"""

Instructions:
1. Fix spelling, grammar, punctuation and agreement.
2. Depending on the chosen level, improve clarity and flow without changing the meaning or the author's personal style.
3. Return the full corrected text.
4. Then, a table with the important changes: original → corrected → reason.
5. Separately flag (without changing them) ambiguous sentences or facts worth verifying.
6. Keep the regional variety and spelling conventions of the original (e.g. US or UK English) and do not add new content or opinions.How to use it
Choose “errors only” to keep the text almost untouched. For long documents, proofread section by section.
Usage example
Type: motivation letter · Level: errors and clarity.
Sample output
I only received the placeholder, not the text, so here's the format using a sample paragraph from a blog post:
Corrected text
When I started writing this blog, I wasn't sure what to say. Now, three years later, I know that what interests you most are the mistakes I made and how I fixed them.
Key changes
| Original | Corrected | Reason |
|---|---|---|
| When I start writing | When I started writing | Past tense to match the timeline |
| i wasnt sure | I wasn't sure | Capital I and apostrophe |
| now three years later | Now, three years later, | New sentence; commas around the aside |
| what interest you most is | what interests you most are | Subject–verb agreement |
Worth checking (left unchanged)
- "three years later": confirm it matches when the blog actually started.
- "what interests you most": if it's based on traffic data, say so; if it's a hunch, consider softening it…
