Signal Filter
Cut the fluff out of long text.
Paste in a meeting transcript, article, or report. You get back only the sentences that actually say something — and everything else disappears.
Everything runs on your device — nothing is uploaded, ever
Your work stays
yours.
Cut through noisy text, find out which of your notes still matter, and keep a tamper-proof record of what AI actually told you — without anything leaving your computer.
No sign-up. No account, no email, no catch.
Nothing uploaded. Your words never touch a server.
Keeps receipts. Proof you can show, not just trust.
Three tools. One promise.
Your words never leave your device — and every result comes with proof you can keep.
Memory Thermometer
Know which notes still matter.
Notes go stale like food. This reads through your saved thoughts and tells you which ones are worth keeping — and which ones expired months ago.
Answer Receipts
Proof of what AI actually said.
Ever needed to prove an assistant gave you a specific answer on a specific day? This locks every response with its question and time into a sealed, tamper-proof record — like a receipt for your conversation.
These browser demos use the exact same logic as our offline tools. The difference: nothing here ever leaves this tab.
Three steps. Zero accounts.
No downloads, no sign-ups, no waiting on approval.
1
Paste your text.
A transcript, a page of notes, an AI answer — anything goes straight in.
2
Get a clear result.
The important lines surface to the top. Stale notes get flagged. Answers come sealed with proof.
3
Keep it or share it.
Download your results, export them anywhere — they're yours alone, and always provably unaltered.
Why "private by default" matters
Most tools ask you to trade your words for convenience. We think that's a bad deal — especially when the work is sensitive, unfinished, or simply yours.
Nothing in the cloud
Your words are processed locally and never transmitted anywhere.
No hidden watching
No trackers, no analytics, and nothing sold or shared — by design.
Works offline too
Plane, subway, dead zone — if you can open a file, you're covered.
"If a tool can't prove what it did with your data, don't trust it with any."
Get early access
We'll email you when new tools ship and improvements land. No spam — just the occasional update from people who care about private software.
