FAQ¶

The most frequent questions about Myeline on-prem editions.

General¶

What's the difference between sovereign and sovereign-hybrid?¶

Sovereign: 100 % air-gap, no outbound calls technically possible. AI synthesis runs locally via Ollama.
Sovereign-hybrid: air-gap by default, but each organisation can enable an external AI provider (Mistral / Claude / OpenAI / Gemini) with its own key (BYOK).

Can I migrate between the two?¶

Yes, with no data loss. Change DEPLOYMENT_MODE in .env, provide the new licence key for the desired tier, restart.

How much does the licence cost?¶

On quote, depending on number of users and scope. Contact hello@myeline.io. Licences are annual, 12 months max (no perpetual licence is issuable, by construction).

Is there a "trial" mode?¶

Yes — 30-day evaluation licence, request via the same channel. Covers all hybrid-tier features.

Data¶

Does my data leave my network?¶

Sovereign: no, never. No outbound call is technically possible.
Sovereign-hybrid: only if you explicitly enable an external AI provider. In that case, the question text + relevant chunks transit to the provider on every query. Documents and embeddings always stay on your infra.

Details: Data residency.

What database size can I handle?¶

Order of magnitude on standard sizings:

Volume	Recommended setup
≤ 100k documents	32 GB RAM, NVMe, optional GPU
100k - 1M documents	64 GB RAM, GPU 24 GB, striped NVMe
> 1M documents	ChromaDB sharding + dedicated Ollama cluster

See Server prerequisites.

GDPR: yes, by construction (encryption, pseudonymisation, audit, configurable retention, right to erasure).
HDS: Myeline itself is not HDS-certified — certification is on the host. In sovereign mode, you are the host: if your infra is HDS-certified, your Myeline deployment is.

Details: GDPR compliance.

Features¶

Can I use GPT-4 or Claude?¶

Sovereign: no.
Sovereign-hybrid: yes, via BYOK. Each organisation picks its provider and supplies its own API key. No AI cost via Myeline — you pay the provider directly.

Which document formats are supported?¶

PDF, DOCX, ODT, TXT, MD, HTML, CSV. See Library and uploads.

OCR on scanned PDFs is disabled by default — enable via RAG_OCR_ENABLED=true (sovereign-hybrid only, Tesseract dependency).

Is there a manual file upload?¶

No, not at all — neither personal nor organisation side. The library (personal or shared) is filled exclusively via:

Cloud connectors: Google Drive, OneDrive, Dropbox, kDrive, Zotero, S3 / S3-compatible, WebDAV
RSS / web scrapers

This is a design choice (single source of truth on the customer side, compliance, simple ingestion path) — see Library § Why no manual upload?.

How many concurrent users?¶

Without hardware bottleneck: several hundred on a properly-sized infra. The typical bottleneck is Ollama (AI synthesis) on a single GPU — beyond ~20-30 active concurrent users, plan a GPU cluster or switch to BYOK in sovereign-hybrid.

Does multi-tenant work on-prem?¶

Yes. One Myeline instance can host multiple organisations, each with its own ChromaDB collection, users, OIDC, AI provider (in sovereign-hybrid). Organisations are strictly isolated.

Operations¶

How often should I update?¶

Security patches: within 7 days of release.
Minor releases: per your maintenance window.
Major releases (rare): 30 days notice, opportunity to track release candidates in a pre-prod environment.

See Upgrade.

How do I back up?¶

Automatic daily cron at 02:30 (DB + ChromaDB + uploads). Off-host recommended via rclone / MinIO / borg. See Backup and restore.

Can I integrate Myeline with my enterprise SSO?¶

Yes — OIDC (Azure AD, Okta, Keycloak, Authentik, any standard IdP). See Enterprise SSO.

Is there a public API?¶

No formally-exposed REST API to end-users in current editions. Admins have access to internal endpoints (/admin/*, /metrics, /healthz), and Flask blueprints are introspectable if you want to script internally.

A public API (REST + OpenAPI) is on the roadmap for Q4 2026.

Support¶

What's the SLA?¶

The SLA and detailed support conditions are specified in the licence contract signed with your organisation.

Where do I ask a question?¶

Email: hello@myeline.io
For reproducible bugs: attach a /health snapshot + last 50 web log lines.

Can I access the source code?¶

Yes in sovereign-hybrid under escrow and on specific request (commercial clauses). Myeline source is not public open-source but the publisher can provide a read-only repository for client-side security audit.
