## Plae

Plae targets a very specific everyday annoyance: you are in the middle of a conversation, a chat or a support desk, and you suddenly need to say something in another language. Opening a browser tab, pasting text into a cloud translator and reading the result off your own screen breaks the flow and often exposes the message to a third party. Plae compresses all of that into one keyboard shortcut and a small pop-up window that lives in your Mac's menu bar.

Under the hood, Plae gives you three engines rather than one. Apple Translation is the default and uses the translation already built into macOS, giving native-quality output in 19 languages in under a second. Apple Intelligence takes over when you need better handling of slang, context and additional languages on supported hardware. And if your Mac has neither, Plae ships its own downloadable model powered by Google's TranslateGemma running via llama.cpp, offered in 4B, 12B and 27B variants for roughly 55 languages.

The privacy story is architectural rather than a policy promise. Translation happens on the machine, so there is no server farm receiving your text, no database of past translations, and no analytics or telemetry. For people typing sensitive material, such as medical or legal messages, that removes an entire category of concern.

Plae is built for daily use. History keeps the last 20 translations automatically and lets you star important ones, a single tap flips source and target languages so conversations flow both ways, and everything is reachable from the shortcut without hunting through menus. It is a one-time $4.99 purchase on the Mac App Store with a 7-day free trial, and it requires macOS Sequoia or later.

**Pricing & Plans:** $4.99 one-time purchase on the Mac App Store with all engines and future updates included; a free 7-day full-access trial is available, and there is no subscription or account.

- **Shortcut-first menu bar translation:** Trigger Plae with a global keyboard shortcut such as Cmd+Shift+T from any application, type your message and press Enter. No need to open a browser tab or switch apps to look up a phrase.
- **Full-screen presentation mode:** Turn any translation into a full-screen view with large type, so you can hand the screen to someone across a desk, a counter or a sofa and let them read it themselves.
- **Three on-device engines:** Choose Apple Translation for instant results in 19 languages, Apple Intelligence for better nuance on supported hardware, or Plae's bundled TranslateGemma model in 4B, 12B or 27B sizes for around 55 languages.
- **Privacy by architecture:** Translation, language packs and AI models all run on your Mac. No accounts, no analytics, no telemetry, and no text sent to a server, so private messages stay private.
- **Offline and account-free:** After the initial language pack or model download, Plae works with no internet connection, which makes it usable on flights, in remote areas, or on locked-down corporate machines.

**Strengths:** Very fast workflow: a global shortcut returns a translation from any app; Genuinely private, with translation, telemetry-free operation and no accounts; Full-screen presentation mode is perfect for in-person conversations; Works fully offline after a one-time language pack or model download

**Limitations:** macOS only, requiring macOS Sequoia or later; Apple Intelligence mode needs macOS Tahoe and an Apple Intelligence-capable Mac; Apple Translation covers 19 languages; the wider 55-language set depends on downloading a separate AI model; AI translation engines return results in a few seconds rather than instantly

## 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
