Open Text Comparison ToolStep-by-step instructions
- Paste the original and changed versions into the two text boxes.
- Choose line or word comparison; spaces and capitalization remain significant.
- Compare, review green additions and red removals, and download the report.
Processing limits
50,000 characters per side; 2,500 tokens per side; two million comparison cells.
Important details
Comparison is exact and case-sensitive. Word mode includes whitespace tokens, so spacing changes are visible.
The size guard depends on both inputs, not only character count. Split a long document into sections if the comparison is rejected.
HTML, scripts and markup are shown as plain text, never executed. Reports do not modify either original document.
Privacy and usage
Content stays in your browser. Helphonic receives only access checks and non-content operation metadata. Download or copy results before leaving; there is no account storage. Usage is initially unlimited for all audiences but remains configurable by an administrator.
Processing and privacy
Files and entered content are processed on your device in this browser tab. File contents and results are not uploaded to Helphonic or sent to analytics. The page still contacts Helphonic to load its tools, check access and confirm non-content usage information. Work is not saved to your account; download or copy results before leaving or reloading the page.
Access and current limits
Check the tool page for current access, remaining usage and per-operation limits. File count, per-file size, total size and page limits can depend on your access and can change. Device and processor safety limits still apply when usage is unlimited. A paid pass does not necessarily increase every processing limit.
One successful export counts as one operation. Previewing and editing do not use an operation. Daily allowances reset at 00:00 UTC. Downloads of an already-created result do not count again.
If an operation cannot finish
Use a current browser and smaller inputs if the tab runs out of memory. Some tools download a local processing library or model on first use, so an internet connection is needed even though your content stays on the device.
If the tool reports that access or limits changed, review the current policy and run it again. If usage confirmation is uncertain after an interrupted connection, a retry can count as another operation. Download completed work before reloading; this site does not keep a recovery copy.
Check the current limits
Allowances and per-operation limits can change. The Text Comparison Tool page shows the policy that applies to you. Per-operation safety limits still apply when usage is unlimited. See access passes if a tool or extra usage requires paid access.
