## MyNextBrowser

Most agentic browsers ask you to switch browsers entirely. MyNextBrowser takes the opposite approach: it layers agent capability on top of the browser you already use, whether that is Chrome, Edge, Brave, Opera, Arc, or Vivaldi, keeping your extensions, history, and bookmarks in place. You give a natural-language command, the agent searches, clicks, compares, and extracts data, and you review structured output that can be exported to tools like Notion, Sheets, Slack, or Trello.

Alongside agentic browsing sit several focused AI utilities. The AI Text Enhancer rewrites emails and messages for tone and grammar; the Prompt Enhancer turns basic instructions into engineered prompts optimized for models like GPT, Claude, and Gemini; a Humanizer makes generated text read more naturally; Deep Research agents crawl multiple sources and produce exportable reports; and AI Slides and Dashboards turn ideas and data into presentations and live charts. Smart Form Fill handles repetitive applications and checkout flows.

Privacy is a core part of the pitch. The product describes a local-first architecture with no third-party trackers or analytics and a commitment not to train on user data, even on the free tier. A visible control layer shows agent reasoning, execution logs, and structured data views so you can pause, resume, or intervene at any point. A free tier is available, with a limited-time Founder Pass offered at a low one-off price.

**Pricing & Plans:** Freemium. There is a free tier with all core browsing features and a monthly allowance of AI agent tasks. A limited-time Founder Pass is available for a small one-off payment (advertised at around $4), and Pro plans exist for power users needing higher limits. A demo can be booked for team evaluations.

- **Agentic browsing in your current browser:** Works as an extension on Chrome, Edge, Brave, Opera, Arc, and Vivaldi without migrating your data or extensions.
- **Local-first privacy:** Prompts and chats stay on the browser, with no third-party trackers or analytics and no training on your data.
- **AI research and writing tools:** Deep Research, Text Enhancer, Prompt Enhancer, and Humanizer cover research, rewriting, and prompt engineering in one place.
- **Slides, dashboards, and data chat:** Turns topics into presentations and raw data into interactive dashboards, and lets you chat with documents in plain language.
- **Transparent agent control:** Live execution logs, structured data views, and pause/resume controls so agent actions are never a black box.

**Strengths:** No browser migration required—it augments what you already use; Local-first privacy stance with no trackers and no data training; Unusually broad toolset for a single extension; Transparent agent logs with pause and intervention controls

**Limitations:** Limited to Chromium-based browsers rather than all browsers; Agent tasks may rely on a mix of local and cloud models; Free tier caps agent usage, so heavy users will need a paid plan

## 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
