pebble‑1.2 · now with voice mode + agent actions

Your AI, but it actually knows you.

Pebble remembers what you talked about last Tuesday, who you mentioned at brunch, and the way you actually take your coffee. Long‑term memory, end‑to‑end encrypted, and yours to delete.

Marcato Trattoria in Brooklyn — you mentioned it on Nov 14 when we were planning the Q4 offsite. The pull‑quote you liked: "fresh pasta is the only meal everyone will eat." Want me to check availability for Dec 18, around 7pm? I have your team size as 14.

§ EVERYDAY USES

Five things that become effortless when Pebble remembers.

Plans

Plans that book themselves

Mention dinner with friends once. Pebble pulls dates, locations, dietary notes, and books it — with everyone CC'd.

"book Marcato, Dec 18, 7pm — flag vegetarian for Ana"
Recall

"What was that thing…"

The book your therapist recommended. The model number on your router. The wine you liked. Stop searching your own Notes app.

Quiet long‑term tracking

"My back hurt for three days last month after the trip." Pebble noticed, kept the thread, and connects the dots when you ask.

§ ARCHITECTURE

Two stores, one retrieval pass.

Pebble splits memory between episodes (the literal moments — what you said, where, when) and a concept graph (the people, places, projects, and preferences it inferred). Every reply pulls from both, and tells you which.

  • concept Ana → vegetarian, no mushrooms

§ MODEL & MEMORY CARD

pebble‑1.2 · personal

A reasoning model paired with a private long‑term memory store. Memory is encrypted with a key only your device holds.

§ DEVELOPER ACCESS

Build on the memory layer.

Pebble exposes a scoped Memory API — your apps can read and write to a user's memory only with their explicit consent.

@pebble/sdk · 1.2.1
from pebble import Pebble

p = Pebble(user_token="ut_…")

answer = p.ask(
    "What was that Italian place for the offsite?",
    scope=["projects", "contacts"],
    cite=True,
)

# every claim ships with the source memory
for c in answer.citations:
    print(c.kind, c.date, c.snippet)
§ PRICING

Cheaper than the apps it replaces.

Plus and Pro are billed monthly, no annual lock‑in. You can switch tiers up or down anytime and your memory follows.

§ FAQ

Memory, but the responsible kind.

Where is my memory stored, and who can access it?+
Encrypted at rest in your region (US, EU, or Australia) with a key held on your device — not on our servers. No Pebble employee can read your memory; an internal audit log records every access. Memory used to generate a reply is sent to the model in an ephemeral context that's discarded after the response.
How is this different from ChatGPT with memory?+
Three differences. (1) Pebble's memory is structured (episodes + a concept graph), so it can answer "what did we decide on Nov 14" — not just surface a vague vibe. (2) Every reply cites the memory it pulled from. (3) Memory is portable and encrypted; you can export the whole graph as JSON whenever you want. On LongMemBench‑v2 we score 94.1% vs ChatGPT's 38.4%.
Can I export or delete my entire memory?+
Yes — one click in Settings → Memory. Export gives you a JSON file (episodes + concept graph) plus a human‑readable Markdown summary. Delete is permanent within 7 days; after that, encrypted backups roll off automatically. You can also delete individual memories with a swipe in any chat.
What integrations does it have — calendar, email, contacts?+
On Pro: Google + Apple Calendar, Gmail, iCloud Contacts, Things, Notion, Apple Maps, and Reservation Hub (OpenTable + Resy). Pebble requests each scope individually and shows you a memory diff before any agent action that writes to an external service.
Does it work offline?+
Partially. On iOS and Mac, recent memory and the smallest Pebble model run on‑device for short questions and recall — handy on a plane. Voice mode and agent actions require the cloud model. Anything you do offline syncs and refines the next time you connect.
