CHAT EXPORT CHECKER
Paste or upload a copied ChatGPT conversation, Markdown export, HTML save, or JSON export. Get a confidence score for missing snippets, truncation, UI noise, and broken code blocks.
Checks your exported file, not your live ChatGPT account.
Optional, but useful when checking a long copied thread.
Not a guarantee. This score only describes the file you provided.
VERIFICATION REPORT
| Severity | Issue | Evidence | Suggested action |
|---|---|---|---|
| warning | Very short export | 898 characters found. | If this was a long chat, re-export or paste the full thread. |
| info | Code blocks detected | 1 code block(s) found. | Review code blocks manually because truncation there can be costly. |
FIRST PREVIEW
User: I need to build a small overseas website portfolio. The first goal is to choose one useful pain point and ship a tiny tool. Assistant: Start from a concrete user pain, not from a random keyword. Capture the user, scenario, desired result, current alternative, and why that alternative is weak. User: Here is the next site idea: a long AI chat export chec
LAST PREVIEW
s, first and last snippets, code fences, duplicate blocks, UI noise, and possible truncation. ```ts function archiveCheck(input: string) { return input.length > 1000; } ``` User: Make sure it is local only. I do not want to upload private chat logs. Assistant: Then the page should say: files stay in your browser, no login, no upload, confidence checker only.
This tool checks the exported file you provide. It can detect suspicious structure, missing expected snippets, broken code fences, duplicated blocks, and noisy copied interface text.
It cannot prove that the original live ChatGPT conversation was complete. Treat the result as a confidence check before archiving or migrating a long thread.
Use it before moving a long project thread to another AI tool, saving research notes to Markdown, archiving a client planning chat, or turning a copied conversation into documentation.
The safest workflow is to keep two backups: one raw export and one cleaned Markdown or text copy.
FAQ
No. The checker runs in your browser. The first version does not upload your pasted text or files.
No. It checks the file you provide. It does not log in, scrape ChatGPT, or use the OpenAI API.
No. It gives a confidence score and warnings. You should still compare the first and last previews manually.
Plain text and Markdown are easiest to inspect. HTML and JSON are supported for a first-pass check.
