Abigail. private memory for every AI
Abigail, a warm librarian in glasses and a cream cardigan at her reference desk — green banker's lamp, a nameplate reading ABIGAIL, books in hand, tall library shelves and a second-floor gallery behind her open any AI — she picks up where you left off
Download for Windows

Mac · Apple silicon / Mac · Intel

Free. No account, nothing to sign up for. Windows 10/11 or macOS 11+.
Windows is signed as Mediagato LLC; Mac isn't stamped by Apple yet — one extra click the first time, explained below.

In a browser tab — ChatGPT, Claude, Gemini? Grab her browser companion too — one click, without it she can't see the tab.

Every AI you open treats you like a stranger — so you explain yourself again and again. Abigail remembers, and hands it back wherever you go next: ChatGPT, Claude, anywhere. Leave her alone a while and she'll group what belongs together onto shelves of her own — then tell you what she noticed.

Tell ChatGPT on Tuesday that you teach year four and Marcus needs everything read aloud. Open Claude on Friday, ask it to plan a lesson — Abigail has already passed along the note. You never said it twice.

Works across thirteen AI sites — Claude · ChatGPT · Gemini · Mistral · Meta AI · Perplexity · Copilot · Grok · DeepSeek · Google AI Studio · Poe · T3 Chat · Qwen, plus any AI you host yourself. Checked against the real pages before every release — twelve confirmed, DeepSeek still in progress.

She works for you and no one else — no head office, no account, nobody she reports to. Your shelves stay in your house, because that's the only place they exist. Exactly what she reads, and what she never sends →

On a Mac, her first opening takes one extra click

The Windows installer is signed as Mediagato LLC, so it opens straight away. On a Mac she isn't yet — Apple's stamp is a separate piece of paperwork we haven't finished — so macOS will stop her the very first time and say it can't check who made her. It's the standard warning for a small workshop, not a verdict on her.

  1. Drag Abigail into your Applications folder as usual.
  2. Right-click her there — Control-click works too — and choose Open.
  3. Click Open once more in the dialog. That's it; from then on she opens with a double-click like anything else.

On macOS 15 Sequoia, or if right-click didn't take: double-click her, click Done on the warning, then go to System Settings → Privacy & Security, scroll down to the line saying Abigail was blocked, and choose Open Anyway.

Found her at $11.11 — make a wish.

Abigail's free, and her core always will be. This is something else — a founding shelf, twenty places, $11.11 once.

There's a lot planned for Abigail Pro. When it arrives, founding members get every future feature free, forever — our thank-you for believing in her early. Nothing here is locked today; this just hands you the founding key now.
