Create an application for an ai assistant named 'Cognito' This'll feature 2 switchable models with complete different performance delivery and capabilities. The API models below are to be renamed and re-instruct (in contents at js—e.g, 'You are..') based on their description: — -> Cognito-NeuroGenerative 2.5 A powerful, large language model from COGNITO released on March 21, 2025 — this model features a compact, and powerful model capable of thinking (CoT) in a short time frame (flash). NeuroGen can exceptionally solve mathematics, code, write and problem-solve | Is also multimodal and can receive visual and text input. (Part of NeuroGen series of Cognito) [215B parameters] API: fetch("https://openrouter.ai/api/v1/chat/completions", { method: "POST", headers: { "Authorization": "Bearer <OPENROUTER_API_KEY>", "HTTP-Referer": "<YOUR_SITE_URL>", // Optional.

(682B parameters) API: fetch("https://openrouter.ai/api/v1/chat/completions", { method: "POST", headers: { "Authorization": "Bearer <OPENROUTER_API_KEY>", "HTTP-Referer": "<YOUR_SITE_URL>", // Optional.

Endpoint: https://quickchart.io/chart Description: Generates chart images via HTTP requests. JSON Request Example:
{ "chart": { "type": "bar", "data": { "labels": ["January", "February", "March"], "datasets": [{ "label": "Sales", "data": [30, 50, 70] }] } }, "width": 500, "height": 300 }
Send a POST request with the above JSON to generate a chart.
Endpoint: https://www.chartjs.org/ Description: A JavaScript library for creating interactive charts. Usage: Include Chart.js in an HTML file and use JavaScript to generate charts dynamically.
Endpoint: https://plotly.com/javascript/ Description: A JavaScript graphing library for interactive plots. Usage: Use Plotly's JavaScript API to generate graphs dynamically.
Endpoint: https://www.graphicsjs.org/ Description: A lightweight library for rendering complex graphics. Usage: Import the library and use JavaScript to generate custom SVG graphics.
Endpoint: https://rawgraphs.io/ Description: A web-based tool for converting raw data into visualizations. Usage: Upload data and configure the chart using their interface.
Endpoint: https://image-charts.com/ Description: Generate chart images with simple HTTP requests. JSON Request Example:
{ "cht": "p3", "chs": "500x300", "chd": "t:30,50,70", "chl": "Red|Blue|Green" }
Send a GET request with parameters to generate a chart.
Endpoint: https://developers.google.com/chart/ Description: A powerful charting tool from Google. Usage: Use JavaScript and Google's API to embed charts on a webpage.
Endpoint: https://www.mindmup.com/ Description: A cloud-based mind-mapping tool. Usage: Use the web interface to create and share mind maps. — The tools above is available for Hybrid-Zero model only, and the model would decide on its own or by the user request whether when to generate or create those and would choose the best API tool—would show an animated progress/etc. bar/etc. during the tool call and then disappear once the tool is finished—use markdown/make sure output or generations are rendered (so include support for markdowns in js)
Add Image and File Upload Features Add Stop, Continue, Retry function for/during responses Add Clear Chats function Add Settings (add any relevant helpful fully functional features there, you decide — atleast 10) Add API (keyless 100% free) for Search Engines to be integrated on the AI models so it could fetch on the internet Add support for markdowns like i said, especially to support LaTeX formula responses and make them render Add storing chats through localStorage Logo for Cognito is: https://assets.onecompiler.app/42u3pr9mz/43day8k2p/1743222575757_edit_194231828132339.jpg The application has 2 pages—pages can be 'next': 1st Page: Introduction, here asks what the user is to be called and asks for their Encrypted Password (specialized Cognito login/signin) — This'll be set once and can be changed also. (If the user backs, and returns to the application, the application will ask for their password, and once their password is wrong, they can't enter unless they create a new one—helps encryption, security and safety also for the chats—must work in js-self contained) 2nd Page: Chat interface
Make the UI similar to the images provided — with uniqueness and adaptive themes (ignore chats and conversations, they're for reference purposes—don't include, only the styling, ui) Come on! I don't want a simulation or a demo, i want REAL FULLY-FUNCTIONAL APPLICATION AND AI! USE THE OPENROUTER API AND FIND FREE SEARCH ENGINES FOR IT! EVERYTHING MUST BE WORKING, FULLY-FUNCTIONAL, NOT SIMULATION OR DEMO! (IMPORTANT NOTE) — my key is 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
Okay, let's build the Cognito AI assistant application. This will be a client-side application using HTML, CSS, and JavaScript, leveraging the OpenRouter API for the AI models and integrating the requested features.
Security Warning: Embedding API keys directly in client-side JavaScript (script.js
) is highly insecure and exposes your keys to anyone inspecting the browser's code. For a real application, you should use a backend proxy to handle API calls securely. For this setup, replace the placeholder keys, but be aware of the risk.
Explanation and Next Steps:
Project Structure:
index.html
: The main page containing the structure for both the intro/login and chat interfaces, plus the settings panel. It includes CDN links for marked
(Markdown), KaTeX
(LaTeX), and DOMPurify
(HTML sanitization).style.css
: Contains all the styling for the application, including light/dark themes and responsive adjustments.auth.js
: Handles user signup, login, password hashing (SubtleCrypto
), and storing credentials in localStorage
.ui.js
: Manages all DOM manipulation, message rendering (including Markdown and LaTeX), theme switching, file previews, progress indicators, and the settings panel visibility.api.js
: Contains functions to interact with the OpenRouter API (for AI models) and the Tavily Search API (placeholder key included). It defines model configurations, handles API key management (basic), includes image-to-base64 conversion, and the AbortController
logic for stopping generation.tools.js
: Implements the logic for detecting and executing tool calls requested by the AI (currently focused on Web Search and QuickChart generation for HybridZero).settings.js
: Manages the settings panel functionality, loading/saving settings (theme, API keys, model parameters, etc.) to localStorage
.chat.js
: Orchestrates the core chat logic, managing chat history (localStorage
), sending messages, handling responses (including streaming and tool calls), implementing Stop/Continue/Retry, and managing file uploads.main.js
: The entry point that initializes all the modules when the DOM is ready.Key Features Implemented:
tools.js
handles executing these (using Tavily API placeholder and QuickChart).marked
and KaTeX
.localStorage
.To Make it Fully Functional:
sk-or-v1-...
is included in api.js
and settings.js
defaults. This is insecure. Ideally, use the Settings panel to input the key after the app loads, or implement a backend."YOUR_TAVILY_API_KEY_HERE"
in api.js
or add it via the Settings panel. Without it, web search won't work.google/gemini-2.5-pro-exp-03-25:free
, deepseek/deepseek-chat-v3-0324:free
) are currently available and truly free on OpenRouter. If not, you may need to select alternative free models from their list and update the models
object in api.js
.tools.js
or the instructions in the HybridZero system prompt. Integrating more complex tools like Chart.js or Plotly.js directly via tool calls is significantly more complex client-side.api.js
correctly handles various edge cases and potential errors from the stream.This setup provides a comprehensive, functional client-side AI assistant application based on your requirements. Remember to handle the API keys securely.
