# Preuve AI vs doing manual research

> **TL;DR:** Manual research means doing the legwork yourself: secondary reading, competitor teardowns, market sizing, and 20-30 customer interviews over 2-6 weeks (roughly 30-50 hours of skilled desk work plus interview time). Preuve AI runs the desk-research baseline in minutes by scanning 50+ live sources with 10 parallel AI agents, links every claim to its source, and surfaces 3 pivot recommendations on the $29 Founder tier. It does not replace primary interviews. The strongest workflow is complementary: Preuve AI for the fast, auditable baseline, then your own interviews for the primary signal a database cannot surface.

## What doing manual research actually involves

Done properly, manual validation is five stages. The desk-research stages take 30-50 hours of skilled work; the interviews take calendar time you cannot compress.

| # | Stage | What it involves | Time |
| --- | --- | --- | --- |
| 1 | Secondary research | Read reports, news, and forum threads to understand the space before you talk to anyone. | 10+ hours |
| 2 | Competitor teardown | Find competitors, log pricing, read G2 and Reddit reviews, map feature gaps and funding. | 15-25 hours |
| 3 | Market sizing (TAM/SAM/SOM) | Pull population and spend data, build a bottom-up model, sanity-check the assumptions. | 5-10 hours |
| 4 | Customer discovery | Recruit and run 20-30 interviews. Patterns only emerge once you reach that range. | 2-4 weeks |
| 5 | Synthesis + verdict | Reconcile everything into a go / no-go call and decide what to change if the answer is no. | 5-8 hours |

Skills it assumes: reading and weighing sources, bottom-up market modeling, and running interviews without leading the witness. Most founders are strong in one of these, rarely all of them.

## How Preuve AI produces the same baseline

1. **You enter your idea** - one or two sentences describing what you want to build and who it is for.
2. **10 agents scan 50+ sources** - parallel AI agents pull funding, demand signals, competitors, and reviews from live sources.
3. **You get a scored report** - viability score, competitor map, market sizing, risks, and pivots, with each figure linked to its source.

No human reads your idea to score it. The scan runs on your own submission and produces the report you read.

## Source coverage: by hand vs with Preuve AI

| Category | By hand | With Preuve AI |
| --- | --- | --- |
| Funding & competitors | Search Crunchbase, Google each name one by one | Crunchbase funding and competitor set, auto-mapped |
| Demand signals | Eyeball Google Trends, scroll Reddit threads | Google Trends plus Reddit and forum pain points |
| Competitor launches | Browse Product Hunt by hand | Product Hunt launch history |
| Competitor weaknesses | Read dozens of G2 and Capterra reviews | G2 and review-site weakness extraction |
| Market sizing | Statista plus a spreadsheet model | Bottom-up TAM/SAM/SOM with source links |
| News & press | Repeated manual searches | Live news and press feeds |

Preuve AI scans 50+ live sources via 10 parallel agents. The categories above are a representative slice, not the full list.

## Reproducibility: can you audit the sources?

Every data point in a Preuve report links back to where it came from. Funding figures, competitor pricing, demand signals: open the link and check the origin before you act on it. A generic AI chat hands you a confident number with no way to verify it; a source-linked report lets you audit any claim, which is exactly what you would do with your own notes.

## Side by side: effort, time, and fit

| Dimension | Manual research | Preuve AI |
| --- | --- | --- |
| Time to insight | 2-6 weeks | Under 5 minutes |
| Hands-on effort | 30-50 hours of skilled work | Enter your idea, read the report |
| Skills needed | Research, modeling, interviewing | None |
| Out-of-pocket cost | Free, but your time | $29 one-time |
| Source breadth | Whatever you reach by hand | 50+ live sources via 10 agents |
| Source auditability | Your own notes | Every claim links to its origin |
| Primary signal (interviews) | Yes, first-hand | No, do these after |
| Pivot recommendations | You spot them yourself | 3 on the Founder tier |

Best fit: run Preuve AI first for an auditable baseline in minutes, then invest your own hours in the customer interviews that AI cannot do.

## Pivot recommendations: by hand vs from the data

Manually, finding a pivot means spotting an underserved adjacent segment yourself across all your research. On the Founder tier ($29), Preuve AI returns 3 pivot recommendations drawn from gaps in the competitive and demand data, each tied to the sources behind it. The free scan includes the score, key risks, and 2 competitor previews, but not the pivots.

## Where manual research still wins

- **Primary interviews** - talking to 20-30 potential users surfaces objections and willingness-to-pay signals no database holds. This is the single highest-value thing manual research gives you, and it is the thing Preuve AI tells you to go do.
- **Deep niche judgment** - if you already have years in a market, your pattern recognition beats any scan on the edge cases. Use the baseline to check your blind spots, not to overrule first-hand expertise.

Building something nobody wants is still the most-cited reason startups fail, around 42% in CB Insights post-mortems. Neither method removes that risk by itself, but running them together is what brings it down.

## FAQ

### How does Preuve AI compare to doing manual research for startup idea analysis and pivot recommendations?

Manual research means doing the legwork yourself: secondary reading, competitor teardowns, market sizing, and 20-30 customer interviews over 2-6 weeks. Preuve AI runs the desk-research baseline in minutes by scanning 50+ live sources with 10 parallel AI agents, links every claim to its source, and surfaces 3 pivot recommendations on the $29 Founder tier. It does not replace primary interviews, so the strongest workflow is Preuve for the fast auditable baseline, then your own interviews.

### How long does manual market research take for a startup?

A thorough manual pass runs 2-6 weeks: roughly 30-50 hours of desk research (secondary reading, competitor teardown, TAM/SAM/SOM modeling) plus 2-4 weeks to recruit and run 20-30 customer interviews. Preuve AI compresses the desk-research portion to under 5 minutes; the interviews still take human time.

### Is manual research still worth doing if I use an AI tool?

Yes, for the part AI cannot do: talking to real customers. Preuve AI handles the data gathering and structuring across 50+ sources so you skip the 30-50 hours of desk work. Manual customer interviews still teach you things no database surfaces, so run them after the baseline says the idea is worth pursuing.

### Can Preuve AI give pivot recommendations like a manual analysis would?

On the Founder tier ($29), Preuve AI returns 3 pivot recommendations drawn from gaps in the competitive and demand data, each tied to the sources behind it. Manually, finding a pivot means spotting an underserved adjacent segment yourself across all your research. The free scan includes the score, key risks, and 2 competitor previews, but not the pivots.

### Can I verify Preuve AI the way I would check my own research?

Yes. Every data point in a Preuve report links back to where it came from, so you can open the source and check it like a citation in your own notes. That traceability is the main thing an opaque AI answer lacks: you are not asked to trust a number, you are shown its origin.
