Stack AI hands you a canvas. Fasrad hands you a working agent.

Building the workflow vs. having the work done

Stack AI is a visual builder. You drag nodes onto a canvas, connect an LLM to a vector store to an API call, test the flow, and ship it as an internal tool or chat assistant. It's a serious platform for teams that want to design repeatable AI workflows with versioning, RBAC, and on-prem options. If your IT department wants to own the pipeline and audit every step, that's exactly the right shape.

Fasrad starts after the part Stack AI is built for. There's no canvas. You tell the agent, in a plain sentence, what you want handled — "every weekday at 7am pull my unread invoices, log them in a sheet, and flag anything over 5,000" — and it runs on its own schedule, on infrastructure we host. The agent already has an email inbox, a calendar, a CRM, datastores, web browsing, and cron-style triggers. You're not assembling those capabilities into a graph; you're handing the agent a job.

Where the line falls:

• Stack AI wins when you need to design and version a precise multi-step pipeline with explicit branching, deploy it as a governed internal app, and keep it inside your own VPC — Fasrad has no node editor and no on-prem deployment.
• Fasrad wins when the value is the work getting done, not the diagram — drafting the reply, booking the slot, filing the row — and you'd rather write a sentence than wire a flow.
• Stack AI is built for teams shipping AI features to other people; Fasrad is an operator that does your own work across email, calendar, and CRM.
• Fasrad runs hosted and acts unprompted on triggers and schedules; nothing to build, deploy, or babysit after a ~4-minute setup.

Pick Stack AI if you're an enterprise team productizing AI workflows and need a governed builder you control end to end. Pick Fasrad if you want one agent that quietly works your inbox, calendar, and contacts without you ever opening an editor.

• AI Personal Assistant — Your calendar, your follow-ups, your morning brief — run by an assistant with its own inbox, so you stop being your own secretary.
• AI Virtual Assistant — An assistant that does the work, not just the chat: its own inbox and calendar, your meetings booked, the replies you’d forget chased down.
• AI Booking Bot for Websites — Turns a website visitor into a booked meeting: it qualifies the request, offers real availability, books your calendar, and hands you the notes.
• AI Website Chatbot for Your Site — Closes the loop instead of dropping a transcript: it answers from your real pages, captures the lead, and books the meeting.
• AI Cold Outreach Agent — Personalizing cold email at volume is a full-time job; a blast just burns your domain. The agent does both — and books the replies — so you only show up for the meeting.
• AI Research Analyst — Hand it a question and a deadline, get a brief that shows its work — figures, links, and the page each number came from.
• Notion Alternative — Notion is brilliant storage; someone still has to dig through it. Fasrad reads every page and answers from the right doc — no tabs, no digging.
• Calendly Alternative That Reads & Replies — A booking link can’t read the email it’s pasted into. Fasrad can — it proposes the slot that fits, books it, and briefs you before you walk in.

Frequently asked questions

Is Fasrad a workflow builder like Stack AI?

No. Stack AI gives you a canvas to design and version multi-step agent workflows. Fasrad has no canvas — you describe the task in plain language and a hosted agent runs it across its email, calendar, CRM, and datastores. If you want to draw and govern the pipeline yourself, Stack AI is the better fit.

What does Stack AI still do better?

Plenty. Stack AI is built for enterprise teams shipping AI features: explicit branching logic, version control, role-based access, and self-hosted or VPC deployment so your data never leaves your environment. Fasrad has no node editor and runs only on our hosted infrastructure. If you need to own the pipeline end to end or keep everything on-prem, choose Stack AI.

Can Fasrad run scheduled and triggered tasks like a Stack AI workflow?

Yes. You set cron-style schedules ("every weekday at 7am") and event triggers (new email, new public message, captured lead) by describing them in a sentence. The agent runs them on its own and checks in with what it did — no flow to deploy or monitor.

Do I need to connect a vector store or set up retrieval?

No. Fasrad's agent creates and queries its own private datastores, and uses hybrid retrieval for long-term memory internally. There's nothing to wire up. In Stack AI you'd configure those components yourself, which is the point of a builder.

What can't Fasrad do?

It doesn't transcribe live calls or audio, make phone calls, or do video. It also can't be self-hosted and has no visual flow editor. It works through text and structured actions: reading and writing email, booking calendar events, updating a CRM, browsing the web, and calling APIs.

How much does it cost?

$49/month or $490/year — cancel anytime. Setup takes about four minutes — connect Google, describe the job, and the agent starts. Fasrad is in public beta.
