Formidable Forms vs Senja: at a glance
What is Formidable Forms?
Formidable Forms ships field-level abandonment drop-off graphs and conversational form drafts across its add-on ecosystem
Formidable is shipping a focused round of improvements across its add-on ecosystem: Abandonment v1.2 adds a drop-off graph showing field-level abandonment rates in the Reports tab, paired with draft save/resume for conversational forms. Stripe Forms v3.2 migrates to Stripe's current confirmCardPayment API. Conversational Forms v1.3 adds draft save/resume and start-over buttons. WPML Forms v2.0 redesigns the translation interface for per-language editing.
What is Senja?
Senja is closing the loop from collecting proof to producing the asset.
The dated window covers the merge of classic forms into forms 2.0, native Slack notifications, and an MCP server that connects Senja directly to an assistant. The undated rows fill in both ends of the story: a 2025 run that added AI sizzle reels, case studies from single testimonials, editable testimonial images and reusable video clips, and a 2026 run concentrated almost entirely on invites — performance tracking, editable follow-ups, quick invite, and Stripe events triggering the ask.

Formidable Forms ships field-level abandonment drop-off graphs and conversational form drafts across its add-on ecosystem
◆ Current state
Formidable is shipping a focused round of improvements across its add-on ecosystem: Abandonment v1.2 adds a drop-off graph showing field-level abandonment rates in the Reports tab, paired with draft save/resume for conversational forms. Stripe Forms v3.2 migrates to Stripe's current confirmCardPayment API. Conversational Forms v1.3 adds draft save/resume and start-over buttons. WPML Forms v2.0 redesigns the translation interface for per-language editing.
◆ Where it's heading
The consistent pattern is bringing conversational forms to feature parity with standard forms: draft save, start-over, abandonment tracking, and repeater support are all landing in the conversational forms path this cycle. The Formidable MCP server (Forms API v2.0.1, from the prior cycle) signals an upcoming AI-native direction — form data and submissions becoming accessible to AI agents via MCP is a distinct product surface that hasn't been fully exploited yet.
◆ Prediction
The next likely move is an AI-assisted form builder or response handler that leverages the MCP server foundation, given the established MCP compatibility layer and the trend toward AI-native WordPress tooling.
Senja
0.0MKT AUTO
Senja is closing the loop from collecting proof to producing the asset.
◆ Current state
The dated window covers the merge of classic forms into forms 2.0, native Slack notifications, and an MCP server that connects Senja directly to an assistant. The undated rows fill in both ends of the story: a 2025 run that added AI sizzle reels, case studies from single testimonials, editable testimonial images and reusable video clips, and a 2026 run concentrated almost entirely on invites — performance tracking, editable follow-ups, quick invite, and Stripe events triggering the ask.
◆ Where it's heading
Senja is building a pipeline rather than a widget. Collection is being automated and measured, the library is being turned into finished formats — reels, case studies, clips — and the MCP server exposes the whole thing to an assistant that can query it. The 2026 releases suggest the constraint they are working on now is volume at the top of the funnel, since every downstream format is only as good as the proof coming in.
◆ Prediction
With invites instrumented, the next obvious step is acting on the numbers — timing or targeting invites automatically off the tracking data, rather than adding more places to send them from.
