Your data never leaves your infrastructure

Life With & Without MemVid

Without MemVid your vector DB balloons and slows. With MemVid every agent gets fast, low-cost memory it can search, recall, and carry forward—no re-indexing, just share a 50 KB capsule.

Without MemVid

Cold-start cost

Re-embed every record

Disk / RAM ratio

3-5× data size

Live branching

Not supported

Portability

Complex infrastructure

Multi-modal

Mostly text only

With MemVid

Cold-start cost

Zero — pre-encoded

Disk / RAM ratio

0.4× thanks to video codec

Live branching

Create branches in milliseconds

Portability

One .mv2 file

Multi-modal

Text • Images • Model Weights

Built for real-world AI workflows

Everything you need to manage AI memory at scale

Video-Based Storage

Store millions of text chunks as frames in MP4 files. 10x more efficient than traditional databases.

Single portable MP4 file

Semantic Search

Find relevant information instantly using natural language queries. No SQL, no complex queries.

Sub-second retrieval

Self-Adapting & Time Travel

Rewind any branch to past states or fast-forward with new knowledge. Models keep learning—your memory evolves without re-encoding.

Branch, replay & evolve

Interactive Chat Interface

Built-in Q&A interface to chat with your stored knowledge. Supports multiple LLM providers.

Create Video Memory

from memvid import MemvidEncoder

# Create encoder and add text chunks
encoder = MemvidEncoder()
encoder.add_chunks([
  "The Earth orbits the Sun.",
  "Water boils at 100°C.",
  "Python is a programming language."
])

# Build video memory
encoder.build_video("knowledge.mp4", "index.json")

Chat with Your Memory

from memvid import MemvidChat

# Initialize chat with video memory
chat = MemvidChat("knowledge.mp4", "index.json")
chat.start_session()

# Ask questions
response = chat.chat("What temperature does water boil?")
print(response)

# Output: Water boils at 100 degrees Celsius.

PDF Document Support

from memvid import MemvidEncoder, MemvidChat

# Index PDF documents
encoder = MemvidEncoder()
encoder.add_pdf("research_paper.pdf")
encoder.add_pdf("documentation.pdf")
encoder.build_video("docs.mp4", "docs_index.json")

# Search across all PDFs
chat = MemvidChat("docs.mp4", "docs_index.json")
answer = chat.chat("What are the key findings?")

# Instant semantic search across all documents
