Research & Synthesis Agent
Web and internal source aggregation with structured summaries and citations
What a research agent actually does
You define a research task — "produce a 2-page competitive intel brief on company X covering pricing, product roadmap, team, funding, and customer reviews from public sources." The agent runs the research: queries search engines, fetches pages, extracts relevant chunks, dedupes, summarises, structures into your output format, and emits a dossier with inline citations.
You can run it interactively (a salesperson before a call) or on a cadence (50 prospect briefs every Monday morning).
The defining features versus a generic LLM with browsing:
- Defined task with structured output schema, not free-form chat
- Source dedup so 12 articles about the same news event don't all influence the summary
- Citation map so every claim is traceable to a source
- Date awareness so stale claims don't override recent ones
- Repeatable — the same input produces a comparable output, run after run
Anatomy of a working pipeline
[Research task with schema]
↓
[Query expansion: 5–15 sub-queries from the task]
↓
[Parallel search across sources: Google, Bing, internal KB, structured APIs]
↓
[Headless browser fetch (Browserbase / Firecrawl) for top results]
↓
[Chunk + embed + dedup across sources]
↓
[Long-context synthesis (Claude) with all evidence in window]
↓
[Structured output (Zod schema) with inline citation IDs]
↓
[Citation map: every claim → list of source URLs + dates]
↓
[Output to destination (CRM, Notion, email, dashboard)]

Use cases we have shipped
- Sales prospect briefs. Salesperson opens HubSpot contact → "Generate brief" button → 2-page brief on the contact's company appears within 90 seconds, attached to the record. Inline citations link to source articles.
- Competitive intel monitoring. Daily scheduled run for ~30 competitors; agent surfaces changes (new pricing tier, hire announcement, product launch) in a Slack digest.
- Due-diligence dossiers. Investment team requests a brief on a target company; agent produces 5–10 page dossier covering market, product, team, funding history, customer reviews, regulatory exposure, with cited sources.
- Customer-success research. Before a QBR, agent compiles a one-pager on the customer's recent news, hiring, expansion signals.
Stack we tend to reach for
| Layer | Default |
|---|---|
| Web fetch | Browserbase (managed headless browser) / Firecrawl |
| Search APIs | Google CSE / Bing Search API / Tavily |
| Internal knowledge | pgvector / Pinecone over your docs |
| Synthesis model | Claude Sonnet 4.6 (1M+ context = whole-dossier reasoning) |
| Orchestration | LangGraph for multi-step research |
| Output schema | Zod |
| Citation graph | Custom — store as JSONB in Postgres |
| Cadence | Cloud Scheduler / Vercel Cron |
| Observability | Langfuse |
What makes a research agent "production-grade"
- Schema-driven output. Not free-form text. The output format is defined upfront and validated.
- Source dedup. Cosine similarity between chunks; chunks above threshold collapse into one with multiple sources.
- Date weighting. Recent sources outweigh older sources for time-sensitive claims.
- Citation map. Every claim has at least one source attached. No source = no claim.
- Fail-safe. If the agent cannot find enough sources or hits low confidence, it flags the section instead of confidently fabricating.
- Auditable. The full chain — query, search results, fetched pages, chunks selected, prompt, output — is logged and replayable.
Cost and timeline
| Scope | Investment |
|---|---|
| Single research workflow (one task type, one output destination) | €15,000–30,000 |
| Multi-workflow research platform (3–5 task types) | €30,000–70,000 |
| Enterprise research platform with multiple data sources and outputs | €70,000–150,000 |
| Retainer (ongoing tuning, new sources, new schemas) | from €1,500/month |
Pass-through costs: ~€0.20–€3 per dossier depending on depth, plus Browserbase / search API costs.
Where it pairs
Research agents commonly chain with:
- Workflow orchestrators that decide what to research and what to do with the output (route to a CRM, email a digest, file a ticket).
- Conversational agents that let users query the research corpus interactively after it's been built.
- Document processing agents when the research outputs themselves need extraction (e.g. extracting structured pricing tables from competitor sites).
If you have a research workflow your team currently does manually, drop us a note. One paragraph is enough.

Custom agents that read documents, hold conversations, take phone calls, and execute multi-step workflows — wired into the systems you already run.
ChatGPT API vs Claude API vs Gemini: which to pick (2026)
Claude Sonnet 4.6/4.7 is our default for production agents — most reliable tool calling, best structured output, strong reasoning. GPT-4o wins for voice (Realtime is best-in-class) and the largest ecosystem. Gemini 2.5/2.0 wins for long-context, vision-heavy document work, and cost-sensitive volume workloads. Pick per task; abstract behind a provider interface.
RAG done right: the patterns that survive production
Production RAG is engineering, not magic. The patterns that survive: hybrid retrieval (vector + BM25), rerank top-k with a cross-encoder, metadata filtering, source dating, citation rendering, sampled human review. Without these, your retrieval is good in the demo and broken in production.
The AI Development playbook: how we ship agents in 6 weeks
We ship production AI agents in 6 weeks by being opinionated about tools, refusing to skip discovery, building evals from day one, and treating code agents as a force multiplier. This is the playbook — what we use, what we refuse, and why it lands consistently.
