Each tool remembers only itself

Claude, Cursor and Copilot each keep some memory now, but it stays inside that one tool and that one account.

1 memory

Yes, adding retries now.

ContextForge keeps one memory for every tool and teammate. See how it works

One memory. Every tool.

Connect the tools you already use. They all read and write the same project memory.

What your agents can do with it

Plain tools your agent calls on its own.

memory_query01

Finds it by meaning.

Ask in plain language, without exact keywords or tags.

query

how do we handle payment failures?

1 match · DecisionNo automatic retries on the payment webhook.↳ src/payments/webhook.ts

memory_check_freshness02

Knows when a memory went stale.

If the code a memory points to changes, the memory gets flagged before an agent trusts it.

src/payments/webhook.ts changed

Decisionmay be outdated

No automatic retries on the payment webhook.↳ src/payments/webhook.tsmemory_git_commits03

Remembers what shipped.

Commits from your connected repos sit next to your notes, so an agent answering today knows what shipped yesterday.

main

a41c9e2 Add idempotency key to payment webhookyesterday · PR #214

3f9b21c Stop automatic retries on payment webhook3 weeks ago · PR #187

session_list04

See what else is running.

Check which other Claude Code sessions are live before a big change.

tasks_list05

Keeps the to-do list.

Tasks stay with the project, not in one chat.

memory_ingest06

Saves the why.

Decisions keep their reason, so the next agent does not undo them.

Also included

Spaces

Separate memory per repo, service or team.

Snapshots

Point-in-time copies you can restore or diff.

Team

Shared spaces with per-member roles.

Import / Export

Move memory in and out as JSON or Markdown.

API keys

Scoped keys for CI and your own scripts.
