Your Personal Coding Taste.
Learned Once. Applied Everywhere.
Cell is a revolutionary local daemon that captures your coding style, naming structures, and logic preferences as you edit code across Cursor, VS Code, Windsurf, or your CLI. It then quietly feeds your unique style signature back into every AI tool you use, resolving model amnesia forever.
Walled-Garden Amnesia
Proprietary AI code assistants trap your preferences inside their walled gardens. What you teach Cursor is completely lost on Claude Code.
What you correct in Windsurf is repeated by Copilot.
Unified Local Daemon
Fivo Cell operates a lightweight, private background daemon that silently maps your style signatures locally, feeding them automatically back into every public model.
Fivo Cell vs Walled Gardens
A detailed breakdown of capabilities comparing Fivo Cell against proprietary autocomplete extensions and walled-garden IDEs.
| Capability | Fivo Cell | GitHub Copilot | Cursor | Continue |
|---|---|---|---|---|
| Learns coding style | Dynamic (Local diff analysis) | No (Static global weights) | No (Static context only) | No (System prompt template) |
| Cross-tool portability | Yes (5+ tools: VS Code, Cursor, Windsurf, etc.) | No (Locked to VS Code/JetBrains) | No (Locked to Cursor fork) | Yes (VS Code/JetBrains plugin) |
| Build failure prediction | Yes (Local compilation checks) | No | No | No |
| 100% local privacy | Supported (Zero telemetry, offline first) | No (Forces cloud transmission) | No (Telemetry defaults on) | Supported (Custom endpoint configuration) |
| Open source core | Apache 2.0 | Commercial | Closed source | Apache 2.0 |
Features Built For Elite Engineers
Cell runs silently in the background, making every AI code completion understand your exact logic preference.
Cognitive Taste Learning
Silently watches and extracts naming patterns, folder layout preferences, and library signatures, recording your style fingerprint locally with absolute precision.
Seamless IDE Continuity
Bridges preferences instantly across 5+ surfaces. What you write in VS Code is instantly pushed to Cursor, Windsurf, and Claude MCP.
One profile, everywhere.
Pre-Execution Diagnostics
Catches syntax crashes, missing awaits, circular imports, and API key exposures inside your editor before you even trigger the build script.
Code Health Blueprints
Scans for dead functions, redundant structural classes, and update readiness, serving clean refactor suggestions directly to your local screen.
100% Zero-Telemetry Isolation
Your raw source code, credentials, and Git history never leave your machine. Cell runs completely isolated with zero telemetry by default.
Developer-Owned Apache-2.0
Fivo Cell is completely open-source, free, and community-driven. Fork the daemon, build custom extensions, and own your cognitive layer forever.
Cognitive Compilation Pipeline
Analyze how Fivo Cell converts active IDE context into mathematical style vectors locally.
Abstract Syntax Parsing
Local parser scans active editor buffers and extracts AST nodes during active code updates.
Preference Mining
Extracts identifier casings, tab spaces, library choices, and method structure signatures.
Taste Vector Compilation
Generates compact, anonymized style indices written directly to a local configuration file.
Multi-IDE Injection
Local MCP server feeds style vectors directly back into Cursor, Claude Code, or global shells.
JSON Configuration Schemas
Explore the local files automatically generated by Fivo Cell to configure your workspace APIs.

Frequently Asked Questions
Everything you need to know about Fivo Cell.
What is Fivo Cell?
Fivo Cell is a lightweight local daemon (npm installable: npm i -g fivocell) that watches your code editor, extracts your unique coding style and structural preferences, and feeds that style back into every AI assistant you use.
How does Fivo Cell learn my coding style?
Fivo Cell runs a local Abstract Syntax Tree parser on your active editor buffers, then extracts preference signals: identifier casings, tab vs space, library choices, method signatures, error handling patterns, comment style, and dozens more. These are compiled into a compact taste vector.
Which IDEs does Fivo Cell support?
Fivo Cell works with Cursor, VS Code, Windsurf, Claude Code, JetBrains IDEs (IntelliJ, PyCharm, GoLand, WebStorm), and any other tool that supports the Model Context Protocol. New integrations ship regularly.
Is Fivo Cell free?
Yes. Fivo Cell is Apache 2.0 open source, forever free. No subscription, no per-seat pricing, no usage limits. The companion cloud service (Fivo Cell Cloud) has a free personal tier and paid team tiers for cross-device sync.
Does Fivo Cell send my code to the cloud?
No. Fivo Cell is local-first with zero telemetry. All style data stays on your machine unless you explicitly opt in to Fivo Cell Cloud sync, which is encrypted with AES-256 and JWT.
How is Fivo Cell different from Cursor rules?
Cursor rules require you to manually write what you want. Fivo Cell observes your edits and learns your style automatically. No rules, no maintenance, no drift.
What is Fivo Cell Cloud?
Fivo Cell Cloud is the hosted sync layer for Fivo Cell OSS. It runs at cell.fivo.live, captures AI sessions from your local daemon, and unlocks cross-device intelligence plus a 12-page dashboard. Personal tier is free forever.
