# Build a full knowledge graph locally with any video > Source: > Published: 2026-06-20 00:50:02+00:00 **Offline Video Search, Scene Segmentation, Speech Transcription (Whisper), Speaker Diarization, and SQLite + Qdrant Semantic Search on Windows 11** [ ](https://askgoodq.com/) (Note: The optional Ask GoodQ voice agent is a hosted extension using ElevenLabs APIs. The core GoodQ4All memory system itself is 100% local and offline.) GoodQ4All is a **100% private, offline alternative** to cloud-based media intelligence services. It ingests video, audio, and text files into queryable, structured scene-level memories, persisting the knowledge graph and vector representations locally on your computer. Following a strict **"proof-backed" system doctrine**, GoodQ4All documents every perception step, tracks evidence manifests, and logs a comprehensive audit trail so that every memory claim can be verified. - **Get This Level of Local Control (Unified Operator UI):** *Click the preview above to watch the high-fidelity onboarding video.* - **From Video Quality as Low as This: (Raw Media Inputs):** *Apollo 11 Moon Walk (nasa_descent.gif)* *Saturn V Launch (nasa_launch.gif)* - **Using This All-in-One Installer (Unified Windows Installer):**[🚀 Download GoodQ4All Setup v2.4.0.exe](https://github.com/GoodQ02/goodq4all/releases/download/v2.4.0/GoodQ4All_Setup_2.4.0.exe)[!IMPORTANT] **System Requirement: Windows 11 only.** GoodQ4All is built for Windows-first local execution. It requires at least**25 GB** of free space to store local database structures, models, and cache files.**SmartScreen Workaround:** Since the setup installer is currently self-signed, Windows SmartScreen may show an "Unknown Publisher" dialog. Click**More info** and select**Run anyway** to proceed.**Integrity Checksum:** Verify your download authenticity by running the following command in PowerShell:Expected SHA256 hash: Refer to the GitHub Releases page for the latest signed executable checksum. ``` Get-FileHash GoodQ4All_Setup_2.4.0.exe ``` Machine memory should earn every claim it makes. GoodQ4All generates step-by-step logs (`step_runs.jsonl` ), scene manifests, and intermediate features for every ingested file. **Single-Use Confirmation Tokens**: Ingestion submission routes are protected by a server-generated token handshake with single-use nonce validation, preventing unauthenticated/out-of-bounds execution.**Epistemic Verification**: Ingestion is tracked using verifiable manifests and SQLite-backed relational schemas.** No Silent Failures**: The Control Agent and Watchdog processes bubble errors directly to the operator consoles, providing absolute visibility into the execution stack. To run large-parameter local models safely on consumer hardware (e.g. RTX 4070 Ti SUPER 16GB) without Out-of-Memory (OOM) crashes, GoodQ4All implements strict VRAM and execution controls: **Model Lifecycle Manager**: A specialized context manager (`lib/model_lifecycle.py` ) that audits free VRAM using PyTorch and`nvidia-smi` before loading models, dynamically evicting idle networks from GPU memory.**Local Agent Stack (**: Gated LLM reasoning and local tool execution through zero-dependency policy enforcement middleware, loading schemas, policies, and contracts dynamically from the version-controlled`MiniAgentClient` )`agents/stack/` directory.**Endpoint Fallback Orchestration**: Automatically falls back from the primary local vLLM server (`prefer_speed` , running Qwen2.5) to a local Ollama service (`prefer_quality` , running Phi-4) or a CPU-safe model variant when VRAM thresholds are breached. High-precision 32-bit floating point embeddings are persisted in Qdrant and FAISS. For rapid candidate filtering, GoodQ4All uses **TurboQuant**—an SQLite sidecar caching technology employing Lloyd-Max Polar Quantization and Johnson-Lindenstrauss residual projections. **Performance:** Achieves sub-millisecond candidate pre-filtering.**Accuracy:** 100% search accuracy is maintained by performing the final rank scoring on the uncompressed raw float32 vectors. Note **Hybrid Precision Caching Model**: GoodQ4All uses an additive **sidecar vector cache** architecture. High-precision 32-bit floating point (`float32` ) embeddings remain the authoritative truth of the system, stored in Qdrant and FAISS. Performance-oriented query pre-filtering is handled via lightweight **TurboQuant** fields (Lloyd-Max Polar Quantization + Johnson–Lindenstrauss residual corrections) stored in SQLite. This ensures zero data loss, guarantees rollback capability, and cuts memory usage. The pipeline dynamically adjusts its computational needs to match your system specs: `BASELINE` (CPU-safe): Fully operational, offline-ready execution on standard CPU hardware. Bypasses GPU requirements gracefully.`GPU_ENHANCED` : Activates local NVIDIA GPU (CUDA 12.1) and WSL2 accelerated audio processing paths for fast, high-volume ingestion. GoodQ4All compiles the isolated Python environment, the Qdrant database, and perception libraries into a single executable wrapper: - Download and run `GoodQ4All_Setup_1.0.0.exe` . - Launch **GoodQ4All** from the desktop shortcut. - Open the local **Retro Memory Explorer** dashboard at`http://127.0.0.1:30000/ui/retro_console_v1/` . - Drag-and-drop video/audio files onto the yellow-dotted **Upload Pad** to begin automatic ingestion. If you are developing, customizing the pipeline, or running from source: **Developer Source Setup Steps (Advanced)** GoodQ4All ships with two local operator console variants: **Classic Operator Console**(served at`/ui/operator_console_v1/` ): Exposes the current scope strip, flight deck, proof/evidence status, recurrence reports, and video inventories.**Retro Memory Explorer (v1.4.7)**(served at`/ui/retro_console_v1/` ): A premium cyber-CRT dashboard featuring a four-panel resizable/collapsible layout with floating restore tabs, an entity co-occurrence graph with dynamic zoom and flight transitions, an Inspector panel containing keyframe image/transcript views, and bidirectional timeline checklists. - Guided demo: `docs/guides/DEMO.md` - First run: `docs/guides/FIRST_RUN.md` - Install: `docs/guides/install/INSTALL.md` - Quickstart: `docs/guides/install/QUICKSTART.md` - Clean memory start: `docs/guides/CLEAN_MEMORY_START.md` - Data Privacy: `docs/guides/general/PRIVACY.md` - Architecture: `docs/architecture/SYSTEM_ARCHITECTURE.md` - Memory Storage: `docs/architecture/MEMORY_STORAGE.md` - Hybrid Caching: `docs/architecture/TURBOQUANT_HYBRID_CACHING.md` - Current Agent State: `docs/agent/CURRENT_STATE.md` MIT.
