Onboarding and enterprise rollout support
Facts, claims, scope, pricing, and proof points should stay traceable to uploaded source material so reviewers can inspect the draft before it reaches a client. In the response workspace, a deterministic response-quality pass flags unsupported claims, unsupported high-risk claims, placeholder text, duplicate answers, and word- or character-limit breaches so the team can resolve them first. When the buyer issues a structured questionnaire, Arc writes your reviewed responses back into the original XLSX, CSV, or DOCX file, deterministically and in place, preserving the workbook's formulas, styles, and layout as well as Word content controls and response-table cells. A preflight previews every target first and blocks on protected sheets, formula cells, merged cells, dropdown values the buyer does not allow, missing required or scored answers, and conflicting requirements, so a person still runs the final check and submits. Arc runs proposal review as governed team execution: each requirement can carry a response owner, a reviewer, a due date, and a workflow status, and subject-matter-expert, security, legal, commercial, and executive review gates track who must approve, their decision, and when. A deterministic workload view surfaces open, due-soon, overdue, and escalation tasks under a team capacity policy, with reviewer reminders. Your organization still owns every approval. Arc creates recipient-specific tracked view-only or view-and-download links. You can send the link directly by email from Gixo or copy it to send yourself, and receive alerts when buyers view, download, ask questions, or accept; Arc does not submit the proposal to a procurement portal. Arc includes native simple electronic signature: a frozen PDF snapshot, named signers on tokenized links, typed-name adoption, and a sealed PDF with an audit certificate. It is not a qualified or certificate-based digital signature. The paid plans below include proposal types, source upload, editing tools, and PDF, DOCX, and HTML export, plus Markdown, JSON, and plain text.
Product fit
Is Arc right for you?
Not the right fit when
You need a high-volume bid-operations platform with self-serve system synchronization, payment collection, a qualified or certificate-based signature, automatic submission to a procurement portal, or a prediction that a bid will succeed.
What to expect
The free analyzer is a deterministic review aid for structure, section coverage, and requirement-coverage signals. It does not certify RFP compliance or replace final human review.
What your team should review
The proposal owner still confirms every requirement, scope item, price, obligation, assumption, proof point, and client commitment before handoff.
Important limitation
Arc's deterministic analyzer reports structure and requirement-coverage signals; it does not certify RFP compliance or predict bid or sales outcomes.
Built to take a proposal from source files to review, delivery, and simple e-sign
Facts, claims, scope, pricing, and proof points should stay traceable to uploaded source material so reviewers can inspect the draft before it reaches a client. In the response workspace, a deterministic response-quality pass flags unsupported claims, unsupported high-risk claims, placeholder text, duplicate answers, and word- or character-limit breaches so the team can resolve them first.
Start with your files
Upload RFPs, statements of work, decks, emails, and reference files so the draft starts from real context.
Proposal-specific writing
Each proposal type follows its own structure and tone instead of using a generic writing prompt.
Questionnaire round-trip
When the buyer issues a structured questionnaire, Arc writes your reviewed responses back into the original XLSX, CSV, or DOCX file, deterministically and in place, preserving the workbook's formulas, styles, and layout as well as Word content controls and response-table cells. A preflight previews every target first and blocks on protected sheets, formula cells, merged cells, dropdown values the buyer does not allow, missing required or scored answers, and conflicting requirements, so a person still runs the final check and submits.
Review as team execution
Arc runs proposal review as governed team execution: each requirement can carry a response owner, a reviewer, a due date, and a workflow status, and subject-matter-expert, security, legal, commercial, and executive review gates track who must approve, their decision, and when. A deterministic workload view surfaces open, due-soon, overdue, and escalation tasks under a team capacity policy, with reviewer reminders. Your organization still owns every approval.
Tracked delivery links
Arc creates recipient-specific tracked view-only or view-and-download links. You can send the link directly by email from Gixo or copy it to send yourself, and receive alerts when buyers view, download, ask questions, or accept; Arc does not submit the proposal to a procurement portal.
Simple electronic signature
Arc includes native simple electronic signature: a frozen PDF snapshot, named signers on tokenized links, typed-name adoption, and a sealed PDF with an audit certificate. It is not a qualified or certificate-based digital signature.
More of the Arc response workspace: language, buyer replies, releases, and bid strategy
These run on the same proposal as the draft, so the source files, reviewed answers, and approvals stay in one record.
Proposals in the buyer's language
Arc writes a proposal in the language you pick on the create page rather than drafting in English and translating, and the buyer edition, Word, PDF, and PowerPoint files of an approved release are laid out in that language, right to left for Arabic and other right-to-left scripts. Reviewers still check terminology and figures in that language.
Buyer acceptance and questions
On a tracked link, the buyer can press Accept proposal and type a name, and the acceptance appears in your delivery history. When the link shares a reviewed proposal edition, the buyer can also record a question or next-action suggestion for your team without changing that edition. Acceptance is a recorded response, not a signature.
Package preflight and approved releases
A package preflight checks submission readiness, response quality, every buyer-questionnaire mapping, and required attachments before you submit. An approved release is created only when every answered active requirement is approved and each approved review gate still matches the current revision; it freezes a submission snapshot with a SHA-256 manifest of the buyer edition, DOCX, PDF, PowerPoint, and returned buyer files, plus handoff instruction packs for Business, Lumen, Lex, and Prism that still need review in each product.
Compliance matrix and response pack
From the response workspace you can export a compliance matrix as CSV, with requirement, source location, compliance, evidence, owner, reviewer, due date, response, and word or character limits, and a response pack as a PowerPoint deck of the answered requirements.
Revised RFPs and addenda
When the buyer issues a revised RFP or an addendum, Arc compares the requirements extracted from the earlier and the later source and lists each one as added, removed, or modified, so the team can see what changed before re-answering.
Approved answers and their recorded outcomes
Arc keeps an approved-answer library with review decisions and an audit export, and its projects view reports win rate, loss reasons, and reusable-answer effectiveness from outcomes your team records. The associations are descriptive, not causal, and never approve or publish content.
Bid qualification, stakeholders, and competitors
Before drafting, a team can score bid qualification against weighted criteria and a decision threshold, map buyer stakeholders by role, influence, and stance, and keep competitor profiles and differentiators linked to evidence alongside the team's win themes. The bid decision stays with your team.
How It Works: AI proposal software after the first draft
The flow is source to review: pick the proposal type, add your files, then keep questionnaire, gates, delivery, and simple e-sign on the same proposal.
1
Choose from 21 proposal types
Sales, consulting, RFP response, grant, government, renewal, partnership, quote, internal business case, and more.
2
Upload source files
Gixo reads multiple files and distributes context across sections.
3
Get a structured draft
Each proposal is built with sections based on the proposal type, not a generic outline.
4
Fill the buyer questionnaire in place
When the buyer issues a structured questionnaire, Arc writes your reviewed responses back into the original XLSX, CSV, or DOCX file, deterministically and in place, preserving the workbook's formulas, styles, and layout as well as Word content controls and response-table cells. A preflight previews every target first and blocks on protected sheets, formula cells, merged cells, dropdown values the buyer does not allow, missing required or scored answers, and conflicting requirements, so a person still runs the final check and submits.
5
Run review gates and quality checks
Arc runs proposal review as governed team execution: each requirement can carry a response owner, a reviewer, a due date, and a workflow status, and subject-matter-expert, security, legal, commercial, and executive review gates track who must approve, their decision, and when. A deterministic workload view surfaces open, due-soon, overdue, and escalation tasks under a team capacity policy, with reviewer reminders. Your organization still owns every approval.
6
Deliver, sign simply, and export
Arc creates recipient-specific tracked view-only or view-and-download links. You can send the link directly by email from Gixo or copy it to send yourself, and receive alerts when buyers view, download, ask questions, or accept; Arc does not submit the proposal to a procurement portal. Arc includes native simple electronic signature: a frozen PDF snapshot, named signers on tokenized links, typed-name adoption, and a sealed PDF with an audit certificate. It is not a qualified or certificate-based digital signature. Export as PDF, DOCX, HTML, Markdown, JSON, or plain text.
