RobaerOS vs. Clerky: SAFE Review vs. Automated Legal Documents
Clerky is the default for startup formation legal documents — it gives you incorporation papers, founder stock agreements, 83(b) elections, and standardized SAFE templates through a guided wizard. RobaerOS is a SAFE-review tool that reads the document, extracts terms, scores risk, and models dilution. They sound similar. They aren't.
This page does an honest head-to-head: where the two tools overlap, where they don't, what RobaerOS does that Clerky doesn't, what Clerky does that RobaerOS can't, and how most founders end up using both.
TL;DR
- Different jobs. Clerky generates your outbound formation documents and SAFE templates; RobaerOS reads incoming investor-prepared SAFEs and flags non-standard terms. They answer different questions at different moments of a fundraise.
- Use Clerky first, at incorporation. Spin up your Delaware C-Corp, founder stock, 83(b) elections, and standardized outbound SAFE templates through Clerky's wizard. Most seed-stage founders should do this once, near day zero.
- Use RobaerOS the moment an investor sends you a SAFE. Drop in the SAFE, get term extraction, risk scoring, red flag detection, and a dilution preview in under 60 seconds — without paying a lawyer or manually transcribing into a spreadsheet.
- Founders who already use Clerky get the biggest benefit from adding RobaerOS: instant term review on every incoming investor-prepared SAFE, especially the ones drafted by investor counsel outside Clerky's templates.

Automated Startup Legal Documents
Generates incorporation papers, founder agreements, 83(b) elections, and standardized SAFE templates. Does not read incoming investor-prepared SAFEs or flag non-standard terms before signing.

Where RobaerOS and Clerky Overlap
The honest truth: there's a narrow slice where both tools do something similar, and it's worth being precise about that slice so you're not paying for two tools to do the same job.
Outbound SAFE templates. Both RobaerOS and Clerky can help you generate a SAFE you send to an investor. Clerky does it through a guided wizard with conditional fields and built-in defaults, producing a clean Clerkymanaged template you e-sign through Clerky's flow in roughly 10 minutes. RobaerOS ships a printable template walkthrough and a public library of standardized examples, but does not produce a completed PDF or wire it into a signing flow. If your only need is "produce a SAF-E-template-and-sign-it-with-a-Cap-table-friendly-document," Clerky wins hands-down — that's the workflow it was built for.
Where the overlap breaks. Clerky's wizard is great at producing its own templates, but if an investor sends you a SAFE drafted outside Clerky (which is most institutional SAFE prep), Clerky won't surface anything unusual before you sign. That includes non-standard MFN clauses, custom pro-rata mechanics, unusual conversion triggers, and side letters embedded in cover documents. If the SAFE came from a fund's counsel, you should run it through RobaerOS before signing, regardless of who produced your outbound docs.
Outside that narrow overlap, the two tools address genuinely different problems.
What RobaerOS Does That Clerky Doesn't
RobaerOS exists because there's a step in every fundraise that automated document platforms don't perform: reading the SAFE before you sign it. That step is currently done by lawyers (slow, expensive), or not at all (fast, risky).
Term extraction from a real document
Upload a SAFE in any format — PDF, Word, pasted text, or a Clerky export — and RobaerOS extracts the cap, discount, MFN clause, pro-rata language, conversion trigger, and any side-letter material. The output is a plain-English breakdown of what the document actually says, including provisions the founder didn't know were in there.
Risk scoring by term
Each extracted term is scored against benchmarks drawn from thousands of SAFE agreements. A discount of 20% on a $3M cap is a different proposal than 20% on a $10M cap. A pro-rata clause with a 30-day window is a different proposal than one with a 90-day window. RobaerOS tells you what each number means in context.
Red flag detection
Non-standard provisions — shadow MFN clauses, custom pro-rata mechanics, unusual conversion triggers, side-letter grants — show up in plain English with explanations of why each is unusual and what to ask about it. Founders who skip this step cite the same regret: "I wish I'd asked about the side letter before signing."
Dilution preview without data entry
RobaerOS shows what an investor's post-conversion ownership will be at a modeled Series A price, without requiring you to enter anything into a formation platform or cap table. This is the moment founders most often mis-model — because they're computing dilution on terms they read once and forgot, rather than on the document itself.
Side-by-Side: Reviewing an Incoming SAFE
Clerky workflow: Receive SAFE → it isn't a Clerky template → Clerky can't help — it doesn't read inbound language → forward to lawyer → wait 3–5 days → receive $1,500 memo → e-sign through Clerky after a manual term confirmation. Clerky's SAFE wizard takes ~10 minutes to generate a new SAFE, but assumes you've already correctly drafted or selected the terms yourself.
RobaerOS workflow: Receive SAFE → drop it in RobaerOS → 60 seconds → see extracted terms, risk scores, red flags, dilution preview. If anything is non-standard, forward only that SAFE to a lawyer with the list of questions. If clean, e-sign through Clerky and move on.
Both workflows reach the same signed agreement. Only one of them tells you what the SAFE actually says before you sign — and only one of them flags the terms the lawyer's letter would have surfaced anyway.
What Clerky does that RobaerOS doesn't
RobaerOS doesn't generate incorporation papers. It doesn't draft your founder stock agreements, your 83(b) election letters, your board consents, or your standard SAFE template. Clerky does all of those — especially the "spin up a Delaware C-Corp with proper founder docs in an afternoon" workflow, which is genuinely useful for pre-seed founders who don't have a lawyer yet. The mistake founders make is treating a document-generation platform as a term-review tool.
When to Use RobaerOS vs. When to Use Clerky
- Use Clerky at incorporation — Delaware C-Corp formation, founder stock, 83(b) elections, board consents, your outbound SAFE templates.
- The moment an investor sends you a SAFE, drop it in RobaerOS. Get the plain-English read, the risk score, the red flags, and the dilution preview.
- Confirm the terms with a lawyer for any non-standard SAFE — RobaerOS surfaces which ones those are, so the lawyer conversation is targeted, not exploratory.
- Sign the SAFE through Clerky's e-signature flow. At this point you know what you're signing.
- Next SAFE? RobaerOS again. Each incoming SAFE is reviewed in 60 seconds; only the unusual ones go to a lawyer; clean ones e-sign through Clerky.
Treating Clerky as a term-review tool. Clerky generates documents — it doesn't read incoming SAFE language, identify non-standard provisions, or surface terms the inbound investor's counsel drafted. Use a dedicated review tool (RobaerOS) before signing anything that didn't come from a Clerky template; use Clerky for everything else.
