Memos vs Double

Memos vs Double: at a glance
What is Memos?
Memos adds collaborative Spaces without handing administrators the keys to everyone's notes.
Memos is a self-hosted memo archive that has spent three release candidates rebuilding its foundations rather than its surface. 0.27 embedded an MCP server in the instance, 0.30 flipped undeclared instances to private mode and regenerated that MCP surface from the OpenAPI schema, and 0.31.0-rc.1 now introduces first-class Spaces with ADMIN and USER memberships. The ownership model was rewritten alongside it: instance administrators are no longer implicit collaborators on other people's memos.
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.

Memos
3.8COLLAB
Memos adds collaborative Spaces without handing administrators the keys to everyone's notes.
◆ Current state
Memos is a self-hosted memo archive that has spent three release candidates rebuilding its foundations rather than its surface. 0.27 embedded an MCP server in the instance, 0.30 flipped undeclared instances to private mode and regenerated that MCP surface from the OpenAPI schema, and 0.31.0-rc.1 now introduces first-class Spaces with ADMIN and USER memberships. The ownership model was rewritten alongside it: instance administrators are no longer implicit collaborators on other people's memos.
◆ Where it's heading
The direction runs from one person's notebook toward shared, agent-addressable infrastructure, and the order matters — access control and a stable API surface landed before multi-user sharing did. Each candidate has carried its breaking changes rather than deferring them: Shortcuts became Saved Views across the API, MCP tools and web routes, reactions lost content_id, S3 attachments stopped returning presigned URLs, and the Explore and per-user RSS feeds now return 404. Memos is willing to spend client compatibility to keep the data model coherent.
◆ Prediction
Expect 0.31 to reach a stable release with migration guidance for the Saved Views rename, and for Space scoping to extend next to the surfaces the notes say stay global — Archived, Inbox, profiles and Settings.
Double

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.
