## Lingpad

Lingpad is a platform built around two pillars: AI Translation and an AI Agent, with an AI Copilot in development. The company's roots are in multilingual customer support: support teams use Lingpad to translate inbound tickets, agent replies and help center content inside tools like Zendesk, Intercom, Gorgias and HubSpot, while keeping brand tone and terminology consistent through glossaries. A Chrome extension extends the same engine to everyday browsing, letting you translate any page, message or snippet you see online into more than 120 languages on the spot.

Lingpad markets itself on contextual quality rather than raw machine output. Its translation engine is designed to understand context and brand voice, and a Global Glossary keeps product names and terminology consistent across languages. Inside helpdesks, features such as two-way conversation translation, translation disclaimers for agent review, unlimited agent access and automated help center translation round out the workflow. The platform is ISO 27001 certified and GDPR compliant, and states that it does not store or train on your source or translated text.

Pricing separates a flat platform fee from usage-based AI credits. A $59/month platform tier gives an entire team access to AI Translation and the AI Agent, and a 7-day trial includes 10,000 free credits. Additional credits are sold on demand, with volume discounts and no expiration. The free Chrome extension is the low-friction entry point for individual users who want browser-level translation.

**Pricing & Plans:** Freemium entry point via the free Chrome extension. The core platform starts at $59/month including 10,000 free trial credits, plus pay-as-you-go AI credit packs with volume discounts and no per-seat fees.

- **Contextual AI translation:** Translates web content and support conversations with awareness of context and brand voice, rather than word-by-word output.
- **120+ language coverage:** The Chrome extension and platform support translation into more than 120 global languages.
- **Helpdesk integrations:** Works inside Zendesk, Intercom, Gorgias and HubSpot to translate tickets, chats and replies without leaving your workflow.
- **Global Glossary:** Keeps product names, tone and terminology consistent across every language your team supports.
- **Privacy-first design:** ISO 27001 certified and GDPR compliant; Lingpad states it does not store or train models on your source or translated text.

**Strengths:** Free Chrome extension makes it easy to try browser translation at no cost; Contextual engine with glossaries supports consistent brand terminology; Native integrations with Zendesk, Intercom, Gorgias and HubSpot; No per-seat pricing and a $59/month all-in-one platform tier

**Limitations:** Full helpdesk translation and AI Agent require the paid platform tier; AI credits are consumption-based, so heavy usage adds variable cost; The AI Copilot is still listed as coming soon; The Chrome extension has a small install base and few store reviews

## 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
