About past.dev

past.dev is a long-term memory API for AI agents. It helps large teams keep agent memory accurate over time across emails, meetings, chats, and documents by layering memory on top of your existing stack.

Key Features

In practice, you ingest data with original timestamps and audience context, then query for memories and retrieve ranked evidence with sources:

Ingestion with Timestamps and Audience Context

POST /api/v1/ ing est stores text with a timestamp, label, and audience so backfilled data keeps its original date.

Recall with Evidence and Dated Sources

POST /api/v1/recall returns a ranked list with an asOf timestamp, plus sources and excerpts that support each result.

Privacy by Design and Compliance

Each user sees only what they’re allowed to; SOC 2 Type II, ISO 27001, ISO 27701; deployable as managed service or in your cloud.

Quick Setup and Flexible Deployment

Set up in about 2 minutes with an API key; works atop your existing stack with either managed hosting or direct cloud deployment.

Summary

Best for product teams building AI assistants, sales teams tracking customer conversations, and customer-support teams needing durable context.
