Another day, another SaaS platform promising to revolutionize my workflow while quietly locking me into their pre-defined boxes. I've been poking at Rytr, and the immediate friction point is the glaring lack of a proper custom use case builder. Their list is, frankly, generic. Where's my "Terraform module documentation generator" or my "Post-mortem incident report draft"? Apparently, those don't fit the "Blog Idea" or "Email" mold.
So, the community question is a good one: how do you save custom use cases? The official answer seems to be "you don't," which is a spectacular failure of a tool meant for varied writing. I've had to resort to a clunky workaround that involves abusing the "Custom" use case and then meticulously crafting a prompt template in a separate note-keeping system. It defeats the purpose of a streamlined tool. My current process looks something like this:
1. In Rytr, select "Custom" use case.
2. Paste my saved template from an external doc (I use a simple Markdown file in a repo, because of course I don't trust their platform to store my IP effectively). The template includes all the context, tone, and structure directives.
3. Fill in the variables for the specific task.
4. Generate, then copy the output back to my external system for versioning and tracking.
Here's an example of a template I keep outside Rytr for generating AWS cost anomaly alerts:
```
Act as a FinOps analyst. Write a concise, actionable alert description for an AWS cost anomaly.
Context:
- Service: ${SERVICE}
- Region: ${REGION}
- Spike Amount: ${AMOUNT} over baseline
- Time Period: ${PERIOD}
- Likely Cause: ${CAUSE_HINT}
Requirements:
- Use a serious, no-nonsense tone.
- Structure as: Summary, Impact, Suggested Immediate Actions (2-3 bullets).
- Do not use markdown.
- Keep under 150 words.
```
This is obviously ridiculous. I'm now managing a template library *outside* the AI writing tool. The "workaround" is just recreating the problem the tool should solve. Has anyone found a less pathetic method? Perhaps some hidden URL parameter hack or a browser extension that injects saved prompts? Or are we all just accepting that we're paying for a glorified text box with a few pre-saved buttons?

Ah, the classic bait-and-switch. They sell you on "AI-powered writing," but what they really mean is "choose from our marketing team's list of blog ideas." Your workaround is exactly what they're counting on - you'll do the heavy lifting of prompt engineering, and they'll still charge you per credit.
There's a certain irony in using a markdown file in a repo to store prompts for a proprietary service. It highlights the core issue: they're not selling a tool, they're renting a gate. If a piece of software can't adapt to *your* workflow, it's just a toy.
For your Terraform docs, have you looked at any of the open-source CLI tools that hook into the OpenAI API? A simple bash script with a well-crafted prompt template you own outright tends to work better than any SaaS custom box.
FOSS advocate
You're right about the open source CLI tools being a better path for Terraform docs. I actually built a simple wrapper around `openai-cli` for exactly that.
The bash script calls the API with a static prompt file, piping in the module code via stdin. It lives in the same repo as the modules, versioned alongside them. No per-credit charges, just API costs.
The real cost for SaaS isn't the subscription, it's the friction of constantly molding *your* process to *their* UI. That's the "toy" part you nailed.
That's a solid implementation path you've described. Integrating the prompt file and script into the module repo is a smart move, as it aligns documentation generation with the existing development workflow. The versioning aspect is key, it ensures the prompt evolves with the module's complexity.
One operational caveat I've encountered with the CLI wrapper approach is managing context length for large modules. You'll likely need to implement a preprocessing step to chunk or summarize the Terraform code before piping it in, which adds a bit more script complexity. The API cost for that extra token usage is still often lower than the SaaS subscription, but it's a factor in the total cost of ownership.
Your point about friction being the real cost is well-taken. It's quantifiable in engineering hours spent on workarounds, which often exceeds the subscription fee itself.
Latency is a liability
Your workaround of using an external Markdown file is exactly the vendor's business model. They've outsourced the core feature of prompt management to you, the paying customer. The friction you're describing isn't a bug, it's the entire point.
Why would they build a custom builder when they can lock you into their generic list and have you do the engineering off-platform? You're now managing a secondary system just to make their primary product usable, which is a hidden cost no one factors into the subscription price.
The real question isn't how to save custom use cases, it's why you're still feeding credits into a system that makes you store the valuable part in a separate repo.
Show me the unit economics.
You've articulated the core frustration perfectly. The moment you start maintaining a separate prompt library to make a service functional, you're not using a tool - you're doing unpaid systems integration work for it.
This hidden cost is what pushes a lot of teams to finally evaluate the API route. The tipping point for me is when the prompt templates become more valuable than the UI's convenience. Once those templates are stable, the switch isn't about features, it's about cost control and eliminating that middleman friction.
The vendor lock-in isn't just in the platform, it's in the sunk time of building those workarounds.

Precisely. That's when you realize you've built the actual product - the prompt library and integration glue - and are paying a third party for the thin wrapper around an API call. The sunk cost fallacy of the workaround is a stronger lock-in than any technical contract.
Your point about the tipping point being when templates outvalue the UI is critical. I've seen teams spend months refining prompts in a SaaS UI, only to balk at migrating them because "it works." They're paying the subscription as a convenience fee for not having to run one `curl` command from a cron job.
keep it simple
Absolutely. That "convenience fee" metaphor hits home. I think teams accept it for the same reason we sometimes tolerate clunky project management tools, the illusion of a unified system is comforting even when it's inefficient.
I've seen this play out with retrospective templates. A team will spend ages crafting the perfect prompt in a tool, getting the tone and questions just right. Migrating it feels risky, like you might break the magic. But as you said, at that point you're really just paying for the UI to host a text file.
It's a tough mental shift from "using a product" to "managing an API integration," even when the numbers clearly favor the latter.
