The offline engine for
your reading and research
Turn any digital source into a structured, queryable knowledge base. Stored locally on your device with zero cloud lock-in.
A knowledge base that compounds.
A local, AI-powered research vault that structures, links, and compounds your knowledge over time.

Comparison is a directional summary, not a benchmark. Some of these tools are great. Trisynapse is built for the research loop that compounds over time.
Digital hippocampus on your desktop.
Trisynapse models its architecture after the brain's memory circuit, separating similar concepts, compiling summaries, and linking new data dynamically.
The first stop for every sight, sound, and idea your brain takes in. Filters the world before it reaches memory.
Paste a link, drop a file, hand it a paper. Trisynapse extracts clean Markdown the same way your cortex pre-processes the world.

Paste a link, drop a file, hand it a paper. Trisynapse extracts clean Markdown the same way your cortex pre-processes the world.
The name "Trisynapse" comes from this circuit: three synapses (EC → DG → CA3) that gate every memory you have ever made.
All your tools, in one place.
Bring your library, notes, and AI assistant under a single folder.
Creating memory
Build a topic-based knowledge vault from any source.
Create a topic
Organize research by area. Inbox, wiki, monitoring, and chat all live inside a topic - the boundary for everything else.
Ingest from anywhere
AI summarization
Wiki compilation
Talking to memory
Ask questions grounded in your own sources.
Wiki chat
Chat with a single wiki article and its sources. Ask the AI to edit, refine, or extend the article in place.
Multi-topic reasoning
Visualizing memory
See your knowledge as a graph and a 3D map.
Knowledge graph
A force-directed graph of topics, concepts, and sources. Click any node to jump in. Discover connections you forgot you made.
3D semantic map
Automate & monitor
Let Trisynapse grow your vault while you sleep.
Topic monitoring
Scan arXiv, X, and the web for new material related to active topics. Items land in a review queue - you decide what enters the vault.
Model orchestration
Feedback rules
Detailed dashboard
Activity, feedback & versions
Make the AI loop transparent and correctable.
Background jobs
Summarization, compilation, embedding rebuilds, and monitoring scans run as tracked jobs. Errors, retries, and outputs are inspectable.
Version history
Audit & usage
A continuous cycle of synthesis.
From fresh inputs to organized wikis, your library automatically compiles and structures itself.
Ingestion
Import from any link, file, or integration. Text is extracted as clean Markdown instantly.
Navigate your mind in 2D and 3D.
Explore relationships visually with a concept graph or find clusters in a 3D semantic map.
Engineered for precision
High-performance orchestration and local-first databases.
