>What Makes DYNOBOX Different?
~Gmail, Outlook, iCloud — every account unified into one fast interface with universal search.
~AI sorts your inbox automatically. Newsletters, receipts, alerts — categorised so only what matters reaches you.
~Brain Box is being shaped in the open: local models, BYOK providers, and transparent AI workflows.
>Can I Contribute?
~Yes. Themes, MCP integrations, SDK examples, docs, and issue reports are all part of the public development path.
// what it does
06 features
unify()
All inboxes, one place
Gmail, Outlook, iCloud — every account pulled into a single, fast interface. No more tab-switching. No more missed threads.
search()
Universal search
One query. Every inbox. Find any email, attachment, or thread in milliseconds — across all your connected accounts at once.
sort()
Smart categories
AI learns your signal from your noise. Newsletters, receipts, alerts — automatically sorted so your inbox only shows what actually needs you.
ask()
AI built in
Triage, draft, and summarise with transparent AI workflows. Run local models with Ollama or bring your own key for Claude, GPT, or any OpenAI-compatible provider.
extend()
Built to be extended
MCP integration, an open SDK, and public extension points are part of the open-source roadmap. Connect DYNOBOX to your tools, automate workflows, and help shape what comes next.
theme()
Make it yours
Ships with multiple polished themes out of the box. Want something bespoke? Build and apply your own — full control over every detail.

Brain Box

Built-in intelligence.
No setup required.

Brain Box is the AI layer embedded in every DYNOBOX account. It understands your email at a semantic level — across every inbox, automatically.

~Semantic search — find anything across all accounts with natural language
~Auto-tagging — labels applied intelligently based on content and context
~Intent detection — knows what an email actually wants from you
~Reply suggestions — draft responses in your voice with one click
~Thread summarisation — get the gist of any long chain instantly
~Task extraction — surfaces action items before you even open an email
~Follow-up detection — flags threads waiting on your reply
~Zero Data Retention models — choose from providers that guarantee your data is never stored or trained on

Your AI. Your box.

Brain Box can be switched to run on a local model, like Ollama — keeping all processing on-device and under your complete control. No API keys, no usage metering, nothing leaves your machine.

~Full privacy — all inference runs locally — no data sent externally
~Any Ollama model — llama, mistral, gemma, qwen — swap at any time
~Zero API cost — no tokens, no metering, no subscriptions
~Offline-capable — Brain Box keeps working even without internet

Extend. Build.
Your own DYNO.

DYNOBOX is built to be extended. Connect it to any tool in your stack via MCP, or use the SDK to build full mail-driven applications on top of it — automations, custom pipelines, anything your workflow demands.

~MCP integration — connect DYNOBOX to any MCP-compatible tool or service
~Mail-driven apps — trigger custom workflows and automations from email events
~Open SDKsoon — build full applications on top of DYNOBOX
~Plugin systemsoon — extend the UI and AI layer with your own modules
Your inbox should be yours.
So should the tools around it.
DYNOBOX is opening up.

The project is moving away from pricing-tier promises and toward open-source development: inspectable code, public roadmap decisions, community-built integrations, and AI workflows you can run on your own terms.
