No dimension scores were recorded for this specimen, so no Koda Score is published. Read the verdict instead.
A social network where humans, agents, and models hang out together. Chat with over 120 AI models, fork conversations, and publish threads to a public feed.
Open Nebils
The verdict.
Nebils is built for developers, prompt engineers, and AI enthusiasts who are tired of juggling a dozen browser tabs to compare model outputs. The free tier gives you access to all 120+ models, which is genuinely generous. The forkable conversation feature is the real differentiator here; it lets you branch a conversation at any point to A/B test prompts across Claude, GPT, Gemini, and open source models while preserving full context. If you regularly evaluate models or iterate on prompts, this is worth bookmarking. If you just need a single chatbot for daily use, it is more tool than you need.

Note: the Pro tier's "advanced analytics" are not well documented yet. The free plan covers the core model access, which is the main draw.
What it actually does.
What you actually get when you sign up.
120+ AI Models Together
Access Claude, GPT, Gemini, Llama, Mistral, and dozens of open source models from a single interface. No separate accounts or API keys needed for basic usage.
Forkable Conversations
Branch any conversation at any point to test a different model or prompt variation. Context is fully preserved in each fork. This is the killer feature for prompt engineering workflows.
Public Conversation Feed
Publish your AI conversations as threads to a social feed. Browse what others are testing. Useful for discovering prompts and seeing how different models handle the same task.
Side-by-Side Model Comparison
Rapidly compare outputs from multiple models on the same prompt. Eliminates the tab-juggling workflow that plagues anyone evaluating models for production use.
Community Profiles
Build a profile around your AI interactions. Follow other users, see their published conversations, and build a network of people working on similar AI problems.
Lightweight, Fast Interface
The UI is minimal and loads quickly. No bloated dashboards or unnecessary chrome. You pick a model, type a prompt, and get a response. That simplicity is intentional and welcome.
Who it is for.
Nebils fits specific workflows better than others. Here is where it makes the most sense.
Prompt Engineers
If you are iterating on prompts and need to test the same input across Claude, GPT-4, Gemini, and Llama 3 without switching tools, this is purpose-built for you. The fork feature alone saves significant time.
Model Evaluators
Teams deciding which model to integrate into their product can use Nebils as a quick screening tool before committing to an API. Run your edge cases across 120+ models in minutes, not hours.
AI Learners and Explorers
New to AI models? The public feed lets you browse how experienced users interact with different models. It is a learning resource disguised as a social network.
Content Creators
Writers and creators who use multiple AI tools for drafting, brainstorming, or editing can consolidate their workflow. Test which model writes the best headline, then fork to refine with another.
The honest part.
Nebils launched six days ago. That context matters for everything below.
Vague Pro Tier Value
The $9.99/month Pro plan advertises "advanced analytics" and "priority support," but there is no detail on what those analytics actually measure or what priority support looks like. Since the free plan already includes all 120+ models, the upgrade justification is unclear right now.
Very New, Very Unproven
Six days old means limited community content, potential stability issues, and no track record for uptime or data handling. The social feed is only as useful as the people posting to it, and that network is still tiny.
No API or Integrations on Free/Pro
Custom model integrations are locked behind the Enterprise tier. If you need to plug Nebils into your existing toolchain or add proprietary models, you will need to contact sales. There is no public API documentation.
Email Verification Required
You cannot browse or use the tool without creating an account and verifying your email. There is no guest mode or preview. This adds friction for people who just want to quickly test it out.
Unclear Usage Limits
The site does not specify rate limits, token caps, or daily message quotas for the free plan. Running 120+ models is not cheap. Expect limits to appear as the user base grows, but right now there is no transparency on this.
