## OpenL Translate

OpenL Translate is a browser-first translation workspace aimed at people who need more than a single text box. You can paste or type text, drop in an image or screenshot, upload a PDF, DOCX or subtitle file, or feed in speech, and the tool returns a translation in one of more than 100 languages. OCR handles scanned PDFs and photographed documents, while an image-to-image mode keeps the layout of posters and signs intact.

Quality controls are what set it apart from generic translators. Each request can run in general, professional, strict, technology, medical, finance, education or legal mode, and a Translate Agent is available for complicated passages where a plain sentence-by-sentence pass would lose nuance. Alongside translation, OpenL packages grammar correction, rewriting, summarization, an AI detector and a text-to-speech reader, so the same account covers drafting, proofreading and document conversion.

Pricing follows a freemium model with credits. Free users get daily credits, a 1,500-character limit and a handful of image and scanned-PDF translations. The Starter plan is around $8.9/month billed yearly, Pro around $9.9/month, and Ultimate around $29.9/month, each raising credit allowances, character limits (up to 150,000), file sizes and daily OCR quotas. Students and educators can request a 30% education discount with an .edu address, and payments run through Lemon Squeezy.

**Pricing & Plans:** Freemium with credits: free daily usage plus paid subscriptions. Starter is about $8.9/month and Pro about $9.9/month billed yearly (Pro is highlighted as 50% off), with Ultimate about $29.9/month. Students and teachers with an .edu email can request a 30% discount.

- **Multi-format translation:** Translate text, screenshots, images, PDFs, DOCX files, subtitles and audio in one workspace, with OCR for scanned documents and complex images.
- **Domain and tone modes:** Choose general, professional, strict, technology, medical, finance, education or legal modes, and enable the Translate Agent for harder content.
- **Grammar, rewrite and summarize:** Writing aids include grammar correction, rewriting suggestions, summarization and supporting tools for language learners.
- **In-browser translation:** Browser extensions for Chrome and Microsoft Edge, plus a side panel for longer text, let you translate any page or selection in place.
- **AI detector and OCR:** An AI detector, Pro OCR for difficult images and an accessible translation API extend OpenL beyond plain translation.

**Strengths:** Wide input coverage: text, images, scanned PDFs, DOCX, subtitles, speech and web pages in one place; Specialized modes for legal, medical, finance and technical content improve terminology accuracy; Free tier usable without login, and browser extensions make in-page translation convenient; Extra tools like grammar checking, summarization, AI detection and OCR come bundled rather than costing extra

**Limitations:** Credits are consumed quickly on long documents or heavy OCR use, and limits differ by plan; Advanced credits and Pro OCR are reserved for the Pro and Ultimate tiers; Free plan's 1,500-character ceiling and low daily image quota can feel restrictive for professional work

## 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
