favourite creators. Its headline claim is translation you can trust: rather than producing literal output, it aims for context-aware, natural phrasing that reflects how people actually speak. According to the official site it supports 47 languages and is chosen by more than 450,000 users worldwide.

The product goes well beyond text boxes. TransGull offers conversation translation for face-to-face chat, simultaneous interpretation for lectures and meetings, live speech translation that can be heard through earphones so you do not have to stare at the screen, video translation for YouTube and local files, image translation for menus and signs, online meeting translation for Zoom, Teams and Google Meet, live-stream captions, phone call interpretation and document translation.

TransGull is available as dedicated apps for Windows, Mac, iOS and Android. Reviews repeatedly highlight the quality of phrasing, the usefulness of bilingual subtitles for language learning, and the responsiveness of support. Instead of a rigid monthly subscription the service uses a credit system called 'Shells', so users pay for the volume they actually consume. A TransGull for Business offering adds member management, permissions, usage controls and a commitment that translation content is never used to train AI models.

**Pricing & Plans:** TransGull does not advertise a conventional subscription-first model. Reviews and its own marketing describe a credit-based system where usage is measured in units called "Shells", intended so customers pay only for what they use. A separate TransGull for Business plan exists for teams and organisations; specific price points should be confirmed directly with the vendor.

- **All-in-one translation across 47 languages:** The core engine handles conversation, speech, image, video and document translation across 47 languages, with context-aware phrasing that sounds natural.
- **Simultaneous interpretation:** Follow lectures, tours and meetings with live speech translation that can be read on screen or heard through earphones as audio output.
- **Video and live-stream translation:** Translate YouTube and local videos in one click and follow foreign-language live streams with real-time bilingual captions.
- **Image and document translation:** Point at menus, signs and vertical text to get accurate image translation, and convert documents from one language to another.
- **Meeting and call interpretation:** Understand all major meeting platforms including Zoom, Teams and Google Meet, with phone call interpretation for remote conversations.

**Strengths:** Covers conversations, speech, video, live streams, images, documents and phone calls in one app; 47 languages with context-aware, naturally phrased output; Audio translation through earphones is genuinely useful for lectures and travel; Available on Windows, Mac, iOS and Android

**Limitations:** No free tier is clearly advertised; the credits-based "Shells" model means you pay as you go; Best experience relies on installing desktop or mobile apps rather than pure browser use; Heaviest features like large events or enterprise meeting translation are aimed at business buyers; Translation quality still depends on audio clarity in noisy environments
