Needles vs Filevine

The short version

Needles has been a fixture in PI firms for years, installed on the firm's own server. Its maker, Assembly Software, now steers Needles firms to Neos, its browser-based successor. So "Needles vs Filevine" is really a choice between staying in the Assembly family by moving to Neos, or switching platforms to Filevine.

Needles and Neos

Needles runs on-premise: cases sit on a local server, and working remotely usually means a VPN or remote desktop and help from IT. Assembly's site places Needles in a legacy section and describes Neos as built by the same team on the same PI case logic, running in a browser with no server to maintain.

Assembly reports that 440 former Needles firms have moved to Neos, and says its migration team moves case files, documents, client records and case history. It says most firms are fully operational within a few weeks of go-live, with timing set by firm size and data.

Neos comes in tiers. Third-party listings disagree slightly on price: about $99 to $109 per user per month for Essentials, $129 to $139 for Premium, and $179 to $189 for NeosAI Platinum. Premium adds OCR, Bates stamping and redaction; Platinum adds NeosAI (demand letters, chronologies and summaries from the case file), texting and dynamic intake forms. These are third-party figures; confirm with Assembly.

Filevine

Filevine is a cloud platform that announced $400M raised and nearly 6,000 customers in September 2025. It serves PI, mass torts and many other practices, and sells packages for matters, intake (Lead Docket), depositions, e-signature and its LOIS AI, including MedChron, DemandsAI and LOIS Console, which runs agents across every matter. Its Depositions package covers scheduling, hosting and AI deposition summaries. Its pricing page also lists a free LOIS tier, LOIS Explore, which does not include case management.

Filevine is custom-quoted. A third-party guide estimates about $65 to $100 per user per month and $5,000 to $20,000 to implement. A vendor's guide citing G2 buyer data puts Filevine's average implementation at about four months.

What a Needles firm should weigh

1. Continuity. Neos keeps the case logic your staff know, and Assembly does the migration. That is the lowest-risk move.
2. Breadth. Filevine offers more configuration and its own intake and deposition products, at the cost of a larger change for staff.
3. AI. Both now include AI for chronologies and demands. Compare outputs on the same closed file.
4. Lead Docket. It integrated with Needles when Filevine bought it, and Filevine owns it, so firms using it may have a path either way; confirm the current integration.
5. Old documents. Years of scanned records and faxes move with you. Ask each vendor what its AI can read from them, and what needs OCR first.
6. Total cost. Compare a year of Neos at your tier and headcount against a written Filevine quote with implementation, migration, training and AI included.

Before committing, ask Assembly and Filevine for a written migration plan: what moves (cases, notes, documents, calendars, custom fields), what doesn't, how long the cutover takes, and who checks the result. Ask to speak to a firm that made the same move in the last year.

Which one fits which firm

Choose Neos (from Needles) if your team is comfortable with Needles' way of working and you want the cloud with the least disruption.

Choose Filevine if you want to rethink workflows, run several practices, or want case management, intake and AI from one vendor.

Where PlaintiffStack fits

For a California firm leaving a Needles server, PlaintiffStack is a third path. We move your cases, contacts and documents and check the result with you before you switch. It is case management with AI built in for California PI, workers' comp and employment, at $250 per case with every app included and no monthly fee; AI usage is billed separately, with an estimated cost before each run. One gap to plan for: it reads searchable PDFs, Word and text files only, with no OCR yet, so scanned records from an older system are not read by the AI.
