Solo consulting is a ruthlessly efficient test of productivity tools. When you are the sole revenue generator, business developer, project manager, finance function, and delivery team, there is no slack to absorb poor tool choices. Bad tools do not just waste time — they erode the margins of a one-person business.
After several years of running a consulting practice from multiple countries, here is the exact AI productivity stack that has survived the test of actual use.
The Principle: Tools That Multiply, Not Tools That Impress
I evaluate productivity tools by one measure: does this multiply my effective capacity, or does it just add complexity? Many AI tools look impressive in demos and create friction in practice. The ones below have passed the friction test.
Writing and Thinking: Claude 3.5 Sonnet
My primary AI tool for any knowledge work — strategy development, proposal writing, client communication drafts, article writing, and complex problem analysis.
Why Claude over ChatGPT for consulting work: the quality of reasoning in ambiguous situations is higher, the writing quality is closer to professional standard without extensive editing, and it handles nuanced multi-constraint problems more reliably.
My daily use cases:
- First-draft consultant proposals (paste brief + discovery notes → structured proposal outline)
- Stress-testing strategic recommendations before client presentation
- Email drafts for sensitive client situations
- Article and content drafts (I edit extensively, but the skeleton is AI-generated)
Cost: Claude Pro at £18/month. Pays for itself in the first hour of use each month.
Research: Perplexity Pro
Live web research with cited sources. Replaced most of my Google-based desk research workflow.
The key feature for professional use: inline citations. When I include market data or trend information in a client deliverable, I need to be able to trace it. Perplexity makes this fast.
My daily use cases:
- Market landscape research for new client sectors
- Competitive intelligence updates on specific companies
- Finding primary sources for statistics I need to cite
- Consumer sentiment research via Reddit focus mode
Cost: Perplexity Pro at approximately £16/month.
Operations and Pipeline: Notion AI
My central operational system — contacts, opportunities, projects, meeting notes, deliverables. Notion AI is embedded into this for document drafting, meeting summaries, and pipeline interrogation.
My daily use cases:
- Drafting agenda sections from bullet notes before meetings
- Summarising meeting notes into structured action item lists
- Weekly pipeline review: which relationships need attention?
- Onboarding documents for new client engagements
Cost: Notion AI add-on approximately £8/month.
Meetings: Otter.ai
Transcription and summarisation for client calls and internal planning sessions. I have tried multiple transcription tools — Otter.ai has the best accuracy for UK English in my testing.
The post-meeting summary feature, which identifies action items and key decisions automatically, saves approximately 30 minutes per meeting in follow-up documentation time.
Cost: Otter.ai Pro at approximately £12/month.
Image and Creative: Adobe Firefly
For any AI-generated visual content that goes into client-facing materials, Firefly is the only responsible choice for commercial work. Its content indemnity policy means that I am not exposing my clients to intellectual property risk.
My use cases:
- Presentation and proposal hero images
- Concept direction frames for creative brief discussions
- Social media graphic elements
Cost: Included in my Adobe Creative Cloud subscription.
International Payments: Wise (not strictly AI, but essential)
Wise is not an AI tool, but it is so essential to the financial infrastructure of solo consulting across multiple currencies that it belongs in this stack. Holding GBP, EUR, and USD in a single account, with near-real-time transfers at near-market rates, has saved me hundreds of pounds in conversion fees annually.
Cost: No monthly fee; transaction fees apply.
The Full Monthly Cost
| Tool | Monthly Cost |
|---|---|
| Claude Pro | ~£18 |
| Perplexity Pro | ~£16 |
| Notion AI | ~£8 |
| Otter.ai Pro | ~£12 |
| Adobe CC (with Firefly) | ~£55 |
| Total | ~£109/month |
At a consulting day rate, this stack pays for itself in under two hours of saved time per month. The actual saving is more like a full day.
What I Removed From the Stack
ChatGPT Plus — I subscribed for two years. The quality gap between Claude and GPT-4 for my specific use cases (nuanced writing, complex strategic reasoning) meant Claude won. I kept ChatGPT for Advanced Voice Mode specifically.
Jasper AI — Marketing copy tool. Produced generic output that required more editing than Claude-based drafts. Cancelled.
Zapier AI — Workflow automation with AI. Added complexity without proportionate value for my solo operation. Cancelled.
Grammarly Business — Useful but redundant when Claude is already producing clean prose. Cancelled.
FAQ
Q: Do you need all of these tools or can you start with one? A: If you are starting out, Claude alone covers the majority of consulting-related AI productivity gains. Add Perplexity next for research. The others are optimisations for specific workflows.
Q: Is there an all-in-one tool that replaces most of this stack? A: Not yet, in my experience. Tools that claim to do everything tend to do nothing exceptionally. Specialist tools for specific workflows outperform generalists.
Q: How much time do you actually save with this stack compared to pre-AI? A: I estimate 8 to 10 hours per week across research, documentation, writing, and administrative tasks. For a solo consultant, this is the equivalent of a significant part-time assistant.
Q: Does using AI tools affect client perception of your work quality? A: The clients who know I use these tools (which is most of them — I am transparent about it) consistently receive higher-quality, faster deliverables than before. No client has ever raised the use of AI tools as a concern. The standard of the work is what matters.
Q: What is the most important AI tool for a new consultant to invest in first? A: Claude, without hesitation. The improvement in proposal quality, communication quality, and thinking rigour is immediate and significant.
