# Alpha Hub
|
|
|
|
Research agents hallucinate paper details and forget what they learn in a session. Alpha Hub gives them semantic paper search, AI-generated reports, and persistent annotations — so they get smarter with every task. Search and content powered by [alphaXiv](https://alphaxiv.org).

|
## Quick Start
|
|
|
|
```bash
|
|
npm install -g @alpha-hub/cli
|
|
alpha login # sign in with alphaXiv
|
|
alpha search "attention mechanism" # search papers
|
|
alpha get 1706.03762 # fetch paper report
|
|
```
|
|
|
|
## How It Works
|
|
|
|
Alpha is designed for your coding agent to use (not for you to use!). You can prompt your agent to use it (e.g., "Use the CLI command `alpha` to search for papers on LoRA. Run `alpha` to see how it works.")
|
|
|
|
**Most of the time, it's simple — search, read, use:**
|
|
|
|
```bash
|
|
alpha search "transformer attention" # find relevant papers
|
|
alpha get 1706.03762 # fetch AI-generated paper report
|
|
# Agent reads the report, understands the paper. Done.
|
|
```
|
|
|
|
**When the agent discovers something useful**, it can annotate locally for next time:
|
|
|
|
```bash
|
|
alpha annotate 1706.03762 "Superseded by Flash Attention for efficiency"
|
|
|
|
# Next session, the annotation appears automatically on alpha get.
|
|
```
|
|
|
|
**Need to go deeper?** Ask questions about any paper:
|
|
|
|
```bash
|
|
alpha ask 1706.03762 "What datasets were used for evaluation?"
|
|
```
|
|
|
|
## Commands
|
|
|
|
| Command | Purpose |
|
|
|---------|---------|
|
|
| `alpha search <query>` | Search papers (semantic, keyword, or agentic) |
|
|
| `alpha get <id\|url>` | Fetch paper report + local annotation |
|
|
| `alpha ask <id\|url> <question>` | Ask a question about a paper |
|
|
| `alpha annotate <id> <note>` | Attach a note to a paper |
|
|
| `alpha annotate <id> --clear` | Remove a note |
|
|
| `alpha annotate --list` | List all notes |
|
|
| `alpha login` | Sign in with alphaXiv |
|
|
| `alpha logout` | Sign out |
|
|
|
|
All commands accept `--json` for machine-readable output.
|
|
|
|
## Self-Improving Agents
|
|
|
|
Alpha Hub is designed for a loop where agents get better over time.
|
|
|
|
**Annotations** are local notes that agents attach to papers. They persist across sessions and appear automatically on future fetches — so agents learn from past experience.

## Key Features
|
|
|
|
### Semantic Search
|
|
|
|
Three search modes — semantic (embedding similarity), keyword (exact terms), and agentic (multi-turn retrieval) — so agents find the right papers regardless of how they phrase the query.
|
|
|
|
```bash
|
|
alpha search "methods for reducing hallucination in LLMs" # semantic
|
|
alpha search "LoRA" --mode keyword # keyword
|
|
```
|
|
|
|
### Paper Q&A
|
|
|
|
Ask questions about any paper without reading the full PDF. The answer is grounded in the paper's actual content.
|
|
|
|
```bash
|
|
alpha ask 2106.09685 "What is the rank used for the low-rank matrices?"
|
|
```
|
|
|
|
### Annotations
|
|
|
|
Local notes that agents attach to papers — they persist across sessions and appear automatically on future fetches. See the annotation as a gap the agent discovered and recorded so it doesn't repeat the same mistake.
