Nebula is a Kaito alternative that measures which tokens own the crypto conversation — then goes further, scoring the emotion behind that attention, computing a Fear & Greed Index for 100,000+ individual tokens, and tracking the smart-money accounts that move markets first. Free live tools, a full app, and a developer API.
Crypto mindshare · sentiment · narratives · smart money
Kaito tells you what the market is paying attention to. Nebula tells you what it's paying attention to and how it feels about it — down to a single token — with public tools you can check without an account.
Open NebulaAn honest side-by-side. Kaito leads on attention markets and its launchpad; Nebula leads on per-token sentiment, Fear & Greed, and smart-money signals.
| Capability | Nebula | Kaito | What it means |
|---|---|---|---|
| Mindshare / share of attention | Yes | Yes | Both rank tokens by how much of the crypto conversation they own. |
| LLM sentiment & emotion scoring | Yes | Limited | Nebula scores how bullish or bearish each post is across a 15-emotion model, not just attention volume. |
| Per-token Fear & Greed Index | Yes | No | Nebula computes a dedicated Fear & Greed score for 100,000+ individual tokens. |
| Narrative / attention clusters | Yes | Limited | Nebula groups attention into tracked narratives so you can see which themes are heating up. |

| Coverage beyond X (Reddit, YouTube, news) | Yes | Yes | Both index multiple social and web surfaces, not just X/Twitter. |

| Developer API & agent access | Yes | Yes | Both expose their data to trading systems and agents via API. |

Kaito built the “mindshare” category and is the right tool for some jobs. A good alternative is honest about that.
Kaito Pro pairs an AI search engine over web3 sources with Attention Markets and a Capital Launchpad. If your workflow revolves around trading attention itself or running token sales, that ecosystem is Kaito's strength.
Kaito indexes governance forums, research, podcasts and conference transcripts into one searchable layer — useful for institutional research teams that need broad web3 coverage in a single place.
Kaito Studio connects creators and brands, and its mindshare arenas gamify attention. After Yaps was retired in January 2026, these remain the home for Kaito's creator ecosystem.
Nebula is built for traders and researchers who need to know how the market feels, token by token — not just where attention is pooling.
Nebula reads every relevant post with large language models and scores it across a 15-emotion model — separating loud-but-neutral chatter from genuine conviction. See it live on Market Sentiment.
Beyond a single market gauge, Nebula computes a Fear & Greed Index for 100,000+ tokens, so you can read sentiment for a specific coin, not just BTC.
The Mindshare Leaderboard shows what owns attention; Nebula layers on the callers and influencers driving it, so you see who is moving a narrative before it's obvious.
Live indexes are published as free public pages, and the same intelligence is available through the Nebula API for trading systems and agents.
You want to trade attention directly through prediction markets, run a merit-based token sale on the launchpad, or need a broad enterprise research index across web3 sources.
You want per-token sentiment and Fear & Greed, emotion-level social signals, smart-money and caller tracking, free public indexes, and a clean API — for trading, research, or building agents. Read the full Kaito vs Cookie vs LunarCrush vs Nebula comparison, or the best crypto sentiment tools guide.
Nebula is the closest like-for-like Kaito alternative for crypto social intelligence. It covers the same core job — measuring which tokens own the conversation — and adds emotion-level sentiment, a per-token Fear & Greed Index, narrative tracking, and smart-money signals. Other tools such as Cookie.fun and LunarCrush overlap on parts of this, but focus more narrowly on attention or social volume.
Yes. Nebula publishes several live indexes as free public pages you can use without an account, including the Crypto Fear & Greed Index, the Mindshare Leaderboard, and Market Sentiment. Paid plans unlock the full app, deeper history, and API access.
Kaito is built around attention capital markets — mindshare, an AI search engine, prediction markets, and a token launchpad. Nebula is a focused intelligence layer: it reads every relevant crypto post with large language models to score sentiment and emotion, computes Fear & Greed for individual tokens, and tracks the smart-money accounts moving attention. If you want the market and launchpad ecosystem, Kaito fits; if you want deep per-token sentiment and signals, Nebula fits.
Yes. Nebula ranks tokens by share of crypto conversation on its Mindshare Leaderboard, the same core metric Kaito popularised, and pairs it with a separate sentiment score so you can see not just what is being talked about but how the market feels about it.
Kaito sunset its Yaps post-to-earn program in January 2026, folding attention rewards into its other products. If you used Yaps mainly to gauge which projects and creators were gaining mindshare, Nebula’s free Mindshare Leaderboard and Top Influencers pages cover that use case directly.
See the crypto conversation — and how it feels.
