What we checked ourselves
Not copied from the project's own blurb. These are things we opened and verified, with the date.
- 7 Sept 2026We checked that the link to the project still resolves.
- 13 Sept 2026We read the licence text itself (LICENSE). No unusual restrictions were stated.
- 31 Aug 2026We read the project's own documentation and found no sign that development has stopped.
Where this sits among the 114 tools we list in AI agents
- No API key required29 of 114
- Keeps your data on your own machine11 of 114
- Commercial use confirmed as allowed95 of 114
- Requires terminal commands21 that do not →
Only 9 of the 114 meet all of the conditions above.
Counted from our own checks: every tool we list is examined against the same criteria.
What it does
Bundles data, embeddings and search structure into a single versioned file, so long-term memory travels with the agent instead of requiring a database to stand up alongside it. Retrieval is fast and the file can simply be handed to another environment. The published accuracy and latency gains are the project's own benchmarks, worth reproducing on your workload. Note the flip side of portability: one file leaking means the entire memory leaks. Apache-2.0.

memvid FAQ
- Is memvid free?
- Yes. It runs on your own machine, so there is no usage-based cost either.
- Do I need to install anything or write code to use memvid?
- It needs the command line. If you are not comfortable typing commands, expect to get stuck during setup.
- Does memvid work on a phone?
- No. It needs a computer.
- Can I use memvid commercially?
- The licence is Apache-2.0, which permits commercial use. Conditions such as keeping the copyright notice still apply, so read the licence text before shipping it inside something.
