Bidwin gives bid writers and managers a custom drafting system, built around their own bid/tender documents, evidence files, and writing style — not generic AI.
Too much documentation
Every bid/tender adds piles of schedules, policies, and scoring criteria before a word is even written.
Judgement still matters
Generic AI drafts quickly, but doesn't protect your data or IP, and can produce slop, hallucinate or invent evidence, overclaim and miss scoring criteria.
Competitors already using AI
The question is no longer "should we use AI?" The risk is falling behind rival teams that already do.
Not generic AI. Not another SaaS platform. A custom drafting system inside your own Claude account.
Upload the tender pack
Instructions, schedules, question sets, scoring criteria.
Add your evidence
Reports, case studies, accreditations, endorsements, awards, policies, method statements.
Show it what good looks like
Winning samples, house style, tone preferences.
Get structured first drafts
Section by section, evidence-cited, compliance-mapped.
Bidwin works exclusively from your own, supplied information. It flags and integrates your key evidence (instead of inventing it), and applies the bid/tender's scoring criteria.
Save time
Days of document processing to structured first drafts, faster.
Keep control
Works from your material. Flags gaps instead of inventing answers.
Improve consistency
Your examples, tone, and structure — responses sound like your organisation.
No new platform
Works inside your own Claude Pro account — no migration, no new logins.
