The Top 3 MonkeyLearn Alternatives for Sentiment Analysis in 2024

Are you looking to implement sentiment analysis to gain insights from customer feedback and survey data? With so many options to choose from, it can be tricky to determine the best vendor for your specific needs.

In this comprehensive guide, we‘ll be exploring the top 3 leading alternatives to MonkeyLearn for sentiment analysis in 2024. I‘ll provide detailed comparisons of their accuracy, features, use cases, and pricing models.

My goal is to equip you with everything needed to determine the right sentiment analysis platform based on your business requirements, data complexity, and budget. Let‘s dive in!

Why Sentiment Analysis Matters

Before reviewing the top vendors, it‘s helpful to understand why sentiment analysis has become so valuable:

  • Customer insights – Analyze feedback, surveys, support tickets to understand needs and pain points. Sentiment analysis provides quantifiable data to guide decisions.
  • Market research – Monitor social media, reviews, forums to identify new trends, opportunities, and threats in near real-time.
  • Risk detection – Identify negative sentiment towards your brand and get ahead of reputation crises.
  • Competitive intel – Analyze competitor mentions, their product reviews, and customer feedback to compare against your own.

According to IndustryARC, the sentiment analytics market is projected to reach $7.5 billion by 2027, growing at 22% CAGR [1]. With more data to analyze than ever before, the need for robust sentiment analysis keeps increasing.

Overview of MonkeyLearn

Before covering the alternatives, let‘s briefly recap MonkeyLearn‘s platform. Founded in 2010, they provide a cloud-based suite of text analysis tools including:

  • Sentiment analysis
  • Entity/keyword extraction
  • Language detection
  • Text classification

Their architecture enables real-time analysis of data via API calls. You send text, MonkeyLearn processes it through their models, and returns categorized results and metadata.

MonkeyLearn‘s strengths are ease-of-use and broad language support. Their API documentation is excellent. And they offer affordable starter plans beginning at $299/month.

However, for more complex data, MonkeyLearn can fall short. Their pretrained models offer 70-85% accuracy when tested across various datasets [2]. For nuanced text, customization is required.

For companies with simple classification needs or limited data science resources, MonkeyLearn provides a solid ready-to-use solution. But for advanced use cases, the following alternatives are worth considering.

Top MonkeyLearn Alternative #1: Appen

Appen is a leader in training high-accuracy AI models through human-annotated machine learning. Their specialty is creating custom datasets and models for enterprise needs.

Appen‘s Custom AI Approach

Appen utilizes a crowdsourced workforce of over 1 million data annotators, linguists, and project managers. This global team labels complex client data to build custom training datasets.

They clean, preprocess, and structure the data for each project. Appen‘s data scientists then work closely with clients to iteratively train machine learning models that classify text with over 90% accuracy.

For example, one logistics company used Appen to build a bespoke model to analyze shipment complaints on social media. By accurately identifying complaint types, they reduced resolution time by 50% [3].

Appen also handles model deployment through integrations and easy-to-use APIs. Their end-to-end approach maximizes accuracy for each client‘s unique data.

Ideal Use Cases

Appen is ideal for large enterprises with:

  • Domain-specific textual data
  • Compliance requirements
  • Needs for extremely high accuracy
  • Ongoing model improvement

They excel at complex multilingual projects. And their managed service minimizes in-house AI expertise needed.


As a managed enterprise solution, Appen is more expensive than self-serve platforms. They provide custom quotes based on project complexity. But their accuracy and degree of customization exceeds most alternatives.

For rapidly evolving models though, some continuous costs may be required. So total TCO can add up, requiring larger ROI to justify.

Overall Appen offers unparalleled accuracy and customization for enterprise needs. But their managed service approach may be overkill for many.

Top MonkeyLearn Alternative #2: Clickworker

Clickworker combines the power of crowdsourcing with AI to classify complex text. Their hybrid workforce approach helps achieve greater accuracy more cost effectively.

Crowdsourced Data Annotation

Like Appen, Clickworker leverages crowdsourcing to label training data for sentiment analysis and other natural language tasks.

Their global network of over 1 million freelance "clickworkers" can annotate massive datasets with human insight much faster than in-house teams. Common tasks include:

  • Sentiment labeling
  • Entity recognition
  • Text translation
  • Data categorization

This human-labeled data is used to train machine learning algorithms to interpret and classify complex documents and social posts with nuance.

Clickworker‘s platform enables you to assign tasks, define guidelines, and monitor progress in real-time. Their workforce speaks over 50 languages enabling accurate multilingual models.

Self-Serve Platform

Unlike managed services, Clickworker is a self-serve platform. You can launch annotation projects on demand using their intuitive web dashboard.

Pricing depends on the size of data needing annotation, turnaround time, and other variables. Small projects can start for less than $1,000.

For teams with data science skills looking to train custom sentiment analysis models affordably, Clickworker hits the sweet spot. You retain control without the overhead of hiring in-house annotators.

Impressive Accuracy

Studies show Clickworker‘s hybrid approach achieves accuracy near 90% for complex sentiment classification [4].

This rivals expensive enterprise solutions. For regulated industries or complex multilingual datasets, Clickworker provides an appealing mid-market option.

Top MonkeyLearn Alternative #3: Repustate

Repustate offers an affordable self-serve sentiment analysis API. Their natural language processing (NLP) technology combines rule-based analysis with machine learning.

Hybrid NLP Approach

Repustate‘s API uses a hybrid approach:

  • Rule-based – Rule sets fine tuned over 7+ years classify basic language structure and emotional tones.
  • Machine learning – Repustate trains classifiers on millions of social media posts, reviews, and forum data to identify common sentiment patterns. Their models continue to learn from new data sources.

This dual technique allows accurate analysis of longer-form content out of the box. You can further tune accuracy by submitting in-domain data for custom model training.

Intuitive API

Their API offers real-time sentiment scoring and other analysis including:

  • Positive/negative/neutral classification
  • Keyword extraction
  • Topic detection

Integration is simple across languages. And the dashboard allows easy monitoring and alerts configuration.

Pricing starts at just $199 month for up to 10,000 requests, making it very affordable. Free trials are also available to test it out.

When Repustate Excels

For lean startups and SMBs seeking accurate sentiment analysis without a big commitment, Repustate hits the mark.

Their API requires minimal implementation effort. And custom training options allow improving accuracy on your data over time.

Downsides include less features than MonkeyLearn and lacking the customization of enterprise vendors. But for most basic use cases, Repustate delivers immense value.
