Pre-scan every donor appeal, grant proposal, annual report, and impact story before it leaves the development office. Sentence-level highlights show exactly which lines read AI on mission-driven prose, so the tone the donor or programme officer reads is the tone you intended. Calibrated for long-form fundraising and reporting narrative. Team workspaces on Business for development offices and NGO comms teams. GDPR aware, no training on submitted drafts. Free to try. No card.
Most nonprofits run under 20 people. A single staff communications lead may ship a year-end appeal, a quarterly newsletter, weekly social posts, three grant proposals, and an annual report inside a quarter, often alongside programme duties. Development directors, grants writers, donor communications leads, and programme staff each touch parts of the same narratives. TextSight is the pre-send scan step that keeps the volume from collapsing the trust.
The nonprofit content stack runs from the concept memo to the close-out report. Pre-scanning fits every stage because programme officers and major donors now read with AI in mind, and several major funders have added human authorship attestation language to submission policy as of 2025.
Grant proposals, letters of inquiry, foundation reports, major-gift cultivation notes, and stewardship letters all carry distinct authenticity stakes. A flat opening on a $50K cultivation note reads as routine, and that perception costs renewals. Pro at $19.99 a month, or $14.99 a month on yearly, gives a solo development writer 10,000 character pastes and unlimited scans for the iteration weeks. Business at $39.99 a month, or $29.99 a month on yearly, fits the development office with 5 seats and shared scan history.
The comms lead ships volume across surfaces every week. Year-end appeals carry the heaviest revenue load on the calendar. Annual report narratives set stakeholder credibility for the year. Quarterly newsletters and social posts compound over months into the organisation's brand voice. Pre-scanning every appeal and report section catches the AI flavour before it touches the donor inbox.
Impact stories and beneficiary narratives are the single highest-trust pieces of content on a nonprofit site. Programme staff usually draft these from intake notes and field reports. Board reports go to a small audience but carry outsized influence on strategy. Each section round-trips the same scan workflow as a grant narrative.
Federal agencies and major foundations updated submission policy through 2025 to require human authorship attestation or AI disclosure on the cover form. Programme officers read narratives with AI in mind regardless of policy text. Pre-scanning is the defensible posture in 2026.
NIH updated policy in 2025 to require human authorship attestation on submitted research narratives. NSF emphasises intellectual merit and broader impacts as dual review criteria, and broader impacts in particular attracts AI-templated phrasing because the section invites general claims about educational outcomes and underrepresented populations. Reviewers know the standard tropes and flag them quickly.
Wellcome Trust requires AI disclosure on the cover form for major research programmes. MacArthur asks applicants to attest to authorship on the application portal. Both review panels include AI-shaped prose in their evaluation notes regardless of whether the formal policy text mentions it. Pre-scan, rewrite reds, then disclose honestly.
Ford, Open Philanthropy, and the Gates Foundation added AI disclosure questions to their application portals during 2024 and 2025. Community foundations and smaller family foundations are following at varying speeds. Treat every funder as if AI disclosure matters, and let the scan history be the evidence trail that supports the disclosure.
A programme officer opens a stack of letters of inquiry on a Monday morning. Forty letters in the pile, all from organisations asking for $25K to $250K, all describing a population in need, a theory of change, and a leadership team committed to impact. By letter twelve she has a working pattern for what generic looks like. The applications that survive the first cut are the ones that name a specific person, a specific intervention, and a specific number that does not appear in any other letter she will read that quarter.
Pro at $19.99 a month standard, $14.99 a month on yearly billing, fits solo development writers and consultants. Business at $39.99 a month, or $29.99 a month on yearly, fits nonprofit comms teams and development offices with 5 seats.

Each genre has its own authenticity stakes and its own scan threshold. The Authenticity Score floor differs between a $50K cultivation note and a federal grant methodology section. Calibrate the threshold to the genre, not the page count.
Programme officers pattern-match boilerplate within the first paragraph. Scan letters of inquiry, full proposals, and every narrative section: need statement, theory of change, methodology, evaluation, sustainability, broader impacts. Aim for the 55 to 70 band on methodology and theory of change, and 75 plus on need statement and impact. Pro caps each scan at 10,000 characters, which fits a typical narrative subsection.
Year-end and giving-day appeals carry the heaviest revenue load on the calendar. A flat opening or a generic ask paragraph costs gifts directly. Scan the appeal, target an Authenticity Score above 80, rewrite the flagged passages in the organisation's voice before send. The first appeal that lands because the tone is right covers a Pro seat for a year.
Major-gift cultivation notes, giving-day campaigns, monthly-donor programmes, and capital-campaign collateral each carry their own voice. A generic note to a $50K donor reads as routine, and that perception costs renewals. Pre-scan campaign copy across the cycle and treat the score as a quality gate before send.
The executive director letter, programme highlights, and impact sections set stakeholder credibility for the year. Board members, major donors, and partners read these closely. Impact stories and beneficiary narratives carry the heaviest authenticity load on a nonprofit site: donors come back for the named person, the specific moment, the texture of the change. Aim 75 plus on impact stories and rewrite reds rather than humanising.
Board reports go to a small audience but carry outsized influence on strategy. Stewardship letters to major donors, foundation interim reports, and year-end programme updates run the same scan workflow. Pro 90-day history keeps every report scan retrievable across the cycle, useful when a programme officer references an interim report in a renewal conversation.
Mission language is the AI tell. The phrases nonprofits have leaned on for decades, the mission-mission-mission cadence, the inflated impact verbs, and the abstract theory of change paragraph, are exactly the patterns current AI tools produce when asked to draft a nonprofit document. AI-drafted nonprofit copy sits inside the existing genre conventions, which means it does not stand out as obviously AI to anyone except the people who read this writing for a living.
Donor list churn accelerates when the appeals start reading as composed rather than reported. Open rates drop quarter over quarter, click rates drop faster, and major-donor renewals follow. The donors who unsubscribed cannot tell you the precise moment they stopped trusting the voice; the pattern just stopped feeling like the organisation they fell for. Pre-scanning every donor email catches the AI flavour at draft stage.
Impact stories are the single highest-trust pieces of content on a nonprofit site. Donors come back for these. AI-drafted versions smooth specifics into a generic arc that hits the structural beats without the texture. The fix is not to stop using AI for outlining; it is to draft from interview notes or programme reports in the organisation's voice, then scan, then rewrite the flagged passages with the specifics intact. Target an Authenticity Score above 80 on a beneficiary story.
The story opens with a generic hook about resilience or hope. The middle paragraph summarises the programme rather than the person. The closing paragraph thanks supporters in language that could be lifted onto any other organisation's site. Each of these failure modes flags at the sentence level on a scan, which lets the editor rewrite the specific lines rather than restart the piece.
Consent, dignity, anonymisation, and editorial accuracy are decisions only the programme team can make. The detector is downstream of those decisions. It does not replace the policy work; it tells you whether the final draft you are about to publish carries the tone of the person you interviewed.
The default AI voice for a nonprofit document is corporate, polished, and emotionally flat. The organisation you actually run is warm, specific, urgent, and grounded in a particular community. The pre-scan is what keeps the draft you ship sounding like the second one and not the first.
Warmth in nonprofit prose comes from concrete detail, named people, and lived consequence. AI defaults to abstract warmth: hope, resilience, transformation, community. Both registers can clear a score in isolation, but the abstract register reads as templated when stacked across a multi-section narrative. Pre-scanning the full document together catches the slide.
Year-end appeals and crisis campaigns lean on urgency by design. AI-drafted urgency reads as inflated: catastrophic, unprecedented, life-changing, critical. Specific urgency reads as real: by Friday, before the school year starts, before the eviction notice clears. The sentence map surfaces the inflated lines and lets you swap them for the specific ones.
Nonprofit narratives often ship from three to five contributors: development director, grants writer, programme staff for impact sections, finance for budget narrative, sometimes a contracted writer. Each voice is different and each enters AI assistance differently. Business tier with shared scan history lets the team see the same Authenticity Score and flagged sentences across the consolidated draft, so the threshold is a team agreement rather than a per-author judgment.
Social posts and email cadence compound over months. AI-drafted social copy is the easiest way to drift into generic nonprofit voice without anyone noticing the slide. Scan a representative sample weekly and adjust the prompts you are giving the tools. The brand voice your major donors notice is the cumulative one, not the headline campaign.
A typical development office runs three to five people across grants, donor communications, and major gifts. The communications team adds one or two more for newsletter, social, and design. Programme staff contribute impact stories on top of programme duties. Business tier with 5 seats and shared scan history lets the team agree the threshold and edit against the same evidence.
The director of development creates the workspace and invites the grants writer, the donor communications lead, and any contract writers under a single Business plan. Each seat has its own login and scan history. The director sees activity across the team without reading every draft.
Each scan logs the writer, the deliverable, the Authenticity Score, the highlighted sentences, and the timestamp. During grant season, the director pulls a per-writer view to see which narratives still need work without opening every document. The shared history is the team-wide working memory across a 6-week proposal cycle.
Many nonprofits bring in contract grants writers during cycle peaks. A contract seat under the workspace gives them scan access for the duration of the engagement and gets removed when the contract closes, which keeps post-engagement data risk contained. Business tier audit log records who scanned what and when, useful when a subcontractor delivers a section that flags higher than the rest of the narrative.
Staff and contract writers know scans are part of the workflow, which shifts behaviour upstream into drafting. The director stops reading every appeal line by line and starts reviewing the score plus the highlighted sentences before approval, which is faster and more consistent. The shared bar is the team threshold, not a per-author judgment.
Grant narratives, donor lists, and impact stories are unpublished organisational work. They are also covered by GDPR in the EU and UK and by local equivalents elsewhere. TextSight is designed to honour those rules out of the box, not as a paid setting you have to find. A standard DPA is available on Business and Enterprise tiers for institutional procurement.
Grant narratives, donor emails, appeals, impact stories, and budget narrative submitted for scanning are never used to train the classifier or any other model. This is a contract clause, not a configuration toggle. It applies on the free tier the same way it applies on Pro and Business.
The free tier needs no email, no account, no identity. For development writers working on confidential applications or pre-disclosure funder strategies, this matters. You can scan a draft section without TextSight ever knowing who you are or which nonprofit you write for.
Scan history is private to your account. We do not share scan data with funders, programme officers, the board, partner nonprofits, or any third party. Your scans are not part of any external record.
Any scan can be deleted from your history. On Pro you can delete individual records. Data retention is bound to your settings, and a standard DPA is available on Business and Enterprise tiers for nonprofit comms teams that need one for institutional procurement.
