past.dev
The most accurate long-term memory for AI agents.
past.dev is the most accurate long-term memory API for AI agents. #1 on BEAM, the largest public memory benchmark. Give your agents memory that stays accurate as facts change, across large teams and tens of thousands of emails, meetings, chats and documents. Add the past.dev API on top of your existing stack and give your agents a real past.
Hey Product Hunt 👋
I’m Mehdi, co-founder and CEO of past.dev. We are a small team in San Francisco building long-term memory for AI agents. We’ve worked on model context, memory and agents since GPT-2.
Before past.dev, we built agents for product work, engineering, email, meetings and action tracking. Every one of them needed memory that stays accurate as facts change, cites its sources, and only shows each person what they’re allowed to see. That memory is now past.dev, an API any agent can use.
What it does
- Send it conversations, emails, tickets and docs, with their original timestamp.
- Recall gives your agent what matters for a question, with dated sources. It keeps current and previous values, so it knows when a fact changed.
- Every memory keeps who can see it. It's built for multiplayer agents.
How we measure it
- #1 on BEAM, the largest public memory benchmark, at every size from 100K to 10M tokens.
- Highest score reported on DolphinBench, mem0’s new agent memory benchmark.
- In our tests, Claude Code with past.dev got 87% of DolphinBench tasks right, vs 54% with its built-in memory, at less than half the cost per task.
More benchmarks coming soon!
Try it in 2 minutes. Paste this into Claude Code, Codex, Cursor, Devin or any agent:
Set me up for past.dev. Read the full instructions at https://past.dev/agent-setup/pro... (with curl -fsSL when you can run commands) and follow them.
Your agent proposes a plan and tests on a little data before sending anything. New accounts start with 150,000 free credits, or 400,000 with a work email.
We directly with teams integrating past.dev, so ask us anything here. What should your agent remember?
