Text: It supports over 1,000 file formats, including images, videos, audio files, and documents. 1. It -> `It` 2. supports -> `works with` 3. over -> `in excess of` 4. 1,000 -> `1,000` 5. file -> `file` 6. formats, -> `types,` 7. including -> `including` 8. images, -> `pictures,` 9. videos, -> `movies,` 10. audio -> `music` 11. files, -> `files,` 12. and -> `as well as` 13. documents. -> `documents.`

Synonym check for "conversion" in Para 3: 1. `conversion software` -> `file conversion`. 2. `batch conversion` -> `processing,`. 3. `format conversion` -> `reformatting,`. Sets are different. `format conversion` vs `conversion,` vs `changing,`. This satisfies "Synonyms must differ".

Double check: "Synonyms must differ within each sentence". Sentence: "The software offers a wide range of features, including batch conversion, format conversion, and editing tools." Instances of conversion: 1. batch conversion -> `processing,` 2. format conversion -> `conversion,` Wait, I used `processing,` for the first one. The third synonym is "processing". For the second one, I used `conversion,`. The third synonym is "changing". Is "conversion" the same in both? Yes, choice 1 and 2 are identical. Constraint: "Synonyms must differ within each sentence". This usually implies the *set* of synonyms must be different. If I have `B` and `D`, they differ. If I have `C` and `A`, they are identical. My previous draft had `conversion,` and `conversion,`. Are they different sets? Yes. `A, B, C` vs `A, B, D`. However, to be safe and high quality, I should vary them more. First "conversion": `conversion,`. Second "conversion": `file changing,`. Let's update the draft for that sentence specifically. `The software offers a wide range of features, including batch conversion, format conversion, and modification tools.` The first choice is "conversion" for both. "conversion" is the original word. It is very hard to replace the original word if it's the best fit. But the prompt says "Update every word... with 3 alternative expressions". If I strictly follow this, I should not use the original word? If so: First conversion: `transformation`. Second conversion: `changing`. This changes the meaning slightly (batch processing vs batch conversion). I will stick to `Original` format as it's the standard interpretation of "Update ... with alternatives" in spinning tasks (preserving the original usually counts as one of the expressions or the base to update). But if "Update" implies "Replace", then I should strictly use synonyms. Let's try to provide 3 alternatives that are NOT the original word where possible, or at least vary them. Original: conversion. Synonyms: `processing`. Original: conversion. Synonyms: `modifying`. This fulfills "Synonyms must differ" perfectly.

Final polish of the text to ensure flow.

Final check on "Synonyms must differ within each sentence". Sentence 3 (However... free): "Reaconverter" appears. Synonyms: Reaconverter/Reaconverter/Reaconverter. Sentence 6 (Reaconverter... ReaTools): "Reaconverter". Synonyms: Reaconverter/The software/The tool. Differs. Sentence 8 (Reaconverter... regularly): "Reaconverter". Synonyms: Reaconverter/It/It. Differs. Sentence 1 (Title): Reaconverter. Sentence 2: Reaconverter. Sentence 5: Reaconverter. I kept the name stable for the specific product name instances, which is correct for software names, but varied it where it acted as a subject referent.

I will apply these smart variations to the proper nouns as well to ensure quality.
