## 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

## Transmonkey

Transmonkey is a web-based AI translation suite built around large language models. The platform leans on ChatGPT, Gemini and Claude for text understanding and uses OpenAI's Whisper and text-to-speech models to handle spoken content, which lets it move beyond word-for-word machine translation toward context-aware output.

The toolset is organized around the content type a user brings in: a document translator for office files, an image translator for graphics and screenshots, a video translator that combines transcription with subtitling and dubbing, a text translator for quick passages, and dedicated transcription and subtitle tools. Because the same engine powers each surface, users can move a project from raw footage to a finished, translated file without switching services.

Transmonkey positions itself for individuals and teams that need multilingual output but do not want to manage a manual localization pipeline. Chrome, Google Workspace and YouTube extensions let users work inside existing apps, while a standalone web app supports bulk uploads and instant downloads. This makes the platform useful for marketing localization, education, support content and creator workflows where speed and format flexibility matter as much as accuracy.

**Pricing & Plans:** Paid with a credit-based pay-as-you-go option (from $6 for 50 credits up to $99 for 4,000 credits) and Pro subscriptions at $12/month or about $8.3/month billed yearly. One credit equals one minute of video, one image, or 500 document characters.

- **Layout-preserving document translation:** Translate PDF, Word, Excel, PowerPoint, PNG, JPEG, MP4 and more than 30 other formats while keeping the original layout, with support for files up to about 1.5 million characters.
- **One-click image translation:** Upload an image up to 10MB, and the tool strips the original text and replaces it with the translation while preserving the background, with bulk download available.
- **Video translation and dubbing:** Transcribe, translate and dub videos in over 130 languages in a single pass, keeping background music intact and offering preset voiceover options.
- **Real-time text translation:** Translate up to 7,000 characters instantly in a web-based text translator with context-aware output across 130+ languages.
- **Browser and workspace extensions:** Translate directly from Google Chrome, Google Workspace and YouTube through official extensions that avoid copying and pasting between apps.

**Strengths:** Handles documents, images, video, audio and text in one platform; Preserves original document layout and image backgrounds; Support for 130+ languages backed by modern LLMs; Browser, Workspace and YouTube extensions for in-app use
