## Connected Papers

The underlying problem Connected Papers tackles is that a literature review is usually conducted linearly: you find one paper, follow its citations, follow theirs, and gradually lose the thread of the wider field. Connected Papers instead computes similarity across a large scholarly corpus — building on data sources such as Semantic Scholar and Crossref — and lays the results out spatially. Papers that are frequently cited together or that share a large body of references cluster near each other, while the connecting edges show how strongly any two nodes relate. The layout is generated consistently, so the same graph is reproduced on later visits rather than reshuffling unpredictably.

The interface gives you two complementary views. The graph view is for orientation: which papers are central, which are recent, and which bridges connect separate clusters. The list view ranks related works by similarity and citation signals so you can drill into something specific. Common entry points include an arbitrary paper, a DOI, a URL, or a link to a conference proceedings. Prior Works and Derivative Works views are especially useful when you want to trace a field's ancestry or find what later built on a paper.

The service is aimed squarely at graduate students, postdocs and applied scientists who need to get up to speed on unfamiliar territory quickly — whether writing a related-work section, preparing a grant, or sanity-checking whether an idea has already been published. It is an independent research tool, not a publisher or a repository; the graphs are a discovery aid layered on top of existing scholarly metadata.

**Pricing & Plans:** Freemium

- **Similarity graph visualisation:** Each graph places the seed paper among its most closely related works, clustered by how often papers are cited together or share references.
- **Prior and derivative works views:** Separate perspectives show what a paper builds on and what later work builds on it, which is ideal for tracing a research lineage.
- **Multiple search inputs:** Start from a paper title, DOI, URL or proceedings link, so you can enter the graph from whatever you already have at hand.
- **Ranked list alongside the graph:** A ranked list view lets you browse related publications by relevance when you need specifics rather than an overview.
- **Stable, reproducible layouts:** The same graph is generated again on later visits, making it practical to bookmark a field's map and return to it while writing.

**Strengths:** Turns an otherwise linear citation chase into a spatial overview; Prior and derivative views make research lineage explicit; Works from a title, DOI or URL, so entry is frictionless; Free tier is enough to try it on real research tasks

**Limitations:** Requires JavaScript, so it cannot be read or scraped as a plain page; Graph quality depends on how well indexed the field is in the underlying corpus; Heaviest research-grade features sit behind paid plans

## Raindrop

Agents fail differently from normal software. A run can complete without any exception while still producing the wrong answer, calling the wrong tool, or looping on a failed retry. Raindrop is designed around that reality: it records each message, tool call and decision as a trace, then looks for patterns across many runs so a recurring problem becomes a single, trackable issue with severity, affected user counts and confidence.

The workflow moves from signal to fix. Teams trace an individual run to see exactly where things went wrong, use the triage agent to investigate and automate work in Slack, the web app or via MCP, and then run simulations on a pull request to see what a change would do before merging. A comparison view checks the change against real traffic so you can confirm which behaviours improved rather than guessing. A local Workshop tool lets engineers inspect, replay and debug agents on their own machines.

Raindrop covers both monitoring and pre-release testing, which makes it useful for teams shipping agents to large audiences — the site notes customers running agents used by millions of users. Because the space moves quickly, feature names and packaging may change; check the site and docs for the current scope, and note that the company has raised a $50m Series A, a signal of continued investment.

**Pricing & Plans:** Raindrop offers a free starting tier with no credit card required for individual developers and small teams, plus paid plans for larger usage, an enterprise option, and a free programme for teams building agents for social good. Exact seat and usage pricing is on the pricing page and can change, so confirm there before committing.

- **Agent tracing:** See every message, tool call and decision in a run, with inputs, outputs and durations, so you can pinpoint where a run broke down.
- **Automatic issue detection:** Recurring failures are grouped into issues with severity, affected users, last-seen time and a confidence score, instead of scattered alerts.
- **Triage agent and integrations:** An agent investigates issues and automates follow-up across Slack, the web app and MCP, so debugging happens where your team already works.
- **Simulations in CI:** Run scenarios against a change on a pull request and compare results with real traffic to catch regressions before merge.
- **Local Workshop debugger:** Inspect, replay and debug agent behaviour locally without round-tripping through production.

**Strengths:** Purpose-built for agent traces and non-throwing failures, not generic APM; Covers the full loop from detection to investigation to simulation; Triage agent works inside Slack, web and MCP where teams already operate; Free starting tier and no credit card required to begin

**Limitations:** Aimed at teams already running agents in production, which is a narrowing audience; Advanced simulation and enterprise capabilities sit behind paid and enterprise plans; Fast-moving product surface means some features may shift or be labelled beta
