Ask in your own words

Say what you remember.
Land exactly there.

You rarely remember file names. You remember “the part about cricket”. Pick a kind of evidence and watch Memverix go straight to it.

Illustrative demo with sample data. Results anchor to real timestamps and pages in the app.

Drop anything

One library for every kind of file.

Drag in what you have. Text is extracted, scans are read, speech is transcribed and video is sampled, all on your Mac, all into one searchable index.

How it works

Your Mac does the work.
The assistant gets only what it asks for.

  1. 01

    Import

    Choose files or drag them in. Memverix keeps managed copies and fixes each page and timestamp anchor so citations never drift.

  2. 02

    Index on-device

    A local worker extracts text, runs OCR, transcribes speech and embeds the result. Your library and vectors never leave the machine.

  3. 03

    Ask & retrieve

    Search yourself, or let an authorized assistant call the connector. It fetches the specific passage, frame or clip, not your whole library.

Connect to ChatGPT

Give your assistant a memory it can cite.

Memverix speaks MCP, the open Model Context Protocol. Connect it to ChatGPT as a custom connector and your assistant can search your library and pull back the exact evidence, with the page or timestamp attached.

  1. Open Memverix on your Mac and sign in with Google to identify your account.
  2. Add the connector in ChatGPT developer mode with this address:
    https://memverix.evognix.com/mcp
  3. Approve the connection in the Memverix app. Every connection needs approval from your device, and you can revoke it any time.

Custom connector setup, not an app-directory listing. Memverix has not been approved by or listed in any ChatGPT directory.

Private by design

Local-first isn’t a feature.
It’s the architecture.

Files stay on your Mac

Your library, vectors and originals live in the app’s data folder. The public gateway stores no corpus and no vectors.

No model API key

Embeddings, OCR and transcription run locally. Memverix never calls a frontier-model API to index your files.

Evidence on request

An assistant gets the passages, frames and clips it asks for, with provenance, not a copy of your library.

You hold the switch

Approve each connection on your device and revoke it any time. Deleting a source never deletes your original file.

Read the Privacy Policy and Terms of Service, including how we handle Google sign-in data.

An honest note about signing

This build is ad-hoc signed and not yet notarized by Apple. macOS may say it can’t verify the app. Unzip and drag Memverix to Applications. If macOS blocks it, open System Settings → Privacy & Security, scroll to Security and choose Open Anyway (on older macOS, right-click → Open works). We’ll move to notarization and say so here when it lands.

FAQ

Good questions.

Do my files leave my Mac?

No. Import, extraction, OCR, transcription and embeddings run on your Mac. When you connect an assistant, only the evidence it requests (a passage, a frame, a clip) is returned to it through the authenticated connector.

Why does macOS warn me when I open it?

The current build is ad-hoc signed but not notarized by Apple. Open System Settings → Privacy & Security, choose Open Anyway next to Memverix, then confirm. Or run xattr -dr com.apple.quarantine /Applications/Memverix.app in Terminal. This is a one-time step per download.

Do I need an OpenAI or other API key?

No. Indexing and search never call a frontier-model API. Your assistant, such as ChatGPT, uses its own account when it reasons over the evidence.

Does it analyse every frame of a video?

No. Video is indexed through sampled frames plus transcribed speech. Memverix shows extraction warnings per source so you know what was and wasn’t covered.

What else do I need to install?

FFmpeg, Poppler and Tesseract are used for media extraction, PDF page rendering and OCR, and are not bundled yet. You can install them with Homebrew. The first launch also downloads the local runtime and model weights.

Is it approved in the ChatGPT app directory?

No. You add Memverix as a custom connector in developer mode. We make no claim of directory approval.

How do I remove a file or revoke access?

Delete the source in the app. This removes its managed index data but never your original file. Revoke any assistant connection from the app at any time.

Stop scrubbing. Start landing.

Put your files in once. Ask in plain words. Jump to the exact moment.
