# Deck versions and founder corrections

> A new deck becomes the next version on the deal, and earlier versions keep their citations. Founder corrections sit next to the facts read from the deck.

## Key takeaways

- Every upload becomes the next version on the deal, such as Deck v2. Earlier versions stay, with their analysis and citations.
- The brief and deck quality come from the newest version that finished its analysis, so a failed upload never hides the last good one.
- Facts from a newer deck replace the older deck's facts for the same item. Founder corrections stay.
- A founder's correction never overwrites the original. You see both, side by side.

A deal can have several decks. Each upload becomes the next version, **Deck v1**, **Deck v2** and so on, and goes through its own scan and analysis. Earlier versions stay, and their citations keep pointing at the version they came from. When a founder corrects a fact read from their deck, you see the correction next to the original.

## See every version

Open the deal's **Files** tab. **Deck versions** lists each one, newest first:

- **Deck v3**, with **Latest** on the newest
- the file name, size, who uploaded it (**Founder, through the portal**, or **Your team** with the person's name) and when, in your fund's time zone
- its analysis status and **Deck quality**
- **Open**, which shows that version on the **Evidence** tab

## Upload a new version

Founders can send a new version themselves from their workspace (**Upload a new deck version**) until you send your decision; it shows as **Founder, through the portal**. To add one yourself:

1. On **Files**, click **Upload new version**.
2. In **Upload deck v3**, click **Choose the deck file**, or drop the file. PDF or PowerPoint (.pptx), up to 50 MB.
3. Click **Upload**. To stop, click **Cancel upload**.

You see "Deck v3 uploaded. Scanning and analysis have started." The upload also appears on the **Activity** tab.

Admins, Partners and the Analyst who owns the deal can upload.

## What a new version changes

| Where | What you see |
|---|---|
| **Brief** and **Deck quality** | The newest version that finished its analysis. If it's older than the latest upload, the brief says **From deck v2** |
| **Evidence** | The newest version whose slides can be shown. Pick another under **Deck version**; the list marks **(latest)** and any version still processing |
| Citations | Each **Slide** chip opens the version it came from. Chips from an older version show it, such as **v1** |
| Facts | The newer deck's facts replace the older deck's facts for the same item, such as revenue. Founder corrections stay |
| Claims | Claims from every version stay, each cited to its own version |

If you upload the exact same file again, the earlier analysis is reused.

## Founder corrections

After applying, founders see the company facts read from their deck in their workspace, and can correct any of them. See [Correct what was read from your deck](/help/applying/correcting-your-details) for what they see.

Founders can correct facts until you send your decision message (or they withdraw); then the list is read only for them. A correction never changes the original. On **Evidence**, the fact shows:

- the original, in a lilac **AI suggestion** box with its **Slide** chip, crossed out
- the founder's value beside it, under **Founder correction**

The side sheet's **Top facts** shows the founder's value with "(founder correction)". If the founder corrects the same fact again, you see their latest correction.

## Frequently asked questions

### Can I delete an older version?
No. Versions stay, so every citation keeps resolving to the slide it came from.

### Why doesn't the latest version show on Evidence?
Its slides can't be shown until it has been scanned clean and read. Until then, **Evidence** shows the newest version that can be opened, and the job tracker above it shows the new version's progress.

### Can the founder upload a new deck themselves?
Yes. Before sending, they replace it freely in the draft. After sending, **Upload a new deck version** in their workspace adds the next version, until you send your decision or they withdraw. It goes through the same scan and analysis, and the earlier version keeps its citations.

### Can a founder correct facts after we decide?
No. Once a decision message is sent, or the founder withdraws, their corrections are read only. The corrections they sent before stay.
