What AI does well
First drafts from source code. Claude and ChatGPT read a function, a class, or an endpoint definition and produce a usable draft of the reference entry in seconds. Mintlify goes further: it watches your repo and opens a pull request when an endpoint changes, so the docs drift less. The gain is real, often two to three hours saved per API section. The caveat: the draft is a starting point, not a finished entry.
Style and tone passes. Jasper and Claude both apply a house style guide well once you give them a real one, not a vague one-liner. I fed Claude a 12-rule style guide for a client’s docs and it held to it across 40 pages without drifting. This saves a full editing pass on voice and tense.
Rewriting for a new audience. Turning an engineer-facing changelog into a customer-facing release note is a task ChatGPT and Claude both do well. You get a readable first pass in one prompt. You still need to check every claim against the actual change.
Boilerplate sections. Prerequisites, installation steps, error code tables: AI generates these fast from a template plus your product’s real values. This is the least risky use case because the structure is fixed and the model has less room to invent.
Where it fails
Invented API details. I asked Claude to document a REST endpoint from a partial OpenAPI spec. It filled the gaps with plausible-sounding fields that were not in the spec and not in the actual API. A reader who trusted the doc would have shipped broken integration code. This is the single biggest risk for technical writers using AI on reference material.
Version drift. Ask ChatGPT about a library’s current syntax and you often get an answer that matches an older major version. For fast-moving SDKs, this shows up weekly. Jasper has the same problem because it has no live connection to your codebase.
Losing the thread across a long doc set. None of these tools reliably remembers a decision you made in section 2 by the time you reach section 9 of the same guide. You end up re-pasting context, which defeats the point of a long editing session. This overlaps with the general context problem described in context engineering.
My take
My take (August 2026, Bernat Sampera)
I use AI for every first draft now, but I do not publish a line I have not checked against the source. The verdict holds: roughly half the drafting time disappears, and none of the fact-checking time does. Mintlify’s repo-aware drafting is the closest thing to a real workflow fit, because it ties the draft to the actual code instead of the model’s memory. Claude holds a style guide better than ChatGPT or Jasper in my tests, which matters more than raw fluency for docs work. If you write API reference material, treat every generated parameter, flag, or default value as unverified until you have opened the source and confirmed it. If you write conceptual or onboarding content, the risk is lower and the tools already pay for themselves. See Jasper vs Claude for how the two compare on tone control specifically.
What I would build
The unsolved problem is a documentation assistant that keeps a live, structured map of your product: every endpoint, parameter, and UI label, tied to its source of truth, refreshed on every code change. Today’s tools either read a snapshot once (a stale draft) or reconnect to the repo but forget every editorial decision you made last week (a fresh but context-blind draft). A real solution would hold both at once: the current state of the product and the accumulated style and accuracy decisions from every prior doc, so a writer never has to re-explain a rule or re-verify a fact the tool already confirmed last month.
Verdict (August 2026, Bernat Sampera): AI cuts first-draft time on reference docs and how-to guides by roughly half, but it still invents parameters, flags, and API fields that do not exist in your codebase. Overall: 3.6/5.
