Best for internal automation and customer-facing assistants with mixed text+voice surfaces. Pricing: see vendor pricing.
What it is
Stack AI is a workflow builder that chains LLMs, vector stores, tools, and APIs into deployable assistants. Voice agents are one supported output channel, layered over Twilio or Vapi for PSTN delivery. Stack AI positions toward enterprise IT and operations teams that need quick wins across knowledge bots, RAG search, and lightweight phone assistants.
Watch out for: Voice features lighter than dedicated voice-AI vendors; favors chat workflows.

Alternatives to Stack AI
Frequently asked about Stack AI
How much does Stack AI cost?
Stack AI does not publish a self-serve price — it is quoted by the vendor on contact. Expect an enterprise-style agreement rather than a card-and-go signup.
Does Stack AI work on Mac, Windows and Linux?
Stack AI runs on Web and Cloud. It is not listed for other platforms; check the vendor for anything beyond Web and Cloud.
What are the limitations of Stack AI?
Voice features lighter than dedicated voice-AI vendors; favors chat workflows.
Who is Stack AI best for?
Internal automation and customer-facing assistants with mixed text+voice surfaces.
Is Stack AI open source?
No. Stack AI is a proprietary product. If you need source you can read and run yourself, the open-source tools in this directory are the place to look.
What kind of tool is Stack AI?

What are the alternatives to Stack AI?
There is a side-by-side page at /tools/stack-ai-alternatives comparing Stack AI with the closest tools in the same category on price, platform and features.
Can I automate Stack AI-style transcription without running it myself?
Yes. If what you want is transcripts rather than the tool itself, Whipscribe does the same job as a hosted API: submit a file or URL, poll a job id, pull the result as txt, json, srt, vtt or docx. $0.012 a minute — about $0.72 an audio hour — bought as credits that never expire. The automation recipes on this site show it wired to Drive folders, Zoom recordings, S3 buckets and no-code platforms.
How is Whipscribe different from Stack AI?
Stack AI is another vendor's product; Whipscribe is a per-minute transcription service. Recordings are transcribed on our own servers and never used for training, and every job returns five formats plus an AI summary, quotes and topics. The first 20 minutes of any recording are transcribed free, and a pack from $6 (500 minutes) transcribes the rest and opens every export.
What does transcription cost if I use Whipscribe instead of Stack AI?
$0.012 a minute — about $0.72 an audio hour — bought as credits that never expire. There is no subscription and no monthly minimum: a 3-hour recording is about $2.16, a thousand-hour archive is about $720 once. The first 20 minutes of any recording are transcribed free, and a pack from $6 (500 minutes) transcribes the rest and opens every export, so you can see what your recording holds before paying anything.
Where is the Stack AI category heading?
Three things are moving across the whole speech-to-text market right now: summaries, action items and speaker insights generated on top of the transcript rather than sold separately; private, secured deployment where the audio never leaves a boundary you control; and agent access — transcription exposed as a tool that Claude, Cursor or a workflow runner can call directly. Whipscribe ships all three today: per-job insights, our own servers, and an MCP server.
Whipscribe is a hosted transcription service. If you want transcripts without running infrastructure, paste a URL or drop a file in the form below — you'll have a transcript in seconds.
