Tender review with sources: how the workflow works
Short answer
A tender document can contain an instruction aimed at the model that reads it. A document reader with no network and no tools passes on only a closed set of fields, so a foreign instruction never reaches the part that plans actions. At Syntalith an agent costs from €3,000 net, and with 300 tender notices a month at 10 minutes each it pays back in 2.3 months.

According to the Syntalith demonstrator (2026), a historical test of the tender document reader's security boundary used 14 controlled artefacts with hostile instructions, and the snapshot of notices holds 67 records.

There is a notice. Is there material for a decision
An analyst collects notices from several registers. The description of a procedure is not enough for a decision: you need the source, the deadline and a note of which documents are still missing. In our demonstrator the view orders 67 saved records from BZP, the Polish public procurement bulletin, and TED, the EU's tender journal, from a controlled snapshot. It lets you narrow the register and the region and go to the original notice. A missing tender specification (SWZ) stays visible instead of vanishing under a summary.
The document reader and the planning part have different permissions. The reader has none of the planner's tools and no access to its database, and passes on a closed data contract. That limits the path by which unverified content can reach the next stage. OWASP describes prompt injection as the first risk on its list for applications built on language models.

- 03Quarantinesuspicious content flagged and stopped

- 14 controlled artefacts with hostile instructions, from outside these tenders
- Keeping 670 fields intact measures data transport, and reading quality needs its own measurement
- No evidence of market completeness or of the quality of bid decisions
What a protected tender agent costs and when it pays back
- Today
- 300 notices × 10 min = 50 h × €34.90 = €1,745
- With the system, a person checks the output in 25% of the time
- €436
- Model, 2 calls per case, Claude Sonnet 5.5
- €9
- Cost of one case
- €5.82 today, €1.48 with the system
- Saving
- €1,300 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: 6,000 input tokens and 500 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 it on. What stays is the time to check the output, 25% of today's work in the scenario. Before we quote, we measure both times on 20 to 100 cases your team has already handled, in a €0 test that takes 5 working days.
According to the Polish Public Procurement Office (2026), 53.6% of Polish tenders above the EU thresholds received only one bid. Reaching the right notices faster has value, but only when the analyst trusts the fields they read.
Reader security and the quality of tender monitoring
Testing the security boundary and the quality of market monitoring are two separate tasks. Controlled trials do not prove that all notices were collected, and keeping fields intact does not say whether the company should bid. So the first business scope sets the sources and categories the team really follows, and the deadline is always checked at the source. Anthropic, in Building effective agents, advises adding complexity only when a simpler solution is not enough. A reader with no tools is such a simpler solution.
A few registers, a manual review is enough
register alerts and a list of followed categories
no build
Many notices, document analysis
monitoring with an isolated reader and a closed set of fields
from €3,000
A bid decision against the company's criteria
an agent that prepares an assessment for the analyst
priced after the review
Where to start
First we compare the notices found with manual monitoring and keep source completeness apart from the assessment of fit. To prepare: a profile of the procedures you look for, the registers and the owner of the bid decision. The current process is described in tender monitoring with AI. We build this kind of rollout as part of AI agents. For the free process review, a description of one case from recent weeks and the tools it went through is enough. You do not need to send confidential documents, and you get a written plan within 2 working days.

How we count the payback: tender monitoring
We run the same count for your tenders in the free process review.
€1,047
a month for reviewing 600 tender notices by hand
Payback: 3.4 mo.
3 minutes to review a notice 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: Claude Sonnet 5.5, about 6,000 + 800 tokens per notice with its assessment, at the ECB rate of 1.1205 USD per euro on 22 October 2026. Reading a notice in our system alone costs about €0.0002. The tender margin is a scenario: we assume that 1 in 5,000 notices spotted in time ends in a winning bid with a margin of €4,590. In the review we count it on your tenders.
