## Shortlist

### 1. Faceless.so

AI writes, voices and edits faceless short videos, then auto-posts them to seven social platforms on a schedule.

**Where it improves on ImageToSTL:**
- [Runs autonomously: yes — A Series generates and posts episodes on a schedule with no human in the loop, though the vendor also lets you approve, edit or skip each video before it goes out.](https://faceless.so/pricing)
- [API access: partial — A versioned REST API with scoped keys, idempotency and typed errors is fully documented, but the plan comparison grants API access only on Ultra and Agency, not on the three cheaper tiers.](https://faceless.so/developers)
- [Seat model: partial — Seats are bundled, not priced per head: each tier includes a fixed ceiling of team members from 3 on Starter to 25 on Agency, and no page offers buying extra seats.](https://faceless.so/pricing)

**Trade-offs against ImageToSTL:**
- [Free tier: partial — You can sign up and buy a plan yourself with no sales call, but the pricing FAQ says outright there is no free trial, so nothing can be generated without paying from $29/mo; only the Contact Sales custom plan needs a conversation.](https://faceless.so/pricing)

### 2. Descript

Text-based AI video and audio editor with an agentic co-editor, API and MCP server.

**Where it improves on ImageToSTL:**
- [API access: partial — A documented REST API with tokens and webhooks exists but is presented as early access and is limited to paying users, so the Free plan cannot drive it.](https://www.descript.com/api)
- [Seat model: yes — Pricing is per person per month with a hard ceiling on self-serve tiers: one seat on Hobbyist, up to three on Creator, up to five on Business.](https://www.descript.com/pricing)
- [Single sign-on: partial — SAML SSO with SCIM provisioning against your own IdP is an Enterprise capability, absent from the Hobbyist, Creator and Business cards.](https://www.descript.com/enterprise)

**Trade-offs against ImageToSTL:**
- None found.

### 3. Runway

Credit-metered AI video, image and audio generation with an agent, API and MCP server.

**Where it improves on ImageToSTL:**
- [Model choice: yes — You can let Runway pick or name the model yourself, and the developer platform adds a router that chooses per request against your cost, quality and latency rules.](https://runway.com/product/agent)
- [API access: yes — Runway Dev is a self-serve usage-billed API covering every model, and the Team and Enterprise creative plans also carry API access against the shared credit pool.](https://dev.runwayml.com/)
- [Seat model: yes — Team is billed per seat monthly starting at two users with a nine-member ceiling on that plan; going beyond nine means an Enterprise conversation.](https://runway.com/pricing)

**Trade-offs against ImageToSTL:**
- None found.

### 4. Midjourney

Subscription text-to-image and image-to-video generation on the web and in Discord.

**Where it improves on ImageToSTL:**

**Trade-offs against ImageToSTL:**
- [Open models: no — All generation happens on Midjourney's own hosted models; the terms forbid reverse engineering the service and no open-weight model option exists on any tier.](https://docs.midjourney.com/hc/en-us/articles/32083055291277-Terms-of-Service)
- [Free tier: no — No standing free plan and no trial on the website or Discord; the only limited trial sits on the separate niji journey mobile app.](https://docs.midjourney.com/hc/en-us/articles/27870399340173-Free-Trials)
- [Opt out of training: no — Using the service grants a perpetual, irrevocable licence over prompts and assets and the privacy policy covers data collected while training its models; no opt-out is published.](https://docs.midjourney.com/hc/en-us/articles/32083055291277-Terms-of-Service)

### 5. HeyGen

AI avatar video platform for generating, editing and translating video from a script or a prompt.

**Where it improves on ImageToSTL:**
- [Runs autonomously: yes — Video Agent takes one prompt and completes scripting, avatar choice, scene composition and rendering without a human step, with a fire-and-forget mode alongside a multi-turn chat mode.](https://developers.heygen.com/mcp/overview)
- [API access: yes — A documented public REST API with key authentication drives video, avatar, voice, translation and template endpoints from your own stack.](https://developers.heygen.com/docs/quick-start)
- [Seat model: yes — Seats are priced per member per month on top of the Business plan fee; the plan itself is the floor and no published ceiling applies.](https://www.heygen.com/pricing)

**Trade-offs against ImageToSTL:**
- None found.
