A Simple
Second Brain for
Enterprise & Students
Organize and search your knowledge in one place with AI copilot, plus specialized AI solutions for oil & gas, from well logs to production forecasting.

One dock for your whole subsurface workflow

We help data centers
drink less water.
Every AI query you run spins up GPUs in a data center, and cooling those chips evaporates fresh water. A conventional second brain gulps that water with every search. Simple Second Brain sips it.
By leaning on efficient, knowledge-based retrieval instead of constant heavy inference, it does more with far less compute, so your knowledge workflow stays light on the planet.
Conventional Second Brain
Thirsty by design
- Every query hits a large cloud LLM
- Heavy GPU inference for each search
- Big vector databases running around the clock
- High energy draw and cooling-water footprint
- Your notes leave your device to be embedded
Simple Second Brain
Sips, not gulps
- Knowledge-based retrieval with lightweight models
- Minimal compute per query, answers in a blink
- Lightweight on-demand indexing, with no vector database running around the clock
- A fraction of the energy and cooling water
- Your documents stay in your workspace and are never embedded into third-party models

16S rRNA Sequencing Meets H₂S Souring Risk
Reservoir souring is one of the costliest problems in oil and gas. Sulphate-reducing bacteria generate hydrogen sulphide (H₂S) that corrodes pipelines and facilities, triggers safety shutdowns, and discounts sour crude at the wellhead. The bill runs into billions each year across corrosion, chemical treatment, lost production and HSE exposure, and H₂S is lethal to workers at just a few hundred parts per million.
Catching souring early is far cheaper than reacting to it. Upload FASTQ files from DADA2 pipelines or processed taxonomy CSVs and get instant SRB detection, souring risk scores, diversity metrics, and biocide treatment recommendations, so you can intervene before H₂S ever shows up in the sales line.
- ✓Predict souring risk early, before corrosion and shutdown costs hit
- ✓Knowledge-based scoring engine, no training data required
- ✓374-ASV reference database from real oilfield samples
- ✓Percentile ranking, community composition, feature importance
