Pre-scan shareholder letters, 10-K and 10-Q drafting support, equity research, fixed-income commentary, M&A memos, fund prospectuses, and fintech blog posts before they reach the disclosure committee, compliance principal, or LP base. Sentence-level highlights flag the passages where conviction language goes flat and stock phrasing creeps in, so you can rewrite specific lines instead of arguing about a headline score. An adjunct to professional judgment, not a substitute for it. Free to try. No card.
Finance writing sits inside a regulated workflow and a reader base that prices conviction. Investor relations leads, sell-side and buy-side analysts, asset-manager communications teams, fintech editorial teams, and financial journalists all share the same need: a fast pre-review scan that surfaces AI residue before a disclosure committee, compliance principal, or institutional reader does.
The 2025 surveys of buy-side and sell-side desks both put generative AI in the drafting workflow at the majority of firms. Bloomberg's own coverage of analyst workflow shifts noted that AI-assisted research routinely passes initial editorial review and stalls only at compliance, when conviction language reads flat against the analyst's prior notes.
IR leads at public companies own the shareholder letter, the 10-K and 10-Q narrative drafting cycle, and the script for the earnings call. AI assistance shows up in the MD&A backbone, the segment commentary, and the boilerplate around forward-looking statements. The risk is a letter that reads as outsourced to a language model and erodes the institutional-investor trust that took years to build. Pro at $14.99 a month on yearly fits a solo IR writer; Business at $29.99 fits an IR team coordinating across the disclosure committee.
Analysts producing initiation reports, quarterly previews, post-print reactions, and thematic notes are the highest-conviction writing category in finance. The analyst is the product. AI residue slips in on the company-background and end-market overview sections and bleeds into the thesis paragraphs, where conviction has to live. Pro covers a solo analyst at five to fifteen notes a week; Business fits a research desk running team coverage with shared retention and an audit log.
Long-only managers, hedge funds, private credit firms, and multi-manager platforms write LP letters, quarterly updates, fund-launch decks, prospectus narrative, and one-off allocator notes. The stakes are the next fundraise. A letter that breaks the GP's established voice raises a question the LP did not have before, and a question is friction the relationship did not need.
Fintech blogs, neobank explainers, brokerage and robo-advisor education content, and independent financial newsletters compete on voice in a feed saturated with AI drafts. Financial journalists at newsroom outlets and on Substack also operate under stylebook rules that increasingly treat AI residue as an editorial signal. The piece that gets read twice is the one that still reads as a specific writer.
An equity research initiation note and a fintech blog post are not the same animal. Each finance genre has its own register, its own paraphrase density, and its own false-positive risk. Read the score in context of the document rather than chasing a single number across every kind of finance writing.
Annual and quarterly shareholder letters live or die on CEO and CFO voice. Healthy scores run 75 to 90 on letters drafted from a real strategy outline. The forward-looking-statements boilerplate and the standard performance recap are the highest-risk paragraphs because both default to stock phrasing under deadline. Scan the full letter, then re-scan the strategy section alone if the headline number is borderline.
SEC filings are not the place to chase an authenticity score; defined terms, risk factors, and segment language follow disclosure templates by design. Use the scan on the MD&A narrative and the segment-commentary drafts, where AI-assisted prose tends to flatten the operating context. Filed text always goes through counsel and the disclosure committee, not the detector.
Initiations, quarterly previews, post-print reactions, and thematic notes share a recognisable structure (thesis, drivers, valuation, key risks, recommendation). The structure alone usually does not push a human-written note over a flag threshold. Healthy scores run 70 to 88. The diagnostic is whether the thesis paragraphs carry analyst-specific texture; if they read like end-market generalities, the score will drop and the desk will quietly stop reading.
Sector outlooks, rates commentary, sovereign credit notes, and CLO and structured-credit memos use defined terminology and named curves heavily. The structure scans clean. The flag points are usually the macro framing paragraphs and the relative-value comparisons, where AI assistance produces smooth prose with the wrong direction or the wrong basis-point delta. Verify the numbers against your screens regardless of the score.
Pitchbook narrative, fairness-opinion supporting memos, and post-announcement commentary read template-heavy by convention. Healthy scores run 65 to 80. The defensive move is to weave specific synergy assumptions, named comparable transactions, and a clear premium framework into the prose so the document does not flatten into generic deal language.
Prospectus narrative, strategy descriptions, and fact-sheet copy follow filing conventions and named-vehicle language. Treat the scan as advisory on these documents and let the regulated content stay where the counsel and compliance team put it. Use the scan more aggressively on the marketing brochure and the LP-letter strategy commentary that sits alongside the regulated document.
Neobank explainers, brokerage education content, robo-advisor blog posts, and personal-finance editorial compete on accessible language calibrated against authoritative finance substance. Healthy scores run 75 to 90 when a specific writer is behind the piece. The risk is a generic post that reads as commodity content, gains no subscribers, and quietly damages the brand's editorial credibility over time.
Pro at $19.99 a month standard, $14.99 a month on yearly, is the right fit for a solo sell-side or buy-side analyst, IR writer, or fintech editor. Business at $39.99 a month standard, $29.99 a month on yearly, fits IR teams, research desks, and fintech editorial teams running shared review pipelines. Full details on the pricing page.

Finance writing operates inside named regimes. None currently mandates a blanket AI-use disclosure, but all of them require the substance of the communication to be accurate, substantiated, and fair regardless of how the draft was assembled. TextSight is an adjunct to professional judgment; this section is general context, not legal advice.
In the United States, the SEC marketing rule (Rule 206(4)-1 under the Investment Advisers Act) governs how registered investment advisers present performance, testimonials, and other communications with prospects and clients. It requires fair and balanced presentation, prohibits material misstatements, and sets substantiation standards. Regulation FD separately governs how public companies handle material non-public information; an IR draft that contains MNPI is not safe to paste into any third-party tool until a sanitised version is prepared.
FINRA Rule 2210 covers communications with the public for broker-dealers in parallel territory to the marketing rule. Retail communications, correspondence, and institutional communications each carry their own approval and review obligations. AI-assisted research that reads smoothly but carries unsubstantiated claims is a Rule 2210 problem whether or not AI use is disclosed.
In the European Union, MiFID II sets investor-information obligations on suitability, appropriateness, and the fair, clear, and not misleading standard for any communication with retail or professional clients. In the United Kingdom, the FCA financial promotion regime under FSMA, the FCA Handbook (COBS 4 in particular), and the consumer duty set comparable expectations. Across both regimes, substantiation, balance, and clarity on risk remain the core requirements.
Regulator positions are evolving. Some firms voluntarily disclose AI assistance in marketing footnotes, some restrict AI in client-facing copy entirely, and some treat AI use as a documented internal-policy matter without external disclosure. Confirm your firm's policy with compliance before relying on any general rule, and treat the TextSight scan as internal pre-review hygiene rather than a disclosure document.
Institutional investors read for conviction and continuity. A shareholder letter that breaks the established CEO and CFO voice raises a question on the buy side that the prior letter did not have, and a question is friction the relationship did not need.
Buy-side analysts at long-only funds, multi-strategy hedge funds, and pension allocators build a model of management voice across many quarters of letters and call transcripts. A flat AI-drafted MD&A narrative interrupts that model. The institutional reader does not always articulate the change, but the trust-line on the relationship moves down a notch and stays there.
Performance recaps and segment commentary tolerate templated phrasing because the numbers carry the message. Strategy paragraphs and forward-looking commentary do not; if the prose flattens, the institutional reader infers that the strategy itself is flatter than the prior letter claimed. Use the scan most aggressively on these paragraphs.
Letters and 10-K narrative pass through a disclosure committee at most public companies. Members include IR, legal, finance, and often the audit chair. AI-cadence prose surfaces inside that review as a soft problem: nothing breaks a specific rule, but the cadence prompts a closer read, the queue slows, and the committee starts asking authorship questions that did not used to come up. Pre-scanning removes that friction.
Pattern-flat sentence length, neutral verbs in place of operator-specific verbs ("optimise" instead of "renegotiate", "leverage" instead of "press"), and abstract claims that would normally carry a named driver in this management team's prior letters. The TextSight sentence highlights point at exactly these lines, which is the diagnostic the disclosure committee was already going to make on a slower review.
Conviction language is what institutional readers pay for. The detector cannot tell whether your thesis is right, but it can tell when the prose has stopped sounding like a person who believes the thesis.
Asset-manager voice on the systematic side tends toward precision: named factor exposures, explicit lookback windows, defined-risk language. Discretionary voice tends toward conviction: a named driver, a specific contrarian view, a particular operator the PM trusts. AI-assisted drafts often homogenise into a neutral middle that reads as neither and gets discounted by readers familiar with the manager's prior letters. The fix is to make one register dominant per piece and let it carry the prose.
Sell-side notes carry a recognisable structural rhythm: thesis paragraph, three to five driver sub-bullets with prose, valuation framework, key risks, recommendation. AI residue tends to appear in the driver-prose paragraphs as smooth transitional sentences with no channel-check texture. The fix is concrete sourcing per driver: a named distributor, a specific KPI, a quote from the management call, a specific industry contact's read.
Internal buy-side memos to a PM or an investment committee usually run shorter than sell-side notes and trade thoroughness for specificity. The flag points are the macro framing and the position-sizing rationale, where AI assistance tends to produce smooth prose with the wrong base-case anchor. Verify the framing against the team's prior IC memos before circulating.
The score is the diagnostic, not the goal. Rewriting a piece purely to lift the number tends to flatten the analyst voice that the desk and clients actually pay for. Use the sentence highlights to find specific lines that drift into stock phrasing, rewrite those, and let the headline number land wherever it lands.
Fintech editorial calibrates against two requirements at once: the substance has to read authoritative to a CFA-curious reader, and the language has to read accessible to a retail user who is opening a brokerage app for the first time. AI drafts collapse into a generic middle that fails both tests.
Neobanks, retail brokerages, robo-advisors, and personal-finance editorial outlets compete on the calibration between substance and accessibility. A piece that reads too academic loses the first-time investor; a piece that reads too breezy loses the reader who already knows what a bid-ask spread is. AI-assisted drafts default toward the middle of that range and read as commodity content to both audiences.
Use the scan on every public-facing fintech editorial piece. The Business tier with five seats and shared history fits an editorial team of two writers, an editor, a fact-checker, and a compliance reviewer; the audit log records who scanned what before sign-off. Marketing copy, landing pages, and customer-education email sequences route through the same loop. Verify regulated claims about returns, risk, and product features against the marketing rule, FINRA Rule 2210, or FCA promotion rules separately.
