Capacities vs Paperless-ngx: at a glance
What is Capacities?
Capacities is becoming an AI-connected knowledge hub with a real developer API.
Capacities, a note-and-object-based personal knowledge tool, is shipping fast — roughly biweekly releases — and pushing two frontiers at once: opening the app to outside systems and deepening its own AI. It now has AI Chat Connectors to ChatGPT, Claude, and Cursor, an on-device Search 3.0, image analysis, recurring tasks, and a choice of AI model provider.
What is Paperless-ngx?
Paperless-ngx v3 turns a self-hosted document archive into an AI you can query
Paperless-ngx, the self-hosted document manager, is deep in its v3.0.0 beta. The stable 2.20.x line is now pure maintenance, shipping security patches and bug fixes, while every new capability lands in the v3 betas: a built-in AI layer, a tantivy search backend replacing Whoosh, document versioning, and a parser plugin framework, alongside a wall of breaking changes.

Capacities is becoming an AI-connected knowledge hub with a real developer API.
◆ Current state
Capacities, a note-and-object-based personal knowledge tool, is shipping fast — roughly biweekly releases — and pushing two frontiers at once: opening the app to outside systems and deepening its own AI. It now has AI Chat Connectors to ChatGPT, Claude, and Cursor, an on-device Search 3.0, image analysis, recurring tasks, and a choice of AI model provider.
◆ Where it's heading
The arc is Capacities moving from a closed personal tool toward a platform: API 2.0 gives developers programmatic access, while the AI Chat Connectors let external assistants read and increasingly write into a user's space. Its AI work emphasizes user control — local-first search, choose-your-model — rather than a single hosted assistant. Cadence is high and consistent.
◆ Prediction
With the API opened and connectors moving from read to write, the likely next step is a richer integration surface — third-party tools and agents building on the API — plus more of what connected AI apps can create inside a space.

Paperless-ngx v3 turns a self-hosted document archive into an AI you can query
◆ Current state
Paperless-ngx, the self-hosted document manager, is deep in its v3.0.0 beta. The stable 2.20.x line is now pure maintenance, shipping security patches and bug fixes, while every new capability lands in the v3 betas: a built-in AI layer, a tantivy search backend replacing Whoosh, document versioning, and a parser plugin framework, alongside a wall of breaking changes.
◆ Where it's heading
The project is converging v3 toward release-candidate stability. rc2 is mostly dependency bumps, an Angular 22 upgrade, and AI-search hardening (sqlite-vec, ollama embeddings, LLM timeouts) rather than new direction. The directional bet, local retrieval over your own documents, is set; the work now is making it reliable on small self-hosted installs.
◆ Prediction
A v3.0.0 stable release is the next milestone once the AI indexing and tantivy search settle; expect continued fixes around memory use and embedding quality before the beta tag drops.
