What is Preserver?
If you're searching for the meaning of "preserver" as a life-saving flotation device, or as something used in food preservation, this isn't that.
Preserver is a mobile app for iOS and Android that turns your phone into a real-world data collector. It captures photos, video, voice recordings and text notes, and automatically stamps every one with the exact time, date and GPS location — creating a verifiable record of when and where something happened.
Then it does what no camera roll can: it exports everything as a structured, AI-ready bundle — media, transcripts, locations, timestamps and integrity hashes in machine-readable format. Drop the bundle into ChatGPT, Claude, Gemini, Grok or NotebookLM and turn a day in the field into a finished report in minutes. Capture is free, works offline, and needs no registration.
Everything you need to preserve your activities
Works Offline
No Wi-Fi. No Bluetooth. No mobile data. Capture with full metadata anywhere — underground, in the air, or miles from the nearest tower.
Verified Ground Truth
Every capture carries irrefutable time, date and GPS metadata, protected by SHA-256 integrity hashes. AI outputs are only as good as their inputs — Preserver makes your inputs provable.
AI-Ready Exports
One tap exports your whole activity as a structured bundle: JSON manifest, voice transcripts, media, locations and timestamps. Built to be read by ChatGPT, Claude, Gemini, Grok — or your own tools.
Private by Design
No registration. No account. Your data stays on your device — and we never use your captures to train AI. You decide which AI sees your data, if any.
How It Works
Open Preserver
No login. Just tap the icon and you're ready.
Capture Anything
Type a note, record your voice, snap a photo, or shoot video.

Time, date and GPS are baked into every capture — automatically.
Export AI-Ready
One tap creates a structured bundle: manifest, transcripts, media, metadata.
Generate Content
Feed the bundle to your AI of choice and get reports, summaries and timelines — grounded in what actually happened.
Your Day in the Field, Written Up by AI — Grounded in Fact
AI can write anything. The problem is proving it's true. Preserver solves the input side: every observation you capture is timestamped, geolocated and hash-verified, then packaged in a format AI understands.
- Walk the site, visit the client, inspect the asset — capture as you go
- Export the activity bundle when you're done
- Upload it to ChatGPT, Claude, Gemini, Grok or NotebookLM
- Ask for what you need: an inspection report, incident summary, compliance record, case timeline or meeting minutes
Try this prompt with your export:
"Read this Preserver export bundle. Using only the captured observations, transcripts, timestamps and locations, write a professional site inspection report with a chronological timeline and a photo reference index."
Hallucination-proof your paperwork. If it's in the report, it was captured in the field.
Who It's For
Tradies & Contractors
Capture the job as you do it. AI writes the completion report, variation claim or defect log from your verified photos and voice notes.
Field Professionals
Process servers, inspectors, assessors, surveyors: evidence-grade capture in, court-ready or client-ready documents out.
Journalists & Researchers
Verifiable source material with time and location. Feed observations to AI for transcription-grounded drafts.
Compliance & Care
NDIS providers, auditors, safety officers: structured, timestamped records that satisfy the regulator and write themselves up.
AI Builders & Data Teams
Real-world, geolocated, timestamped ground truth — structured, machine-readable and integrity-verified at capture.
Everyone Else
Travel journals, family archives, life logging — captured offline, preserved with proof of time and place.
AI-Ready. Never AI-Harvested.
Preserver is built on one principle: your data works for you, not for us. Nothing leaves your device unless you export it. We never sell your data, never mine it, and never use your captures to train AI models — ours or anyone else's. When you export an AI-ready bundle, you choose which AI reads it, under your account and your terms.
