As of 13 August 2026, AI can only partly predict which leads will convert.
This still needs a person who signs their name to it.

How to actually do it
- Open your CRM and export anonymised historical leads together with the outcome field, creation date and the fields that were available before a sales decision was made.
- Write down what counts as conversion, the conversion window, and which current leads are still open for follow-up.
- Remove names, personal contact details and fields created after conversion, then fix inconsistent labels and remove duplicate rows in a spreadsheet.
- Split the cleaned file into historical records and current leads, keeping the field names and definitions identical in both tables.
- Paste the field definitions, historical data, current leads and sales context into the prompt, then ask the model to produce the priority bands and recommended next actions.
- Ask a colleague who understands the CRM to check the exclusions, assumptions and sample rankings against the original records before anyone changes their outreach order.
- After the agreed conversion window, add the real outcomes to the current-lead table and compare them with the predicted priority bands before adopting the method again.
Prompt
You are helping me prioritise sales leads, not make certain predictions. I will paste an anonymised table of historical lead records below. Task: 1. Define the conversion outcome using this exact field: [conversion field and value that counts as converted]. 2. Exclude any field that would only become known after the conversion decision, including later-stage activity, closed-won information and post-sale notes. 3. Identify missing values, inconsistent labels, duplicate records and possible data leakage before ranking anything. 4. Use the historical records to create a transparent lead-priority score for the current leads. Explain which observed fields contribute to the score and do not claim that any field causes conversion. 5. Return a table with lead ID, priority band, evidence used, missing information and a recommended next action. Do not invent values or fill gaps with guesses. 6. Separate the historical records used to learn patterns from the current leads being ranked. Suggest a simple time-based test using later outcomes, and state what result would count as useful without pretending the test proves future performance. 7. Flag groups that may be disadvantaged by the available data, and list the checks a sales manager should complete before using the ranking. 8. State clearly that this is a prioritisation aid rather than a guarantee of conversion. Data fields and definitions: [Paste the field list and definitions here] Historical lead data: [Paste anonymised historical records here] Current leads to rank: [Paste anonymised current lead records here] Business context: - Sales process: [brief description] - Conversion window: [for example, within the agreed sales period] - Capacity available for follow-up: [describe the team capacity] - Lead groups or territories that must be treated separately: [list them or write none] Use plain English and show your assumptions. Ask for clarification instead of guessing.

What it gets wrong
- AI cannot create reliable signal when your CRM outcomes are incomplete, inconsistently recorded or too sparse.
- AI cannot know whether a lead looks promising because of genuine buying intent or because the data contains leakage from a later sales stage.
- AI cannot choose the right definition of a valuable conversion when sales cycles, deal sizes and strategic accounts differ.
- AI cannot carry the commercial responsibility for ignoring a lead or assigning a salesperson's time elsewhere.
- AI cannot verify predictive quality cheaply without waiting for outcomes and understanding basic testing and bias risks.
What caps this at PARTLY: verification cost, judgement under ambiguity and stakes of error.
How we scored this
Five axes, each scored nought to two by hand: ten means AI carries the task cleanly, and the thresholds that turn a total into YES, PARTLY or NO are published in the methodology. Each axis name links to its definition.
| Axis | Score (0–2) |
|---|---|
| Output | 2 |
| Inputs | 1 |
| Verification | 1 |
| Liability | 1 |
| Effort delta | 2 |
| Total | 7 / 10 |

FAQ
- Can ChatGPT predict which sales leads will convert?
- Partly. It can rank leads from a clean CRM export and explain the signals it used, but it cannot guarantee conversion or repair weak outcome data. A colleague should check the inputs and the ranking before it changes your sales priorities.
- How accurate is AI lead scoring?
- There is no honest accuracy figure without your historical outcomes, sales process and a proper test on later leads. Test the ranking against outcomes that were not used to create it, and check for data leakage before treating it as useful.
- What data does AI need to predict lead conversion?
- It needs historical leads with a clearly defined conversion outcome, dates, and information available before the conversion decision. It also needs current leads with comparable fields, while excluding personal data and later-stage information that would leak the answer.
- Should I trust an AI lead score?
- Use it as a prioritisation aid, not as a decision that replaces sales judgement. Check the records behind the score, compare later outcomes by priority band, and keep a human review for important accounts or unusual cases.
