In 2024, the typical accounting firm regarded artificial intelligence as "an interesting technology." In 2026, AI is an operational part of the office — bookkeeping, categorization, client summaries, VAT (KDV) prep. Which tools are actually being used? Which are just marketing?
This article is a practical guide to the AI tools used in real accounting firms.
What tools are out there?
As of 2026, the main AI tools in use at Turkish accounting firms:
1. Claude (Anthropic)
Anthropic's Claude leads in financial use cases. Explainable, accurate, auditable. Available through the web interface (claude.ai) and the API.
Practical uses:
- Drafting automatic replies to client questions
- Verifying VAT calculations
- Writing anomaly reason chains
More detail: Anthropic Claude's finance use cases — the 2026 report.
2. ChatGPT (OpenAI)
ChatGPT is the most widely adopted AI tool. Good Turkish support, and the free tier is genuinely useful.
Practical uses:
- General research (regulatory changes)
- Drafting emails
- Generating Excel formulas
More detail: OpenAI GPT-5 and autonomous accounting agents.
3. Cursor (a software IDE)
Cursor is a code editor — and yet it earns its keep at accounting firms. Use it to write Excel macros, Python scripts, and automation code.
Practical uses:
- Bank statement parsing scripts
- Generating Excel macros
- ERP automation code
4. Devin (Cognition Labs)
Devin AI is a fully autonomous software developer. For an accounting firm, it can handle internal process automation.

| Criterion | Claude | ChatGPT | Cursor | Devin | |---|---|---|---|---| | Financial accuracy | Very high | High | - | - | | Turkish support | Good | Very good | - | Moderate | | Cost/month | $20-25 | $20 | $20 | $500+ | | Learning curve for accountants | Low | Low | Moderate | High | | Explainability | Very high | Moderate | - | Moderate | | Usage frequency | Daily | Daily | Weekly | Monthly |

Which tools should you avoid?
Some AI tools are simply not a fit for an accounting firm:
- Anything promising to "automate your entire accounting" → insufficient regulatory knowledge
- "Black box" AI that offers no explanations → a problem at audit time
- Free tools that ship sensitive data to third parties → a KVKK (Turkish data protection law) violation
