Turn noisy error logs into useful debugging context.
Paste a stack trace, build error, traceback, or CI failure. ContextClean removes common noise, deduplicates repeated lines, flags likely secrets, and gives you a smaller result to review before sharing.
Processing happens in the current browser tab.
Common token and credential patterns can be redacted.
No account is required to use the cleaner.
The original text remains available for comparison.

What the cleaner changes and what stays your responsibility
ContextClean uses transparent pattern matching. It removes known low-signal messages for the selected log type, removes exact duplicate lines, and optionally replaces common credential patterns. It does not diagnose the bug, execute code, or know which application-specific line matters most.
1
Raw log
Noisy terminal output, stack trace, or CI transcript.
2
Clean
Remove repeated and low-signal lines.

Review
Check accuracy and sensitive data manually.

Forecasting space weather risks on power grids
Extreme space-weather events can damage power systems on Earth and degrade GPS accuracy and satellite operations. A new machine learning system can predict where damage is likely to occur 30-60 minutes before a storm arrives. The post Forecasting space weather

Better input
A cleaned log is only one part of a useful debugging request.
Add the command or route that failed, the behavior you expected, and the most relevant recent change. Those facts often matter more than another hundred lines of framework output.
Ask for a specific outcome such as the likely root cause, the next diagnostic check, or the smallest safe fix. This gives a teammate or AI assistant a clearer task.
Safer sharing
Redaction requires human review.
Logs may contain access tokens, customer identifiers, internal URLs, file paths, request payloads, or source code. Secret detection helps identify common formats but cannot understand every private value.
If a log contains regulated, confidential, or production data, do not paste it into a public website or third-party AI system.
Frequently asked questions
Does ContextClean upload my log?
The cleaner on this page runs in your browser and does not send the pasted log to a ContextClean server. Third-party browser extensions or services remain outside our control.
Can I trust automatic secret detection?
No automated detector catches every credential format. Treat the warning as an extra check and manually review the text before sharing it.
Why can removing log lines be risky?
A line that looks repetitive may still contain timing, environment, or call-order context. Compare the output with the original and restore anything needed to reproduce the failure.
Which AI tools can use the result?
The cleaned output is plain text, so it can be used with ChatGPT, Claude, Cursor, Codex, an issue tracker, or a teammate conversation.
Community discussion
When an AI answer still looks wrong, ask other developers.
Discuss prompt failures, misleading stack frames, context trimming, and safer ways to share a technical problem. Discussions are public and moderated through the ContextClean GitHub repository.
