Consulting firms don't have a research problem so much as a retrieval problem: insight gets read once, scattered across people and projects, and never resurfaces when the next client needs it. A firm-wide research stack should turn what your teams read into a shared, citable knowledge layer — without sending sensitive client material outside the EU. This list starts with Pith, then covers six established tools; each is honestly scoped, because the right stack usually combines two or three of them rather than betting on one.

1. 1

   Pith

   Visit site

   A reading-memory layer built for consultancies: people bookmark what they read, and Pith auto-builds a cited wiki and per-client briefings on top of it. Knowledge is shared per client, so the whole team inherits one researcher's reading. EU data residency (Frankfurt), with an MCP server so the same memory is reachable from AI tools.

   Good for: Firms that want what their consultants read to become durable, cited, per-client knowledge the whole team can reuse — with EU data residency.

   ⚠ Young and focused: it's a reading-memory and per-client wiki layer, not a broad licensed-content database or a general-purpose docs/intranet — pair it with where your documents already live.

2. 2

   Google NotebookLM

   Visit site

   An AI notebook that grounds its answers in sources you upload, with inline citations back to the exact passage. Strong for interrogating a defined set of documents — interview notes, reports, transcripts — and generating summaries or audio overviews.

   Good for: Quickly synthesising a fixed corpus of project documents with traceable citations, on a per-notebook basis.

   ⚠ Notebooks are siloed, not a shared firm-wide knowledge base, and it's a Google Cloud product — confirm data-handling and residency terms before putting client material in.

3. 3

   Perplexity

   Visit site

   An answer engine for live web research: ask a question, get a synthesised answer with citations to current sources. Fast for market scans, fact-checking and getting oriented in an unfamiliar topic.

   Good for: Open-web discovery and quick, cited first-pass research at the start of an engagement.

   ⚠ It researches the live web, not your firm's internal reading or client files — nothing it produces is retained as shared team memory unless you save it elsewhere.

4. 4

   Notion

   Visit site

   A flexible workspace for docs, wikis and databases. Many firms run their internal knowledge base, project spaces and research notes here, with AI search layered on top.

   Good for: A general-purpose, structured home for firm and project documentation that teams actually maintain.

   ⚠ It's a blank canvas — citations, per-client briefings and 'auto-built from what we read' don't happen on their own; you build and maintain the structure. Check hosting/residency for EU clients.

5. 5

   Confluence

   Visit site

   Atlassian's enterprise wiki for structured, permissioned documentation. Mature governance, spaces and access controls make it a common system of record at larger firms, especially alongside Jira.

   Good for: Firm-wide documentation that needs robust permissions, governance and IT-managed administration.

   ⚠ It's a manually maintained wiki, not a research tool — it won't summarise sources or build cited knowledge from your reading. A data-residency (EU) option exists on enterprise plans; verify for your tier.

6. 6

   Readwise

   Visit site

   A personal read-it-later and highlight system (Reader): save articles and documents, highlight, and resurface notes over time. Excellent for individual reading workflows and retaining what you read.

   Good for: Individual consultants who want to capture, highlight and remember what they read.

   ⚠ Built around the individual, not the firm — there's no shared per-client knowledge layer or cited team wiki, and it's a US-based service.

7. 7

   AlphaSense

   Visit site

   An enterprise market-intelligence platform with a large library of premium content — broker research, filings, earnings calls and an expert-interview network — plus AI search with traceable citations across that corpus and your own internal documents.

   Good for: Firms needing deep, licensed market and company intelligence with source attribution, typically for financial and corporate-strategy work.

   ⚠ Enterprise-priced and content-heavy; it's a premium-data and search product, not a lightweight layer for capturing and sharing what your team already reads day to day.
