Have you ever wished you could browse Hive by topic rather than scrolling through a chronological feed? That's exactly what HiveComb does.
What is HiveComb?
HiveComb (https://hivecomb.net) is a content discovery layer for the Hive blockchain. It streams every post published on-chain, classifies it by topic, language, and sentiment using AI-powered semantic analysis, and lets you browse the results through a clean, filterable interface.
The entire codebase — backend, frontend, worker pipeline, classification engine — was written by Claude (Anthropic's AI), with 
No new account needed — log in with Hive Keychain and you're set.
How does it work?
A background worker continuously watches the blockchain. For every new post, it figures out what the post is about, what language it's written in, and whether the tone is positive, neutral, or negative. A second worker walks backwards through Hive's history, so older posts get classified too.
Low-reputation accounts and very short posts are filtered out to keep quality high.
The UI — HoneyComb
The discovery interface at https://hivecomb.net gives you:
Three view modes — hex grid, card grid, and list
Multi-filter browsing — combine topic, language, sentiment, and community filters to find exactly what you're looking for
Community discovery — browse Hive communities by topic, see post counts, subscribe and unsubscribe directly
Full posting & commenting — markdown editor with image upload, tag autocomplete, and a location picker (WorldMappin compatible). Reply to comments, vote on posts and comments — all broadcast through Keychain
Smart voting — vote weight adjusts automatically based on your voting mana, with configurable floor and max weight. Manual slider available too
Follow & Mute — build a "Following" feed, or hide accounts you don't want to see
Author profiles — click any 
Dark and light themes
Keyboard navigation — arrow keys to browse, H to vote, C to comment, Enter to open a post
Auto-saved drafts and on-chain preferences — your settings follow you across devices
Everything that touches the chain is signed client-side by Keychain. No private keys ever reach the server.
The API — Open for Builders
The API at https://combflow.net is public. Full interactive docs at combflow.net/docs.
Browse posts with filters:
GET /api/browse?category=crypto&language=en&sentiment=positive&limit=50
Combine categories, languages, communities, authors, and pagination however you like.
Get the category tree:
GET /categories
Get a post's classification:
GET /posts/{author}/{permlink}
Discover communities by topic:
GET /api/communities/suggested?category=crypto&category=programming
Languages and stats:
GET /api/languages
GET /api/stats
All responses are JSON with open CORS. Build a sentiment dashboard, a multilingual posting tracker, a topic-based feed for your app — the data is there for you to use.
What's Next?
HiveComb is actively being developed. Classification keeps improving, and the backfill worker is steadily processing Hive's history.
If you have feedback, ideas, or want to build something on top of the API — let me know in the comments or join the Discord.
