## Rumour

Rumour sits in your browser and adds a voice layer to the comment boxes you already use. Instead of typing a long paragraph of feedback into Google Docs, a Notion page, a Miro board or a Jira ticket, you speak it out loud; Rumour captures the audio, keeps it attached to the thread, and generates a written transcript so the note stays searchable and readable for anyone who prefers text.

The extension also handles language. Its transcription pipeline is paired with translation covering more than ten languages, which makes it practical for distributed teams where the reviewer, the author and the reader may not share a first language. Because the whole thing lives in the browser, there is nothing new to install inside each individual SaaS product, and no workflow change beyond clicking the extension while the comment box is open.

Rumour is published on the Chrome Web Store by Deefy.co and is distributed as a free extension, with no paid tiers or subscription plans advertised on its listing. The listing shows a small user base, a version 0.0.3 release dated January 2022, and no user ratings, so it is best treated as a basic, free utility rather than a heavily maintained commercial product. It declares that user activity and website content are handled by the extension, not sold to third parties and not used outside its core functionality.

**Pricing & Plans:** Free. Rumour is listed on the Chrome Web Store at no cost, with no paid plans, trials or in-app purchase tiers advertised.

- **Voice comments in any web comment box:** Speak your feedback instead of typing it, and attach the recording directly to the comment thread in apps you already use.
- **AI auto-transcription:** Spoken notes are converted into written text automatically, so voice feedback stays readable and searchable for teammates.
- **Translation into 10+ languages:** Transcribe once and let the extension translate the comment, which helps multilingual and distributed teams review the same thread.
- **Works across popular work apps:** Designed for comment boxes in G Suite / Google Workspace, Notion, Miro, Jira and similar browser-based tools, with no separate integration setup.
- **Browser-native and lightweight:** Everything runs from a single Chrome extension of roughly 6 MB, so there is no desktop app or per-product plugin to manage.

**Strengths:** Free to install from the Chrome Web Store with no paywall; Removes the friction of typing long feedback in web apps; Combines recording, transcription and translation in one extension; Fits into existing tools such as Google Docs, Notion, Miro and Jira

**Limitations:** Very small install base and no user ratings on the store listing; Last listed update dates to January 2022, so freshness is uncertain; Requires Chrome and permissions that read user activity and website content; Transcription and translation quality depend on audio clarity and language support

## 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
