What Mentat Has
Real tools of its own, and what it can do with them
Standard chat assistants only output text. Mentat has its own computer, browser, and phone lines so it can actually do the work.
1. A computer for coding & live apps
Mentat has a cloud Linux computer with a terminal, file system, and developer tools. With its computer it can:
- Write code & host live web dashboards: Build custom trackers, calculators, and databases, and send you a live URL.
- Run scheduled scripts 24/7: Keep background jobs running in the cloud even when your laptop is closed.
2. Video editing, presentations & PDFs
Because it has a full computer with media and document packages installed, you can send it raw files on WhatsApp and it can:
- Edit videos & audio clips: Trim dead air, burn in subtitles, convert formats, and transcribe or translate voice notes.
- Build presentations & printable PDFs: Turn rough notes or photos into slide decks, worksheets, check-in sheets, and Excel files.
3. A browser of its own
Mentat controls a real web browser on its cloud machine. With its browser it can:
- Log into portals & fill forms: Navigate websites, complete multi-step forms, and pull data from portals that have no API.
- Check live availability & prices: Look up tickets, flights, restaurants, and local listings across the web and return clean links.
4. Phone & WhatsApp lines of its own
Start chatting with Mentat 1-on-1 immediately, or attach a dedicated phone and WhatsApp number so it can:
- Place real phone calls & SMS: Call clinics or businesses to book appointments, call you for morning briefings, and text contacts from its own number.
- Join family & team WhatsApp groups: Act as a shared concierge with your partner or team, tracking shared to-dos and sending reminders.

Simple & Strict Security
Full power for you. Approval gates for everyone else.
Mentat is built so you can safely add it to group chats and let it talk to external contacts without risking your data or credentials.
Talking to the admin: all is allowed
When you message Mentat directly from your admin account, every tool is unlocked. It runs code, spins up computers, and uses your connected integrations right away with zero friction.
Other conversations: sensitive actions trigger approval
In group chats or when someone else messages your bot, normal conversation works freely, but anything sensitive (like running code, spinning up a VM, or accessing credentials) automatically pauses and sends a 1-tap approval link to your WhatsApp.
Secrets are encrypted at rest
Every API key, OAuth token, and credential you connect is encrypted at rest before touching the database. Raw secrets never sit in plaintext on disk or inside chat history.
Open Source Core
Powered by the open-source prompt2bot harness
Mentat runs on the open-source prompt2bot agent harness. You can inspect the execution loop, multi-channel adapters, sandboxed secret handling, and assistant skills directly on GitHub.
Simple, Transparent Pricing
Prices are in USD. Paid plans renew monthly. Pause or cancel anytime in Settings or via the AI Builder, and your bots, prompts, and chat history are never deleted.
An LLM run is one AI model call. One message or task can use multiple runs.
Recurring scheduled actions require a paid plan.
