Consultants sell time and thinking. What takes time without creating direct value: documentary research, formatting deliverables, preparing slides. AI compresses these phases. What takes time and creates value: understanding the client's problem, strategic framing, the recommendation. AI does not replace that. In practice, research is the first visible transformation. Perplexity replaces half a day of documentary research with 20 minutes of sourced queries. Claude ingests a 150-page report and extracts the 5 critical points for a synthesis note. For repetitive market analyses at the start of a mission, the gain is substantial. For deliverables, Gamma generates a first deck draft from a structured outline in minutes. Quality is sufficient for internal presentations or first client iterations. For final billable deliverables, the expected finishing level is higher and requires manual design work. Julius AI lets you analyze client data files without going through an external data analyst. Confidentiality is central. Consulting missions involve often sensitive data: revenues, headcounts, strategic plans, M&A files. Sending this data to Claude or ChatGPT without checking enterprise terms is a real risk. Most large firms have internal AI usage policies: respect them before adopting any tool.
The Joute stack for consultants
This is the combination we recommend for a solo consultant or small firm looking to compress research and formatting phases, according to The Jouster.
How to choose an AI tool as a consultant
Research, deliverables, confidentiality: the three axes that structure a consultant's tool choice.
Research and monitoring
Perplexity Pro offers the best value for real-time sourced research. For academic research and deep market studies, Consensus and Elicit source directly from scientific journals. For ongoing competitive monitoring, combining them with Google Alerts remains more effective.
Long document synthesis
Claude excels on long documents thanks to its context window (200,000 tokens). An annual report, a due diligence file, a sector study: paste the PDF and ask questions. ChatGPT with Advanced Data Analysis is better for complex Excel files.
Deliverables and slides
Gamma for fast drafts and internal presentations. Beautiful.ai for more polished decks with consistent design. For final client-billed deliverables, finishing work remains manual. AI handles content, the consultant handles design and storytelling.
Client data confidentiality
Mandatory to check enterprise terms before sending client data to an LLM. Claude for Enterprise and ChatGPT Enterprise guarantee non-use of data for training. Some firms have on-premise versions. Never send pseudonymizable data without having done so.

Frequently asked questions from consultants about AI
Can AI replace documentary research on a mission?+
For first-level research, yes. Perplexity reduces half a day of monitoring to 20 minutes of sourced queries. For primary research (interviews, surveys, proprietary data) and highly specialized analyses, no. AI compresses the documentary phase, it does not replace analytical thinking.
Which tool for analyzing complex Excel files on a mission?+
Julius AI for natural language analysis with chart generation. ChatGPT Advanced Data Analysis for data transformations and Python scripts. Claude for interpreting results and drafting the analysis note. All three are complementary depending on the stage.
Is it risky to use ChatGPT or Claude with client data?+
Yes on consumer tiers. That data may be used for training under the terms of service. Enterprise versions (Claude for Enterprise, ChatGPT Enterprise) guarantee non-use for training. Also check the firm's internal policy before any use.
Does Gamma replace McKinsey-style PowerPoint?+
Not for final deliverables. Gamma is excellent for drafts and rapid client iterations. For a final deliverable billed at 50,000 euros, the expected finishing level requires manual work in PowerPoint or Figma. Gamma accelerates the structuring phase, not the finishing phase.
How to use AI for client interviews and stakeholder conversations?+
Fireflies or Otter to transcribe automatically. Claude to analyze the transcript and extract key verbatims, friction points, and opportunities. What used to take a day of qualitative analysis takes 30 minutes. The value is in interpretation, which AI helps structure but the consultant validates.
