AI agents for following up on document review comments
Short answer
An AI agent links a client's comment on documentation with the revised version of the file and the author's reply, and prepares a specific request for a fresh review for the project manager. A closed upload task does not replace the reviewer's answer. The agent costs from €3,000 net at Syntalith and, with 120 documentation comments a month at 25 minutes each, pays back in 2.3 months.

The revised manual is waiting to be read
During a review of an operating manual, the client asked for a chapter on returns. The author put the revised file in the folder, noted on the task that the chapter had been added and marked the task as done. The project manager still needs the client's answer on this version. The agent gathers the comment from the correspondence, the author's reply and a link to the revised file, and prepares a draft:
In response to the comment about the missing description of returns, the author sent a revised manual and said this chapter has been added. Please review this version and tell us whether the description meets your comment or needs further changes.
The manager checks the draft and attaches the file. The recipient gets a specific passage to assess and the reason for coming back to the manual.

What it costs and when it pays back
- Today
- 120 documentation comments × 25 min = 50 h (€1,745)
- With the system, a person checks the output in 25% of the time
- €436
- Model, 3 calls per case, Claude Sonnet 5.5
- €5
- Cost of one case
- €14.54 today, €3.68 with the system
- Saving
- €1,304 a month
Payback of €3,000
2.3 months
The volume, the time and the checking share are the scenario's assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat. Model: 5,000 input and 600 output tokens per call at Anthropic's rates, converted at the ECB rate of 1.1205 USD per euro on 22 October 2026.
The count covers the work around a case: searching, reading, writing and passing things on. What remains is the time to check the output, 25% of today's work in the scenario. Before the quote we measure both times on 20 to 100 cases the team has already handled, in a €0 test that takes 5 working days.
The easiest thing to lose is the link between an answer and a file: an „all good” email may concern the previous version or another passage. A new manager taking over the project sees at once which comments need action and to whom they were passed.
When an approval task is enough
If the comments, the revised file and the client's answer fit in one tool, use its approval workflow: Asana describes approval tasks, where the reviewer approves, asks for changes or rejects. Assigning a task to a reviewer does not, however, limit completing it to that person. The agent is more useful when the manager rebuilds the links between emails, tasks and folders. The article on acceptance certificate workflows covers passing a signed certificate on to billing.

Where to start
The first project covers one type of documentation. On a finished case, the manager judges whether the prepared material would have let them go straight to the right reviewer. AI for managers and boards describes the decision package. We build this as part of AI agents. For the free process review, a description of one case from recent weeks and the tools it ran through is enough. You do not need to send confidential documents, and you get a written plan within 2 working days.

€1,675
a month for preparing 12 management reports
Payback: 2.1 mo.
4 hours to prepare a management report and checking in 15% of the old time are our assumptions. €34.90 an hour is the EU average hourly labour cost for 2025 according to Eurostat, for companies with 10 or more employees. Model cost: checking the commentary in our reporting system (about €0.0002) plus compiling the data (Claude Sonnet 5.5, about 30,000 + 2,000 tokens), at the ECB rate of 1.1205 USD per euro on 22 October 2026.
