Responsive, Loopio and AutogenAI help you draft from approved content. So does Prysme. Then it puts the finished draft in front of a panel of AI evaluators, who score it against the call's own criteria the way the buyer or funder will.
The free trial lasts 14 days, with no credit card required.
Your team reviews each section. Before the proposal goes out, a panel of AI evaluators reads the whole draft the way the buyer or funder will. Each one scores it against the call's own evaluation criteria and weights, as Prysme read them from the call, and against their profile's criteria.
The profiles include a buyer's IT director, a buyer's CFO, an information security assessor, a public procurement evaluator, an EU grant evaluator and a community foundation program officer. The Business edition offers 23 of them and the Nonprofit edition 22. In a proposal, Prysme offers the profiles that fit its type: buyer readers for RFPs and questionnaires, funder readers for grants and reports. An evaluator can also be built from the call in one click: the call's scoring grid and its weights become the evaluator's criteria.
Each reviewer scores every criterion, gives a verdict, lists strengths and weaknesses, ranks the fixes by priority and asks the questions you are likely to face. Each fix quotes the relevant passage and names its section. Every reviewer also runs four checks: figures with no visible source, win themes not tied to a scoring criterion, results that restate the activities, and a budget narrative that differs from the budget table or the work plan.
Your team selects the fixes it accepts, and Prysme redrafts the affected sections from your own sources. When a fix needs a figure your sources do not contain, Prysme asks you for it. A section edited by hand is redrafted with your agreement. A second run of the panel shows the new scores.
Prysme reads the scoring grid in the call, builds a reviewer from it and scores the draft against each criterion. The recording has no sound and includes captions.
The organization, call and figures in this sample are fictional.
