Pick a tool
New tools get added to this bench over time.
Privacy Scrubber
Replaces sensitive details with placeholders like [EMAIL_1]. Check the result yourself before sending: automatic detection can miss things.
Put the real values back
Paste the AI's reply here. Placeholders from your last scrub are swapped back. The map lives only in this open page, so keep it open until you're done.
Token & Context Meter
Estimates only. Real tokenizers differ by model and language, so leave a safety margin of 10 to 20 percent.
Context windows listed are common round sizes, not specific models. Check your tool's actual limit, and remember the AI's reply also uses part of the window.
AI Output Cleaner
Paste a chat answer and choose what to strip. Good for emails, documents and posts where markdown symbols would show up as clutter.
Prompt Vault
Your prompts are saved in this browser on this device, and nowhere else. Export a backup file now and then, and import it on another device to bring them along.
Output Scorecard
Comparing two AI answers by feel is easy to get wrong. Score each one on the same criteria, weight what matters most, and let the totals settle it. Rename, add or remove criteria to fit your task.
Context Pack Builder
An AI answers better when it gets the background in an organized form. Fill in the blocks you need, switch off or reorder the rest, and copy one tidy pack to paste at the start of a chat.
Your pack
Text Compare
Ask an AI to polish your draft and it may change more than you asked for. Paste both versions to see every change. Struck-through red text was removed, and underlined green text was added.
Structured Output Checker
When an AI is asked for JSON, it often adds a code fence, a trailing comma or single quotes that break the next step. Paste its output to find the exact problem, repair the common ones, and check the fields you expect.
