Compyle
Compyle automates the data collection, historical research, and first-draft writing behind a Phase I ESA — drafts return the same day.
If your bottleneck is Phase I production, Compyle goes at the part that actually costs you money — the days of manual aerial, Sanborn, and directory research, plus the junior-EP first draft. The source-to-claim trail is the differentiator: every written claim and every surfaced REC is linked back to the record behind it, which is exactly the defensibility your senior reviewer needs before signing. Against ordering from EDR or ERIS, the same-day turnaround and self-collected historical record set are the real comparison. Be clear about the boundary: no Phase II, no compliance work, and the platform is browser-based. Demo it on one of your own addresses before you commit a backlog.

About Compyle
Compyle is an AI platform built specifically for Phase I Environmental Site Assessments under ASTM E1527-21. It does the desk work that normally consumes an environmental professional's week: it collects historical aerial photos (1968–2024, USGS and NETR), Sanborn fire insurance maps (1887–1951, Library of Congress), city directories (1920–1990, Ancestry and local archives), USGS topographic quads (1894–2021), and regulatory database records across federal, state, and tribal ASTM lists. Where an EDR or ERIS order runs 3–10 days, Compyle returns the data package the same day. After collection, the platform analyzes every aerial, Sanborn sheet, directory volume, and regulatory record to surface findings across the subject property and its neighbors — RECs, HRECs, and de minimis conditions among them. Each finding carries a 1:1 source-to-claim trail: the example on Compyle's own site traces a 1942–1978 Texaco service station finding to three named sources (Sanborn 1951 sheet 4, Portland City Directory 1955, and a 1963 aerial). Regulatory records are kept in a versioned, auditable file. Draft sections land in your firm's own report template and voice, and your EPs review them in the built-in editor — commenting, suggesting edits, approving section by section. Nothing ships without EP sign-off. It's aimed at environmental consulting firms that want more Phase I volume without more headcount, and it trades breadth for depth: it does Phase I exceptionally well and very little else.
Behind the Verdict
Compyle is a narrow tool, and that narrowness is the product. Rather than a general environmental-consulting suite, it implements one workflow end to end: the ASTM E1527-21 Phase I. Data collection pulls historical aerials (1968–2024), Sanborn fire insurance maps (1887–1951), city directories (1920–1990), USGS topographic quads (1894–2021), and regulatory database records from federal, state, and tribal lists — the record set the standard actually calls for — and returns them the same day instead of the 3–10 days an EDR or ERIS order takes. Strengths. The analysis layer runs across every source type, not just regulatory databases. Compyle's own worked example surfaces eight conditions on one property — five RECs, two HRECs, one de minimis — and each one names its evidence (a former on-site gasoline service station traced to Sanborn 1951 p.4, City Directory 1955, and an aerial from 1963). That traceability is the whole argument for letting an AI write any part of a Phase I: your EP is reviewing a sourced draft rather than checking a junior's line-by-line citations against raw files. The editor workflow matches how firms already QC — comments, suggested edits, section-level approval — and nothing ships without EP sign-off. Regulatory files are versioned and auditable, which matters if the report is ever challenged. Output lands in your template and voice rather than a Compyle-branded shell. Weaknesses and boundaries. This is Phase I only. There is no Phase II support, no compliance work, and no broader environmental scope — if your firm's work is general environmental consulting, this covers a slice of it. The platform is browser-based, so field teams needing a mobile app or offline access are out of scope. The AI drafts require EP review by design; if you want full manual control with no AI-generated text in your reports, this is the wrong tool. And the team is early — two engineers out of Hadrius (YC W23) — so you are buying into a young vendor's roadmap as much as its current capability. Where it fits. Small to mid-sized consulting firms with a Phase I backlog and not enough EPs or junior researchers to clear it. Firms spending real money on historical aerial, Sanborn, city directory, and regulatory record orders. Senior EPs who would rather review a sourced draft than write from scratch. Run it against one live address before you move a pipeline onto it — the quality of the source-to-claim trail on your own property is the only benchmark that matters.

Real-world workflow fit
Concrete scenarios for the personas Compyle actually fits — and what changes day-one when you adopt it.
You receive a new Phase I assignment on a former commercial parcel. You enter the address and Compyle collects the historical aerials, Sanborn maps, city directories, USGS quads, and regulatory records, then drafts the historical use, records review, and findings sections in your firm's template with each claim linked to its source.
Outcome: You spend your time reviewing a sourced draft — commenting and approving section by section — instead of waiting 3–10 days on an EDR or ERIS order and then writing the narrative yourself.
You have more Phase I work than your EPs can clear. You run multiple properties through Compyle in parallel, then route each drafted report to the responsible EP for review and sign-off in the built-in editor.
Outcome: Higher Phase I throughput per EP, without adding junior researchers or line-by-line QC hours against raw records.
A reviewer questions a REC call. You open the finding and follow its source-to-claim link back to the underlying Sanborn sheet, city directory volume, or regulatory record, and pull the versioned regulatory file.
Outcome: The finding is defensible on the record itself, not on someone's memory of what a file said.
Use Cases
- Collect all ASTM-required historical and regulatory records for a property in one day, not one to two weeks
- Draft Phase I ESA report sections in your firm's template and voice for EP review
- Identify and document RECs, HRECs, and de minimis conditions with a source link on each
- Trace every written claim back to the specific Sanborn sheet, directory volume, aerial, or regulatory record behind it
- Cut report production time from days to hours per assessment
- Take on more Phase I volume without hiring additional EPs or junior researchers
Limitations
- Compyle is purpose-built for Phase I ESA automation — data collection plus draft report generation — and every section still requires Environmental Professional review and approval.
- Scope stops at ASTM E1527-21 Phase I: there is no Phase II, no compliance work, and no broader environmental consulting scope.
- The platform is browser-based, with no evidence of an offline mode or mobile app, so field work is out of scope.
- Because output is an AI draft in your template, firms that want fully manual authorship with no AI text in the report are not a fit.
- Compyle is also an early-stage product from a small team (two engineers out of Hadrius, YC W23), so roadmap and support depth are worth probing on a demo.

Featured Head-to-Head Comparisons
Compyle vs Presto Voice
Presto Voice and Compyle serve completely different industries, so the choice comes down to your business: if you're a multi-location QSR chain aiming to boost revenue and efficiency via drive-thru voice AI, Presto Voice is the clear leader with proven results (e.g., Dairy Queen partnership). If you're an environmental consultant automating Phase I ESAs to cut turnaround time, Compyle's same-day data packages and AI drafting are game-changers. Both are enterprise-grade solutions with contact-based pricing; there is no cross-industry competition.
Compyle vs Screenplayiq
ScreenplayIQ and Compyle serve completely different industries and use cases. ScreenplayIQ is for screenwriters and studios needing script marketability analysis, while Compyle is for environmental professionals automating Phase I ESAs. Your choice depends solely on your field. Both leverage AI to streamline workflows, but they are not direct competitors.
Compyle vs Truleo
Truleo and Compyle serve completely different verticals. If you're in law enforcement needing to unify siloed data for quicker case leads, Truleo is the clear choice with features like jail call analysis and one-search. If you're an environmental consultant drowning in Phase I ESA paperwork, Compyle delivers same-day data packages and AI drafting that can cut turnaround from over a week to a single day. Choose based on your industry, not features.
