## InOtherWord - Translate Complex Docs

InOtherWord.AI is a document translation platform built specifically for real working files rather than pasted text. You upload a PDF, a scanned PDF, a DOCX, a PowerPoint deck or an EPUB book, pick the target language, and the service returns a translated version that keeps the original layout: tables stay tables, headings stay headings, images stay in place and multi-page structure is not flattened into a single block of text. That matters for contracts, patents, court filings, research papers, corporate reports, presentation decks and published books, all of which lose usable meaning when formatting is destroyed.

Under the hood the platform routes work through leading large language models — OpenAI, Google Gemini and Claude are named on the site — and layer OCR on top for scanned or image-based documents. Users can seed a custom glossary so specialised terminology, product names and legal phrases are handled consistently across a project. After translation, a built-in editor lets you post-edit the output and a preview lets you check pages before downloading, and the workflow supports batch processing so repeated files are not handled one at a time.

The service positions itself for professionals rather than casual use: law firms and legal consultants translating contracts and certificates, universities and researchers sharing papers internationally, companies translating reports and decks, publishers and media translating books and manuscripts, government and NGO teams working under data-protection rules, healthcare teams handling records, educators preparing materials for bilingual and ESL students, and religious organisations translating curriculum. The site advertises short turnaround times, GDPR and COPPA compliance, 256-bit encryption, confidential processing that is never used for model training, data deletion on request, and a money-back guarantee, and it exposes an API for teams that want translation embedded in their own workflow.

**Pricing & Plans:** Free to trial with a short preview upload and no sign-in required; larger files, batch jobs and API usage move to paid tiers. Check the pricing page for current per-page or subscription rates.

- **Layout-preserving translation:** Translates the file itself, not extracted text, so tables, headings, columns, images and page structure stay where they were in the source document.
- **Scanned document and OCR support:** Scanned PDFs and image-based files are recognised with OCR and translated without you having to retype or rebuild the page layout.
- **Wide format coverage:** PDF, PPTX, DOCX and EPUB are supported today, covering legal contracts, slide decks, reports, theses and full-length books.
- **Custom glossaries:** Define how key terms must be translated so terminology stays consistent across a long project, a client account or a whole catalogue.
- **In-browser post-editing and preview:** Review the translated output, make post-edits in the built-in editor and share or download the review-ready file without leaving the platform.

**Strengths:** Formatting, tables and images survive the translation, so output is usable without manual rebuilding; Handles scanned PDFs via OCR instead of requiring a digital text layer; Covers the formats professionals actually work in — PDF, DOCX, PPTX and EPUB — in one tool; Strong stated compliance posture: GDPR, COPPA, SOC 2, ISO 27001, encryption and no training on customer data

**Limitations:** Machine translation still needs review for high-stakes legal or medical wording, despite the post-editing tools; The free preview is limited, so evaluating quality on a full-length document requires a paid plan; Quality and turnaround depend on the underlying third-party models rather than proprietary technology

## 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
