Developer Intelligence

All signal.
No feed.

Your codebase decides what's relevant. Everything else is rejected.

GitHub, YouTube, Hacker News, Reddit, arXiv, and 5 more sources — scored on 5 axes against your actual stack. 2+ signals required to pass.

Automatic Context Discovery

Scans your Cargo.toml, package.json, go.mod, and pyproject.toml. Builds a graduated domain profile from your actual stack — no manual configuration.

Multi-Signal Confirmation Gate

Every item is scored across 5 independent axes. An item needs 2+ confirming signals to pass the gate. Typical rejection rate: 99%+ of incoming content.

Privacy by Architecture

Raw data never leaves your machine. BYOK for AI features. Zero telemetry. Full offline mode with Ollama. Architecturally unable to see your data.

What You Get

Intelligence, not information

scoring

Scored Feed

Every item scored on 5 axes against your codebase. See exactly why something matters to you.

identity

Developer DNA

Your tech stack, dependencies, and interests as a shareable profile. Exportable as SVG badge.

briefing

Daily Briefing

AI-synthesized digest of what matters today. Signal chains show cause and effect across sources.

The Problem

Staying current is a full-time job

The average developer spends 2+ hours daily on content consumption. Signal-to-noise ratio: less than 2%. That's 500+ hours a year reading things that don't matter to your work.

Signal
Only what matters
An item needs 2+ independent signals to pass the confirmation gate. Everything else is rejected.

Context Axis

KNN embedding similarity against your codebase profile via sqlite-vec vectors.

Interest Axis

Keyword + semantic alignment with your declared and observed interests.

ACE Axis

Does this involve your active technologies, frameworks, and architecture patterns?

Dependency Axis

Direct match against your installed packages. Version bumps, CVEs, deprecations.

Features

Everything noise reduction needs

Every feature exists to reduce noise and surface what actually matters to your work.

scoring

5-Axis Scoring

Context, Interest, ACE, Dependency, and Learned axes independently evaluate every item. Multi-signal confirmation gate rejects 99%+ of incoming content.

privacy

Privacy First

All data stays on your machine. Raw content never leaves. BYOK for Anthropic, OpenAI, or fully local with Ollama. Zero telemetry. Transparent cost tracking.

context

Auto Context Discovery

Scans your Cargo.toml, package.json, go.mod, and Git activity to build a graduated domain profile of your technology identity.

MCP Integration

Your AI assistant gets signal too

4DA ships an MCP server with 30 intelligence tools. Install it with one command and your AI assistant draws from your scored, filtered intelligence feed -- not generic internet search results.

Works with Claude Code, Cursor, and any MCP-compatible host. MIT licensed. Always free.

  • "What breaking changes affect my deps this week?"
  • "Give me my daily briefing"
  • "What knowledge gaps does my project have?"
  • "Show signal chains for the Tokio update"
// Install -- one command
npx @4da/mcp-server

FAQ

Common questions

How is this different from daily.dev or Feedly?
daily.dev personalizes by engagement (what you click). Feedly aggregates by subscription (what feeds you add). 4DA scores by relevance to your actual codebase -- your Cargo.toml, package.json, and Git activity define the filter. It's categorically different: project-aware scoring instead of behavioral or topical filtering.
Does 4DA read my source code?
4DA reads manifest files (Cargo.toml, package.json, go.mod, etc.) and Git metadata to build your technology profile. It does not read your actual source code files. The profile is built and stored locally -- nothing leaves your machine.
Can I use it without any API keys?
Yes. The free tier works entirely without API keys. For AI-powered features (daily briefings, score autopsy), you can use Ollama for fully local inference or provide your own API key (BYOK) for Anthropic or OpenAI.
What happens if I never pay?
Nothing changes. The free tier includes all 10 sources, the full 5-axis scoring engine, behavior learning, the MCP server with 30 tools, the complete STREETS Playbook (all 7 modules), and the CLI. The free tier never expires. Pro features include a 30-day free trial so you can evaluate before subscribing. Most individual developers will never need Pro.
What's the confirmation gate?
The confirmation gate requires 2+ independent scoring axes to agree before an item enters your feed. A single keyword match isn't enough. A single interest match isn't enough. Independent confirmation from multiple relevance dimensions is required. This is what makes the 99%+ rejection rate possible.
How big is the download?
About 15MB. 4DA is built with Tauri 2.0 (Rust), not Electron. Pre-built binaries with auto-updates for Windows, macOS, and Linux.
Is it open source?
Source available under FSL-1.1-Apache-2.0. You can read, audit, and self-host. The license converts to Apache 2.0 (full open source) after 2 years. The MCP server is MIT licensed.
