Are Free AI Tools on the Web Really Enough?
Common frustrations that limit your AI experience
Have You Experienced This?
"This feature is amazing, but I hit the daily limit after just 5 requests. Now I have to wait until tomorrow."
Severe usage limitations on free AI services
"I requested a LinkedIn summary, and the response took over 2 days to come back. What's the point?"
Unbearable queues & waiting times
"That amazing free AI tool I bookmarked last week is completely gone now. The entire site has vanished!"
Promising services disappear overnight
"This site wants my OpenAI API key... How do I know they won't misuse it or charge thousands to my account?"
Serious credential security concerns
These frustrations are the reality for many web AI services. But why?
Developers Are Struggling Too
Behind every convenient AI feature is a significant cost.
While developers want to provide unlimited, fast, and powerful AI features to all users, the financial burden is often too great.
Dreams Halted by API Costs
"I built an AI idea validator but couldn't launch it with only $10 left in my OpenAI account. The API costs would have bankrupted me in days."
Personal projects killed by API costs
Unmanageable Costs
"Our AI tool went viral on Product Hunt. Two weeks later: $50,000 OpenAI bill. Had to shut down instantly. What should have been our big break became our downfall."
Viral success leads to financial disaster
Innovation Roadblocks
"Faced with bankruptcy or feature limits, we chose limits. As a result, ratings tanked. Users can't understand why they only get 5 requests per day when competitors offer 'unlimited' access."
User experience sacrificed to control costs

Securely Connect Your AI Models via MicroLLM
Discover the simple 4-step process to connect your AI models to third-party applications through MicroLLM.
Find the Connection Point in Supported Apps
Start by looking for a "Connect with MicroLLM" (or a similarly named) button within third-party applications.
Important: This option is only available in apps where developers have integrated MicroLLM to enable secure model connections for their users.
Sign In & Authorize Models
You'll be redirected to MicroLLM to sign in or create an account. First-time users may need to register their AI models (e.g., by providing API keys). Finally, select your desired models for the application.
Apply Your MicroLLM User Token
Once models are connected, MicroLLM issues an app-specific 'User Token'. Copy this token and paste it where the third-party app requires (e.g., settings page, AI feature input).
Important: This User Token is NOT your actual API key. It's a secure bridge between the app and your AI models.
Use Services with Your Models!
That's it! You can now use all AI features within the app, powered by your chosen AI models, without ever exposing your API keys. Enjoy a more powerful and personalized experience.

Why I Built MicroLLM
A journey from token costs to a simpler solution for developers and users
Song
Maintainer of Co-op Translator, an Azure open-source project
When I first joined Co-op Translator, a free web-based translation tool, I faced a challenge: translations consumed expensive Azure OpenAI and Computer Vision tokens, but as a non-commercial open-source tool, we had no billing system.
The Initial Solution:
Users had to paste their own API keys directly into the browser to run translations using their own tokens.
It technically worked, but created problems:
- Security concerns (trusting the page with sensitive keys)
- No portability or reusability
- Poor user experience (manually managing keys for each tool)
I reworked the project into a CLI tool where users could set environment variables and run translations locally with better privacy. But that raised a bigger question:
"What if there are hundreds of AI tools? Are users expected to manage their API key manually for every single one?"
That's when MicroLLM was born
What if users could connect their API key once and securely use it across tools without ever exposing it again? What if developers could ship AI-powered features without storing keys, paying for tokens, or maintaining proxies?
Just like Stripe processes payments without revealing card details, MicroLLM relays AI prompts without ever touching user keys or data.
