## LipSurf

LipSurf installs as a Chrome extension and layers voice control over whatever page you are on. The dictation side uses Google's speech-to-text engine so you can write emails, documents, messages and spreadsheet entries by speaking, with automatic punctuation and far fewer typos than typing. The command side turns your voice into a navigation and control channel: open and switch tabs, follow links by number, scroll articles, play or pause video and jump around the interface without reaching for the mouse.

**Pricing & Plans:** LipSurf is freemium: the extension is free to add and use with usage limits, and paid subscription tiers unlock higher dictation limits and premium features. Pricing is listed on the official site. There is no hardware to buy — it works with your existing microphone.

- **Anywhere dictation:** Speak into any editable field on any site, powered by Google's speech-to-text engine, with a fast and accurate result and fewer typos.
- **Hands-free navigation:** Click links and buttons, scroll, move between tabs and control video playback with simple spoken commands.
- **Custom voice shortcuts:** Map any word or phrase to a page, action or text template so your own vocabulary and workflow work by voice.
- **Extensible plugin system:** Every feature is a plugin with open developer documentation, so developers can build deep integrations.
- **Multi-language support:** Recognises English, Spanish, French, Russian, Japanese and more, and you can add further languages.

**Strengths:** Dictation and navigation in one extension, across virtually every site; Built on Google's accurate speech-to-text engine; Custom shortcuts map your own jargon and frequent actions; Open plugin architecture with developer documentation

**Limitations:** Requires a Chromium-based browser such as Chrome; Voice control depends on a live internet connection for speech recognition; Some advanced dictation and premium features sit behind a subscription

## 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
