VoiceLark is an AI news aggregation and sentiment analysis tool for the cryptocurrency market, designed to help users keep track of market sentiment and developments in real time.
Main capabilities
- Real-time content aggregation: Every day it collects approximately 1,100 to 1,400 cryptocurrency-related news articles from more than 110 global sources, so users can get information without browsing multiple websites. Each news item includes the publication time, title, source name, and the cryptocurrency tickers involved.
- AI sentiment analysis: The system performs sentiment evaluation on each article, giving a positive, neutral, or negative judgment and presenting it as a score from -1 to 1 (negative -1 to -0.2, neutral -0.2 to 0.2, positive 0.2 to 1). AI also generates the reason for the sentiment judgment to help understand the context. Sentiment scores are displayed as color bars for quick judgment.
- News summary generation: AI automatically generates concise summaries for news, which are displayed on the right side of the interface when the news is clicked; each news item also comes with an AI-generated sentiment explanation.
- Advanced filtering and search: Search news by keyword, cryptocurrency, or source; supports filtering by date range and even by hour; clicking a source name automatically filters news from that source.
Market sentiment and ranking features
- MARKET CAP: Track popular cryptocurrencies by market capitalization, with sentiment analysis for 1-hour, 24-hour, 7-day, and 30-day intervals.
- MOST MENTIONED: See the currently most-mentioned assets (1 hour to 30 days); rising mention volume may indicate growing investor interest.
- BEST SENTIMENT: Discover coins whose positive sentiment exceeds 70% and which are mentioned most frequently within a certain time period.
- WORST SENTIMENT: Monitor negative coins with sentiment below -20%, which helps avoid risk.
- TOP CRYPTO ranking: Every 6 hours, 20 coins are selected from the top 200 by market capitalization and ranked comprehensively based on news mention volume, 30-day price change, and average sentiment (the three factors are weighted equally), prioritizing assets with positive sentiment, more media coverage, and stable price growth; a historical ranking tab is provided, and you can view the price change of an asset since it first appeared on the list.
- Sentiment aggregation and charts: Market sentiment is calculated in real time based on the sentiment of individual news items from more than 110 sources, with data provided for 1-hour, 24-hour, 7-day, and 30-day intervals; a pie chart shows the proportion of positive, neutral, and negative sentiment in each time period; a line chart shows how market sentiment changes over time, with the Bitcoin price line as a reference, making it easy to analyze the relationship between sentiment and BTC price.
