## Chat2GPT

Chat2GPT is a lightweight Chrome extension built around one clear idea: you should be able to talk to ChatGPT instead of typing at it. The extension listens to your voice, transcribes it into the ChatGPT input box and submits the message automatically; when the answer arrives, it is read aloud. The result feels closer to a spoken conversation than to a chat window.

On top of that core loop it adds a handful of workflow features. You can save prompts and insert them with a click, use prompt injection to append extra context to a saved prompt before it is sent, let ChatGPT display related images inline, or pick a text file and push its contents straight into the chat. An auto-prompt mode fires a queue of prompts one after another, waiting for each answer before sending the next, which is handy for batch tasks you would otherwise repeat by hand.

It is a small, developer-run project published in 2023 with a deliberately narrow scope. If your main frustration with ChatGPT is the keyboard, this removes it; if you want a full AI productivity suite, look elsewhere.

**Pricing & Plans:** The extension is listed as a free Chrome add-on with no subscription tiers shown on its store page. You still need your own access to ChatGPT to use it.

- **Voice input that submits itself:** Speak your question and the extension transcribes it into ChatGPT and sends it, no typing or Enter key required.
- **Spoken answers:** ChatGPT's response is read back out loud so you can listen while doing something else.
- **Saved prompts and prompt injection:** Store reusable prompts and inject extra context into them before they are submitted automatically.
- **Auto-prompt queue:** Line up several prompts and let the extension submit them one by one, waiting for each answer before the next.
- **Files and images in the chat:** Select a text file to submit directly into ChatGPT and surface related images inline in the conversation.

**Strengths:** Fully voice-driven loop: speak in, listen out; Saved prompts plus prompt injection cut repetitive typing; Auto-prompt queue is genuinely useful for batch requests; Small and lightweight with no visible subscription tiers

**Limitations:** Only automates the existing ChatGPT web page rather than providing its own chat interface; Speech recognition quality depends on your browser and microphone setup; Very small install base and last update in 2023, so long-term maintenance is uncertain

## 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
