What is Bilinc?
Bilinc is an AI developer tool that gives AI agents a verifiable, versioned memory store so they can remember information across sessions and prove where each fact came from. It is a hosted memory service rather than a plain vector database: every write records its source, a timestamp, and the value it replaced, and recall returns that provenance alongside the stored memory. Teams building with coding agents such as Claude Code, Cursor, and Codex connect to it over the Model Context Protocol, or through a Python SDK and CLI, and share a common agent workspace. Concrete features include diff comparison that shows every addition, change, and removal between two points in time; snapshots with rollback so an agent state can be checkpointed and restored; and a full audit trail of which app or agent wrote each value and what it overwrote. Because earlier values stay in a memory's history rather than being overwritten silently, Bilinc suits anyone who needs to debug agent behaviour or explain why an agent held a particular belief. For builders comparing AI memory layers in the BestAIFor directory, its emphasis is auditability and version history rather than raw retrieval speed. The free tier covers 2,000 operations per month with no credit card, which is enough to wire a single agent into the memory layer and test recall-with-provenance before committing to a paid plan.
What is Bilinc used for?
Giving AI agents persistent, versioned memory with source provenance, diffs, snapshots, and rollback for auditing agent behaviour.
How much does Bilinc cost?
Pros and cons
Pros
- Versioned writes record source, timestamp, and the previous value so every memory has an audit trail
- Diff comparison shows all additions, changes, and removals between two points in time
- Snapshots and rollback let you checkpoint and restore an agent's memory state
- Connects over Model Context Protocol plus a Python SDK and CLI, covering Claude Code, Cursor, VS Code, and ChatGPT
- Free tier of 2,000 operations per month with no credit card required
Cons
- Paid tier pricing beyond the free 2,000-operation allowance is not published on the homepage
- Focused on auditable memory, not a general-purpose vector database for large-scale semantic search
- Value depends on running agents through MCP-compatible clients, so non-MCP setups need the SDK or CLI
- Young hosted service, so long-term reliability and scaling limits are not yet proven publicly
Questions about Bilinc
What is Bilinc used for?
Bilinc is a hosted memory service for AI agents. It lets agents remember information across sessions while recording each memory's source, timestamp, and prior value, so you can trace where a fact came from and how it changed.
How is Bilinc different from a vector database?
A vector database stores embeddings for similarity search; Bilinc stores memories with full version history, provenance, diffs, snapshots, and rollback. It is built for auditability and explaining agent behaviour rather than raw semantic retrieval.
Is Bilinc free?
Bilinc has a free tier covering 2,000 operations per month with no credit card required. Additional paid tiers exist, but their prices are not published on the site.
Which tools does Bilinc integrate with?
Bilinc connects over the Model Context Protocol to clients such as Claude, ChatGPT, Cursor, and VS Code, and also offers a Python SDK and CLI for direct access from your own code.
What are the best alternatives to Bilinc?
Mem0, Zep, and Letta (MemGPT).
