Features / Research

Deep web research,
multiplied.

Seven search backends, hybrid fusion, hierarchical fan-out and cross-referencing — an answer assembled from the whole web, not the first page.

Capabilities

How Parallel researches the web

7 search backends

Linkup, Parallel.ai, Exa, Tavily, Serper, Brave, DuckDuckGo — with hybrid and smart modes and RRF ranking to fuse results.

Hierarchical fan-out

spawn_agent at any depth up to max_depth; batches of children run in parallel, background mode reports results as notifications.

Deep fetch & crawl

web_fetch, web_crawl and web_feed pull full pages, follow sitemaps and parse RSS at up to 1.1M items/s.

Structured parsing

parse_html (531k rows/s) and extract_json turn any document into structured data.

Browser & vision

Real Chrome via CDP when the page fights back; analyze_image for screenshots, charts and documents.

Code-aware research

code_symbols and repo_map map codebases; PDF extraction reads whitepapers and filings.

Comparison

Parallel vs. manual research

Manual

  • Hours per topic, one tab at a time
  • Single search engine, first-page bias
  • Copy-paste into spreadsheets
  • No verification, stale data
  • Nothing remembered next week

Parallel

  • Minutes per topic, parallel agents
  • 7 backends fused with RRF ranking
  • Structured findings + exports
  • Verified contacts, cross-referenced facts
  • Semantic memory carries knowledge forward

Under the hood

Multi-agent fan-out explained

1

Plan

LLM decomposes the query into sub-tasks; subtasks persist in SQLite.

2

Fan out

Coordinator spawns sub-agents (JoinSet or separate OS processes).

3

Collect

Budget-capped summaries flow back; context stays small.

4

Reflect

Goal Mode: an LLM judge checks the result against the goal and runs gap-filling rounds.

5

Synthesize

Findings merge into summary.md + findings/, absorbed into memory.

Agent roles

Five roles, one pipeline

Every agent runs a role-specific prompt on top of the same runtime. Roles can be overridden per deployment via [agent.role_models].

Coordinator

Decomposes the query into 2–5 sub-tasks, delegates, and synthesizes the final answer.

Researcher

Web search + OSINT / lead-gen workflows with source citation.

Analyst

Cross-references findings, spots patterns and contradictions, assigns confidence HIGH/MED/LOW.

Verifier

Adversarial fact-checking: VERIFIED / LIKELY / UNVERIFIED / CONTRADICTED.

Writer

Structures the report: Summary / Findings / Analysis / Sources / Gaps.

3-tier prompts

Stable / context / volatile prompt layers maximize prefix-cache hit rates across the fleet.

Use cases

Built for real business scenarios

Market & competitor scans

Track pricing, positioning and hiring across an industry — with diffs between runs.

Due diligence

Company facts, news, filings and key people into one verified dossier.

Lead research

Decision-makers at target companies, enriched and verified before outreach.

Tech scouting

Map repos, extract symbols, summarize documentation with code_symbols + repo_map.
