Description

SecondBrain: The Prompt Optimizer That Refines, Explains, and Saves Your Best Work Stop wrestling with AI to get the output you need. You write an instruction, the chatbot misinterprets it, and you waste ten minutes iterating. SecondBrain is a transparent prompt optimizer built specifically for everyday AI users. We clarify your intent, tighten your wording, and show you exactly what changed. Once you secure the perfect result, you can instantly build a library of repeatable requests. Try it with the next prompt you were about to rewrite manually. WHAT DOES SECONDBRAIN DO? SecondBrain is a Chrome extension that functions as a transparent prompt optimizer. It refines your rough AI instructions into precise, highly effective prompts by cutting fluff and clarifying your core intent. Once you achieve the perfect output, you can save and bookmark prompts directly in your browser for fast retrieval on repeatable tasks. How This Prompt Optimizer Transforms Your Workflow TL;DR Key Takeaways: Clarifies intent: Turns vague requests into precise instructions. Ensures consistency: Delivers reliable formatting for recurring AI tasks. Integrates seamlessly: Works inside your current chat environment. Turn vague input into clear directives We tighten your wording so the AI understands exactly what you require. We preserve your original context. We only add structure when it actively improves the result. We cut the useless filler immediately. Get consistent AI output every time Better task framing leads to reliable formatting. Whether you are writing, researching, or debugging code, you get repeatable results for recurring tasks. You no longer have to guess how the AI will respond. Fit directly into your existing habits You start with a messy research idea, refine it with one click, and send the cleaner version in seconds. Use this tool exactly where you already chat with AI to eliminate manual rewriting. See the Edits Before You Send The fastest way to trust an optimization tool is to see it improve your own words in real-time. Before (The Original Request) Imagine starting with a vague request for a blog draft. It lacks direction. It leaves too much room for the AI to guess your target audience and formatting requirements. After (The Optimized Request) We refine that exact intent with absolute clarity. You receive the specific structure you need without any obvious padding. What changed and why: Goal clarified: The core objective is front-loaded. Filler removed: Unnecessary conversational text is deleted. Format defined: Output constraints are explicitly listed. Context preserved: Your original parameters remain intact. Save Prompts and Bookmark Prompts That Actually Work TL;DR: Never lose good work: Save successful prompts instantly. Organize easily: Bookmark by project or outcome. Build a system: Create a reliable personal library over time. Save prompts by specific task or project Stop losing your best work to the chat history feed. Start saving prompts for repeat use so you can retrieve them instantly. This maintains your output quality over time. Bookmark prompts for instant reuse Keep highly effective instructions close at hand with a lightweight saving habit. This completely eliminates the need for endless scrolling to find that one template that worked last week. Build a highly functional personal library Focus strictly on quality. Keep only the instructions that consistently prove useful. You will build a reliable workflow system instead of a random, messy pile of text. Practical Use Cases Across Your AI Workflow SecondBrain adapts to the exact tasks you repeat daily. Writing and Editing: Clean up tone, tighten drafts, and structure content briefs fast. Researching: Refine complex queries, build comparison matrices, and synthesize scattered notes. Coding: Request tighter code blocks, format debugging tasks, and write precise bug reports. Structuring Output: Generate reliable tables, lists, and reusable frameworks. Works with the AI tools you already use Use it fluidly alongside ChatGPT, Claude, Deepseek, Grok, MetaAI, and Gemini. Quick Answers Before You Install (FAQ) Does it always make text longer? No. Highly effective instructions are often concise and well-structured. We cut fluff instead of adding it. Can I save prompts and bookmark prompts for later? Yes. You can bookmark inputs immediately and retrieve them through our streamlined library interface. Is it useful for simple, one-sentence queries? Simple queries often work fine natively. The biggest performance gains occur when your requests are nuanced, multi-step, or frequently repeated. Will it work inside my favorite AI chat interfaces? Yes. It operates directly inside the native environments of major AI platforms. Is an API key required? You do not need an API key to start. Install the extension and begin optimizing immediately. Close the Gap Between a Rough Idea and Perfect Output Start communicating with AI precisely. Generate clearer instructions without the bloat. View exact text improvements and understand the logic behind them. Build an easily accessible library of saved prompts. Install the top prompt optimizer today and watch your next request improve before you hit send.

Used this as the only functioning Gemini in Chrome since the original Website version can't even run PRO without Chrome freezing and dying over it. Today it changed into a Prompt Editor only after working fine this morning, no Gemini anymore which is useless as heck for me, because now I am forced to use Firefox to run Gemini without constant browser crashes. And since we in Germany do not have the Gemini sidepanel in Chrome yet or ever, because... AI phobia or whatever... I'm pretty much annoyed...

I have installed this as "Google Gemini sidebar", but today, it surprisingly changed. I don't need it anymore.

Floating button sucks. It's just Gemini loaded in a sidebar: keep it simple people.

Well, this used to work, except now in addition to other users' problem of adding 2options for the sidebar that don't maintain text (pointless and time consuming) there is no text box available on the sidebar. The extension has become unusable.

The latest update's right-click icon now first brings up a search bar, which then transitions to Gemini. This user experience feels really poor. If possible, please allow users to choose whether to enable this feature. If this request can be met, I will leave a high rating.

There's a huge disconnect between what we see in the news / media regarding AI, and the reality. Or, the versions of the services we're getting are being massively restricted. How can it be true that everyone should fear for their jobs, yet Gemini can't move emails to a folder based on the content... As for not being able to see content of the page, it makes it completely irrelevant as an extension. It's a bit like getting an extension on your house that isn't attached to your house. Then there's the inability to retain information about previous conversations or the user. Google probably know how many times a day I drink tea, but the service they're selling me can't remember what I asked it 10 minutes ago? We're being sold a lemon, and it's by design.

what is the use of it if it cannot "see" the web page? me: summarise it extension: Please provide me with the text you would like me to summarize. I need the content to be able to help you. me: summarise this page extension: It's important to understand that "summarizing a page" can refer to a couple of different things, especially with the rise of AI: Summarizing web content using AI tools: Many AI tools and browser extensions are now available to generate concise summaries of web pages.

I use Gemini about 20-30 time in a hour , at least about 150-300 time in a day and thought this will save me lots of minutes / hour. But , instead , shortcut loading gemini take about 2-3 seconds! and what worse , I cannot type immediately when gemini open , so I have to manually click chat box again which take another 2 seconds ! so even more time consuming than Gemini chrome shortcut and put it on taskbar

Found it a bit useless as: 1. gemini keeps refusing the connect 2. its not reading the content/source of the web which is currently selected (I was aiming for it while searching the internet)

REMOVE THE LOGO ON THE BOTTOM RIGHT. Or at least add an option to remove it. It is disturbing.

This is a wrapper of gemini.google.com. We can already use gemni.google.com inside of Chrome in many places and many ways. For example, just enter your message to Gemini.google.com in search and URL bar with @ mark like "@this extension is a wrapper UI?" Furthermore, Google has already released "The Official Gemini GUI Functions for Chrome" now in English. This Gemini is Chrome's functions and GUI, not a just wrapper. In this system, Gemini is deeply integrated inside of Chrome to work mainly locally as one software. I recommend to try out the early Chrome build such as Canary, Dev, Beta for the fastest access of the usage not only in English. BTW, Chrome already includes Gemini Nano in Dev mode and General Usage who get it while the trial period.

Google Gemini is good, but way too expensive and ofcourse not value for money, Google should reduce the price ,,

Almost perfect, but please REMOVE THAT BUTTON It's so frustrating to have that little bubble that you can't remove

★★★☆☆2026-02-02

Works well but the developer needs to add an option to remove the floating icon on the bottom right of every page. It's annoying and can't be removed. Also add an option to remove the Google search bar. It's unnecessary & redundant since I can just search google in my normal browser. I'm only interested in the Gemini prompt-bar.

Uninstalled because of the annoying floating icon :( Otherwise great extension

Consider adding a screenshot tool inside it, so that the screenshots are temporary( I mean they shouldn't get saved the system memory). Please!

the new update is counter-intuitive. I want to access the sidebar quickly by clicking the icon. now it shows some screen with 2 things, and when I type my prompt in the left, it opens the sidebar without maintaining my text. Why tamper with something that was working perfectly.

Lorenzo Pulcinelli

Good but it lacks some features that would greatly improve the use, for example: - the ability to hide the side icon from the screen, the one that opens gemini on the sidebar; - the ability to open gemini by highlighting text on a web page, right click, open gemini and copy the text directly to the gemini text editor without having to retype or copy and paste; - the ability to open gemini and use it when using the browser as a pdf reader;

Can you please give the ability to remove that annoying floating button that shows up on every website. Why can't Google make their own extension for Gemini?
