Create Professional Diagrams with Free Tools

Browser-based diagram editors bring several advantages compared to traditional software installations. For starters, they are accessible from any device with an internet connection. There's no need to download or install anything, making them highly portable and convenient - ideal for people who switch between devices or need to work while traveling. Another major perk is automatic updates. With these tools, you're always using the latest version without the hassle of manual updates. Many of these editors also offer collaboration, enabling multiple users to work on the same diagram at once. This feature is especially useful for remote teams or group projects, where seamless teamwork is key. These capabilities make browser-based diagram editors a practical and time-saving option, perfectly suited for today's fast-paced workflows.

What are the advantages of using a browser-based diagram editor instead of traditional software?

Free diagram editors place a strong emphasis on data security and privacy, employing measures to protect your sensitive information. Many of these tools allow you to store your work locally, ensuring your data remains on your device without being uploaded to external servers. Additionally, they often incorporate encryption to protect your data, both while it's stored and during any transfers, shielding it from unauthorized access.

The online AI Notepad features an AI assistance tool that enables you to generate, refine, and enhance text using a diverse range of AI models, both online and locally. 

Whether you're looking to spark new ideas, fine-tune existing content, or distil complex information, these advanced AI capabilities help you work more efficiently and creatively directly in your browser.

Although each tool has unique AI use cases, the overall usage and flow are consistent across tools.

Step 1: Locate and click on the settings icon at the bottom left of your browser window. This will open an AI dialogue box where you can select and configure your AI model, API keys, and preferences. 


Step 2: Click on the Model dropdown menu to reveal the list of available options. 

This list is divided into three (3) categories of AI models: 

Step 3: Select your desired model and use it accordingly. You may require additional configurations depending on your model choice; more information on this is provided in a later section.

Essential Considerations: What You Need to Know Upfront

Integrating AI requires awareness of certain constraints and trade-offs. Below are key factors to keep in mind:

Cloud-based AI models (e.g., via OpenRouter, or direct API access) require an active internet connection, while local models can function offline once downloaded and configured.

Cloud-based services often operate on a pay-per-use model or require AI credits. Local models incur no recurring API costs after initial setup, making them cost-effective for extensive use.

Local AI processing ensures your data never leaves your device. Cloud services handle data according to their respective privacy policies, which vary by provider.

While the UI supports multiple languages, AI features have been primarily tested in English; results in other languages may vary in accuracy and quality.

Selecting Your AI Model: Matching Power to Purpose

With a spectrum of AI models available, the key is understanding their strengths to choose the best co-pilot for your specific writing needs. This section breaks down the types of models and their ideal use cases.

These models are hosted on OpenAI servers, offering immense computational power and access to the latest advancements without taxing your local hardware.

Ideal For: Complex creative writing, in-depth analysis, comprehensive summarization of large texts, general knowledge queries, when internet access is reliable.

Smaller AI models that run directly within your web browser. Once downloaded, they offer immediate, private processing without needing an internet connection.

Ideal For: Sensitive personal notes, quick offline brainstorming, simple text expansion, basic rephrasing, when privacy is paramount or internet is unavailable.

Setup Note: Typically selected and downloaded directly within the AI-powered Online Notepad's interface. No external software required.

Dedicated Local AI Frameworks (Ollama/LM Studio)

These are desktop applications that allow you to run larger, more powerful open-source AI models directly on your computer. They offer the highest level of privacy and customization.

Ideal For: Running larger Llama, DeepSeek, Qwen or Mixtral models. Ideal for highly sensitive documents, extensive offline work, users with powerful local hardware (especially GPUs), experimenting with specific open-source models.

Setup Note: Requires installation of Ollama (Ollama.ai) or LM Studio(Recommended) and subsequent model downloads on your computer. Your writing tool connects to their local server.

OpenRouter acts as a unified gateway to a vast collection of AI models (both commercial and open-source) from various providers, all accessible through a single API key.

Ideal For: Accessing a wide variety of both commercial and open-source AI models through a single API key. This is the fastest way to experiment with diverse models like OpenAI's GPT and O-models, Gemini, Claude, and Llama 3(for free!).

OpenRouter’s catalog includes many of the most powerful models available publicly or commercially, organized below:

These get updates every week/month, balancing task needs, model fit and cost is key.

Setup Note: Requires creating an account and generating an API key at OpenRouter.ai. This key is then used to connect within your writing tool.

Once you've decided on the right AI model for your project, integrating it into your writing environment is straightforward.

Step 1: Select your desired cloud model from the list (e.g., 'GPT-4o,' 'GPT-4 Turbo') and enter your OpenAI API key.

Step 1: Choose a browser-based local model from the available options. Your tool will typically prompt you to initiate a one-time download directly into your browser's local storage. This usually happens automatically upon first selection.

The first time you select a browser model, it will automatically download weights to your local storage. Subsequent usages are instantaneous and do not require re-downloading, as long as the model remains cached.

 and ensure that either is running on your computer.

Step 2: In your online notepad's AI settings, select Ollama/LM Studio model option. You'll be prompted to connect to your local server (enter server endpoint URL). If Ollama is currently running on your system, the default endpoint URL is:

Tip: Always refer to the official documentation of 

 for the most accurate and up-to-date instructions on installation and model management.

, create an account, and generate an API key from your dashboard.

Step 2: In your notepad's AI settings, select your preferred OpenRouter Model, and enter your API key in the provided text box.
