Welvo is a desktop application that archives your emails on your own computer and lets you ask the archive questions in natural language. It downloads your IMAP accounts along with attachments, offers AI-powered semantic search alongside classic keyword search, and links every answer back to the source emails. Data stays on the device; no cloud account is required to set it up.
Every Welvo capability, in short.
Add your IMAP accounts (Gmail, Outlook/Microsoft 365, Yahoo, Yandex, corporate servers) and download them folder by folder; new mail keeps syncing in the background.
Every message is stored with its attachments in the open .eml format — never locked into a closed container, and exportable any time.
The archive location can be a local disk or a network share (NAS); the setting is per device, while the database always stays local.
Scans and previews old Outlook archives, then adds them as a separate account with your approval; the same message is never imported twice.
Restores local archive messages back to the same account (recovery) or a different one (migration); a dry run shows what will happen first.
Moves messages directly between two IMAP servers by folder, skipping duplicates.
Full-text search across subject, sender and body. Case- and Turkish-character-insensitive, no extra download required.
Ask sentences like “What was Jane Doe working on before she left?” — Welvo scans the archive and summarizes the answer.
Every answer lists the numbered emails it used; click one to open and verify the original.
Finds relevant emails even without an exact keyword match, using the bundled local model or your own server/cloud provider.
An optional second local model reorders candidate sources to improve answer accuracy.
Text inside PDF, Word and Excel attachments is extracted and made searchable; image attachments are described if a local model is installed.
Say “put these threads into a table” and get results as an Excel, Word or PDF report.
Recognizes newsletters and marketing mail by their headers so you can exclude them from search and Q&A.
Star important emails, add private notes, and keep your chat history and generated reports on record.
Email content never leaves your computer by default. Connecting a cloud provider requires your explicit consent and a clear warning.
Super admin and standard user roles with per-user account access and sharing — you decide who sees which archive.
Account passwords are stored in the operating system’s credential vault; each account gets a single-use recovery code.
Works with a zero-setup embedded database, or connect your own PostgreSQL server if you prefer.
The same experience on both platforms; installation is a single file with no extra server or service required.
Language is chosen on first launch, stored per user, and changeable from Settings.
From setup to your first answer.
Add your IMAP account with your email and app password; server settings auto-fill for known providers.
Mail is downloaded to your computer with attachments and made searchable. This runs in the background.
Search by keyword, or ask AI Mail Search a sentence — the answer arrives with its source emails.
Turn the result into an Excel/Word/PDF report, or restore messages back to a server if needed.
Anywhere email carries contracts, quotes and instructions.
Find quotes, proformas, bills of lading and customs correspondence in seconds, even years later.
Keep client correspondence and submitted documents in one archive, and show the source during an audit.
Trace which email a contract version came from, and who sent it, with the source attached.
Search order, deadline and lot correspondence together with the content of their attachments.
Pull up what a departing employee was working on and their open items with a single question before handover.
Never lose a message deleted when the server quota fills up — the archive stays with you.
Archiving, search and Q&A run on your computer. Email content is never sent to a server; Welvo doesn’t require an account or an internet connection to work.
If you want a more powerful model, you can connect your own server or cloud provider. This happens through an explicit consent screen that states clearly what will be sent — the decision is always yours.
Note: Welvo is an archiving and search tool; data-protection compliance, retention periods and access rights are configured according to your organization’s policies. Per-user access and sharing controls support this.

The most common questions about Welvo, answered briefly.
It stores your emails on your own device, independent of the server. When the server quota fills up or an account is closed, nothing is lost — you can still search, report, and restore to a server when needed.
No. Archiving, search and Q&A run on your computer by default. Content is only sent to a cloud provider if you explicitly consent and connect one yourself for that specific action.
You write your question as a sentence. Welvo searches the archive for relevant correspondence, summarizes the answer, and numbers the emails it used. You can click any citation to verify it.
Yes. Welvo scans the PST/OST file, previews how many folders and messages it contains, and adds it as a separate archive account with your approval. The same message is never imported twice.
Yes. You can restore from the local archive to the same account (recovery) or a different one (migration). A dry run shows what will be uploaded before anything happens.
Yes. Text inside PDF, Word and Excel attachments is extracted and made searchable; image attachments are indexed along with their content if a local description model is installed.
The installation runs on a device license, and each user takes one seat. The super admin adds users, sets roles, and manages which account is visible to whom.
Your archive and search work fully offline. Internet is only needed to download new mail from the server and for optional model downloads.
The app installs from a single file and ships with an embedded database, so no separate server setup is needed. How long the archive takes to download depends on the size of your mailbox, and it runs in the background.
Let’s work out together how many accounts to archive, your retention period and user count — we’ll handle the setup.
