Trilium Notes vs Double
A side-by-side editorial comparison of Trilium Notes and Double — release velocity, themes, recent moves, and the top alternatives to consider.
Trilium Notes vs Double: at a glance
What is Trilium Notes?
Trilium spent a year adding what notes can hold; now it is fixing what happens to them.
Trilium Notes is a self-hosted hierarchical note application with an unusually broad content model — text, code, canvases, mind maps, and since 0.103.0 spreadsheets with formulas and OCR-extracted text from images, PDFs and Office files. Releases are large, quarterly, and explicit about breakage. The current release turns that attention inward: the database itself becomes something you can measure, clean, repair, and restore.
What is Double?
Double restructures AI pricing with a 93%-cheaper Standard tier, making Ask Double viable at full-book scale
Double is an AI-first accounting platform built for accounting firms managing multiple clients. Over the past two months the product has aggressively extended its Ask Double AI assistant — building workpapers, importing accruals, managing metrics, routing bank transactions from raw PDFs, and now auto-routing queries across a three-tier model stack. The Sep 10 model restructuring is the culmination: with a Standard tier 93% cheaper than Expert and an Auto mode that routes per-query complexity, Double has shifted AI accounting from a premium add-on into an economically viable default across every client account. The interactive financial statement suite — P&L, Balance Sheet, and Cash Flow — is now complete.

Trilium Notes
6.3COLLAB
Trilium spent a year adding what notes can hold; now it is fixing what happens to them.
◆ Current state
Trilium Notes is a self-hosted hierarchical note application with an unusually broad content model — text, code, canvases, mind maps, and since 0.103.0 spreadsheets with formulas and OCR-extracted text from images, PDFs and Office files. Releases are large, quarterly, and explicit about breakage. The current release turns that attention inward: the database itself becomes something you can measure, clean, repair, and restore.
◆ Where it's heading
Two arcs run in parallel. One expands what a note can be, peaking with the spreadsheet note type and OCR that feeds extracted text into search. The other is about trust in the thing holding your knowledge base — a coordinated security release in April, then 0.105.0 shipping backup restore, a cleanup tool that honours versioning limits, compaction, integrity repair, and a space-usage treemap. The AI layer is being made self-hostable in the same spirit, moving from a fixed vendor model list to dynamic retrieval plus Ollama, LM Studio and any OpenAI-compatible provider. Breaking changes are frequent and documented up front rather than smuggled in.
◆ Prediction
The two features the maintainer explicitly links to funding — an official mobile application and multi-user support — are the stated backlog; nearer term, expect the spreadsheet note type to leave beta and the newly networked MCP interface to gain more surface.
Double
6.3COLLAB
Double restructures AI pricing with a 93%-cheaper Standard tier, making Ask Double viable at full-book scale
◆ Current state
Double is an AI-first accounting platform built for accounting firms managing multiple clients. Over the past two months the product has aggressively extended its Ask Double AI assistant — building workpapers, importing accruals, managing metrics, routing bank transactions from raw PDFs, and now auto-routing queries across a three-tier model stack. The Sep 10 model restructuring is the culmination: with a Standard tier 93% cheaper than Expert and an Auto mode that routes per-query complexity, Double has shifted AI accounting from a premium add-on into an economically viable default across every client account. The interactive financial statement suite — P&L, Balance Sheet, and Cash Flow — is now complete.
◆ Where it's heading
Double is building toward a full AI-agent accounting platform, not just a chat interface bolted onto bookkeeping software. The AI Agents private beta (automating recurring tasks on a schedule or event trigger), the MCP/API surface for programmatic control, and the Connections feature (reaching into Slack, Notion, HubSpot) all point to Double becoming an orchestration layer for accounting firms. The model pricing restructure signals that Ask Double is expected to run on virtually every client action, with human review reserved for exceptions rather than the default. The direction is clear: make AI the primary work surface and treat the accounting firm's judgment as the final gate.
◆ Prediction
The next move is most likely graduating the AI Agents beta to general availability — converting scheduled automation and event-trigger workflows from a differentiated beta into a standard tier feature. Expansion of the Connections library beyond Slack, Notion, and HubSpot is also probable, since cross-tool context is a prerequisite for agents to make decisions autonomously.
