Short answer: AI is used in finance to read and summarise documents, detect fraud and money laundering, score credit risk, optimise trading and portfolios, draft reports, and, on the deal side, screen targets and speed up due diligence. Adoption is now the norm rather than the experiment. The open questions are about control, not capability: who checks the output, and what happens when it is wrong.
How widely is AI used in finance?
The Bank of England and FCA survey found that 75% of UK financial firms were already using AI, with a further 10% planning to within three years. The same report found that a third of all AI use cases were third-party implementations, and that foundation models made up 17% of use cases.

Inside the finance function itself, Gartner found 59% of finance teams using AI in 2025, against 58% in 2024 and 37% in 2023, in a survey of 183 CFOs and senior finance leaders. Growth has flattened, and data quality and skills are the barriers named. Gartner’s own page blocked automated access, so this is cited from CFO Dive’s report of it.

Read those two together. Adoption jumped quickly, then plateaued once the easy wins were taken, and what separates firms now is whether their data and processes are clean enough for the tools to work.

The main uses of AI in finance, what it does in each, and where a person still decides.
USE
Fraud and AML
- WHAT THE AI DOES
- Flags unusual transactions and patterns across large volumes
- WHERE A PERSON DECIDES
- Whether a flagged case is real, and whether to file a report
USE
Credit and underwriting
- WHAT THE AI DOES
- Scores applicants, including from cash-flow data
- WHERE A PERSON DECIDES
- Policy thresholds, exceptions, and explaining a refusal
USE
Trading and portfolios
- WHAT THE AI DOES
- Signals, execution and portfolio optimisation
- WHERE A PERSON DECIDES
- Risk limits and strategy
USE
Reporting and FP&A
- WHAT THE AI DOES
- Extracts figures from documents, drafts variance commentary
- WHERE A PERSON DECIDES
- What the numbers mean and what goes to the board
USE
Deal screening and diligence
- WHAT THE AI DOES
- Reads CIMs and data rooms, extracts financials, drafts summaries
- WHERE A PERSON DECIDES
- Whether to pursue the deal, and the price

Fraud detection and anti-money-laundering
Pattern detection over huge transaction volumes is what machine learning does best, which is why fraud and AML sit among the earliest and most established uses. The Bank of England survey lists them among the highest perceived current benefits of AI in financial services. The catch is false positives: a model that flags everything is a model people stop reading.
Credit scoring and underwriting
The appeal is reaching people a traditional score cannot see.
A FICO pilot using alternative data found that as many as half of applicants who had no score received one of at least 620, a common underwriting threshold. The same briefing notes more than 45 million US consumers lack the history for a credit report or score. The figures are from 2023 or earlier.

Reporting, FP&A and document extraction
Most of a finance team’s week is moving numbers out of documents and into models. This is the least dramatic use and the one with the clearest payoff, because the task is bounded and the answer can be checked against the page it came from.
FINRA’s 2026 oversight report names summarisation and information extraction from unstructured documents as the leading generative AI use case among member firms.

AI in private equity and M&A
Deal work is document work: a CIM, a set of financials, a data room. That makes it a natural fit, and the surveys show it.
Deloitte’s survey of 1,000 senior corporate and private equity leaders reported that 86% had integrated generative AI into M&A workflows. By stage, 40% used it for strategy and market assessment, and 35% each for target screening and due diligence. 67% named data security as a leading concern.

For a large firm with an analyst bench, AI is an accelerator. For a team of one to three with no analyst, it is closer to the difference between reading the CIMs and not reading them. A principal who sees twenty inbound deals a week either triages by gut or triages by numbers, and pulling three years of financials out of a PDF used to be an evening.
A workable first-pass workflow for a small deal team
- Extract, do not conclude. Have the tool pull revenue, EBITDA, margins and add-backs from the CIM into a table, each figure linked to its source page.
- Screen against a written mandate. Size, sector, geography and margin thresholds turn triage from a mood into a filter.
- Check the numbers that matter. Spot-check the extraction on the two or three figures the decision rests on, against the page.
- Write the conclusion yourself. Let a memo builder assemble the structure, then put your judgement in it.
The useful question is never whether the AI is smart. It is whether you can see where each number came from.
The risks, and what regulators are saying
FINRA defines hallucinations as “instances where the model generates information that is inaccurate or misleading, yet is presented as factual information”, and flags AI agents acting autonomously without human validation and approval as a risk.

In April 2026 the Federal Reserve issued SR 26-2, revised model risk management guidance that supersedes and replaces SR 11-7 from 2011. It emphasises a risk-based approach and is aimed mainly at banks with more than $30 billion in assets. Older articles that cite SR 11-7 as current are out of date.

The SEC charged two investment advisers, Delphia and Global Predictions, for false claims about their use of AI, with penalties of $225,000 and $175,000. Chair Gensler called it “AI washing”. If you say you use AI, you have to be doing it.

Under the EU AI Act, systems used to evaluate the creditworthiness of natural persons or set their credit score are classed as high-risk, with an exception for systems used to detect financial fraud.

Every one of these points the same way: keep a person accountable, keep the source visible, and do not claim more than the tool does.
What AI in finance cannot do
- Tell you what a number means for your deal. It can extract EBITDA. It does not know that the add-backs are the owner’s house.
- Verify itself. Extraction can misread a table. Trace the figures that drive the decision.
- Carry accountability. The person who signs the LOI owns the answer.
Where Avise fits
Avise is deal flow software for small deal teams and search funds. It reads a CIM and extracts the financials, keeps every deal in one place with a data room and a memo builder, and costs $249 a month for the whole firm, not per seat. It does the first pass so you do the thinking; the figures link back to the pages they came from. See the product page or the pricing, and our comparison with the spreadsheet you already have.
