## DocTranslator

DocTranslator targets a problem general-purpose translators handle poorly: documents with structure. Instead of pasting text and losing tables, headings and page breaks, you upload the file and the service returns a translated document that keeps the original layout. It supports a long list of source formats spanning Word, Excel, PowerPoint, InDesign, EPUB, HTML, CSV, JSON and image-based scans, with a dedicated PDF pipeline for large files that exceed the page limits of free translators.

The workflow is deliberately simple: sign up with an email, upload the document, choose the language pair from 108 supported languages, and download the result from your dashboard. OCR extends this to photographed or scanned pages, which is useful for contracts, certificates and archival material. Around the core translator, the site also offers auxiliary tools such as an AI PDF summarizer, word counters for DOCX/XLSX/PPTX/InDesign files, and format converters like PDF to DOCX.

Pricing is per document on the free tier, with word-based billing and a low per-document minimum, while subscriptions add monthly AI translation allowance, larger upload limits, longer document storage, OCR and priority support. For documents that legally require certification, the site points users to human professional translation as a separate service rather than claiming automated output is certified.

**Pricing & Plans:** Freemium with pay-as-you-go and subscription options. Signing up is free, then AI translation costs roughly $0.005 per word with a minimum per document, and PDFs or scans are billed per page. Paid subscriptions come with weekly, monthly or yearly billing and include OCR, larger files, longer storage and priority support.

- **Layout-preserving translation:** Tables, headings, images and page breaks stay in place, so the translated file is usable without reformatting.
- **108 language pairs:** Translate in either direction across 108 languages, from major European and Asian languages to less common ones.
- **Wide format and OCR support:** Handles DOCX, PDF, XLSX, PPTX, IDML, TXT, CSV, JSON, HTML, EPUB and image scans with optical character recognition.
- **Large-file PDF pipeline:** Dedicated handling for PDFs and scans that exceed the page and size limits of free online translators.
- **Auxiliary document tools:** Built-in PDF summarizer, word counters, and converters such as PDF to DOCX alongside the core translator.

**Strengths:** Original formatting is preserved, which saves significant reformatting time; Very broad format support including InDesign, EPUB and scanned images with OCR; Transparent per-word pricing on the free tier with a low minimum per document; Handles large PDFs that free translation tools reject

**Limitations:** Automated output is not a certified translation, so legal use still needs a human translator; Working on the free tier is really a sign-up flow rather than an instant drag-and-drop translation; Free-tier files are small and stored briefly, which limits comparison testing

## 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
