Once registered, Tiro references this word during voice transcription to improve recognition accuracy. Useful for proper nouns, technical terms, or any word that standard speech-to-text may not recognize correctly. Duplicate entries (same `entry` value) are not allowed and will return `409 Conflict`. ## OpenAPI ````yaml /openapi.yaml post /v1/external/users/me/word-memories openapi: 3.1.0 info: title: Tiro API description: AI-powered note-taking and voice file processing API version: 1.0.0 contact: name: Tiro Support email: support@tiro.ooo url: https://tiro.ooo servers: - url: https://api.tiro.ooo description: Production server security: - BearerAuth: [] tags: - name: Note description: Operations for managing notes and their paragraphs - name: Note Share Link description: Manage share links for notes - name: Note Summary description: Operations for retrieving note summaries - name: Note Document description: Template-based document generation from notes - name: Note Document Template description: Operations for managing note document templates - name: Folder description: Operations for retrieving folders - name: Voice File description: Operations for voice file processing - name: Word Memory description: > Manage word memories to improve voice transcription accuracy. Register important terms like company names, people's names, and product names so Tiro recognizes them precisely during recording. Personal word memories (User) and a workspace's shared word memories (Workspace) are managed separately. The legacy team word memory endpoints (`/v1/external/teams/me/word-memories`) are deprecated — removed on 2026-06-30 — in favor of the workspace-explicit `/v1/external/workspaces/{workspaceGuid}/word-memories`. - name: Wiki description: | Access workspace wikis — unified knowledge graphs built from notes. Requires a workspace with wiki plan and activation enabled. - name: Organization description: > Endpoints for organization API keys. An organization key is issued by an organization admin, carries fixed scopes chosen at issuance, and can reach the notes in every workspace that belongs to the organization. Built for server-to-server integrations such as CRM sync — receive `note.ended` webhook events, generate documents for notes, and reconcile with the organization notes list. - name: Organization Management description: Operations for the authenticated user's organization. paths: /v1/external/users/me/word-memories: post: tags: - Word Memory summary: Create User Word Memory description: > Register a new word to the user's personal word memory.

Use only when you need to distinguish specific error cases within the same HTTP status — values may be added or renumbered across releases. For general client branching, prefer `errorType`. example: 404018 errorType: type: string description: > Stable, coarse-grained error category. Recommended default for client-side branching: the value-to-status mapping is part of the API contract and will not change without a breaking-change notice. Typical use: - `unauthorized` → trigger re-authentication - `forbidden` → surface a permission error to the user - `not_found` → treat as missing resource - `too_many_requests` → back off and retry - `internal_error` → retry with exponential backoff enum: - bad_request - unauthorized - forbidden - not_found - not_acceptable - conflict - payload_too_large - unprocessable_entity - too_many_requests - internal_error example: not_found message: type: string description: >- Human-readable error message.
