MyNextBrowser

MyNextBrowser is an agentic browser extension for Chromium-based browsers that adds AI-driven research, writing, slides, analysis, form filling, and inbox help to an existing browsing setup. It offers a free tier and a paid Founder Pass, with local-first handling for chats and prompts.

MyNextBrowser

Overview

MyNextBrowser is an agentic browser extension for Chromium-based browsers. It layers AI agents onto an existing browsing setup so users can research, rewrite, present, analyze, shop, and handle routine web tasks without migrating away from their current browser.

The product combines local-first browser automation with several focused AI tools, including text enhancement, prompt enhancement, deep research, slides, dashboards, smart form fill, and inbox chat. The site emphasizes that chats and prompts remain local, with no third-party trackers or analytics, and that users can review live execution logs, structured data, and agent actions as they happen.

Capabilities

Works with existing Chromium browsers

Layer agentic actions on top of your current browser instead of switching tools. The product is described as working with Chrome, Edge, Brave, Opera, Arc, and Vivaldi while keeping extensions, history, and bookmarks in place.

AI text enhancement

Rewrite emails, adjust tone, fix grammar, and expand rough text directly on the page. The site also positions this as a Humanizer for turning more casual copy into polished prose.

Prompt enhancement

Convert short instructions into better prompts for models such as GPT-5, Claude, and Gemini. The site says it engineers prompts to improve results from the AI tools you already use.

Deep research workflow

Crawl multiple sources, cross-reference facts, and summarize them into reports. The feature page also says the agent supports PDF export and can process 100+ sources per minute.

Presentation and analysis output

Create slides and dashboards from source material or data. The site describes AI Slides for formatted presentations and AI Dashboards for interactive, real-time charts and metrics.

Form filling and data interaction

Fill forms, job applications, and checkout flows automatically, and chat with Gmail to find information or summarize messages. The product also says it can answer questions about documents, graphs, or browsing history in plain language.

Use Cases

  • Multi-source research

    Use the browser to search multiple sources, summarize what you find, and turn the result into a report or exportable PDF instead of copying notes by hand.

  • Writing and editing

    Draft an email, rewrite a rough note, or adjust tone directly on the page with the text enhancer when you need cleaner wording quickly.

  • Presentations

    Turn a topic or outline into a formatted slide deck, then use the generated speaker notes and images as a starting point for a presentation.

  • Data review and analysis

    Ask questions about uploaded data, charts, documents, or browsing history and use the dashboard tools to inspect trends and metrics.

  • Form and checkout automation

    Ask the agent to fill web forms, applications, or checkout flows when repetitive typing is the main bottleneck.
